Exhibit 10.1

RETIREMENT AND NON-EXECUTIVE CHAIRMAN AGREEMENT

This Retirement and Non-Executive Chairman Agreement (the “Agreement”) is dated April 17, 2012 (the “Effective Date”), by and between Tidewater Inc., a Delaware corporation (the “Company”) and Dean E. Taylor (the “Executive”).

WHEREAS, Executive has advised the Company of his desire to retire as the Company’s President and Chief Executive Officer; and

WHEREAS, the Executive is currently the Chairman of the Board of Directors of the Company, and the Board of Directors desires to retain the services of the Executive as Non-Executive Chairman;

NOW THEREFORE, in consideration of the mutual promises herein contained and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the parties hereto agree as follows:

ARTICLE I

EMPLOYMENT TERM

1.1 Employment. Executive agrees to continue to serve as an employee and the President and Chief Executive Officer of the Company on a full-time basis, such service to continue until May 31, 2012 (the “Retirement Date”).

1.2 Devotion to Responsibilities. Until such time as he is no longer the President and Chief Executive Officer of the Company, Executive shall carry on his ordinary and customary duties. In addition, the Executive shall assist the Company in effecting an orderly transition of his responsibilities to his successor and perform such other duties as may be reasonably requested by the Board of Directors.

ARTICLE II

NON-EXECUTIVE CHAIRMAN OF THE BOARD

2.1 Engagement and Term. The Company hereby engages the Executive and the Executive hereby accepts engagement as Non-Executive Chairman, with such engagement to begin as of the Retirement Date and continuing through December 31, 2013 (the “Term”). The date the Term ends is referred to in this Agreement as the “Termination Date.”

2.2 Scope of Services and Duties. During the Term, the Executive agrees to be reasonably available, either in person, by telephone, or via electronic mail to consult, advise, and assist in connection with such matters as the Company may reasonably request and as are within his area of expertise and prior experience, including but not limited to: (a) presiding at all meetings of the Board of Directors; (b) working to assure that the Board of Directors functions effectively and meets its obligations and responsibilities; (c) coordinating with the Chief Executive Officer and the Lead Independent Director in the setting of the agenda and the preparation and distribution of information packages and related matters for meetings of the Board of Directors; (d) with the Lead Director, serving as liaison between management and the Board of Directors; (e) mentoring the Company’s Chief Executive Officer and introducing the

Chief Executive Officer to key customers and contacts; (f) serving, at the request of the Chief Executive Officer, as a liaison with customers, government officials and stockholders on behalf of the Company; and (g) performing such other duties as may be fixed by the Board of Directors from time to time. The Executive agrees to devote such time as is reasonably necessary to effectively assist the Company with regard to these matters, but no more than 20% of such time as Executive previously devoted to his responsibilities as an employee of the Company.

2.3 Independent Contractor Status. It is the intention of the parties to establish, during the Term, an independent contractor relationship and not an employer-employee relationship, partnership, or joint venture. During the Term, the Executive shall not be deemed employed by the Company for purposes of any federal or state withholding taxes, and the Company shall not be responsible for or required to withhold any such taxes for or on behalf of the Executive. Unless otherwise specifically agreed upon in writing, the Executive shall not have any authority during the Term to act as the Company’s agent for any purposes, or to otherwise incur any liability or obligation in the name or on behalf of the Company other than in his position as the Non-Executive Chairman of the Board.

2.4 Compliance with Company Policies. The Executive agrees that, during the Term, he will continue to comply with all company policies to the extent relevant to his activities, including but not limited to: (a) the Code of Business Conduct and Ethics; and (b) the Policy Statement on Insider Trading, which prohibits, among other things, trading in the Company’s securities while in possession of material nonpublic information.

2.5 Date of Separation from Service. The parties agree that the services to be provided during the Term pursuant to this Agreement are distinct from the services the Executive provided as an employee of the Company. Nevertheless, the parties agree that the level of services expected to be provided by the Executive during the Term shall not exceed the level of services permitted under Treasury Regulations § 1.409A-1(h)(1)(i) under which the Executive is presumed to have had a “Separation from Service” and shall not affect the date of the Executive’s “Separation from Service” from the Company, as such term is defined in the regulations under Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”). The Retirement Date shall be the Executive’s date of Separation from Service.

ARTICLE III

COMPENSATION AND BENEFITS

3.1 Pre-Retirement Compensation and Benefits. Executive’s salary and benefits shall remain unchanged through the Retirement Date. In particular, Executive shall continue to be entitled to receive through the Retirement Date: (a) base salary at the annual rate of $695,250, which was his base salary as of the Effective Date; (b) his annual bonus for the 2012 fiscal year, which the Compensation Committee has determined to be an aggregate award of $540,500 pursuant to the terms of the Company’s annual incentive plan, and which shall be paid out at such time as annual cash bonuses are paid to other senior executives and in accordance with the terms and conditions of the annual bonus plan (including, if applicable, any adjustment based on the Executive’s bonus bank balance); and (c) the same pension, health care and perquisites benefits through the Retirement Date that he was paid at the time that he entered into this Agreement.

2

3.2 Pro-Rata Bonus Payment. The Company will pay to the Executive or his legal representatives a pro rata Bonus (the “Pro Rata Bonus”) for the 2013 fiscal year, which shall be paid out at such time as annual cash bonuses are paid to other senior executives of the Company and in accordance with the terms and conditions of the annual bonus plan. The Executive’s annual incentive target shall remain unchanged (120% of salary) and the amount of the Pro Rata Bonus shall be determined by multiplying: (a) the annual bonus the Executive would have received pursuant to the terms of the annual bonus plan as determined by the Compensation Committee had he remained employed by the Company through the end of the 2013 fiscal year; by (b) 2/12, representing the number of calendar months during the 2013 fiscal year that the Executive was an employee.

3.3 Supplemental Executive Retirement Plan. The Company acknowledges that the Executive is a participant in the Tidewater, Inc. Supplemental Executive Retirement Plan, as amended (the “SERP”), and that he will receive any benefits due under the SERP in accordance with the terms and conditions of the SERP. Based on the terms of this Agreement and the terms of the SERP, the parties anticipate that the SERP payment will be made on December 1, 2012.

3.4 Compensation and Benefits During the Term.

(a) As a non-employee member of the Company’s Board of Directors, following the Retirement Date the Executive shall be entitled to receive the compensation payable to the Company’s non-employee directors, which compensation shall be prorated during the first fiscal year from the Retirement Date. In addition, during the Term the Executive shall receive an additional Non-Executive Chairman annual retainer of $150,000, which retainer shall be prorated for partial year service.

(b) During the Term, the Executive shall be entitled to receive prompt reimbursement for all reasonable and necessary expenses incurred by the Executive in performing non-executive chairman services, provided that such expenses are incurred under this Agreement and accounted for in accordance with policies and procedures established by the Company.

(c) During the Term, the Company shall provide the Executive with dedicated on-site office space in New Orleans, periodic guest office space in Houston, as needed, continued secretarial support (which shall be provided by Executive’s secretarial assistant as of the Effective Date, or, a mutually agreeable individual, who may also provide services to other Company personnel), a cell phone, a computer, and a Company email address, with appropriate linkage to the Company’s communications or intranet network, with any charges incurred by the Executive related to such items to be paid or reimbursed by the Company to the extent used for Company business. Additionally, the Company shall pay dues and expenses related to the Executive’s membership at Lakeside Country Club and dues and expenses related to the Executive’s membership at one additional luncheon club.

(d) In the event that during the Term, the Executive is required to travel on Company business, he shall be entitled to travel using first class air travel arrangements at the Company’s expense. Additionally, during the Term, the Chief Executive Officer may, in his sole discretion, permit the Executive to use the Company’s aircraft.

3.5 Indemnification. To the maximum extent provided by law, the Company shall indemnify and hold Executive harmless from all claims, actions, damages or losses relating in any way to the Executive’s provision of services hereunder. The benefits provided herein are in addition to (i) any rights to indemnification and defense, including any right to advancement of legal fees and expenses, as are provided to the Executive pursuant to the Company’s certificate of incorporation and bylaws, and under Delaware General Corporation Law, and (ii) Executive’s rights pursuant to that certain Indemnification Agreement between the Company and the Executive dated December 15, 2009 (the “Indemnification Agreement”).

3.6 Post-Retirement Insurance.

Subject to any eligibility or participation requirements as may be established pursuant to the terms thereof, Executive shall be entitled to continue individual or family medical insurance coverage pursuant to terms of the Company’s retiree medical plan or Section 4980B of the Internal Revenue Code of 1986, as amended (“COBRA”). The premium for either option will be paid by the Company through December 31, 2013 and treated as taxable compensation to the Executive. Notwithstanding, if COBRA coverage is elected, the premium will be paid only through the maximum continuation period permitted under the law. Further, the Company’s premium payment will apply only to the continuation of medical coverage.

After the period during which the Executive would be entitled to COBRA continuation coverage, the payment or reimbursement of the applicable premium, or the payment of taxable medical benefits, shall comply with the nonqualified deferred compensation rules of Section 409A. Such payments or reimbursements will be deemed paid as of the first of each month and: (a) the amount of benefits or reimbursements provided during one calendar year shall not affect the amount of benefits or reimbursements to be provided in any other calendar year; (b) the reimbursement of any eligible expense shall be made no later than the last day of the calendar year following the year in which the expense was incurred; and (c) the right to reimbursement or benefits hereunder is not subject to liquidation or exchange for another benefit.

3.7 Options and Restricted Stock.

(a) Any outstanding stock options held by the Executive as of the Effective Date that are not vested as of the Retirement Date shall continue to vest during the Term, but in other respects shall remain subject to any other terms of the applicable incentive agreement, except as otherwise provided herein. On December 31, 2013 or earlier upon the Executive’s termination of service due to death or disability or involuntary termination of the Executive’s service as Non-Executive Chairman by the Company prior to December 31, 2013, all such unvested stock options previously granted to the Executive shall vest. Each of the Executive’s vested but unexercised stock options must be exercised by the second anniversary of the Termination Date or, if earlier, within ten years from the applicable date of grant.

(b) Any outstanding shares of restricted stock held by the Executive as of the Effective Date for which vesting is solely contingent upon continued service and that are not vested as of the Retirement Date shall continue to vest during the Term but in other respects shall remain subject to any other terms of the applicable incentive agreement, except as otherwise provided herein. On December 31, 2013 or earlier upon the Executive’s termination of service

4

due to death or disability or involuntary termination of the Executive’s service as Non-Executive Chairman by the Company prior to December 31, 2013, all such unvested shares of restricted stock previously granted to the Executive for which vesting is solely contingent upon continued service shall vest.

(c) With respect to any outstanding shares of restricted stock held by the Executive as of the Effective Date for which vesting is contingent upon the achievement of performance conditions (“Performance-Based Restricted Stock”) and that are not vested as of the Retirement Date, the terms and conditions of the incentive agreements under which such shares of Performance-Based Restricted Stock were granted shall, subject to the conditions outlined in this Section 3.7(c) and Article IV of this Agreement, be revised to: (i) permit the Executive’s service as Non-Executive Chairman during the Term to fulfill the continued service requirement under the incentive agreements; and (ii) eliminate the continued service requirement under the incentive agreements beyond December 31, 2013, or earlier upon the Executive’s termination of service due to death or disability or involuntary termination of the Executive’s service as Non-Executive Chairman prior to December 31, 2013. At the end of the performance period applicable to any of the Performance-Based Restricted Stock, to the extent the performance goals are achieved and such Performance-Based Restricted Stock vests, then the Executive shall receive the vested shares, provided that the Executive: (i) serves as Non-Executive Chairman continuously through December 31, 2013 (except as otherwise provided above in the case of earlier termination due to death or disability, or involuntary termination by the Company); and (ii) complies with Article IV of this Agreement during the applicable performance period.

(d) To the extent this Section 3.7 changes the terms of stock options or restricted stock held by the Executive, this Section 3.7 shall be deemed to be an amendment to the incentive agreements between the Company and the Executive setting forth the terms of such incentives and shall form part of each such agreement. For purposes of clarification, the outstanding awards referenced in this Section 3.7 include the awards granted to the Executive on March 14, 2012.

ARTICLE IV

NONDISCLOSURE, NONSOLICITATION OF EXECUTIVES,

PROPRIETARY RIGHTS AND COMPETITION

4.1 Certain Definitions. For purposes of this Agreement, the following terms shall have the following meanings:

(a) “Confidential Information” means confidential and proprietary information, knowledge, or data of any nature and in any form (including information that is electronically transmitted or stored on any form of magnetic or electronic storage media) of the past, current, or prospective business or operations of the Company, its consolidated subsidiaries, and any joint ventures in which the Company participates (the “Tidewater Group”), that is not publicly known, whether or not marked confidential, including without limitation information relating to any: (i) services, projects or jobs; (ii) estimating or bidding procedures; (iii) bidding strategies; (iv) present and future business plans, actual or potential business acquisitions or joint ventures, capital expenditure projects, and cost summaries; (v) trade secrets; (vi) marketing data, strategies, or techniques; (vii) financial reports, budgets, projections, and cost analyses; (viii)

5

pricing information, codes, and analyses; (ix) employee lists; (x) customer records, customer lists, and customer source lists; (xi) confidential filings with any government agency; and (xii) internal notes and memoranda relating to any of the foregoing, provided that Confidential Information shall not include any information, knowledge, or data that is now, or hereafter becomes, known to the public (other than by breach of this Agreement by the Executive or breach by any other party of a confidentiality obligation owed to the Company).

(b) “Restricted Business” means the businesses of: (i) providing vessel services for the offshore oil and gas, marine construction, and LNG terminal support; and (ii) vessel construction and repair.

4.2 Nondisclosure of Confidential Information. The Executive shall hold in a fiduciary capacity and for the benefit of the Company all Confidential Information which shall have been obtained by the Executive during the tenure of Executive’s employment or service as a director of the Company (whether prior to or after the date of this Agreement) and shall use such Confidential Information solely in the good faith performance of his duties for the Company. Until the second anniversary of the Termination Date, the Executive agrees: (a) not to communicate or make available to any person or entity (other than the Company) any such Confidential Information, except upon the prior written authorization of the Company or as may be required by law or legal process; and (b) to deliver promptly to the Company upon its written request any Confidential Information in his possession. In the event that the provisions of any applicable law or the order of any court would require the Executive to disclose or otherwise make available any Confidential Information to a governmental authority or to any other third party, the Executive shall give the Company, unless it is unlawful to do so, prompt prior written notice of such required disclosure and, and if possible given the terms of any production order of the judicial governmental or administrative body, an opportunity to contest the requirement of such disclosure or apply for a protective order with respect to such Confidential Information by appropriate proceedings. This provision shall not limit in any way the Executive’s continued fiduciary duties owed to the Company and its stockholders while he remains a director of the Company.

4.3 Limited Covenant Not to Compete. The Executive agrees that from the Effective Date until May 31, 2015 (the end of the latest performance period applicable to the Executive’s Performance-Based Restricted Stock) (the “Restricted Period”), the Executive agrees that within any jurisdiction specified in Appendix A in which any member of the Tidewater Group carries on the Restricted Business, so long as any member of the Tidewater Group carries on a like line of business therein (collectively, the “Subject Areas”), the Executive will restrict his activities during the Restricted Period as follows:

(a) The Executive will not, directly or indirectly, for himself or others or in association with any other person, own, manage, operate, control, be employed in an executive, managerial, or supervisory capacity by, or otherwise engage or participate in, or allow his skill, knowledge, experience or reputation to be used in connection with, the ownership, management, operation, or control of any company or other business enterprise engaged in the Restricted Business within any of the Subject Areas; provided, however, that nothing contained herein shall prohibit the Executive from making passive investments as long as the Executive does not beneficially own more than 1% of the equity interests of a publicly-traded business enterprise

6

engaged in the Restricted Business within any of the Subject Areas. For purposes of this paragraph, “beneficially own” shall have the same meaning ascribed to that term in Rule 13d-3 under the Securities Exchange Act of 1934.

(b) The Executive will not, directly or indirectly, for himself or others or in association with any other person, solicit any customer of the Restricted Business or of any member of the Tidewater Group, or otherwise interfere, induce, or attempt to induce any customer, supplier, licensee, or business relation of the Tidewater Group for the purpose of soliciting, diverting, interfering, or enticing away the business of such customer, supplier, licensee, or business relation, or otherwise disrupting any previously-established relationship existing between such customer, supplier, licensee, or business relation and the Tidewater Group.

4.4 Non-solicitation. The Executive agrees that, during the Restricted Period, he will not, directly or indirectly, for himself or others or in association with any other person, make contact with any of the employees or independent contractors of the Tidewater Group for the purpose of soliciting such employee for hire, whether as an employee or independent contractor, or for the purpose of inducing such persons to leave the employ of the Tidewater Group or cease providing services to the Tidewater Group, or otherwise to disrupt the relationship of such persons with the Tidewater Group. In addition, the Executive will not hire, on behalf of himself or any company engaged in the Restricted Business, any employee of the Tidewater Group, whether or not such engagement is solicited by the Executive. The provisions of this Section 4.4 shall automatically expire without any requirement of notice or other communication between the parties on the Termination Date.

4.5 Proprietary Rights.

(a) The Executive agrees to and hereby does assign to the Company all his right, title, and interest in and to all inventions, business plans, work models, or procedures, whether or not patentable, which are made or conceived solely or jointly by him:

(i) at any time during the term of his employment with the Company or during the Term, or

(ii) with the use of materials of the Company.

(b) The Executive agrees that, to a reasonable extent and through the Termination Date, he will communicate to the Company or its representatives all facts known to him about such proprietary information, sign all necessary instruments, make all necessary oaths, and generally, at the Company’s expense, do everything reasonably practicable (without expense to the Executive) to aid the Company in obtaining and enforcing proper legal protection for all such matters in all countries and in vesting title to such proprietary information in the Company. At the Company’s request (during or after the term of this Agreement) and expense, the Executive will promptly execute a specific assignment of title to the Company, and perform any other acts reasonably necessary to implement the foregoing assignment.

4.6 Other Remedies. Executive acknowledges that a breach or threatened breach by Executive of Section 4.2, 4.3, 4.4, or 4.5 would cause immediate and irreparable harm to the Company not fully compensable by money damages or the exact amount of which would be

7

difficult to ascertain, and therefore the Company will not have an adequate monetary remedy at law. Accordingly, Executive agrees that, in the event of a breach or threatened breach by Executive of the provisions of Section 4.2, 4.3, 4.4, or 4.5, the Company shall have the right upon the occurrence of any such breach or threatened breach to cancel the continued vesting of the stock options, restricted stock and Performance-Based Restricted Stock provided for in Section 3.7, the unpaid Pro-Rata Bonus provided for in Section 3.2 and any unpaid salary, bonus, or commissions otherwise outstanding at the time of such breach or threatened breach. In particular, Executive acknowledges that the payments and benefits provided hereunder are conditioned upon Executive fulfilling any noncompetition and nondisclosure agreements and covenants contained in this Article IV. In the event Executive shall at any time breach this Article IV, the Company may suspend or eliminate payments under Article III during the period of such breach, including the continued vesting of the stock options, restricted stock and Performance-Based Restricted Stock provided for in Section 3.7. Executive acknowledges that any such suspension or elimination of payments would be an exercise of the Company’s right to suspend or terminate its performance hereunder upon Executive’s breach of this Agreement; such suspension or elimination of payments would not constitute, and should not be characterized as, the imposition of liquidated damages. Nothing contained herein shall be deemed to impair the Executive’s right to indemnification provided to the Executive pursuant to the Company’s certificate of incorporation, bylaws, or Delaware General Corporation Law, or pursuant to the Indemnification Agreement.

4.7 Executive’s Understanding of this Article. Executive acknowledges that the definition of Restricted Business, as well as the geographic and temporal scope of the covenants contained in Article IV are the result of arm’s-length bargaining and are fair and reasonable in light of: (a) the importance of the functions performed by Executive; (b) the nature and wide geographic scope of the operations of the Company and its subsidiaries; and (c) Executive’s level of control over and contact with the business and operations of the Tidewater Group.

ARTICLE V WAIVERS AND RIGHT OF REVOCATION

5.1 Waiver and Release by Executive.

Executive further acknowledges that he has read and fully understands each paragraph of this Agreement, that he was advised in writing by the Company to consult with an attorney prior to executing this Agreement, and that he has availed himself of legal or other counsel to the full extent that he desires. Executive also agrees and acknowledges that the consideration provided under this Agreement is in addition to any other payments, benefits, or other things of value to which he is entitled, including, but not limited to, payment of accrued vacation, rights under benefit plans of the Company (including, but not limited to, any earned but deferred amounts or rights under the Company’s Certificate of Incorporation, or bylaws as in effect as of the date of this Agreement and that he would not be entitled to any of the consideration provided under this Agreement in the absence of his execution and acceptance of this Agreement.

The parties acknowledge and agree that Tidewater is a company with extensive worldwide and offshore operations and it is the parties intent that the noncompetition covenant be given as broad a geographic effect as is lawful. Accordingly, in addition to the foregoing specified locations, it is the parties intent that the noncompetition covenant set forth in the Agreement be given effect throughout the United States and worldwide, to the extent that the Executive would seek to provide services similar to those provided to Tidewater to a company in competition with Tidewater in any of the jurisdictions in which it operates. To the extent that a court of relevant jurisdiction determines the geographic scope set forth herein to be overbroad, the parties hereby consent to such modification as the court may order such that the broadest possible geographic footprint of the noncompetition covenant is enforceable.
