Attached as Exhibit 1 is the interim report of Knightsbridge Tankers Limited
dated August 11, 2006, with respect to its interim results for the second
quarter of 2006.


                                                                 Exhibit 1

Knightsbridge Tankers Limited

Interim Report June 2006

SECOND QUARTER AND SIX MONTHS RESULTS

Knightsbridge Tankers Limited (the "Company") reports net income of $7.9 million
and  earnings  per share of $0.46 for the second  quarter of 2006.  The  average
daily time charter  equivalents  ("TCEs") earned by the Company's five VLCCs was
$42,800 compared with $54,300 in the immediately  preceding quarter.  The second
quarter earnings reflect the weakening of the tanker market that occurred in the
first quarter and early into the second quarter of 2006 before a steady recovery
that continued  through the end of the second quarter.  Net interest expense for
the quarter was $1.3 million (2005 comparable quarter: $1.0 million) and at June
30, 2006, all of the Company's debt is floating rate debt. As of August 7, 2006,
the Company has an average  cash  breakeven  rate for its vessels of $19,200 per
vessel per day compared to $18,900 on May 8, 2006. This increase is as result of
increased general market interest rates.

The  completion  of the  drydocking  for TI Ningbo  (formerly  named  Hampstead)
resulted in  approximately  18.3 days of off-hire in the second quarter.  All of
the  Company's  five  vessels  have  now  completed  their  scheduled  ten  year
drydocking and special survey.

The net decrease in cash and cash  equivalents  in the quarter was $6.8 million.
The Company generated cash from operating activities of $13.2 million, used $2.9
million to repay the Company's loan and credit  facilities and distributed $17.1
million in dividend payments.

For the six months  ended June 30, 2006 the Company  reports net income of $22.1
million and  earnings  per share of $1.29.  The  average  daily TCEs for the six
months ended June 30, 2006 was $48,600.  Net interest expense for the period was
$2.6 million (2005 comparable six months: $1.8 million).

On August 11, 2006, the Board declared a dividend of $0.80 per share. The record
date for the  dividend is August 25, 2006,  ex dividend  date is August 23, 2006
and the dividend will be paid on or about September 8, 2006.

THE MARKET

The  downward  pressure at the end of the first  quarter for VLCCs eased late in
the first week of the second quarter.  The lowest rate in the second quarter was
witnessed in the first week of April with  approximately  World Scale ("WS") 55,
for the  benchmark  route MEG to Japan.  This equated to a TCE of  approximately
$18,500  per day.  The  benchmark  rate  increased  gradually  until mid May and
thereafter  accelerated to its high of approximately WS 120 ($80,500 per day) in
the third week of June.  The  quarter  ended  with the VLCC  market in a gradual
decline to approximately WS 97 ($58,500/day).

The  average  rate  from  the MEG to  Japan in the  second  quarter  of 2006 was
approximately WS 80 ($41,700 per day), compared to about WS 71 ($32,600 per day)
in the second quarter of 2005.

Bunkers  continued  the upward trend seen in the first  quarter with  Fujairah's
highest  bunker quote for the quarter  early May at $359 per mt, for  thereafter
slowly  decreasing  to $325 per mt at the end of the quarter  with an average of
$335 per mt. This  represents an increase from the average in the second quarter
of 2005 of $79/mt.

The  International  Energy  Agency  (IEA)  reported in July an average  OPEC Oil
production,  including  Iraq, of 29.68 million barrels per day during the second
quarter of the year, a 0.19 million barrels per day or 0.6 percent decrease from
the first quarter.  OPEC decided at its extraordinary meeting held in Caracas on
June 1 to maintain current  production  levels.  The Conference's  next ordinary
meeting is to take place in Vienna on September 11, 2006.

IEA estimates that world oil demand averaged 83.3 million barrels per day in the
second  quarter,  a 1.9 percent  increase  from the first  quarter of 2006.  IEA
further  predicts that the average demand for 2006 in total will be 84.8 million
barrels per day, or a 1.5 percent growth from 2005,  hence showing a firm belief
in continued demand growth.

According  to  Fearnleys  the VLCC fleet  totalled 473 vessels at the end of the
second  quarter of 2006,  an increase of 0.9 percent over the quarter.  No VLCCs
were scrapped in the period whilst four were delivered. The total order book now
stands at 149  vessels at the end of the  second  quarter,  up from 130  vessels
after the first  quarter  of 2006.  For the  remainder  of 2006  there are seven
deliveries  expected and there are 32 counted for 2007.  The current  order book
represents  31.5  percent of the current  VLCC  fleet.  A total of 23 VLCCs were
ordered during the quarter.

At the end of July it was possible to sell freight  futures for the remainder of
2006 at a level that equated to TCEs for VLCCs at approximately $84,000 per day.

OUTLOOK

In June  2006,  the  Company  announced  it had  entered  into new time  charter
agreements for its VLCCs: TI Ningbo and TI Qingdao.  The two VLCCs will commence
their new time charter employment  directly after the current charters expire in
the first  half of 2007.  The TI Ningbo and TI Qingdao  have been  chartered  to
Frontline  Ltd for a period of four and five  years,  respectively.  The charter
income for each VLCC will consist of a fixed base rate of $37,750 per day plus a
market related element being 50 percent of the difference  between a spot market
related rate index and the base rate.  The Board  believes that the new charters
will serve the Company well.  The new charters  create  secured  income into the
next decade and at the same time allow the  Company to benefit  from spot market
increases.

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.

Knightsbridge  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," "except," "anticipate," "intends," "estimate," "forecast," "project,"
"plan,"  "potential,"  "will," "may,"  "should,"  "expect"  "pending and similar
expressions identify forward-looking statements.

The  forward-looking   statements  in  this  document  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.

In addition to these  important  factors,  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 charterhire
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 Knightsbridge's operating expenses, including bunker prices,
drydocking  and  insurance  costs,  the  market  for  Knightsbridge's   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, and other important factors described from time to time in the
reports filed by Knightsbridge with the Securities and Exchange Commission.
