INFORMATION CONTAINED IN THIS FORM 6-K REPORT

     Attached  hereto  as  Exhibit 1 is a copy of the  press  release  issued by
Nordic  American  Tanker  Shipping  Limited on September 6, 2006,  announcing an
agreement to increase its credit facility to $500 million.







                                                                       Exhibit 1

Nordic  American  Tanker  Shipping  Ltd. - (NYSE:  NAT)  Announces  Agreement to
Increase Credit Facility to $500 million

Hamilton, Bermuda, September 6th, 2006

Nordic American Tanker  Shipping,  Ltd. (the "Company" or "NAT") today announced
that its lenders have agreed to increase the Company's Revolving Credit Facility
to $500 million from the present $300 million,  on the same terms as the present
Credit Facility. The lenders are among the top shipping banks in the world.

Herbjorn  Hansson,  the Company's  Chairman and Chief Executive  Officer stated,
"The increased Credit Facility with no change in terms demonstrates our lenders'
confidence  in NAT and its  operating  model.  We have  recently  announced  our
agreements  to acquire  three  additional  modern  double hull Suezmax  tankers,
bringing our fleet to twelve  vessels by the end of November.  This  increase of
our Credit  Facility to $500 million will enhance our financial  flexibility and
assist us in executing our plan of growing the Company's  fleet further  through
acquisitions  which bolster the earnings and dividend capacity per share.  While
the spot market is always volatile and can change without notice,  the market is
currently strong with good capacity utilization".

            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.
