OSLO, Norway – STX Finland and Eide Marine Semi AS have signed a $413 million-plus contract under which STX will provide outfitting, completion, and delivery of two well intervention vessels.
These will each be 122 m (400 ft) long, 45 m (147 ft) wide, and with deadweight of 31,000 tons. Construction will start next spring at the Rauma shipyard in Finland, with delivery scheduled for March and June 2013.
They are designed to operate in rough open sea conditions on the Brazilian continental shelf.
The hull form, DP-3 dynamic positioning system, and thruster arrangement are designed for high sea-keeping characteristics. The large deck area, STX adds, should facilitate efficient layout of well serving equipment.
