Hitachi To Build Third Jackup Rig For Danish J.L Offshore Drilling

Hitachi Zosen recently received an order for construction of another cantilever type, jackup offshore oil drilling rig for J.L. Offshore Drilling A/S, Copenhagen.

This is the third rig of this type to be ordered from Hitachi by J.L. Offshore. All three rigs are designed for operation under rough sea and severe weather conditions. The first is scheduled for delivery on July 1, 1981, the second on October 1, 1981, and this latest one in January 1982.

The rig is designed for operation in water depths under severe North Sea weather conditions of up to 62.5 meters (205 feet) and in water depths of less severe weather conditions of up to 91.8 meters (301 feet). It ranks among the world's largest of this kind, a cantilever type. Hitachi has drawn upon its long and extensive experience in both marine and industrial fields in the design and construction of this highly advanced rig.

Hull dimensions are 70 by 76 by 7 meters. The three legs have an overall length of 104.8 meters (343 feet), and can be extended up to 129.5 meters (425 feet).

The rig will be built at Hitachi's Ariake Works to American Bureau of Shipping Classification. It will have a complement of 72 persons, and drilling capability of 6,096 meters (20,000 feet).
