Gotaverken Arendal Delivers Offshore Rig To Consafe Offshore

The SSV Safe C o n c o r d i a , Gotaverken Arendal newbuilding 911, was delivered recently to Consafe Offshore, Sweden. The offshore rig has been chartered by Phillips Petroleum and will operate at the Ekofisk Field.

This is a large, twin-hulled, column-stabilized unit; it is the second accommodation and multi-service rig built at Gotaverken Arendal for Consafe Offshore. A sister rig, the Treasure Supporter, was delivered in March this year.

The Safe Concordia and Treasure Supporter are the first units in the world fully complying with the latest requirements of NPD r e g a r d i n g accommodation offshore. Each rig has accommodation for 600 persons in high-standard, two-bed cabins, each including shower and toilet.

Large recreation areas take care of the free time onboard: there are cinema, TVrooms, library, conference rooms, and gymnasium. In addition to the offshore personnel living onboard, the restaurant has capacity to serve additional people from other platforms. The cabins are partly built as a permanent deckhouse, partly as modules. The modulized accommodation is adapted for easy removal if a larger deck area should be required for construction or service duties.

Safe Concordia features a fully redundant dynamic positioning system including four 3,000-bhp azimuthing thrusters and two fixed 2,000-hp thrusters. Power is supplied by sev- en diesel generators with total output of about 18,000 hp.

These rigs have very much set the standard of offshore accommodation.

Currently under production at the Arendal yard are four jackup drilling rigs, two for Salen Energy, Sweden, and two for Protexa, Mexico. A semisubmersible drilling rig to be operated north of the 62nd parallel is under construction for Wilh. Wilhelmsen, Norway.
