undertakings the Registrant made in Item 17 of the Registration Statement to update and supplement the Registration Statement and the prospectus included therein to, among other things, include the information contained in our Annual Report on Form <FONT
STYLE="white-space:nowrap">10-K</FONT> for the year ended December&nbsp;31, 2018 (the &#147;Annual Report on Form <FONT STYLE="white-space:nowrap">10-K&#148;)</FONT> which was filed with the Securities and Exchange Commission (the &#147;SEC&#148;)
on February 28, 2019. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Registration Statement was originally declared effective by the SEC on November&nbsp;15, 2018. The Registration
Statement relates to the issuance by Tidewater of up to 3,434,934 shares of Tidewater common stock, par value $0.001 per share (the &#147;Common Stock&#148;), upon the exercise of certain outstanding warrants (the &#147;GLF Warrants&#148;). The GLF
Warrants, originally issued by GulfMark Offshore, Inc. (&#147;GulfMark&#148;), were assumed by Tidewater as a result of the business combination between Tidewater and GulfMark that was consummated on November&nbsp;15, 2018 (the &#147;business
combination&#148; and the consummation of such business combination, the &#147;closing&#148;). The business combination was effected pursuant to the terms and conditions of an Agreement and Plan of Merger, dated as of July&nbsp;15, 2018, by and
between Tidewater and GulfMark (the &#147;merger agreement&#148;). </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Pursuant to the terms of the merger agreement and the applicable GLF
Warrant Agreement (as defined below), each GLF Warrant that was outstanding immediately prior to the closing was automatically converted into a warrant exercisable for 1.100 of a fully paid, validly-issued and nonassessable share of Common Stock
(the &#147;exchange ratio&#148;), the same merger consideration paid in the business combination to holders of GulfMark&#146;s common stock, upon payment to Tidewater of the applicable exercise price and subject to the other terms and conditions of
the applicable GLF Warrant Agreement, including cash paid in lieu of any fractional share. There are two series of GLF Warrants: GLF Jones Act Warrants, which may be exercised at any time until November&nbsp;14, 2042 for an exercise price of $0.01
per share, and GLF Equity Warrants, which may be exercised at any time until November&nbsp;14, 2024 for an exercise price of $100.00 per share. Each series of GLF Warrants is subject to a warrant agreement with substantially the same terms and
conditions that applied to such warrant prior to the closing, as assumed and amended by Tidewater effective upon the closing. Although all of the GLF Warrants are immediately exercisable, the exercise of any GLF Warrants is subject to, among other
things, the limitations on foreign ownership as set forth in Tidewater&#146;s Amended and Restated Certificate of Incorporation (the &#147;Tidewater charter&#148;) that are intended to comply with the Merchant Marine Act of 1920 and the Shipping
Act, 1916, as amended, and the rules and regulations promulgated thereunder (collectively, the &#147;Jones Act&#148;). </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">As a result of the
business combination and pursuant to the GLF Warrant Agreements, Tidewater will issue shares of Common Stock to the holders of GLF Warrants from time to time in the future and in amounts determined by such holders through their exercise of GLF
Warrants, subject to the limitations set forth in the Tidewater charter intended to assure Tidewater&#146;s compliance with the Jones Act, and the shares of Common Stock subject to this registration statement are being registered for this purpose.
</P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">This Post-Effective Amendment No.&nbsp;1 covers the offer and sale by Tidewater of the Common Stock that is issuable upon the exercise of
the GLF Warrants that are described in the preceding paragraph. No further offer or sale is being made by Tidewater pursuant to the Registration Statement and the prospectus included therein. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We previously paid to the SEC the entire registration fee relating to the Common Stock that is the subject of this Post-Effective Amendment

(the &#147;merger agreement&#148;). </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In accordance with the terms of the merger agreement and the applicable GLF Warrant Agreement (as
assumed and amended by Tidewater at the closing), each GLF Warrant represents the right to receive 1.100 shares of Common Stock upon payment to Tidewater of the applicable exercise price and subject to the other terms and conditions of the
applicable GLF Warrant Agreement, including cash paid in lieu of any fractional share. There are two series of GLF Warrants: GLF Jones Act Warrants, which may be exercised at any time until November&nbsp;14, 2042 for an exercise price of $0.01 per
share, and GLF Equity Warrants, which may be exercised at any time until November&nbsp;14, 2024 for an exercise price of $100.00 per share. Although all of the GLF Warrants are immediately exercisable, exercise of any GLF Warrants is subject to,
among other things, the limitations on foreign ownership as set forth in Tidewater&#146;s Amended and Restated Certificate of Incorporation (the &#147;Tidewater charter&#148;) that are intended to comply with the Merchant Marine Act of 1920 and the
Shipping Act, 1916, as amended, and the rules and regulations promulgated thereunder (collectively, the &#147;Jones Act&#148;). Immediately following the closing, there were 2,339,658 GLF Jones Act Warrants outstanding, representing the right to
purchase an aggregate of 2,573,624 shares of Common Stock and 783,009 GLF Equity Warrants outstanding, representing the right to purchase an aggregate 861,310 shares of Common Stock. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Tidewater will not receive any cash proceeds from the exercise of GLF Jones Act Warrants because, by their terms, these warrants may only be
exercised through a cashless exercise procedure, where the number of shares of Common Stock delivered upon exercise will be reduced by the number of shares of Common Stock necessary to cover the aggregate exercise price. Holders of GLF Equity
Warrants may elect either to exercise their warrants using a cashless exercise procedure or to pay the aggregate exercise price in cash. Tidewater will receive the proceeds from any cash exercise of the GLF Equity Warrants. If all GLF Equity
Warrants that were outstanding as of the closing were exercised for cash, we would receive gross proceeds of approximately $86,131,000. Any such proceeds would be used for general corporate purposes. </P>

the limitations on foreign ownership as set forth in the Tidewater charter that are intended to comply with the Jones Act. Immediately following the closing, there were 2,339,658 GLF Jones Act Warrants outstanding, representing the right to purchase

gas prices without a clear indication of if, or when, prices will recover to a level to support renewed offshore exploration activities; fleet additions by competitors and industry overcapacity; our limited capital resources available to replenish
our asset base, including through acquisitions or vessel construction, and to fund our capital expenditure needs; uncertainty of global financial market conditions and potential constraints in accessing capital or credit if and when needed with
favorable terms, if at all; changes in decisions and capital spending by customers in the energy industry and the industry expectations for offshore exploration, field development and production; consolidation of our customer base; loss of a major
customer; changing customer demands for vessel specifications, which may make some of our older vessels technologically obsolete for certain customer projects or in certain markets; rapid technological changes; delays and other problems associated
with vessel construction and maintenance; the continued availability of qualified personnel and our ability to attract and retain them; the operating risks normally incident to our lines of business, including the potential impact of liquidated
counterparties; our ability to comply with covenants in our indentures and other debt instruments; acts of terrorism and piracy; the impact of potential information technology, cybersecurity or data security breaches; integration of acquired
businesses and entry into new lines of business; disagreements with our joint venture partners; significant weather conditions; unsettled political conditions, war, civil unrest and governmental actions, such as expropriation or enforcement of
customs or other laws that are not well developed or consistently enforced; the risks associated with our international operations, including local content, local currency or similar requirements especially in higher political risk countries where
we operate; interest rate and foreign currency fluctuations; labor changes proposed by international conventions; increased regulatory burdens and oversight; changes in laws governing the taxation of foreign source income; retention of skilled
workers; enforcement of laws related to the environment, labor and foreign corrupt practices; the effects of asserted and unasserted claims and the extent of available insurance coverage; and the resolution of pending legal proceedings. </P>

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">As a result of the business combination, Tidewater assumed the GLF Warrants and will be obligated to issue shares of Common Stock to the
holders of GLF Warrants from time to time in the future, in amounts determined by such holders through their exercise of these GLF Warrants, subject to the limits set forth in the Tidewater charter intended to comply with the Jones Act, and the
shares of Common Stock subject to this registration statement are being registered for this purpose. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">There are two series of GLF
Warrants: GLF Jones Act Warrants, which may be exercised at any time until November&nbsp;14, 2042 for an exercise price of $0.01 per share, and GLF Equity Warrants, which may be exercised at any time until November&nbsp;14, 2024 for an exercise
price of $100.00 per share. Each series of GLF Warrant is subject to the terms and conditions of a warrant agreement, which was amended in connection with the business combination and assumed by Tidewater effective upon the closing (the &#147;GLF
Jones Act Warrant Agreement&#148; and the &#147;GLF Equity Warrant Agreement&#148; and together, the &#147;GLF Warrant Agreements&#148;). Although all of the GLF Warrants are immediately exercisable, exercise of any GLF Warrants is subject to, among
other things, the limitations on foreign ownership as set forth in the Tidewater charter that are intended to comply with the Jones Act. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Specifically, the Jones Act, which applies to companies that engage in maritime transportation of merchandise and passengers between points in
the United States (known as marine cabotage services or coastwise trade), requires, among other things, that the aggregate ownership of common stock of a publicly-traded company by <FONT STYLE="white-space:nowrap">non-U.S.</FONT> citizens not exceed
25% of its outstanding common stock. Therefore, in order to ensure compliance with the Jones Act, Tidewater&#146;s charter restricts ownership of the total number of shares of capital stock by all <FONT STYLE="white-space:nowrap">non-U.S.</FONT>
citizens to not more than 24% in the aggregate and restricts ownership of the total number of shares of capital stock by any individual <FONT STYLE="white-space:nowrap">non-U.S.</FONT> citizen to not more than 4.9%. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">As adjusted by the merger agreement and the applicable GLF Warrant Agreement, each GLF Warrant represents the right to receive 1.100 shares of
Common Stock upon payment to Tidewater of the applicable exercise price and subject to the other terms and conditions of the applicable GLF Warrant Agreement, including the limitations on foreign ownership as set forth in the Tidewater charter that
are intended to comply with the Jones Act. As provided in the applicable GLF Warrant Agreement, no fractional shares will be issued upon the exercise of GLF Warrants; rather, in exchange for payment of the applicable aggregate <FONT
STYLE="white-space:nowrap">per-share</FONT> exercise price, an exercising warrantholder will be entitled to receive a number of shares of Common Stock equal to all GLF Warrants of that series being exercised by such holder multiplied by 1.100,
rounded down to the nearest whole share, with cash paid in lieu of any fractional share based on the closing price of a share of Common Stock on the NYSE on November&nbsp;14, 2018, the last trading day prior to the closing. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The authorized capital stock of Tidewater consists of 125,000,000 shares of common stock, par value $0.001 per share, of which 37,169,016 shares were
outstanding as of February&nbsp;15, 2019 and 3,000,000 shares of preferred stock, no par value per share, none of which were outstanding as of February&nbsp;15, 2019. As of February&nbsp;15, 2019, the outstanding shares of common stock were held by
729 stockholders of record. All outstanding shares of Tidewater common stock are fully paid and nonassessable. The unissued portion of Tidewater&#146;s authorized common stock are available for issuance as the Tidewater Board determines advisable.
</P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Tidewater has also established long-term incentive compensation plans as incentives for certain eligible employees and currently sponsors two such plans
&#150; the 2017 Stock Incentive Plan (the &#147;2017 Plan&#148;) and the Legacy GulfMark Management Incentive Plan (the &#147;GLF MIP&#148;), which Tidewater assumed in the business combination, converting the number of shares subject to outstanding
restricted stock units as well as the number of additional shares remaining available to grant to shares of Tidewater common stock based on the exchange ratio. The only type of long-term incentive award that Tidewater has outstanding is restricted
stock units. As of December&nbsp;31, 2018, there were 964,147 restricted stock units outstanding under the 2017 Plan and 180,302 restricted stock units outstanding under the GLF MIP, each of which represents the right to receive a share of Tidewater
common stock in the future, provided the applicable vesting conditions are met. Subject to the terms and conditions of the applicable plan and NYSE listing rules, Tidewater may issue up to 1,610,533 additional shares of common stock under the 2017
Plan and up to 714,569 additional shares of common stock under the GLF MIP. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In addition, immediately following the closing, Tidewater had five series of

sale leaseback agreements (the &#147;creditor warrants&#148; or the &#147;TDW Jones Act Warrants&#148;) who did not establish their status as U.S. Citizens during the Restructuring. Two series of warrants were assumed as a result of the business
combination: (1)&nbsp;GLF Equity Warrants and (2)&nbsp;GLF Jones Act Warrants. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The TDW Equity Warrants have

trade; accordingly, it is subject to the Jones Act, which, subject to limited exceptions, restricts maritime transportation between points in the United States (known as marine cabotage services or coastwise trade) to vessels built in the United
States, registered under the U.S. flag, manned by predominantly U.S. crews, and owned and operated by U.S. citizens within the meaning of the Jones Act. Under the Jones Act, at least 75% of the outstanding shares of each class or series of the
capital stock of Tidewater must be owned and controlled by U.S. citizens. In order to ensure compliance with the Jones Act coastwise citizenship requirement that at least 75% of Tidewater&#146;s outstanding common stock is owned by U.S. citizens,
the Tidewater certificate of incorporation restricts ownership of the shares of its outstanding common stock by <FONT STYLE="white-space:nowrap">non-U.S.</FONT> citizens in the aggregate to not more than 24%. The Tidewater certificate of
incorporation further prohibits the acquisition of shares by a <FONT STYLE="white-space:nowrap">non-U.S.</FONT> citizen where (i)&nbsp;such acquisition would cause the aggregate number of shares held by all
<FONT STYLE="white-space:nowrap">non-U.S.</FONT> citizens to exceed 24% of Tidewater&#146;s issued and outstanding common stock and (ii)&nbsp;such acquisition would cause the aggregate number of shares held by any individual <FONT
STYLE="white-space:nowrap">non-U.S.</FONT> citizen to exceed 4.9% of Tidewater&#146;s issued and outstanding common stock. The Tidewater certificate of incorporation further provides the Tidewater Board with authority to redeem any share of common
stock that is owned by <FONT STYLE="white-space:nowrap">non-U.S.</FONT> citizens that would result in ownership by <FONT STYLE="white-space:nowrap">non-U.S.</FONT> citizens in the aggregate in excess of 24% of Tidewater&#146;s issued and outstanding
common stock. The Tidewater certificate of incorporation further provides that Tidewater may require beneficial owners of its common stock to confirm their citizenship from time to time through written statement or affidavit and could, in the
discretion of the Tidewater Board, suspend the voting rights of such beneficial owner, pay into an escrow account dividends or other distributions (upon liquidation or otherwise) with respect to such shares held by such beneficial owner and

Section&nbsp;203 of the DGCL generally prohibits any &#147;business combination,&#148; including mergers, sales and leases of assets, issuances of securities and similar transactions, by a corporation or a subsidiary with an &#147;interested
stockholder&#148; who beneficially owns 15% or more of a corporation&#146;s voting stock, within three years after the person or entity becomes an interested stockholder, unless: (i)&nbsp;the transaction that will cause the person or entity to
become an interested stockholder is approved by the board of directors of the corporation prior to the transaction; (ii)&nbsp;after the completion of the transaction in which the person or entity becomes an interested stockholder, the interested
stockholder holds at least 85% of the voting stock of the corporation not including shares held by officers and directors of interested stockholders or shares held by specified employee benefit plans; or (iii)&nbsp;after the person or entity becomes

stock that is (i)&nbsp;listed on a National Securities Exchange, (ii)&nbsp;authorized for quotation on an interdealer quotation system of a registered national securities association or (iii)&nbsp;held of record by more than 2,000 stockholders. </P>

certificate of incorporation requires the affirmative vote of at least 80% of the voting power of the outstanding shares of Tidewater&#146;s capital stock, voting together as a single class, to amend, repeal or adopt any provision inconsistent with
the provision of its charter prohibiting stockholders acting by written consent. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><I>Size of Tidewater Board and Vacancies</I>. Subject to the Specified
Period Governance Provisions, the Tidewater bylaws provide that the Tidewater Board shall consist of five or more members, the exact number to be fixed by the Tidewater Board from time to time. The Tidewater bylaws further provide that, subject to
the rights of holders of any series of preferred stock to elect directors under specific circumstances, any newly created directorships resulting from an increase in the authorized number of directors and any vacancies occurring in the Tidewater
Board, may be filled by the affirmative vote of a majority of the remaining members of the board, although less than a quorum, or a sole remaining director. The Tidewater bylaws require that immediately following the closing, the Tidewater Board
consist of ten members, three of which will be GulfMark designated directors. In addition, the Tidewater bylaws require that, subject to applicable law and the directors&#146; fiduciary duties, each of the three GulfMark designated directors (or a
replacement candidate as provided in the bylaws) will be included in the slate of nominees recommended by the Tidewater Board to the Tidewater stockholders for election at the 2019 annual meeting of stockholders (together with other bylaw provisions
specifically adopted to enforce these commitments, the &#147;Specified Period Governance Provisions&#148;). </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><I>Amendments of the Tidewater Bylaws</I>.
The Tidewater bylaws may only be adopted, amended, or repealed by either a majority of Tidewater&#146;s directors and a majority of Tidewater&#146;s continuing directors, voting as a separate group (except that in order to amend, modify or repeal
the Specified Governance Provisions, a vote of at least 85% of the Tidewater Board at the time of such amendment, repeal or modification is required), or the holders of at least 80% of the total voting power of all stockholders and <FONT
STYLE="white-space:nowrap">two-thirds</FONT> of the total voting power of stockholders, other than any related person, present or duly represented at a stockholders&#146; meeting voting as a separate group. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><I>Limitations on Ownership by <FONT STYLE="white-space:nowrap">Non-U.S.</FONT> Citizens</I>. Because Tidewater owns and operates U.S.-flag vessels in U.S.
coastwise trade, it is subject to the Jones Act, which, subject to limited exceptions, restricts maritime transportation between points in the United States (known as marine cabotage services or coastwise trade) to vessels built in the United
States, registered under the U.S. flag, manned by predominantly U.S. crews, and owned and operated by U.S. citizens within the meaning of the Jones Act. Under the Jones Act, at least 75% of the outstanding shares of each class or series of the
capital stock of Tidewater must be owned and controlled by U.S. citizens. In order to ensure compliance with the Jones Act coastwise citizenship requirement that at least 75% of Tidewater&#146;s outstanding common stock is owned by U.S. citizens,
the Tidewater certificate of incorporation restricts ownership of the shares of its outstanding common stock by <FONT STYLE="white-space:nowrap">non-U.S.</FONT> citizens in the aggregate to not more than 24%. The Tidewater certificate of
incorporation further prohibits the acquisition of shares by a <FONT STYLE="white-space:nowrap">non-U.S.</FONT> citizen where (i)&nbsp;such acquisition would cause the aggregate number of shares held by all
<FONT STYLE="white-space:nowrap">non-U.S.</FONT> citizens to exceed 24% of Tidewater&#146;s issued and outstanding common stock and (ii)&nbsp;such acquisition would cause the aggregate number of shares held by any individual <FONT
STYLE="white-space:nowrap">non-U.S.</FONT> citizen to exceed 4.9% of Tidewater&#146;s issued and outstanding common stock. The Tidewater certificate of incorporation further provides the Tidewater Board with authority to redeem any share of common
stock that is owned by <FONT STYLE="white-space:nowrap">non-U.S.</FONT> citizens that would result in ownership by <FONT STYLE="white-space:nowrap">non-U.S.</FONT> citizens in the aggregate in excess of 24% of Tidewater&#146;s issued and outstanding
common stock. The Tidewater certificate of incorporation also provides that Tidewater may require beneficial owners of its common stock to confirm their citizenship from time to time through written statement or affidavit and could, in the
discretion of the Tidewater Board, suspend the voting rights of such beneficial owner, pay into an escrow account dividends or other distributions (upon liquidation or otherwise) with respect to such shares held by such beneficial owner and
restrict, prohibit or void the transfer of such shares and refuse to register such shares of Tidewater common stock held by such beneficial owner until confirmation of its citizenship status is received. </P>
