         RE:      TEEKAY SHIPPING CORPORATION
                  REGISTRATION STATEMENT ON FORM F-4

Dear Sirs:

     We have acted as counsel to Teekay Shipping Corporation, a Republic of The
Marshall Islands corporation (the "Company"), in connection with its offer to
exchange $1,000 principal amount of 8.875% Senior Notes due 2011 of the Company
(the "Exchange Notes"), for each $1,000 principal amount of the outstanding
unregistered 8.875% Senior Notes due 2011 of the Company (the "Private Notes"),
which Exchange Notes are the subject of the Registration Statement on Form F-4
(as amended, the "Registration Statement"), filed by the Company today with the
Securities and Exchange Commission under the Securities Act of 1933, as amended
(the "Securities Act"), and the rules and regulations promulgated thereunder
(the "Rules"). The Exchange Notes will be issued pursuant to an Indenture (the
"Indenture") dated June 22, 2001, between the Company and U.S. Trust Company of
Texas, N.A., as Trustee (the "Trustee"). You have asked us to render our opinion
as to the matters hereinafter set forth. Capitalized terms used but not defined
herein shall have the same meaning as in the Registration Statement.

     In the course of our representation as described above, we have examined
originals, or copies certified or otherwise identified to our satisfaction, of
the documents described in Schedule A hereto. The documents listed in Schedule A
are herein collectively referred to as the "Documents." Our opinions are based
solely

upon a review of the Documents and, with your consent, we have reviewed no other
documents, corporate records, certificates or other statements as a basis for
the opinions expressed herein.

     As to matters of fact bearing upon the opinions expressed herein, we have,
with your consent and without further investigation, relied upon information in
certificates provided to us by the Company's directors and officers.

     In rendering the opinions expressed herein, we have further relied upon the
following assumptions, the accuracy of which we have not independently verified:

(a)  Each document submitted to us for review is accurate and complete, each
     such document that is an original is authentic, each such document that is
     a copy conforms to an authentic original, and all signatures on each such
     document are genuine.

(b)  The Company is validly existing under applicable law.

(c)  The Company has the power, authority and legal right to execute and
     deliver, and to perform its obligations under, the Indenture and the
     Exchange Securities.

(d)  The Company has duly authorized, executed and delivered the Indenture and
     any other certificates, instruments or documents (other than the Exchange
     Notes) required to be executed and delivered in connection therewith.

(e)  The Exchange Notes have been duly authorized, executed and issued by the
     Company and duly authenticated by the Trustee.

(f)  Each of the Company and the Trustee has satisfied those legal requirements
     applicable to it that are necessary to make the Indenture and any other
     certificates, instruments or documents (other than, with respect to the
     Company, the Exchange Notes) required to be executed and delivered by it in
     connection therewith enforceable against such party in accordance with
     their respective terms.

OPINION

     Based upon the foregoing examinations and assumptions and subject to the
qualifications and exclusions stated below, we are of the opinion that:

     1.   Upon (a) the Registration Statement becoming effective under the
Securities Act, (b) qualification of the Indenture under the Trust Indenture Act
of 1939, as amended, and (c) delivery of the Exchange Notes in exchange for the
Private Notes as contemplated by the Registration Statement, the Exchange Notes
will constitute valid and binding obligations of the Company, enforceable
against the Company in accordance with their terms.

     2.   The summary set forth under the heading "Tax Considerations -- United
States Federal Income Tax Considerations" in the final prospectus forming a part
of the Registration Statement is accurate and describes the material United
States federal income tax consequences expected to be relevant to the recipients
of Exchange Notes in exchange for Private Notes who were initial purchasers of
the Private Notes, acquired the Private Notes as a capital asset, are United
States persons and are not among particular categories of investors subject to
special treatment under certain United States federal income tax laws. This
opinion is based on provisions of the United States Internal Revenue Code of
1986, as amended, applicable United States Treasury Department Regulations,
published administrative positions and judicial decisions, all existing as of
the date hereof.

qualifications:

          a.   Our opinions are as of the date hereof and we have no
responsibility to update this opinion for events and circumstances occurring
after the date hereof or as to facts relating to prior events that are
subsequently brought to our attention. We disavow any undertaking to advise you
of any changes in law.

          b.   We express no opinion as to enforceability of any right or
obligation to the extent such right or obligation is subject to and limited by
(i) the effect of bankruptcy, insolvency, reorganization, receivership,
conservatorship, arrangement, moratorium, fraudulent transfer or other laws
affecting or relating to the rights of creditors generally or (ii) the rules
governing the availability of specific performance, injunctive relief or other
equitable remedies and general principles of equity, regardless of whether
arising prior to, or after, the date hereof or considered in a proceeding in
equity or at law.
