GIBRALTARGibdock has completed a 19-day refit of the seismic vesselWG Cook for WesternGeco.

This was one of six 12-streamer 3D seismic ships delivered to the contractor in 2010.

The vessel was allocated at Gibdock’s largest dry dock, to allow simultaneous deployment of a variety of yard equipment. One of the dock’s three cranes was occupied continuously by a 5-m (16.4-ft) exhaust extension and main mast modifications.

Work included replacement of the ship’s thruster z-drives, box cooler removal, sea chest modification, hull blasting, and painting.

Among the more intricate tasks were the upgrade and modification ofWG Cook’s hydraulic pipes on two decks, and modification of hydraulic lines following equipment relocation.

About 300 personnel were onboard the vessel during the project’s peak period.
