Acergy was founded in 1970 under the name Stolt Nielsen Seaway as part of the Stolt-Nielsen shipping company in Haugesund (Norway) and in the early 1970s offered diving vehicles and divers for exploring the North Sea . In 1989 the company expanded to Aberdeen (United Kingdom) and in 1992 acquired Comex Services , a French diving and construction company. The company expanded further in the 1990s and currently has locations in Stavanger (Norway), Aberdeen (United Kingdom), Suresnes Cedex, ( France ), Houston (United States), Rio de Janeiro (Brazil) and Singapore .

In 1997, the company won its first major deep-sea contract on the coast of West Africa , which was followed by the acquisition of Ceanic Corporation (Houston, USA) and the French pipeline technology specialist ETPM. They also took over 49% of the Danish company NKT Flexibles .

In 2000 the company name (company) changed to Stolt Offshore , but the rapid expansion and poor project management resulted in greater losses. In 2003 a new management team started a reorganization. In 2005, the parent company sold the company, which then went public. On March 1, 2006 the company switched to Acergy.
