Exhibit 4.6

Execution Version

MANAGEMENT SERVICES AGREEMENT

This MANAGEMENT SERVICES AGREEMENT (Agreement) entered into on October 22, 2012, between Seadrill UK Ltd.
(Company) and Seadrill Partners LLC (Customer) and became effective on the Effective Date (as hereinafter defined).

WHEREAS, Customer has the need for the services usually performed by a Chief Executive Officer; and

WHEREAS, Company is able to provide an individual to render those services;

NOW,
THEREFORE, in consideration of the mutual promises, conditions and agreements herein contained, the sufficiency of which is hereby acknowledged, Company and Customer hereby agree as follows:



|1. | ENGAGEMENT
|-- | ----------

Customer
hereby engages Company to provide the services usually performed by a Chief Executive Officer (the Services) through the assignment of an individual to perform these services (the Assignee). The Services will be provided on
an as-needed basis as determined by Customer. From the Effective Date (as defined in Section 5 below), Company will assign the individual named in Schedule A to this Agreement, unless and until: (a) the Assignee is replaced in accordance
with Section 2; or (b) this Agreement is terminated in accordance with Section 5.

Company and Customer agree
that the terms and conditions set forth in this Agreement shall control and govern the Services performed by Company for Customer. Services may be added or deleted from time to time by mutual agreement of the parties evidenced in a written amendment
signed by a duly authorized representative of each party.



|2. | REPLACEMENT OF THE ASSIGNEE
|-- | ---------------------------

Customer may elect to remove or replace the Assignee at any time for any reason upon written notice to Company. In the event such notice is served by Customer, or in the event that the Assignee is
unwilling or unable to perform the Services for any reason, Company shall use its reasonable efforts to identify and assign a replacement with suitable skills and experience to assume the performance of the Services. Any such replacement shall be
subject to the prior approval of Customer. Company shall use reasonable efforts to ensure that any replacement for the Assignee shall work alongside the Assignee who is to be replaced for a reasonable handover period. In the event that the Assignee
is replaced pursuant to the terms of this paragraph, this Agreement shall remain in effect and such replacement shall be deemed to be the Assignee for the purposes of this Agreement effective as of the date of assignment agreed by the parties.



---

|3. | FEES AND PAYMENT
|-- | ----------------

Customer shall reimburse Company for the Services on a quarterly basis in an amount equal to the Costs and Expenses (as hereinafter
defined) incurred by Company during such calendar quarter in providing the Services. In addition, Customer shall pay to the Company a equal to five percent (5%) of such Costs and Expenses management fee for such calendar quarter
(Management Fee). Within thirty (30) days of the execution of this Agreement, and thereafter within thirty (30) days of the end of each calendar quarter, Company shall provide a written statement to Customer specifying the
Costs and Expenses and Management Fee with respect to the provision of Services during that calendar quarter. Within sixty (60) days of the receipt of such written statement from Company, Customer shall pay Company the undisputed amount set
forth in such statement. All statements and payments shall be made in United States Dollars. It is acceptable that payments may be settled by non-cash means as agreed between the parties. All payments that are not made when due and payable will be
considered overdue and remain payable together with interest for late payment at an agreed interest rate, or if none is agreed, at a rate of one (1) percent above the LIBOR on the date the payment became due, compounded monthly.

The term Costs and Expenses shall mean all costs and expenses reasonably incurred by Company in connection with the provision
of the Services for such calendar quarter.

Company shall keep and maintain, in accordance with generally accepted accounting
principles in the United States as applied by Company, books of account and other records with respect to the Costs and Expenses and Management Fees charged by Company to Customer under this Agreement. Customer may audit, at its own expense and no
more frequently than annually, the relevant books and records of Company to ensure compliance with the terms of this Agreement. Any such audit shall be conducted during regular business hours at Companys offices and shall not interfere
unreasonably with Companys business activities.



|4. | RELATIONSHIP OF THE PARTIES
|-- | ---------------------------

Nothing in this Agreement shall be construed as an assumption by Company (a) of any obligation to increase the revenues or profits of Customer or otherwise to guarantee the success of Customers
operations; or (b) the delegation of any function or authority of Customer to Company, it being understood that Company will provide the Services but that all decisions with respect to Customer shall remain with the Board of Directors and
authorized officers of Customer.

This Agreement constitutes a contract for the provision of services only and not a contract
of employment. Company shall remain solely and exclusively responsible for the payment of all remuneration and the provision of all benefits to the Assignee.



|5. | EFFECTIVE DATE, TERM AND TERMINATION
|-- | ------------------------------------

This Agreement shall be effective from June 29, 2012 (Effective Date).

Termination is without prejudice to accrued rights and obligations.
Upon termination, Company shall issue a final invoice to Customer, setting forth all Costs and Expenses and Management Fees incurred through the effective date of termination.



|6. | CONFIDENTIAL INFORMATION
|-- | ------------------------

Customer shall have the sole and exclusive right, title and interest to all confidential information generated as a result of
Companys provision of Services to Customer. In the case of confidential information acquired by the Assignee from third parties that relates to the provision of Services, the rights of Customer shall be subject to the terms of the agreements
with such third parties under which the Assignee acquired such confidential information.

loss of profits or business interruption, howsoever caused.

party shall be liable for any delay or non-performance of its obligations hereunder due to governmental regulation, labour disputes, hostile action, weather, peril of the sea, fire, acts of God, or any other causes beyond such partys
reasonable control (any and all of which causes are referred to herein as force majeure). If performance is so delayed or prevented for more than ninety (90) days, either party may immediately terminate the Agreement by written
notice. Force majeure shall not, however, excuse payment by Customer for Costs and Expenses and Management Fees accrued prior to such termination.



|9. | ENTIRE AGREEMENT
|-- | ----------------

This
Agreement constitutes the entire agreement between the parties relating to the Services, and no addition to or modification of any provision herein shall be effective unless made in writing and signed by duly authorized representatives of both
parties.



|10. | GOVERNING LAW AND ARBITRATION

This Agreement and any contractual or non-contractual obligations arising out of or in connection with it are governed by and shall be construed in accordance with, English law.
