Edison Chouest Offshore (Chouest) has formed a 30-month alliance with BP, extending a relationship that involves Chouest affiliates ECO, vessel services; C-Port, multi-service terminal facilities in Louisiana’s Port Fourchon; and C-Logistics, for logistics coordination, expediting and tracking cargo movement, a news release stated.

The agreement includes a three-year extension for utilization of BP’s Gulf of Mexico (GoM) Preservation and Maintenance facility, designed and built by Chouest, in Houma, La.

In addition, the vessel alliance includes a new 312-ft new generation, purpose-built platform supply vessel designed for delivery of supplies to BP’s GoM production platforms, ECO said in the release. The vessel is currently under construction at Chouest’s Houma shipyard, LaShip, and scheduled for delivery within the next several months.

Chouest and BP have had a business alliance for more than eight years.
