 Exhibit 10.3 

CHANGE IN CONTROL AGREEMENT 

This Change in Control Agreement (this “Agreement”) is by and among McDermott International, Inc. (the “Company”),
[●] (the “Employer”), and [●] (“Executive”). 
 The Company and the Employer consider it essential to the
interests of the Company’s stockholders to secure the continued employment of key management personnel. The Board of Directors of the Company recognizes that the possibility of a Change in Control (as defined in Exhibit A) exists and
that the uncertainty this raises may result in the departure or distraction of management personnel to the detriment of the Company and its stockholders. In order to encourage the continued attention and dedication of key management personnel, this
Agreement is being entered into by the Company, the Employer and Executive. 
 The Company, the Employer and Executive agree as follows:

  

	1.	 DEFINITIONS. Capitalized terms used but not otherwise defined herein are defined
in Exhibit A hereto. 

  

	2.	 SEVERANCE BENEFITS. 

 

	 	(a)	 Entitlement to Benefits If Executive experiences a Covered Termination and executes a Waiver and
Release in accordance with Section 2(b) below that is no longer subject to rescission, Executive will be entitled to the following: 

  

	 	(i)	 Accrued Benefits. The Accrued Benefits, payable on the 60th day after the Covered Termination
Date, or such earlier date as may be required by applicable law. 

  

	 	(ii)	 EDCP. As of the Covered Termination Date, a fully vested and
non-forfeitable interest in Executive’s account balance in the EDCP, payable in accordance with the terms of the EDCP. 

 

	 	(iii)	 Unvested Equity-Based Awards. As of the Covered Termination Date, unless otherwise settled in
accordance with the provisions of Section 3 of this Agreement and the plans and agreements referred to therein, a fully vested and non-forfeitable interest in any outstanding unvested equity-based awards,
and to the extent applicable, payable on the 60th day after the Covered Termination Date; provided that no such award that is subject to Code Section 409A will be paid on a date earlier than is provided in the applicable plan and award
agreement. 

  

	 	(iv)	 Severance Payment Based on Salary. An amount equal to two (2) times the sum of (i) the
Salary, and (ii) Executive’s target award under the EICP for the year in which the Covered Termination Date occurs, in a lump sum in cash on the 60th day after the Covered Termination Date. 

  
 1 

	 	(v)	 Severance Payment Based on Bonus. 

 

	 	(1)	 Current Performance Year. An amount equal to the product of (A) the Salary and (B) the
Target Bonus Percentage, with the product of (A) and (B) prorated based on the number of days Executive was employed during the bonus year in which Executive’s Covered Termination Date occurs, in a lump sum in cash on the 60th day after
the Covered Termination Date. 

  

	 	(2)	 Prior Performance Year. If a bonus is paid under the EICP after Executive’s Covered
Termination Date occurs for the immediately preceding calendar year, then Executive will be entitled to an amount equal to the product of (A) the Salary and (B) the Target Bonus Percentage (or, if greater, the actual amount of the bonus
determined under the EICP for such prior calendar year), in a lump sum in cash at the later of (i) the 60th day after the Covered Termination Date and (ii) the time such bonus is paid to other EICP participants. 

 

	 	(vi)	 Other Compensation. The Other Compensation payable or provided in the manner and time specified
in applicable documents governing such amounts. 

  

	 	(b)	 Waiver and Release. Notwithstanding any provision of this Agreement to the contrary, in order to
receive the severance benefits payable under any provision of Section 2(a)(ii), (iii), (iv) and (v) of this Agreement, Executive must first execute an appropriate waiver and release agreement in a form acceptable to the Company (a
currently acceptable form is attached hereto as Exhibit B (the “Waiver and Release”)), whereby Executive shall agree to release and waive, in return for such severance benefits, any claims that Executive may have
against the Company and the Employer and their respective Affiliates, directors, officers and other customary persons from any claim or liability arising out of or related to Executive’s employment with or termination of employment from the
Employer and any of its Affiliates (except for amounts to which Executive is legally entitled pursuant to employee benefit plans and rights to indemnification); provided, however, such Waiver and Release shall not release any claim or cause of
action by or on behalf of Executive for any payment or vested benefit that is due under either this Agreement or any employee benefit plan or program of the Company or the Employer until fully paid prior to the receipt thereof. Executive shall have
21 days (or 45 days, if applicable, as determined by the Company) after receipt of the Waiver and Release to consider and timely execute and return it to the Company. After return, Executive shall have an additional seven days in which Executive can
revoke the Waiver and Release; thereafter, the Waiver and Release shall be irrevocable. The Company or the Employer shall provide the Waiver and Release to Executive no later than five days after his Termination Date. If the Waiver and Release is
not timely executed and returned, or if it is revoked within the seven-day revocation period, no benefits shall be paid under this Agreement except those to which the Executive has a vested interest without
regard to Section 2(a) of this Agreement. 

  
 2 

	 	(c)	 Reduction to Avoid Parachute Taxes. Exhibit C hereto sets forth the manner of reduction to
be applied to avoid parachute taxes. 

 In no event shall the payments or benefits provided for in Sections 2(a)(i),
2(a)(iii), 2(a)(iv) and 2(a)(v) above that are not subject to Code Section 409A be paid later than March 15th of the calendar year immediately following the calendar year in which Executive’s Covered Termination Date occurs. 

 

	3.	 CHANGE IN CONTROL EQUITY-BASED
BENEFITS. If a Change in Control occurs, any benefits Executive may be entitled to with respect to any equity-based compensation shall be determined in accordance with the applicable plans and award agreements. In the event of any
conflict between the terms of any such plan or award agreement and Section 2(a)(iii) of this Agreement, the terms of such plan or award agreement shall control. 

 

	4.	 INTERNAL REVENUE CODE
SECTION 409A. 

  

	 	(a)	 Compliance. It is the intent of the parties that the provisions of this Agreement either comply
with Code Section 409A and the Treasury regulations and guidance issued thereunder or that one or more elements of compensation or benefits be exempt from Code Section 409A. Accordingly, the parties intend that this Agreement be
interpreted and operated in a manner consistent with such requirements in order to avoid the application of penalty taxes under Code Section 409A to the extent reasonably practicable. The Company and the Employer shall neither cause nor permit:
(i) any payment, benefit or consideration to be substituted for a benefit that is payable under this Agreement if such action would result in the failure of any amount that is subject to Code Section 409A to comply with the applicable
requirements of Code Section 409A; or (ii) any adjustments to any equity interest to be made in a manner that would result in the equity interest’s becoming subject to Code Section 409A unless, after such adjustment, the equity
interest is in compliance with the requirements of Code Section 409A to the extent applicable. A Covered Termination is an “involuntary separation from service” for purposes of Code Section 409A. 

 

	 	(b)	 Waiting Period for Specified Employees. Notwithstanding any provision of this Agreement to the
contrary, if Executive is a “Specified Employee” (as that term is defined in Code Section 409A) as of Executive’s Covered Termination Date, then any amounts or benefits which are payable under this Agreement upon Executive’s
“Separation from Service” (within the meaning of Code Section 409A), which are subject to the provisions of Code Section 409A and not otherwise excluded under Code Section 409A, and would otherwise be payable during the
first six-month period following such Separation from Service, shall be paid on the first business day that (i) is at least six months after the date after Executive’s Covered Termination Date or
(ii) follows Executive’s date of death, if earlier. 

  
 3 

	5.	 CONFIDENTIALITY AND NON-DISCLOSURE. 

  

	 	(a)	 Executive acknowledges that, pursuant to this Agreement, the Company and the Employer agree to provide
Executive with Confidential Information regarding the Company and the Employer and their respective businesses and have previously provided Executive other such Confidential Information. In return for this and other consideration provided under this
Agreement, Executive agrees that Executive will not, while employed by the Employer or any of its Affiliates and thereafter, disclose or make available to any other person or entity, or use for Executive’s own personal gain, any Confidential
Information, except for such disclosures as required in the performance of Executive’s duties hereunder as may otherwise be required by applicable law or legal process (in which case Executive shall notify the Company and the Employer of such
legal or judicial proceeding as soon as practicable following Executive’s receipt of notice of such a proceeding, and permit the Company and the Employer to seek to protect its interests and information). For purposes of this Agreement,
“Confidential Information” shall mean any and all information, data and knowledge that has been created, discovered, developed or otherwise become known to the Company, the Employer or any of their respective Affiliates or ventures or in
which property rights have been assigned or otherwise conveyed to the Company, the Employer or any of their respective Affiliates or ventures, which information, data or knowledge has commercial value in the business in which the Company, the
Employer or any of their respective affiliates is engaged, except such information, data or knowledge as is or becomes known to the public without Executive’s violation of any of the terms of this Section 5. By way of illustration, but not
limitation, Confidential Information includes business trade secrets, secrets concerning the Company’s and the Employer’s plans and strategies, nonpublic information concerning material market opportunities, technical trade secrets,
processes, formulas, know-how, improvements, discoveries, developments, designs, inventions, techniques, marketing plans, manuals, records of research, reports, memoranda, computer software, strategies,
forecasts, new products, unpublished financial information, projections, licenses, prices, costs, and employee, customer and supplier lists or parts thereof. 

  

	 	(b)	 Nothing in this Agreement shall prohibit or restrict Executive from lawfully (i) initiating communications
directly with, cooperating with, providing information to, causing information to be provided to, or otherwise assisting in an investigation by any governmental or regulatory agency, entity, or official(s) (collectively, “Governmental
Authorities”) regarding a possible violation of any law; (ii) responding to any inquiry or legal process directed to Executive individually from any such Governmental Authorities; (iii) testifying, participating or otherwise assisting
in an action or proceeding by any such Governmental Authorities relating to a possible violation of law; or (iv) making any other disclosures that are protected under the whistleblower provisions of any

  
 4 

	 	
applicable law. Additionally, pursuant to the federal Defend Trade Secrets Act of 2016, Executive shall not be held criminally or civilly liable under any federal or state trade secret law for
the disclosure of a trade secret that: (i) is made (A) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney; and (B) solely for the purpose of reporting or investigating a
suspected violation of law; or (ii) is made to Executive’s attorney in relation to a lawsuit for retaliation against Executive for reporting a suspected violation of law; or (iii) is made in a complaint or other document filed in a
lawsuit or other proceeding, if such filing is made under seal. This Agreement does not require Executive to obtain prior authorization from the Company before engaging in any conduct described in this paragraph, or to notify the Company that
Executive has engaged in any such conduct. 

  

	6.	 RETURN OF PROPERTY. Executive agrees that at the time of
Executive’s leaving employ with the Employer or any of its Affiliates, Executive will deliver to the Employer (and will not keep in his possession, recreate or deliver to anyone else) all Confidential Information as well as all other devices,
records, data, notes, reports, proposals, lists, correspondence, specifications, drawings, blueprints, sketches, materials, equipment, customer or client lists or information, or any other documents or property (including all reproductions of the
aforementioned items) belonging to the Company, the Employer or any of their respective Affiliates, regardless of whether such items were prepared by Executive. 

 

	7.	 NON-SOLICITATION.

  

	 	(a)	 Executive agrees to the non-solicitation provisions of this
Section 7: (i) in consideration for the Confidential Information provided by the Company to Executive; and (ii) to protect the Confidential Information of the Company disclosed or entrusted to Executive by the Company or created or
developed by Executive for the Company, the business goodwill of the Company developed through the efforts of Executive and the business opportunities disclosed or entrusted to Executive by the Company. Executive agrees that in the event that
Executive fails to comply with any of the provisions of this Section 7, Executive will repay to the Company any payments received pursuant to this Agreement and no further benefits will be payable to Executive under this Agreement.

  

	 	(b)	 Executive agrees that, while employed by the Employer or any of its Affiliates and for 12 months following a
Covered Termination or any termination of employment by Executive, Executive shall not, without the prior written consent of the Company and the Employer, directly or indirectly, (i) hire or induce, entice or solicit (or attempt to induce,
entice or solicit) any employee of the Company, the Employer or any of their respective Affiliates or ventures to leave the employment of the Company, the Employer or any of their respective Affiliates or ventures or (ii) solicit or attempt to
solicit the business of any customer or acquisition prospect of the Company, the Employer or any of their respective Affiliates or ventures with whom Executive had any actual contact while employed at the Employer. 

  
 5 

	 	(c)	 Executive acknowledges that these restrictive covenants under this Agreement, for which Executive received
valuable consideration from the Company and the Employer as provided in this Agreement, including, but not limited to the agreement of the Company and the Employer to provide Executive with Confidential Information are ancillary to otherwise
enforceable provisions of this Agreement, that the consideration provided by the Company and the Employer gives rise to the interest of each of the Company and the Employer in restraining Executive and that the restrictive covenants are designed to
enforce Executive’s consideration or obligations under this Agreement. Additionally, Executive acknowledges that these restrictive covenants contain limitations as to time and scope of activity to be restrained that are reasonable and do not
impose a greater restraint than is necessary to protect the goodwill or other legitimate business interests of the Company and the Employer, including, but not limited to, the Company’s and the Employer’s need to protect their Confidential
Information. 

  

	 	(d)	 Executive acknowledges and agrees that in the event of any breach by Executive of any of Executive’s
covenants or agreements contained herein, including, without limitation, a breach of Section 5, 6 or 7, the Company would suffer substantial and irrevocable harm and money damages would not be a sufficient remedy for such a breach. Therefore,
in the event of any such breach and in addition to any other remedy the Company may have at law or in equity in the event of any such breach, the Company shall be entitled to seek and receive specific performance and temporary, preliminary and
permanent injunctive relief from any breach of any of the covenants or agreements of this Agreement from any court of competent jurisdiction without the necessity of proving the amount of any actual damages to it resulting from such breach.

  

	8.	 NOTICES. For purposes of this Agreement, notices and all other communications must be in

failure by the Company or the Employer to continue Executive’s participation therein (or in such substitute or alternative plan) on a basis not materially less favorable than existed immediately before the Change in Control, unless the action
by the Company or the Employer applies to all similarly situated employees; 

  

	 	(d)	 the failure by the Company and the Employer to continue to provide Executive with material benefits in the
aggregate that are substantially similar to those enjoyed by Executive under any of the Company’s (or the Employer’s or their respective Affiliates’) pension, savings, life insurance, medical, health and accident, or disability plans
in which Executive was participating immediately before the Change in Control if such benefits are material to Executive’s total compensation, the taking of any other action by the Company or the Employer which would directly or indirectly
materially reduce any of such benefits or deprive Executive of any fringe benefit enjoyed by Executive at the time of the Change in Control if such fringe benefit is material to Executive’s total compensation, unless the action by the Company
or the Employer applies to all similarly situated employees; or 

  

	 	(e)	 a change in the location of Executive’s principal place of employment with the Employer or the Company by
more than 50 miles from the location where Executive was principally employed immediately before the Change in Control without Executive’s consent. 

If a Change in Control occurs and any of the events described above occurs prior to the first anniversary of such Change in Control (an
“Event”), Executive shall give the Company written notice (the “Executive Notice”) within 60 days following Executive’s knowledge of an Event that Executive intends to terminate employment as a result. The Company shall have
30 days following receipt of the Executive Notice in which to cure the Event. If the Company does not take such action within that time, the Event shall constitute Good Reason. If Executive does not provide the Executive Notice within 60 days as
required above then the Event shall not constitute Good Reason, and thereafter, for purposes of determining whether Executive has Good Reason, Executive’s terms and conditions of employment after the occurrence of the Event shall be substituted
for those terms and conditions of Executive’s employment in effect immediately prior to the date of this Agreement. 

  
 A-6 

 “Other Compensation” shall mean all payments and benefits to which
Executive may be entitled under the terms of any applicable compensation arrangement or benefit plan or program of the Company that do not specify the time of distribution, other than such payments and benefits provided for under
Section 2(a)(i) through Section 2(a)(v) of this Agreement; provided that Other Compensation shall not include any entitlement to severance under any severance policy of the Company generally applicable to the salaried employees of the
Company. 
 “Salary” means Executive’s annual base salary as in effect immediately before the termination of
Executive’s employment or, if higher, the base salary in effect immediately before the first event or circumstance constituting Good Reason. 

“Target Bonus Percentage” means Executive’s target incentive award opportunity under the EICP in effect immediately
before the termination of Executive’s employment or, if higher, immediately before the first event or circumstance constituting Good Reason.

FORM WAIVER AND RELEASE 

Pursuant to the terms of the Change in Control Agreement made as of March 16, 2019, by and among McDermott International, Inc. (the
“Company”), [●] (the “Employer”) and me, and in consideration of the payments made to me and other benefits to be received by me pursuant thereto, I, [●], do freely and voluntarily enter into this WAIVER AND RELEASE
(the “Release”), which shall become effective and binding on the eighth day following my signing the Release as provided herein (the “Effective Date”). It is my intent to be legally bound, according to the terms set forth below.

 In exchange for the payments and other benefits to be provided to me by the Company and the Employer pursuant to Section 2 of the Change in Control
Agreement (the “Separation Payment” and “Separation Benefits”), I hereby agree and state as follows: 
  

	1.	 I, individually and on behalf of my heirs, personal representatives, successors, and assigns, release, waive,
and discharge the Company and the Employer, their respective predecessors, successors, parents, subsidiaries, merged entities, operating units, affiliates, divisions, insurers, administrators, trustees, and the agents, representatives, officers,
directors, shareholders, employees and attorneys of each of the foregoing (hereinafter, “Released Parties”), both individually and in their official capacities, from all claims, debts, liabilities, demands, obligations, promises, acts,
agreements, costs, expenses, damages, actions, and causes of action, whether in law or in equity, whether known or unknown, suspected or unsuspected, arising from my employment and termination from employment with the Employer and its affiliates,
including, but not limited to, any and all claims pursuant to Title VII of the Civil Rights Act of 1964, as amended by the Civil Rights Act of 1991 (42 U.S.C. § 2000e, et seq.), which prohibits discrimination in employment based on race,
color, national origin, religion or sex; the Civil Rights Act of 1866 (42 U.S.C. §§1981, 1983 and 1985), which prohibits violations of civil rights; the Age Discrimination in Employment Act of 1967, as amended, and as further amended by
the Older Workers Benefit Protection Act (29 U.S.C. §621, et seq.), which prohibits age discrimination in employment; the Employee Retirement Income Security Act of 1974, as amended (29 U.S.C. § 1001, et seq. ), which
protects certain employee benefits; the Americans with Disabilities Act of 1990, as amended (42 U.S.C. § 12101, et seq.), which prohibits discrimination against the disabled; the Family and Medical Leave Act of 1993 (29 U.S.C. §

regulations regarding employment or compensation or prohibiting employment discrimination, or pursuant to any contract I may have with the Released Party, including the Change in Control Agreement [and
            ]; provided that the foregoing release shall not apply to any right explicitly set forth in the Change in Control Agreement to any payments and benefits to be provided in
connection with the termination of my employment. This Release also includes, but is not limited to, a release of any claims for breach of contract, mental pain,

suffering and anguish, emotional upset, impairment of economic opportunities, unlawful interference with employment rights, defamation, intentional or negligent infliction of emotional distress,
fraud, wrongful termination, wrongful discharge in violation of public policy, breach of any express or implied covenant of good faith and fair dealing, that the Company, the Employer or any of their respective Affiliates has dealt with me unfairly
or in bad faith, and all other common law contract and tort claims. This Release is not intended to indicate that any such claims exist or that, if they do exist, they are meritorious. Rather, I am simply agreeing that, in exchange for the
consideration received by me through this Release, any and all Released Claims that I may have against any Released Party, regardless of whether they actually exist, are expressly settled, compromised and waived. This Release includes matters
attributable to the sole or partial negligence (whether gross or simple) or other fault, including strict liability, of any Released Party. 

Notwithstanding the foregoing, I am not waiving any rights or claims that may arise after this Release is signed by me. Moreover, this Release
does not apply to any claims or rights which, by operation of law, cannot be waived. Nothing in this Release shall affect in any way my rights of indemnification and directors and officers liability insurance coverage provided to me pursuant to the
Company’s by-laws and/or pursuant to any agreement in effect prior to the effective date of my termination, which shall continue in full force and effect, in accordance with their respective terms,

Company, the Employer, their respective affiliates, or any current or former officer, director or employee of the Company, the Employer or any of their respective affiliates. However, I understand that nothing in this Release prohibits me from
filing a charge with, or reporting possible violations of federal law or regulation to any governmental agency or entity, including, but not limited to, the U.S. Equal Opportunity Commission, the Department of Justice, the Securities and Exchange
Commission, Congress, and any Inspector General, or making other disclosures that are protected under the whistleblower provisions of federal law or regulation. Nothing in this Release limits my ability to communicate with any government agencies or
participate in any investigation or proceeding that may be conducted by any government agency, including providing documents or other information, without notice to the Company. I understand that I will not be in breach of the covenant contained in
this paragraph solely by reason of my testimony which is compelled by process of law. 

  
 B-2 

	5.	 I hereby acknowledge and affirm as follows: 

 

	 	a.	 I have been advised to consult with an attorney prior to signing this Release and have had adequate opportunity
to do so.

	 	f.	 I have carefully read the contents of this Release and I understand its contents. I am executing this Release
voluntarily, knowingly, and without any duress or coercion. 

  

	6.	 I acknowledge that this Release shall not be construed as an admission by any of the Released Parties of any
liability whatsoever, or as an admission by any of the Released Parties of any violation of my rights or the rights of any other person, or any violation of any order, law, statute, duty or contract. 

 

	7.	 I agree that the terms and conditions of this Release are confidential and that I will not, directly or
indirectly, disclose the existence of or terms of this Release to anyone other than my attorney or tax advisor, except to the extent such disclosure may be required for accounting or tax reporting purposes or otherwise be required by law or
direction of a court. Nothing in this provision shall be construed to prohibit me from disclosing this Release to the Equal Employment Opportunity Commission in connection with any complaint or charge submitted to that agency.

	8.	 In the event that any provision of this Release should be held void, voidable, or unenforceable, the remaining
portions shall remain in full force and effect. 

  

	9.	 I hereby declare that this Release constitutes the entire and final settlement between me and the Company and
the Employer, superseding any and all prior agreements, and that neither the Company nor the Employer has made any promise or offered any other agreement, except those expressed in this Release, to induce or persuade me to enter into this Release.

 EXHIBIT C 

Excise Tax Modified Cutback Provisions 

Anything in this Agreement to the contrary notwithstanding, in the event the Firm (as defined below) shall determine that Executive shall
become entitled to payments and/or benefits provided by this Agreement which would be subject to the excise tax imposed by Code Section 4999 (the “Payments”), the Firm shall determine whether to reduce any of the Payments to
the Reduced Amount (as defined below). The Payments shall be reduced to the Reduced Amount only if the Firm determines that Executive would have a greater Net After-Tax Receipt (as defined below) of aggregate
Payments if the Executive’s Payments were reduced to the Reduced Amount. If such a determination is not made by the Firm, Executive shall receive all Payments to which Executive is entitled under this Agreement. 

If the Firm determines that aggregate Payments should be reduced to the Reduced Amount, the Company shall promptly give Executive notice to
that effect and a copy of the detailed calculation thereof. All determinations made by the Firm under this Exhibit C shall be binding upon the Company and Executive absent manifest error and shall be made as soon as
reasonably practicable but in no event later than 15 business days of the receipt of notice from the Company that there has been a Payment, or such earlier time as is requested by the Company. For purposes of reducing the Payments to the Reduced
Amount, only amounts payable under this Agreement (and no other Payments) shall be reduced. The reduction of the amounts payable hereunder, if applicable, shall be made by reducing, in order, cash payments otherwise due under Sections 2(a)(iv),
2(a)(v)(1) and 2(a)(v)(2) of this Agreement, and then by reducing equity-based compensation otherwise due under Section 2(a)(iii) of this Agreement in chronological order with the most recent equity based compensation awards reduced first. 

As a result of the uncertainty in the application of Code Section 4999 at the time of the initial determination by the Firm hereunder, it
is possible that amounts will have been paid or distributed by the Company to or for the benefit of Executive pursuant to this Agreement which should not have been so paid or distributed (“Overpayment”) or that additional amounts
which will have not been paid or distributed by the Company to or for the benefit of Executive pursuant to this Agreement could have been so paid or distributed (“Underpayment”), in each case, consistent with the calculation of the
Reduced Amount hereunder. In the event that the Firm, based upon the assertion of a deficiency by the Internal Revenue Service against either the Company or Executive which the Firm believes has a high probability of success determines that an
Overpayment has been made, Executive shall pay any such Overpayment to the Company together with interest at the applicable federal rate provided for in Code Section 7872(f)(2); provided, however, that no amount shall be payable by
Executive to the Company if and to the extent such payment would not either reduce the amount on which Executive is subject to tax under Code Sections 1 and 4999 or generate a refund of such taxes. In the event that the Firm, based upon controlling
precedent or substantial authority, determines that an Underpayment has occurred, any such Underpayment shall be paid promptly (but in no event later than 60 days following the date on which the Underpayment is determined) by the Company to or for
the benefit of Executive together with interest at the applicable federal rate provided for in Code Section 7872(f)(2). 

  
 C-1 

 For purposes hereof, the following terms have the meanings set forth below: 

“Firm” shall mean an internationally recognized accounting or employee benefits consulting firm selected by
the Company with the input of Executive (but without Executive’s consent) and which shall not, during the one year preceding the date of its selection, have acted in any way on behalf of the Company or its affiliated companies. 

“Net After-Tax Receipt” shall mean the present value (as determined in
accordance with Code Sections 280G(b)(2)(A)(ii) and 280G(d)(4)) of a Payment net of all taxes imposed on Executive with respect thereto under Code Sections 1 and 4999 and under applicable state and local laws, determined by applying the highest
marginal rate under Code Section 1 and under state and local laws which applied to the Executive’s taxable income for the immediately preceding taxable year, or such other rate(s) as Executive certifies, in Executive’s sole
discretion, as likely to apply to Executive in the relevant tax year(s). 
 “Reduced Amount” shall mean the
greatest amount of Payments that can be paid that would not result in the imposition of the excise tax under Code Section 4999 if the Firm determines to reduce Payments pursuant to the first paragraph of this Exhibit C. 

  
 C-2EX-10.4

 Exhibit 10.4 

CHANGE IN CONTROL AGREEMENT 

This Change in Control Agreement (this “Agreement”) is by and among McDermott International, Inc. (the “Company”),
[●] (the “Employer”), and [●] (“Executive”). 
 The Company and the Employer consider it essential to the
interests of the Company’s stockholders to secure the continued employment of key management personnel. The Board of Directors of the Company recognizes that the possibility of a Change in Control (as defined in Exhibit A) exists and
that the uncertainty this raises may result in the departure or distraction of management personnel to the detriment of the Company and its stockholders. In order to encourage the continued attention and dedication of key management personnel, this
Agreement is being entered into by the Company, the Employer and Executive. 
 The Company, the Employer and Executive agree as follows:

  

	1.	 DEFINITIONS. Capitalized terms used but not otherwise defined herein are defined
in Exhibit A hereto. 

  

	2.	 SEVERANCE BENEFITS. 

 

	 	(a)	 Entitlement to Benefits If Executive experiences a Covered Termination and executes a Waiver and
Release in accordance with Section 2(b) below that is no longer subject to rescission, Executive will be entitled to the following: 

  

	 	(i)	 Accrued Benefits. The Accrued Benefits, payable on the 60th day after the Covered Termination
Date, or such earlier date as may be required by applicable law. 

  

	 	(ii)	 EDCP. As of the Covered Termination Date, a fully vested and
non-forfeitable interest in Executive’s account balance in the EDCP, payable in accordance with the terms of the EDCP. 

 

	 	(iii)	 Unvested Equity-Based Awards. As of the Covered Termination Date, unless otherwise settled in
accordance with the provisions of Section 3 of this Agreement and the plans and agreements referred to therein, a fully vested and non-forfeitable interest in any outstanding unvested equity-based awards,
and to the extent applicable, payable on the 60th day after the Covered Termination Date; provided that no such award that is subject to Code Section 409A will be paid on a date earlier than is provided in the applicable plan and award
agreement. 

  

	 	(iv)	 Severance Payment Based on Salary. An amount equal to two (2) times the sum of (i) the
Salary, and (ii) Executive’s target award under the EICP for the year in which the Covered Termination Date occurs, in a lump sum in cash on the 60th day after the Covered Termination Date. 

  
 1 

	 	(v)	 Severance Payment Based on Bonus. 

 

	 	(1)	 Current Performance Year. An amount equal to the product of (A) the Salary and (B) the
Target Bonus Percentage, with the product of (A) and (B) prorated based on the number of days Executive was employed during the bonus year in which Executive’s Covered Termination Date occurs, in a lump sum in cash on the 60th day after
the Covered Termination Date. 

  

	 	(2)	 Prior Performance Year. If a bonus is paid under the EICP after Executive’s Covered
Termination Date occurs for the immediately preceding calendar year, then Executive will be entitled to an amount equal to the product of (A) the Salary and (B) the Target Bonus Percentage (or, if greater, the actual amount of the bonus
determined under the EICP for such prior calendar year), in a lump sum in cash at the later of (i) the 60th day after the Covered Termination Date and (ii) the time such bonus is paid to other EICP participants. 

 

	 	(vi)	 Other Compensation. The Other Compensation payable or provided in the manner and time specified
in applicable documents governing such amounts. 

  

	 	(b)	 Waiver and Release. Notwithstanding any provision of this Agreement to the contrary, in order to
receive the severance benefits payable under any provision of Section 2(a)(ii), (iii), (iv) and (v) of this Agreement, Executive must first execute an appropriate waiver and release agreement in a form acceptable to the Company (a
currently acceptable form is attached hereto as Exhibit B (the “Waiver and Release”)), whereby Executive shall agree to release and waive, in return for such severance benefits, any claims that Executive may have
against the Company and the Employer and their respective Affiliates, directors, officers and other customary persons from any claim or liability arising out of or related to Executive’s employment with or termination of employment from the
Employer and any of its Affiliates (except for amounts to which Executive is legally entitled pursuant to employee benefit plans and rights to indemnification); provided, however, such Waiver and Release shall not release any claim or cause of
action by or on behalf of Executive for any payment or vested benefit that is due under either this Agreement or any employee benefit plan or program of the Company or the Employer until fully paid prior to the receipt thereof. Executive shall have
21 days (or 45 days, if applicable, as determined by the Company) after receipt of the Waiver and Release to consider and timely execute and return it to the Company. After return, Executive shall have an additional seven days in which Executive can
revoke the Waiver and Release; thereafter, the Waiver and Release shall be irrevocable. The Company or the Employer shall provide the Waiver and Release to Executive no later than five days after his Termination Date. If the Waiver and Release is
not timely executed and returned, or if it is revoked within the seven-day revocation period, no benefits shall be paid under this Agreement except those to which the Executive has a vested interest without
regard to Section 2(a) of this Agreement. 

  
 2 

	 	(c)	 Reduction to Avoid Parachute Taxes. Exhibit C hereto sets forth the manner of reduction to
be applied to avoid parachute taxes. 

 In no event shall the payments or benefits provided for in Sections 2(a)(i),
2(a)(iii), 2(a)(iv) and 2(a)(v) above that are not subject to Code Section 409A be paid later than March 15th of the calendar year immediately following the calendar year in which Executive’s Covered Termination Date occurs. 

 

	3.	 CHANGE IN CONTROL EQUITY-BASED
BENEFITS. If a Change in Control occurs, any benefits Executive may be entitled to with respect to any equity-based compensation shall be determined in accordance with the applicable plans and award agreements. In the event of any
conflict between the terms of any such plan or award agreement and Section 2(a)(iii) of this Agreement, the terms of such plan or award agreement shall control. 

 

	4.	 INTERNAL REVENUE CODE
SECTION 409A. 

  

	 	(a)	 Compliance. It is the intent of the parties that the provisions of this Agreement either comply
with Code Section 409A and the Treasury regulations and guidance issued thereunder or that one or more elements of compensation or benefits be exempt from Code Section 409A. Accordingly, the parties intend that this Agreement be
interpreted and operated in a manner consistent with such requirements in order to avoid the application of penalty taxes under Code Section 409A to the extent reasonably practicable. The Company and the Employer shall neither cause nor permit:
(i) any payment, benefit or consideration to be substituted for a benefit that is payable under this Agreement if such action would result in the failure of any amount that is subject to Code Section 409A to comply with the applicable
requirements of Code Section 409A; or (ii) any adjustments to any equity interest to be made in a manner that would result in the equity interest’s becoming subject to Code Section 409A unless, after such adjustment, the equity
interest is in compliance with the requirements of Code Section 409A to the extent applicable. A Covered Termination is an “involuntary separation from service” for purposes of Code Section 409A. 

 

	 	(b)	 Waiting Period for Specified Employees. Notwithstanding any provision of this Agreement to the
contrary, if Executive is a “Specified Employee” (as that term is defined in Code Section 409A) as of Executive’s Covered Termination Date, then any amounts or benefits which are payable under this Agreement upon Executive’s
“Separation from Service” (within the meaning of Code Section 409A), which are subject to the provisions of Code Section 409A and not otherwise excluded under Code Section 409A, and would otherwise be payable during the
first six-month period following such Separation from Service, shall be paid on the first business day that (i) is at least six months after the date after Executive’s Covered Termination Date or
(ii) follows Executive’s date of death, if earlier. 

  
 3 

	5.	 CONFIDENTIALITY AND NON-DISCLOSURE. 

  

	 	(a)	 Executive acknowledges that, pursuant to this Agreement, the Company and the Employer agree to provide
Executive with Confidential Information regarding the Company and the Employer and their respective businesses and have previously provided Executive other such Confidential Information. In return for this and other consideration provided under this
Agreement, Executive agrees that Executive will not, while employed by the Employer or any of its Affiliates and thereafter, disclose or make available to any other person or entity, or use for Executive’s own personal gain, any Confidential
Information, except for such disclosures as required in the performance of Executive’s duties hereunder as may otherwise be required by applicable law or legal process (in which case Executive shall notify the Company and the Employer of such
legal or judicial proceeding as soon as practicable following Executive’s receipt of notice of such a proceeding, and permit the Company and the Employer to seek to protect its interests and information). For purposes of this Agreement,
“Confidential Information” shall mean any and all information, data and knowledge that has been created, discovered, developed or otherwise become known to the Company, the Employer or any of their respective Affiliates or ventures or in
which property rights have been assigned or otherwise conveyed to the Company, the Employer or any of their respective Affiliates or ventures, which information, data or knowledge has commercial value in the business in which the Company, the
Employer or any of their respective affiliates is engaged, except such information, data or knowledge as is or becomes known to the public without Executive’s violation of any of the terms of this Section 5. By way of illustration, but not
limitation, Confidential Information includes business trade secrets, secrets concerning the Company’s and the Employer’s plans and strategies, nonpublic information concerning material market opportunities, technical trade secrets,
processes, formulas, know-how, improvements, discoveries, developments, designs, inventions, techniques, marketing plans, manuals, records of research, reports, memoranda, computer software, strategies,
forecasts, new products, unpublished financial information, projections, licenses, prices, costs, and employee, customer and supplier lists or parts thereof. 

  

	 	(b)	 Nothing in this Agreement shall prohibit or restrict Executive from lawfully (i) initiating communications
directly with, cooperating with, providing information to, causing information to be provided to, or otherwise assisting in an investigation by any governmental or regulatory agency, entity, or official(s) (collectively, “Governmental
Authorities”) regarding a possible violation of any law; (ii) responding to any inquiry or legal process directed to Executive individually from any such Governmental Authorities; (iii) testifying, participating or otherwise assisting
in an action or proceeding by any such Governmental Authorities relating to a possible violation of law; or (iv) making any other disclosures that are protected under the whistleblower provisions of any

  
 4 

	 	
applicable law. Additionally, pursuant to the federal Defend Trade Secrets Act of 2016, Executive shall not be held criminally or civilly liable under any federal or state trade secret law for
the disclosure of a trade secret that: (i) is made (A) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney; and (B) solely for the purpose of reporting or investigating a
suspected violation of law; or (ii) is made to Executive’s attorney in relation to a lawsuit for retaliation against Executive for reporting a suspected violation of law; or (iii) is made in a complaint or other document filed in a
lawsuit or other proceeding, if such filing is made under seal. This Agreement does not require Executive to obtain prior authorization from the Company before engaging in any conduct described in this paragraph, or to notify the Company that
Executive has engaged in any such conduct. 

  

	6.	 RETURN OF PROPERTY. Executive agrees that at the time of
Executive’s leaving employ with the Employer or any of its Affiliates, Executive will deliver to the Employer (and will not keep in his possession, recreate or deliver to anyone else) all Confidential Information as well as all other devices,
records, data, notes, reports, proposals, lists, correspondence, specifications, drawings, blueprints, sketches, materials, equipment, customer or client lists or information, or any other documents or property (including all reproductions of the
aforementioned items) belonging to the Company, the Employer or any of their respective Affiliates, regardless of whether such items were prepared by Executive. 

 

	7.	 NON-COMPETITION; NON-SOLICITATION. 

  

	 	(a)	 Executive agrees to the non-competition and non-solicitation provisions of this Section 7: (i) in consideration for the Confidential Information provided by the Company to Executive; and (ii) to protect the Confidential Information of the Company
disclosed or entrusted to Executive by the Company or created or developed by Executive for the Company, the business goodwill of the Company developed through the efforts of Executive and the business opportunities disclosed or entrusted to
Executive by the Company. Executive agrees that in the event that Executive fails to comply with any of the provisions of this Section 7, Executive will repay to the Company any payments received pursuant to this Agreement and no further
benefits will be payable to Executive under this Agreement. 

  

	 	(b)	 Executive agrees that, while employed by the Employer or any of its Affiliates and for 12 months following a
Covered Termination or any termination of employment by Executive, Executive shall not, without the prior written consent of the Company and the Employer, directly or indirectly, (i) carry on or engage in any Competing Business (as defined
below) in the Restricted Area (as defined below); and (ii) own, manage, operate, join, become an employee, partner, owner or member of (or an independent contractor to), control or participate in or loan money to, sell or lease equipment to or
sell or lease real property to any Person that engages in a Competing Business in the Restricted Area. 

  
 5 

	 	(c)	 Notwithstanding the restrictions contained in Section 7(b), Executive may own an aggregate of not more
than 1% of the outstanding capital stock or other equity security of any class of any corporation or other entity engaged in a Competing Business, if such capital stock or other equity security is listed on a national securities exchange or
regularly traded in the over-the-counter market by a member of a national securities exchange, without violating the provisions of Section 7(b);, provided that
Executive does not have the power, directly or indirectly, to control or direct the management or affairs of any such corporation or other entity and is not involved in the management of such corporation. 

 

	 	(d)	 Executive agrees that, while employed by the Employer or any of its Affiliates and for 12 months following a
Covered Termination or any voluntary termination of employment by Executive, Executive shall not, without the prior written consent of the Company and the Employer, directly or indirectly, (i) hire or induce, entice or solicit (or attempt to
induce, entice or solicit) any employee of the Company, the Employer or any of their respective Affiliates or ventures to leave the employment of the Company, the Employer or any of their respective Affiliates or ventures or (ii) solicit or
attempt to solicit the business of any customer or acquisition prospect of the Company, the Employer or any of their respective Affiliates or ventures with whom Executive had any actual contact while employed at the Employer. 

 

	 	(e)	 Executive acknowledges that these restrictive covenants under this Agreement, for which Executive received
valuable consideration from the Company and the Employer as provided in this Agreement, including, but not limited to the agreement of the Company and the Employer to provide Executive with Confidential Information are ancillary to otherwise
enforceable provisions of this Agreement, that the consideration provided by the Company and the Employer gives rise to the interest of each of the Company and the Employer in restraining Executive and that the restrictive covenants are designed to
enforce Executive’s consideration or obligations under this Agreement. Additionally, Executive acknowledges that these restrictive covenants contain limitations as to time and scope of activity to be restrained that are reasonable and do not

 In exchange for the payments and other benefits to be provided to me by the Company and the Employer pursuant to Section 2 of the Change in Control
Agreement (the “Separation Payment” and “Separation Benefits”), I hereby agree and state as follows: 
  

	1.	 I, individually and on behalf of my heirs, personal representatives, successors, and assigns, release, waive,

consideration received by me through this Release, any and all Released Claims that I may have against any Released Party, regardless of whether they actually exist, are expressly settled, compromised and waived. This Release includes matters
attributable to the sole or partial negligence (whether gross or simple) or other fault, including strict liability, of any Released Party. 

Notwithstanding the foregoing, I am not waiving any rights or claims that may arise after this Release is signed by me. Moreover, this Release

	4.	 I agree that I will refrain from any libel, slander, defamation or other disparaging comments about the
Company, the Employer, their respective affiliates, or any current or former officer, director or employee of the Company, the Employer or any of their respective affiliates. However, I understand that nothing in this Release prohibits me from
filing a charge with, or reporting possible violations of federal law or regulation to any governmental agency or entity, including, but not limited to, the U.S. Equal Opportunity Commission, the Department of Justice, the Securities and Exchange

	 	d.	 I acknowledge that I have received payment for all wages due at time of my employment termination, including
reimbursement for any and all business-related expenses. I further acknowledge that the Separation Payment and the Separation Benefits are consideration to which I am not otherwise entitled under any Company plan, program, or prior agreement.

  

	 	e.	 I certify that I have returned all property of the Company, the Employer and their respective affiliates,
including, but not limited to, keys, credit and fuel cards, computers, cell phones, and other electronic devices, files, lists, and documents of all kinds regardless of the medium in which they are maintained. 

 

	 	f.	 I have carefully read the contents of this Release and I understand its contents. I am executing this Release
voluntarily, knowingly, and without any duress or coercion. 

  

	6.	 I acknowledge that this Release shall not be construed as an admission by any of the Released Parties of any
liability whatsoever, or as an admission by any of the Released Parties of any violation of my rights or the rights of any other person, or any violation of any order, law, statute, duty or contract. 

 

	7.	 I agree that the terms and conditions of this Release are confidential and that I will not, directly or
indirectly, disclose the existence of or terms of this Release to anyone other than my attorney or tax advisor, except to the extent such disclosure may be required for accounting or tax reporting purposes or otherwise be required by law or
direction of a court. Nothing in this provision shall be construed to prohibit me from disclosing this Release to the Equal Employment Opportunity Commission in connection with any complaint or charge submitted to that agency. 

  
 B-3

portions shall remain in full force and effect.

the Employer, superseding any and all prior agreements, and that neither the Company nor the Employer has made any promise or offered any other agreement, except those expressed in this Release, to induce or persuade me to enter into this Release.

 EXHIBIT C 

Excise Tax Modified Cutback Provisions 

Anything in this Agreement to the contrary notwithstanding, in the event the Firm (as defined below) shall determine that Executive shall
become entitled to payments and/or benefits provided by this Agreement which would be subject to the excise tax imposed by Code Section 4999 (the “Payments”), the Firm shall determine whether to reduce any of the Payments to
the Reduced Amount (as defined below). The Payments shall be reduced to the Reduced Amount only if the Firm determines that Executive would have a greater Net After-Tax Receipt (as defined below) of aggregate
Payments if the Executive’s Payments were reduced to the Reduced Amount. If such a determination is not made by the Firm, Executive shall receive all Payments to which Executive is entitled under this Agreement. 

If the Firm determines that aggregate Payments should be reduced to the Reduced Amount, the Company shall promptly give Executive notice to
that effect and a copy of the detailed calculation thereof. All determinations made by the Firm under this Exhibit C shall be binding upon the Company and Executive absent manifest error and shall be made as soon as
reasonably practicable but in no event later than 15 business days of the receipt of notice from the Company that there has been a Payment, or such earlier time as is requested by the Company. For purposes of reducing the Payments to the Reduced
Amount, only amounts payable under this Agreement (and no other Payments) shall be reduced. The reduction of the amounts payable hereunder, if applicable, shall be made by reducing, in order, cash payments otherwise due under Sections 2(a)(iv),
2(a)(v)(1) and 2(a)(v)(2) of this Agreement, and then by reducing equity-based compensation otherwise due under Section 2(a)(iii) of this Agreement in chronological order with the most recent equity based compensation awards reduced first. 

As a result of the uncertainty in the application of Code Section 4999 at the time of the initial determination by the Firm hereunder, it
is possible that amounts will have been paid or distributed by the Company to or for the benefit of Executive pursuant to this Agreement which should not have been so paid or distributed (“Overpayment”) or that additional amounts
which will have not been paid or distributed by the Company to or for the benefit of Executive pursuant to this Agreement could have been so paid or distributed (“Underpayment”), in each case, consistent with the calculation of the
Reduced Amount hereunder. In the event that the Firm, based upon the assertion of a deficiency by the Internal Revenue Service against either the Company or Executive which the Firm believes has a high probability of success determines that an
Overpayment has been made, Executive shall pay any such Overpayment to the Company together with interest at the applicable federal rate provided for in Code Section 7872(f)(2); provided, however, that no amount shall be payable by
Executive to the Company if and to the extent such payment would not either reduce the amount on which Executive is subject to tax under Code Sections 1 and 4999 or generate a refund of such taxes. In the event that the Firm, based upon controlling
precedent or substantial authority, determines that an Underpayment has occurred, any such Underpayment shall be paid promptly (but in no event later than 60 days following the date on which the Underpayment is determined) by the Company to or for
the benefit of Executive together with interest at the applicable federal rate provided for in Code Section 7872(f)(2). 

  
 C-1 

 For purposes hereof, the following terms have the meanings set forth below: 

“Firm” shall mean an internationally recognized accounting or employee benefits consulting firm selected by
the Company with the input of Executive (but without Executive’s consent) and which shall not, during the one year preceding the date of its selection, have acted in any way on behalf of the Company or its affiliated companies. 

“Net After-Tax Receipt” shall mean the present value (as determined in
accordance with Code Sections 280G(b)(2)(A)(ii) and 280G(d)(4)) of a Payment net of all taxes imposed on Executive with respect thereto under Code Sections 1 and 4999 and under applicable state and local laws, determined by applying the highest
marginal rate under Code Section 1 and under state and local laws which applied to the Executive’s taxable income for the immediately preceding taxable year, or such other rate(s) as Executive certifies, in Executive’s sole
discretion, as likely to apply to Executive in the relevant tax year(s). 
 “Reduced Amount” shall mean the
greatest amount of Payments that can be paid that would not result in the imposition of the excise tax under Code Section 4999 if the Firm determines to reduce Payments pursuant to the first paragraph of this Exhibit C.
