Comex was a french company, became Comex Seaway, and was later eaten by Stolt. Now its part of Acergy.
From the Wikipedia encyclopedia:
The company started as the Haugesund based Stolt Nielsen Seaway and offered divers for the exploration of the North Sea in 1970. The company was part of the Stolt-Nielsen Group. In 1989 the company expanded to Aberdeen, United Kingdom and in 1992 the company acquired the French diving company Comex Services. In 1997 the company won its first ultra-deepwater contract off West Africa, resulting in the acquisition of Houston based Ceanic Corporation, Danish NKT Flexibles and ETPM of France.
In 2000 the company changed its name to Stolt Offshore. But poor management forced the company to narrow its focus and a new management was introduced in 2003. In 2005 the Stolt-Nielsen Group sold its ownership in the company and listed it on the Oslo Stock Exchange and NASDAQ. As of March 1, 2006 the company changed its name to Acergy.
