Acergy and Subsea 7 Receive Anti-Trust Clearance

Two of the world’s most respected subsea oil field construction companies, Subsea 7 and Acergy will be formally merging next year.  This merger will end the bitter head-hunting and bidding wars that have ensued over the past few years between these two companies.

Their main deepwater competitors include Technip and Aker Solutions, both operating state-of-the-art subsea construction vessels such as the ultradeepwater-proven Deep Blue and the luxuriously appointed Boa Sub C, respectively.

US Federal Trade Commission and the Anti-trust Division of the US Department of Justice. On
