CUSIP No. Y2106R110

AMENDMENT NO. 6 TO SCHEDULE 13D

This Amendment No. 6 to Schedule 13D (this "Amendment No. 6") amends and restates in its entirety the Schedule 13D filed on January 4, 2016 (the "Original Schedule 13D", as amended and restated by Amendment No. 5 on March 17, 2021, "Amendment No. 5,"). This Amendment No. 6 is being filed to report the Reporting Person's (as defined below) entry into the April 2021 Prepaid Forward Contract (as defined below).

ITEM 1. Security and Issuer.

This Schedule 13D relates to the Common Shares, par value $0.01 per share (the "Common Shares") of Dorian LPG Ltd., a Marshall Islands corporation (the "Issuer"), whose principal executive offices are located at 27 Signal Road, Stamford, Connecticut 06902.

ITEM 2. Identity and Background.

(a) – (c), (f) This Schedule 13D is being filed by John C. Hadjipateras, a United States citizen (the "Reporting Person"). The Reporting Person's business address is c/o Dorian LPG (USA) LLC, 27 Signal Road, Stamford, CT 06902. The Reporting Person is the Chief Executive Officer, President and Chairman of the Board of Directors of the Issuer.

(d) – (e) The Reporting Person has not, during the last five years, (i) been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors), or (ii) been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violations with respect to such laws.

ITEM 3. Source and Amount of Funds or Other Consideration.

On July 29, 2013, Theodore B. Young and Alexander J. Ciaputa (each an "Employee Shareholder" and collectively, the "Employee Shareholders") entered into separate non-negotiable promissory notes and funding and security agreements (collectively, the "Lending and Security Agreements") with the Reporting Person. Pursuant to the Lending and Security Agreements, the Reporting Person lent an aggregate of $352,408 to the Employee Shareholders to purchase an aggregate of 26,166 Common Shares (as adjusted to reflect the one-for-five reverse stock split effected by the Issuer on April 25, 2014) (the "Employee Shares") and the Employee Shareholders pledged the Employee Shares to the Reporting Person as security for the loans.

On December 22, 2015, as part of a pro rata distribution by Astromar LLC to its members, the Reporting Person received 1,540,155 Common Shares over which he has sole dispositive and voting power. No consideration was paid as part of the distribution. The other 631,403 Common Shares to which the Reporting Person has sole dispositive and voting power were acquired with cash on hand and through awards of restricted stock from the Issuer.

In addition, on December 22, 2015, Mark C. Hadjipateras, Angeliki C. Hadjipateras, Aikaterini C. Hadjipateras, Konstantinos Markakis, Scott M. Sambur, as Trustee of the Kyveli Trust, and George J. Dambassis (each a "Proxy Shareholder" and collectively, the "Proxy Shareholders"), who together are record holders of an aggregate 2,708,557 Common Shares (the "Proxy Shares"), each entered into a separate revocable proxy (each a "Shareholder Proxy" and collectively, the "Shareholder Proxies") appointing the Reporting Person, with respect to the Proxy Shares, as such Proxy Shareholder's proxy, attorney, and agent with full power and authority, at any meeting of shareholders of the Issuer, whether attending in person or by proxy, and on every action or written consent of shareholders of the Issuer, to vote and act for and in such Proxy Shareholder's name, place and stead. No consideration was paid by the Reporting Person in connection with each Shareholder Proxy.

On December 22, 2015, Olympia Kedrou and Chrysanthi Xyla (each a "KX Proxy Shareholder" and collectively, the "KX Proxy Shareholders"), who together were record holders of an aggregate 886,756  Common Shares (the "KX Proxy Shares"), also each entered into a separate revocable proxy (each a "KX Shareholder Proxy") appointing the Reporting Person, with respect to the KX Shares, as each such KX Proxy Shareholder's proxy, attorney, and agent with full power and authority, at any meeting of shareholders of the Issuer, whether attending in person or by proxy, and on every action or written consent of shareholders of the Issuer, to vote and act for and in such  KX Proxy Shareholder's name, place and stead. No consideration was paid by the Reporting Person in connection with each KX Shareholder Proxy. It has come to the attention of the Reporting Person that Olympia Kedrou and Chrysanthi Xyla passed away and the KX Proxy Shares are in the process of being transferred to their respective heirs.  As a result, the Reporting Person is no longer the proxyholder for the KX Proxy Shareholders and is no longer deemed to beneficially own the KX Proxy Shares.  The Reporting Person's beneficial ownership has been reduced accordingly.

The Lending and Security Agreements and the Shareholder Proxies are incorporated by reference in this filing in Exhibit A and Exhibit B, respectively, and any references to or descriptions of the Lending and Security Agreements and the Shareholder Proxies are qualified in their entirety by reference to the full text of the Lending and Security Agreements and the Shareholder Proxies, respectively.

ITEM 4. Purpose of Transaction.

(a) - (j). The Common Shares that the Reporting Person may be deemed to beneficially own are held for investment or other purposes, but as the Chief Executive Officer, President and Chairman of the Board of Directors of the Issuer, the Reporting Person controls the management and policies of the Issuer. In the future, the Reporting Person may be involved in and may plan for his involvement in any or all of the following:

1.	The acquisition of additional Common Shares of the Issuer or the disposition of Common Shares of the Issuer;
2.	Any extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries;
3.	A sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries;
4.	Any material change in the present capitalization or dividend policy of the Issuer;
5.	Any other material change in the Issuer's business or corporate structure;
6.	Changes in the Issuer's charter, by-laws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person;
7.	Causing a class of securities of the Issuer to be delisted from a national securities exchange or to cease to be authorized to be quoted on an inter-dealer quotation system of a registered national securities association;
8.	A class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act; and
9.	Any action similar to those enumerated above.

Any future decision of the Reporting Person to take any such actions with respect to the Issuer or its securities will take into account various factors, including the prospects of the Issuer, general market and economic conditions and other factors deemed relevant.

ITEM 5. Interest in Securities of the Issuer.

(a) – (b) Based on information provided by the Issuer, the Issuer had 41,481,844 Common Shares outstanding as of the date hereof. Based upon the foregoing, as of the date hereof, the Reporting Person may be deemed to beneficially own 4,767,623 Common Shares representing 11.5% of the total outstanding Common Shares, further as set forth below:

Name	Voting		Dispositive
