WG Cook in for refit at Gibdock

Gibdock completed a refit of the seismic vessel WG Cook for WesternGeco. WG Cook is one of six 12-streamer 3D seismic ships delivered to the owner in 2010. The 19-day project was completed on time and with no serious QHSE incidents in preparation for WG Cook’s deployment offshore Canada for a seismic survey.

Gibdock allocated its largest drydock to the project, allowing a variety of yard equipment to be deployed simultaneously. The dock’s heavy lifting capability was also a factor, with one of its three cranes being occupied continuously by a 5m exhaust extension and main mast modifications. Docking repairs also included the replacement of the ship’s thruster z-drives, box cooler removal, sea chest modification, hull blasting and painting.

Particularly demanding was upgrade and modification of WG Cook’s hydraulic pipes on two decks, and modification of hydraulic lines after equipment relocation. The WG Cook project included work on hydraulics, so skills available in this trade were a particular focus, with close coordination between the ship's owner, the yard and the yard’s subcontractors.

“Around 300 personnel from the yard and the owner were onboard the vessel during the project’s peak period,” said Richard Beards, Gibdock Managing Director. “Coordinating work so that completing one job did not interfere with another was a critical factor in redelivering WG Cook on schedule and with no serious QHSE incidents.”
