Item 4.01 Changes in Registrant's Certifying Accountant.

     On March 27, 2006, our Audit Committee dismissed PricewaterhouseCoopers LLP
("PricewaterhouseCoopers")  as our independent registered public accounting firm
and  approved  the  appointment  of  Deloitte  & Touche  LLP as our  independent
registered public accounting firm to audit our financial statements for the year
ending December 31, 2006. On March 27, 2006, our Board of Directors ratified the
Audit Committee's  decision to change  independent  registered public accounting
firms and the appointment of Deloitte & Touche.

     The audit reports of  PricewaterhouseCoopers  on our consolidated financial
statements for each of the two fiscal years ended December 31, 2004 and 2005 did
not  contain  any  adverse  opinion  or  disclaimer  of  opinion,  nor were they
qualified or modified as to uncertainty,  audit scope or accounting  principles,
except that its report for each year included an explanatory paragraph regarding
our wholly owned subsidiary, The Babcock & Wilcox Company.

     During the two fiscal years ended  December 31,  2005,  and the  subsequent
interim period through March 27, 2006,  there were no  disagreements  between us
and  PricewaterhouseCoopers on any matter of accounting principles or practices,
financial   statement   disclosure  or  auditing   scope  or  procedure,   which
disagreements,  if not resolved to the  satisfaction of  PricewaterhouseCoopers,
would have caused PricewaterhouseCoopers to make reference to the subject matter
of the  disagreement in connection with its reports on the financial  statements
for such years.

     During the two years ended December 31, 2005,  and the  subsequent  interim
period  through  March 27,  2006,  there have been no  "reportable  events,"  as
defined in Item  304(a)(1)(v)  of  Regulation  S-K,  except as  described in the
following paragraph.

     In March  2004,  PricewaterhouseCoopers  advised us of a material  weakness
relating  to  our  ability  to  forecast  accurately  total  costs  to  complete
fixed-price  contracts,  primarily  first-of-a-kind  projects. We discussed this
material  weakness in Item 9A in our Form 10-K for the year ended  December  31,
2003.  In  connection  with the  audit  of the year  ended  December  31,  2004,
PricewaterhouseCoopers  reported material  weaknesses  related to the following:
(1) account  reconciliations in our Marine Construction  Services segment in the
Eastern  Hemisphere  related to cash and cash equivalents,  accounts payable and
other accounts were not being properly completed;  and (2) control  deficiencies
at our business units with respect to access to financial  application  programs
and data which included lack of compliance  with the Company's  internal  access
security policies and segregation of duties requirements and lack of independent
monitoring of the activities of technical information  technology staff and some
users with financial  accounting and reporting  responsibilities  that also have
unrestricted  access to financial  application  programs and data.  We discussed
these  material  weaknesses  in Item 9A in our  Form  10-K  for the  year  ended
December 31, 2004.

     As  disclosed  in Item 9A in our Form 10-K for the year ended  December 31,
2005,  management  conducted an assessment of the  effectiveness of our internal
control  over  financial  reporting  as of  December  31,  2005.  Based  on this
assessment,  management  concluded  that our  internal  control  over  financial
reporting was effective as of December 31, 2005.  Management's assessment of the
effectiveness  of our internal  control over financial  reporting was audited by
PricewaterhouseCoopers,  whose  unqualified  report thereon also appears in such
10-K.

                                       2



     During  the two  fiscal  years  ended  December  31,  2005,  and during the
subsequent interim period preceding the appointment of Deloitte & Touche LLP, we
had not consulted  with Deloitte & Touche LLP regarding (i) the  application  of
accounting principles to a specified transaction,  either completed or proposed,
or the  type of  audit  opinion  that  might  be  rendered  on our  consolidated
financial  statements  or (2) any  matter  that  was  either  the  subject  of a
"disagreement,"  as  defined  in Item  304(a)(1)(iv)  of  Regulation  S-K,  or a
"reportable event" described in Item 304(a)(1)(v) of Regulations S-K.
