#### Transocean Ltd.

#### Registration Statement on Form S-8
We have acted as special Swiss counsel to Transocean Ltd., a company limited by shares incorporated under the laws of Switzerland (the **Company**), in connection with the Registration Statement on Form S-8 (the **Registration Statement**) to be filed with the United States Securities and Exchange Commission (the **SEC**) on the date hereof under the Securities Act of 1933, as amended (the **Act**), with respect to the registration of an additional 16,000,000 registered shares of the Company, each with a nominal value of USD 0.10, that may be delivered pursuant to the Plan (as defined below).

As such counsel, we have been requested to give our opinion as to certain legal matters under Swiss law.

Capitalized terms used herein shall have the meaning attributed to them in the Documents unless otherwise defined herein. The Company's registered shares, each with a nominal value of USD 0.10, are referred to herein as **Registered Shares**.

&nbsp;&nbsp;&nbsp;&nbsp;I. Basis of Opinion

This opinion is confined to and given on the basis of the laws of Switzerland in force at the date hereof as currently applied by the Swiss courts. In the absence of explicit statutory law, we base our opinion solely on our independent professional judgment. This opinion is also confined to the matters stated herein and is not to be read as extending, by implication or otherwise, to any document referred to in the Documents (other than listed below) or any other matter.

For purposes of this opinion, we have not conducted any due diligence or similar investigation as to factual circumstances which are or may be referred to in the Documents, and we express no opinion as to the accuracy of representations and warranties of facts set out in the Documents or the factual background assumed therein.

For the purpose of giving this opinion, we have only reviewed originals or copies of the following documents (collectively the **Documents**):

&nbsp;&nbsp;&nbsp;&nbsp;(a) An electronic copy of the resolution passed by the shareholders of the Company (the **Shareholder Resolution**) at the Company's annual general meeting held on May 30, 2025

------

(the **AGM**), as reflected in the minutes of such meeting, dated May 30, 2025, regarding the approval by the Company's shareholders of, among other things, the reserve of an additional 16,000,000 Registered Shares in the aggregate amount of Registered Shares available for issuance pursuant to the Amended and Restated Transocean Ltd. 2015 Long-Term Incentive Plan (the **Plan**);

&nbsp;&nbsp;&nbsp;&nbsp;(b) an electronic copy of the resolutions of the Company's board of directors adopted by written consent as of March 21, 2025 (the **Board Resolutions**, and together with the Shareholders' Resolution, the **Resolutions**), including, among other things, a resolution approving the amendment and the restatement of the Plan, and a resolution to reserve up to 16,000,000 Registered Shares in the aggregate amount of Registered Shares available pursuant to the Plan;

&nbsp;&nbsp;&nbsp;&nbsp;(c) an electronic copy of the Plan;

&nbsp;&nbsp;&nbsp;&nbsp;(d) an electronic copy of the certified articles of association (Statuten) of the Company in their version as of May 30, 2025, certified by the Commercial Register of the Canton of Zug on July 28, 2025 (the **Articles of Association**);

&nbsp;&nbsp;&nbsp;&nbsp;(e) an electronic copy of the Organizational Regulations (*Organisationsreglement*) of the Company, dated as of May 30, 2025 (the **Organizational Regulations**); and

&nbsp;&nbsp;&nbsp;&nbsp;(f) an electronic copy of the certified excerpt from the Commercial Register of the Canton of Zug, Switzerland, for the Company, dated July 28, 2025 (the **Excerpt**).

No documents have been reviewed by us in connection with this opinion other than those listed above. Accordingly, we shall limit our opinion to the Documents and their legal implications under Swiss law.

In this opinion, Swiss legal concepts are expressed in English terms and not in their original language. These concepts may not be identical to the concepts described by the same English terms as they exist under the laws of other jurisdictions.

&nbsp;&nbsp;&nbsp;&nbsp;II. Assumptions

In rendering the opinion below, we have assumed the following:

&nbsp;&nbsp;&nbsp;&nbsp;(b) all documents produced to us as originals and the originals of all documents produced to us as copies were duly executed and certified, as applicable, by the individuals purported to have executed or certified, as the case may be, such documents, and any electronic signatures on any such document have been affixed thereto by the individual to whom such electronic signature belongs and such individual has saved and submitted such document as so electronically signed in such a manner so as to prevent removal or other alteration of such signature;

------

&nbsp;&nbsp;&nbsp;&nbsp;(c) all factual information contained in, or material statements given in connection with, the Documents are true and accurate;

&nbsp;&nbsp;&nbsp;&nbsp;(d) the filing of the Registration Statement with the SEC has been authorized by all necessary actions under all applicable laws;

&nbsp;&nbsp;&nbsp;&nbsp;(e) the Registration Statement has been filed by the Company with the SEC;

&nbsp;&nbsp;&nbsp;&nbsp;(f) any Registered Shares issued out of the conditional share capital of the Company pursuant to Article 6 of the Articles of Association (the **Conditional Share Capital**) will be listed on the New York Stock Exchange in accordance with applicable laws and regulations;

&nbsp;&nbsp;&nbsp;&nbsp;(h) the exercise notice with respect to Registered Shares issued out of Conditional Share Capital will be duly delivered in accordance with Swiss law and the Plan;

&nbsp;&nbsp;&nbsp;&nbsp;(i) to the extent the Company issues Registered Shares out of Conditional Share Capital, the performance of the contributions in money shall be made at a banking institution subject to the Federal Law of November 8, 1934, Relating to Banks and Savings Banks, as amended, or, in case of performance of the contributions by way of set-off, in accordance with the applicable provisions of the Swiss Code of Obligations;

&nbsp;&nbsp;&nbsp;&nbsp;(j) no Registered Shares have been issued out of the Conditional Share Capital since the date of the Articles of Association;

&nbsp;&nbsp;&nbsp;&nbsp;2. The Company's share capital registered in the Commercial Register of the Canton of Zug amounts to USD 120,400,968.10, divided into 1,204,009,681 Registered Shares. Such

------

Registered Shares have been validly issued, fully paid up to their nominal value and are non-assessable.

&nbsp;&nbsp;&nbsp;&nbsp;3. The Registered Shares that may be issued from the Conditional Share Capital, if and when such Registered Shares are issued pursuant to the Plan, and after the nominal amount for such Registered Shares has been paid-in in cash or by way of set-off, will be validly issued, fully paid and non-assessable.

&nbsp;&nbsp;&nbsp;&nbsp;IV. Qualifications

The above opinions are subject to the following qualifications:

&nbsp;&nbsp;&nbsp;&nbsp;(a) The lawyers of our firm are members of the Zurich bar and do not hold themselves out to be experts in any laws other than the laws of Switzerland. Accordingly, we are opining herein as to Swiss law only and we express no opinion with respect to the applicability thereto, or the effect thereon, of the laws of any other jurisdiction.

&nbsp;&nbsp;&nbsp;&nbsp;(b) We note that, under Swiss law, shares issued out of Conditional Share Capital cannot be paid-in by way of contribution in kind.

&nbsp;&nbsp;&nbsp;&nbsp;(c) The exercise of voting rights and rights related thereto with respect to any Registered Shares is only permissible after registration in the Company's share register as a shareholder with voting rights in accordance with the provisions of, and subject to the limitations provided in, the Articles of Association.

&nbsp;&nbsp;&nbsp;&nbsp;(d) We express no opinion as to any commercial, accounting, tax, calculating, auditing or other non-legal matter.

&nbsp;&nbsp;&nbsp;&nbsp;(e) We have not investigated or verified the truth or accuracy of the information contained in the Registration Statement, nor have we been responsible for ensuring that no material information has been omitted from it.

&nbsp;&nbsp;&nbsp;&nbsp;(f) Any issuance of the Registered Shares out of Conditional Share Capital must be confirmed by the auditor of the Company, and amended Articles of Association of the Company reflecting the issuance of Registered Shares from Conditional Share Capital, together with said confirmation by the Company's auditor, must be filed with the competent commercial register no later than three months after the end of the Company's fiscal year.

__________

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act.
