Service

Hamilton, Bermuda, December 6, 2006

Nordic American Tanker Shipping Ltd. (the "Company") today announced that the
Company has taken delivery of the last of the three suezmax vessels that it

vessels since the autumn of 2004. All the vessels of the Company are modern

The vessel is increasing the Company's exposure to the spot market from ten to
eleven vessels, whilst the Company's twelfth vessel is employed on a long term
contract.

the Company. This transaction is in line with the Company's growth strategy with

the Company.


            CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Matters discussed in this press release may constitute forward-looking
statements. The Private Securities Litigation Reform Act of 1995 provides safe
harbor protections for forward-looking statements in order to encourage
companies to provide prospective information about their business.
Forward-looking statements include statements concerning plans, objectives,
goals, strategies, future events or performance, and underlying assumptions and
other statements, which are other than statements of historical facts.

The Company desires to take advantage of the safe harbor provisions of the
Private Securities Litigation Reform Act of 1995 and is including this
cautionary statement in connection with this safe harbor legislation. The words
"believe," "anticipate," "intend," "estimate," "forecast," "project," "plan,"
"potential," "will," "may," "should," "expect," "pending" and similar
expressions identify forward-looking statements.

The forward-looking statements in this press release are based upon various
assumptions, many of which are based, in turn, upon further assumptions,
including without limitation, our management's examination of historical
operating trends, data contained in our records and other data available from
third parties. Although we believe that these assumptions were reasonable when
made, because these assumptions are inherently subject to significant
uncertainties and contingencies which are difficult or impossible to predict and
are beyond our control, we cannot assure you that we will achieve or accomplish
these expectations, beliefs or projections. We undertake no obligation to update
any forward-looking statement, whether as a result of new information, future
events or otherwise.

Important factors that, in our view, could cause actual results to differ
materially from those discussed in the forward-looking statements include the
strength of world economies and currencies, general market conditions, including
fluctuations in charter rates and vessel values, changes in demand in the tanker
market, as a result of changes in OPEC's petroleum production levels and world
wide oil consumption and storage, changes in our operating expenses, including
bunker prices, drydocking and insurance costs, the market for our vessels,
availability of financing and refinancing, changes in governmental rules and
regulations or actions taken by regulatory authorities, potential liability from
pending or future litigation, general domestic and international political
conditions, potential disruption of shipping routes due to accidents or
political events, vessels breakdowns and instances of off-hires and other
important factors described from time to time in the reports filed by the
Company with the Securities and Exchange Commission, including the prospectus
and related prospectus supplement, our Annual Report on Form 20-F, and our
reports on Form 6-K.
