NKK To Build Floating Offshore Production Unit For Norwegian Consortium

A Norwegian shipowners' consortium, K/S Petrojarl I A/S, has awarded Nippon Kokan (NKK) of Japan a contract to build a deepwater, offshore oil production and testing system. "It will be the first floating production unit built to serve a variety of offshore applications, in contrast with units commissioned directly by offshore operators for a specific field development," according to Minoru Hashimoto, president of NKK America Inc. of New York, the company's U.S. subsidiary. "The unit can operate in the early stages of a new field and provide immediate cash flow for the operator prior to the installation of a fixed facility," he added.

The contract stipulates completion of the 695-foot-long production and testing system (PTS) at the beginning of 1986. Construction will take place at NKK's Tsurumi Shipyard.

Capable of first-stage processing of up to 20,000 barrels per day through a riser pipe linking the system and the oil field, the PTS will operate at water depths between 330 and 2,130 feet. It will have a storage capacity of 160,000 barrels of oil, which will be transferred to onshore terminals at regular intervals by shuttle tankers. The unit will be operated by Golar-Nor Offshore, a subsidiary of Det Nordenfjeldske Dampskibsselskab (NFDS), a member of the consortium. The PTS is designed to be positioned above an oil field using a dynamic positioning system combined with a turret mooring system.
