Edison Chouest Offshore (ECO) has announced that it will build 40 new vessels to meet growth in the offshore oil and gas support sector in the Gulf of Mexico, the Arctic and Brazil.
The company has started a new-build programme, comprising 17 new generation, clean design, diesel-electric platform supply vessels (PSV).
The new-build programme also includes an option for an additional 20 units of the same PSV.
Construction of the majority of the vessels will be carried out at the group's shipyards including North American Shipbuilding in Larose, Los Angles; LaShip in Houma; Gulf Ship in Gulfport, Mississippi and Tampa Ship in Tampa, Florida, as well as at Navship, its Brazilian shipyard.
In addition to complying with the new International Labour Organization (ILO) standards for vessel design and crew standards, the new class of PSVs also features a new hull form designed to increase deadweight as well as reduce hydrodynamic resistance for enhanced fuel efficiency.
The new 6,000dwt vessels will be capable of carrying over 22,000 barrels of liquid mud, over 2,000 barrels of methanol, 14,450ft³ of dry bulk and will be capable of accommodating 51 people.
ECO executive vice president Dino Chouest said the company owns and operates the largest fleet of new generation, high deadweight capacity PSVs in the global offshore service vessel industry.
"The new series of 312' PSVs under construction represents an evolution of ECO's proven proprietary hull designs," Chouest said. "The 312' class meets 100% of ECO's customers' requirements for a high deadweight ton capacity, deepwater PSV that is extremely fuel efficient."
The company will also be responsible for building two ice-class anchor handling tug supply (AHTS) vessels for Arctic service as well as four subsea construction vessels, slated for service in the Gulf of Mexico market.
The new-build programme also includes seven fast-supply vessels, five 304ft Polish-built PSVs, as well as two 316ft anchor-handlers and five 303ft PSVs for the Brazilian market.
As part of the expansion, ECO has also started work on a fourth C-Port facility at the Port Fourchon supply hub in south Louisiana, as well as design work for comparable facilities in Brazil.
