First Of 3 Rigs For Danish Firm Completed At Hitachi Zosen

A cantilever-type jackup offshore oil drilling rig, named Dan King, was recently completed at the Ariake Works of Hitachi Zosen for J.L. Offshore Drilling A/S, Denmark.

Dan King is the first of three identical rigs to be constructed by Hitachi Zosen for the Danish company. A member of the J. Lauritzen Group for shipping, J.L. Offshore Drilling specializes in offshore oil drilling; with the addition of Dan King, the company now has five drilling rigs.

The second rig for J.L. Offshore Drilling is scheduled to be completed in October 1981, and the third for Scout Shipping Co., Inc.

(also a member of the J. Lauritzen Group) in January 1982.

The Dan King (shown above) is designed for operation in water depths of up to 62.5 meters (205 feet) and can drill to a maximum depth of 6,096 meters (20,000 feet). It is also designed to permit connection of additional legs that can be extended for operation in waters 90.30 meters (296 feet) deep.

The rig ranks among the world's largest of its kind and is capable of operating under severe North Sea weather and sea conditions.

The spud tank is completely retractable within the platform. There is no projection from the bottom to facilitate towing in shallow waters or easy transportation by barge.

Hitachi Zosen has incorporated their long experience in both the marine and industrial fields in the original design of this highly advanced rig.

The Dan King's main specifications are: platform (L by B by D) 70 by 76 by 7 meters (230 by 249 by 23 feet) ; number of legs, three; overall leg length, 104.8 meters (344 feet) ; complement, 72; and classification, AB.
