INFORMATION CONTAINED IN THIS FORM 6-K REPORT

agreed to purchase another two Suexmax vessels.

Exhibit 1


               Nordic American Tanker Shipping Ltd. - (NYSE: NAT)
           Announces Agreement to Purchase Another Two Suezmax Vessels

Hamilton, Bermuda, July 31, 2006

Nordic  American  Tanker  Shipping Ltd. (the "Company" or "NAT") today announced
that it has agreed to acquire its eleventh  and twelfth  Suezmax  tanker.  These
vessels,  one  built in 2002 and one in 2003 in the  Samsung  shipyard  in South
Korea,  are sister  vessels to the  Company's  tenth  vessel  (built 2003) whose
acquisition  was  announced on July 17. While the tanker  market is volatile and
difficult to predict,  our analysis shows that the spot market results in higher
average rates than those achieved in the fixed term-charter  market.  Therefore,
it is presently  anticipated that these vessels will be employed in spot or spot
related  business,  like  all but one of the  Company's  existing  vessels.  The
aggregate  price for the three sister  vessels is $ 246m. All the twelve vessels
of the Company have double hull.

NAT has several  sister vessels in its fleet.  The Company's  experience is that
sister vessels  provide for  particular  efficiency as regards  operating  costs
through  interchange  of spare  parts  and  greater  ease of crew  training.  In
addition, the Company believes that being able to offer sister vessels increases
their  attraction to potential  customers who wish to charter a specific  vessel
type.

Herbjorn Hansson, the Company's Chairman and Chief Executive Officer stated: "By
increasing our fleet to twelve Suezmax tankers, we believe that we shall be able
to realize increased  operational  efficiencies and it will help us in providing
for a stronger market presence, having one of the largest and most modern fleets
of  double  hull  Suezmax  tankers.  These  acquisitions  will not  require  any
significant increase in the Company's overhead costs, and, therefore,  we should
be  able to  reduce  our  overhead  costs  per  vessel.  We  expect  that  these
acquisitions  will result in higher  dividend  and  earnings  per share than had
these  vessels not been  acquired.  Growth will remain an essential  part of our
operating  model."  Together with the acquisition that was announced on July 17,
the Company  expects  that these two  vessels  also will join its fleet no later
than by the end of November 2006.  Financing for these  acquisitions is expected
to consist of a combination of debt and equity.

            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-hire,  failure on the
part of a seller to complete a sale to us 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.
