Edison Chouest Offshore (ECO) has long been the leading offshore service vessel company in the Gulf of Mexico with more than 100 vessels offering supply, crew transportation, anchor handling and other services. Last year the company debuted the world's largest OSV, the 348-ft. Laney Chouest, an Anchor Handling Tug Supply (AHTS) vessel and the continuation of their 280-ft. series of supply vessels. By the end of this year, six of the 280-ft. vessels will have been built. Now the Galliano, La.-based company is looking to extend its reach internationally and has formed a new company, Island Offshore Shopping AS, to pursue offshore service business internationally. Island Offshore is a joint venture between Edison Chouest Offshore and Ulstein.
