Gotaverken Arendal

Delivers Offshore Rig

To Consafe Offshore

The SSV Safe Concordia, Gotaverken

Arendal newbuilding 911, was delivered re- cently to Consafe Offshore, Sweden. The off- shore rig has been chartered by Phillips

Petroleum and will operate at the Ekofisk

Field.

This is a large, twin-hulled, column-stabil- ized 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 Sup- porter are the first units in the world fully complying with the latest requirements of

NPD regarding accommodation offshore.

Each rig has accommodation for 600 persons in high-standard, two-bed cabins, each in- cluding shower and toilet.

Large recreation areas take care of the free time onboard: there are cinema, TV- rooms, library, conference rooms, and gym- nasium. In addition to the offshore personnel living onboard, the restaurant has capacity to serve additional people from other plat- forms.

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-
