          CHIEF EXECUTIVE OFFICER/CHIEF FINANCIAL OFFICER CERTIFICATION
            Pursuant to Section 302 of the Sarbanes-Oxley Act of 2002

I, Herbjorn Hansson, certify that:

1. I have  reviewed this annual  report on Form 20-F of Nordic  American  Tanker
Shipping Limited;

2.  Based on my  knowledge,  this  annual  report  does not  contain  any untrue
statement of a material fact or omit to state a material fact  necessary to make
the statements made, in light of the  circumstances  under which such statements
were made,  not  misleading  with  respect to the period  covered by this annual
report;  and

3.  Based  on my  knowledge,  the  financial  statements,  and  other  financial
information  included  in this annual  report,  fairly  present in all  material
respects the financial  condition,  results of operations  and cash flows of the
registrant as of, and for, the periods presented in this annual report.

4. I am responsible for  establishing  and maintaining  disclosure  controls and
procedures  (as  defined  in  Exchange  Act Rules  13a-14  and  15d-14)  for the
registrant and have:

a) designed  such  disclosure  controls and  procedures  to ensure that material
information relating to the registrant, including its consolidated subsidiaries,
is made known to me by others  within those  entities,  particularly  during the
period in which this annual report is being prepared;

b) evaluated  the  effectiveness  of the  registrant's  disclosure  controls and
procedures  as of a date  within 90 days prior to the filing date of this annual
report (the "Evaluation Date"); and

c) presented in this annual report my conclusions about the effectiveness of the
disclosure  controls and procedures  based on my evaluation as of the Evaluation
Date;

5. I have disclosed,  based on my most recent  evaluation,  to the  registrant's
auditors and the audit committee of registrant's  board of directors (or persons
performing the equivalent functions);

a) all significant  deficiencies in the design or operation of internal controls
which  could  adversely  affect the  registrant's  ability  to record,  process,
summarize and report  financial data and have  identified  for the  registrant's
auditors any material weaknesses in internal controls; and

b) any  fraud,  whether  or not  material,  that  involves  management  or other
employees who have a significant role in the registrant's internal controls; and

6. I have indicated in this annual report whether there were significant changes
in  internal  controls  or in other  factors  that  could  significantly  affect
internal  controls  subsequent  to the  date  of  our  most  recent  evaluation,
including any  corrective  actions with regard to significant  deficiencies  and
material weaknesses.
