                                POWER OF ATTORNEY

                         For Executing Forms 3, 4 and 5

        Know all by these presents, that the undersigned hereby constitutes and
appoints each of Karim Mikhail, Thomas Reilly and Jacqueline Mercier, each
acting singly, the undersigned's true and lawful attorney-in-fact from the date
hereof to:

        (1)     Execute for and on behalf of the undersigned, in the
undersigned's capacity as an officer, director and/or 10% shareholder of Amarin
Corporation plc (the "Company"), forms and authentication documents for EDGAR
Filing Access;

        (2)     execute for and on behalf of the undersigned, in the
undersigned's capacity as an officer, director and/or 10% shareholder of the
Company, Forms 3, 4 and 5 in accordance with Section 16(a) of the Securities
Exchange Act of 1934 and the rules thereunder;

        (3)     do and perform any and all acts for and on behalf of the
undersigned that may be necessary or desirable to complete the execution of any
such Form 3, 4 or 5, complete and execute any amendment or amendments thereto,
and the timely filing of such form with the United States Securities and
Exchange Commission and any other authority; and

        (4)     take any other action of any type whatsoever in connection with
the foregoing which, in the opinion of such attorney-in-fact, may be of benefit
to, in the best interests of, or legally required by, the undersigned, it being
understood that the documents executed by such attorney-in-fact on behalf of
the undersigned pursuant to this Power of Attorney shall be in such form and
shall contain such terms and conditions as such attorney-in-fact may approve in
his discretion.

        The undersigned hereby grants to each such attorney-in-fact full power
and authority to do and perform all and every act and thing whatsoever
requisite, necessary, and proper to be done in the exercise of any of the
rights and powers herein granted, as fully for all intents and purposes as the
such attorney-in-fact might or could do if personally present, with full power
of substitution or revocation, hereby ratifying and confirming all that such
attorney-in-fact, or his substitute or substitutes, shall lawfully do or cause
to be done by virtue of this power of attorney and the rights and powers herein
granted. The undersigned acknowledges that the foregoing attorneys-in-fact, in
serving in such capacity at the request of the undersigned, are not assuming
any of the undersigned's responsibilities to comply with Section 16 of the
Securities Exchange Act of 1934, as amended.

        This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4, and 5 with respect to the
undersigned's holdings of and transactions in securities issued by the Company,
unless earlier revoked by the undersigned in a signed writing delivered to the
foregoing attorneys-in-fact.

        By this Power of Attorney, the undersigned further revokes all previous
powers of attorney relating to the undersigned's obligations to file Forms 3, 4
and 5 in respect of the Company's securities under Section 16(a) of the
Securities Exchange Act of 1934 and related matters.

        IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney
to be executed as of this March 2, 2023.
