OPERATING REVIEW
Acergy Africa and Mediterranean - The Erha and Okume projects were
satisfactorily completed and good progress made on EPC2B, which is now in its
final phase. With an increased scope of work, the installation phase of Greater
Plutonio began at the end of the fourth quarter with the new J-Lay system on the
Acergy Polaris performing ahead of expectations during this initial phase. Good
project results during the quarter compensated for the Acergy Polaris being out
of action for most of the quarter for a planned major upgrade. In the third
quarter of 2007 the challenging deepwater Moho Bilondo project moves into the
installation phase. 2006 was a
<PAGE>

good year for Africa and the Mediterranean with record revenues, high levels of
asset utilisation and timely project delivery.

Acergy Northern Europe and Canada - All of the ships in the North Sea again saw
high levels of utilisation in the fourth quarter. The Langeled contract was very
successfully completed with the Acergy Piper moving on to the Ekofisk pipelay at
quarter end. A divers' strike affected operations in the North Sea causing
delays and extra costs to reschedule programmes. We also experienced delays on
the Britannia Satellites project due to trenching difficulties and bad weather.
Despite these setbacks Northern Europe and Canada has again turned in a very
satisfying performance for the full year.

Acergy North America and Mexico - The fourth quarter saw further deterioration
in the discontinued operations on the remaining project in Trinidad due
primarily to project close-out costs. This project was substantially completed
in January 2007. The break even result from continuing operations was achieved
by support for international operations as well as a limited contribution from
domestic projects.

Acergy South America - The Acergy Condor and Acergy Harrier, on long term
contract to Petrobras, delivered improved margins from high levels of
utilisation throughout the quarter. The Pertinacia will become the third ship on
long term day rate contract to Petrobras in the second quarter of 2007. The
PRA-1 lump sum contract, our first of this type for Petrobras, progressed
towards the installation phase which is commencing during the first quarter of
2007 with the Acergy Discovery.

Acergy Asia and Middle East - Positive results on the Sakhalin projects were
partly offset by operational delays on the Dai Hung and Kerisi projects where
progress was slower than anticipated due partly to the knock on effect of the
North Sea divers' strike. The process of building up the infrastructure in Asia
to manage large deepwater projects gathered momentum throughout the year. This
made the breakeven target for the full year a real challenge, which was met
following successful resolution of a tax case. Contract tendering for the Sapura
3000 and Toisa Proteus remains very active.

Asset Development
The new build and conversion programmes on ships progressed throughout the
fourth quarter of 2006 against a backdrop of supplier delays and cost
escalations. The Pertinacia is expected to transit to Brazil to start her
contract with Petrobras in the second quarter of 2007. The Polar Queen, which is
now in the final part of her conversion, should be operational in the second
quarter of 2007. The Toisa Proteus and the Acergy Viking are also expected to
join the fleet in the second quarter and the Sapura 3000, in which we have a 50%
interest through our Sapura Acergy joint venture, is expected to be operational
in the third quarter of 2007. The Skandi Acergy is expected to join the fleet in
the second quarter of 2008.

Financial Review
Fourth Quarter
Net operating revenue from continuing operations for the fourth quarter of 2006
increased to $612.8 million from $463.4 million in the same period in 2005, due
to continued high activity levels in West Africa and the North Sea.

Net operating income from continuing operations for the fourth quarter was $72.6
million, compared to $56.6 million for the same period in 2005. The increase was
due to satisfactory project completion and higher utilisation of major assets.

Non-consolidated joint ventures contributed $3.5 million in the fourth quarter
as expected compared to $12.4 million for the equivalent quarter in 2005. This
was partly due to the Stanislav Yudin in the Seaway Heavy Lifting joint venture,
being in dry dock during the period and other project specific joint ventures
coming to an end.

Income from continuing operations was $74.2 million for the fourth quarter,
compared to $53.9 million in the same period in 2005. After including a loss
from discontinued operations of $6.2 million, net income from all operations for
the quarter ended November 30, 2006 was $68.0
<PAGE>
million. This compares to net income from all operations of $99.1 million for
the same period in 2005 after a gain of $45.2 million from discontinued
operations.

The cash and cash equivalents position at the quarter end was $717.5 million,
compared to $325.3 million at the quarter ended August 31, 2006. Total advance
billings at the quarter end was $234.8 million, compared to $265.3 million at
the quarter ended August 31, 2006. Due to the completion of the issue of the
Convertible Notes during the period, debt at quarter end was $509.5 million,
compared to $9.5 million at the quarter ended August 31, 2006. Capital
expenditure in the fourth quarter was $36.7 million.

FULL YEAR
Net operating revenue for the full year from continuing operations was $2,124.2
million, a 43% increase on net operating revenue from continuing operations of
$1,483.3 million for the full year 2005. The increase was driven mainly by the
significant growth in SURF activity in West Africa and the North Sea.

Net operating income from continuing operations for the full year was $286.7
million, compared to $152.0 million for the same period in 2005. The increase
was due to a higher level of activity and satisfactory project completion.

Non-consolidated joint ventures had a good year with a $41.3 million
contribution compared to $26.9 million for the full year in 2005, an improvement
broadly in line with consolidated activities. Seaway Heavy Lifting and NKT
Flexibles were the major contributors with project specific joint ventures all
performing well throughout the year.

Net income from discontinued operations was $15.8 million after a $35.1 million
gain on the sale of assets.

Under the share buyback programme initiated in September 2006, a total of
914,800 shares, representing 0.47% of issued shares, had been purchased as at
November 30, 2006. 4,849,700 shares, representing 2.49% of issued shares, had
been purchased as at February 12, 2007. These shares are held as Treasury shares
in addition to the 879,121 Common Shares held indirectly as ADR's also in
Treasury.

The Board have resolved to recommend the payment of a dividend of $0.20 per
share for 2007, subject to shareholder approval, at the annual general meeting.

CURRENT TRADING
The backlog for continuing operations as at November 30, 2006 was $2.6 billion,
of which approximately $1.7 billion is for execution throughout 2007. The group
also held an additional $301 million in pre-backlog at the quarter end.

In $ millions as at:    Nov.30.06     Aug.31.06     Nov.30.05
                       -----------   -----------   -----------
Backlog(1)                   2,587         2,618         2,194
Pre-Backlog(2)                 301           302           518

(1)  Backlog restated to exclude amounts related to discontinued operations in
     Acergy North America and Mexico of $11.2 million (November.30.06), $16.3
     million (August.31.06) and $23.5 million (November.30.05). Backlog reflects
     the stated value of signed contracts.

(2)  Pre-backlog reflects the stated value of signed letters of intent and the
     expected value of escalations on frame agreements.

OUTLOOK
Following rapid growth over the past two years and progressive improvements in
project execution, Acergy delivered solid results in 2006. The focus of the
group in 2007 will be to consolidate activities with the delivery of new ships
and the integration of new people. Our total quality management programme will
play an important part in this process, we believe, by laying the foundation for
a further improvement in our margin generation in future years.

The group therefore anticipates revenue growth of approximately 10% for 2007,
and we expect to return to a more rapid rate of growth thereafter. Backlog is
expected to grow particularly in
<PAGE>

West Africa, where the volume of bids outstanding at year end was 70% up on the
previous year, and in Asia where the level of bidding is three times the level
at this time last year.

The group now has market visibility through to 2012 with strong financial
resources to support growth. Management expects that the strong market
conditions that we have been experiencing over recent months will be maintained.
Acergy is on course to sustain its growth through the end of the decade with a
significant part of the project work for the next three years already at, or
close to, the bidding stage.
