Offshore staff

HOUSTON --McDermott International Inc. (NYSE: MDR) has been awarded a contract by Williams Partners L.P. (NYSE:WPZ) to transport and install a spar hull in the Gulf of Mexico.

McDermott will transport and install theGulfstar FPSGS-1 spar hull and moorings 150 mi (241 km) offshore in Mississippi Canyon in 4,200 ft (1,280 m) of water.

McDermott’s recently improvedDB50 vessel will install the moorings before transporting the classic-design spar hull to the installation site where it will be upended and ballasted before installing a temporary work deck. The offshore campaign is expected to begin in 3Q 2013.

McDermott says theDB50 is expected to deliver a greater reliability and versatility for subsea and platform completion projects since the installation of four new generators, six new thrusters, new DP controls, as well as a new active heave compensated deepwater lowering system mounted in the crane and designed for loads to a water depth of 11,000 ft (3,353 m).
