Nippon Kokan To Build

Semi-Submersible Rig

For Norwegian Firm

Nippon Kokan (NKK), Tokyo,

Japan, is building an "Ultra Yatzy" semi-submersible offshore drilling rig for the Norwegian Dyvi Group.

The construction is expected to be completed in May 1986.

The "Ultra Yatzy" will have a maximum deck load capacity of 4,500 tons and a maximum drilling depth of 2,300 feet. It will be able to operate in severe deep-sea condi- tions.

The semi-submersible offshore rig is larger than the original Yatzy- type, for which NKK concluded a technical license agreement in 1983 with Dyvi Engineering A/S. The new contract is covered by a "spot" license.

The rig, which will be operated in the North Sea, will be owned by an international consortium formed by the Dyvi Group and several other firms with actual operation man- aged by Dyvi Offshore A/S.

The main deck area of the rig will be 66 meters (216.5 feet) by 70 meters (229.6 feet). The living quar- ters will accommodate 90.
