Exhibit 1


Nordic American Tanker Shipping Ltd. - (NYSE: NAT) Now Eleven Vessels are in
Service

Hamilton, Bermuda, November 27,  2006

Nordic American  Tanker  Shipping Ltd. (the "Company")  today announced that the
Company has taken  delivery  of the suezmax  vessel that it agreed to acquire in
July this year.  The 2002 built suezmax has been named Nordic Moon and was taken
over today November 27, 2006. Including the Nordic Moon the fleet of the Company
has increased from three to eleven suezmax vessels over the last 24 months.

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

In early  December  the Company  expects to take  delivery  of one more  suezmax
vessel that it also agreed to acquire in July this year, increasing the fleet to
twelve vessels.

The increased fleet  represents an important step in the further  development of
the Company. This transaction is in line with the Company's growth strategy with
focus on dividend and earnings per share,  bolstering  the earnings  capacity of
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.
