Latest Breakthrough In Turret Moorings For FPS<

Systems: The Forgiving Tanker/Turret Interface

Ship-shaped vessels have seen a tremendous growth in their use as floating production and/or storage vessels. Along with this growth has come a need to moor in deeper water depths and with more flow lines. The most efficient means of dealing with the mooring of these vessels has been the incorpo- ration of a turret, which allows a vessel to weather- vane while providing a geostationary hull area and to bring in flow and mooring lines.

It is desirable to have turret systems weather- vane passively, which requires an efficient bearing system, particularly as many turrets are retrofitted into converted vessels. Interfacing these bearing systems with the turret and vessel structure requires extensive design and analysis to assure their mutual deformations will not affect the longevity of the bearing system.

A two bearing turret support system was designed and implemented as a result of this study.

The design is self-aligning by the incorporatior. spherical elastomeric suport in the turret/ves interface, maximizing the axial bearing capac available for carrying large verticals loads of det water, multiple riser systems. The interfa absorbs deformations, thus isolating the turret frc moonpool deformations and the moonpool from tu ret deformations, simplifying bearing design inte faces. A hydraulic grout alignment method elim nates the need for tedious shipyard machining ( bearing foundations and results in a short turret-tc vessel integration. All components in the turret sys tem reportedly lend themselves to standardizatioi and have been proven in the offshore environment.

Marine Drilling Wins Consortium Contract

Marine Drilling Co. Inc. shares rose 10.83 per- cent to 21-3/4 after the company announced it had been awarded a contract by a group of companies led by West Australian Petroleum Pty. Ltd. (WAPET). "The contract is currently projected to commence on or before January 1, 1999, and is expected to produce total revenues of $164 million to $188 mil- lion," the company said in a statement. Drilling will reportedly take place in the Pacific Rim,

Southeast Asia, and offshore Australia and New

Zealand. The day rate will be adjusted for each operating area to compensate for the respective expenses incurred in each area.

The company said its Marine 500 second-genera- tion semi-submersible will be upgraded for the con- tract to work in depths up to 5,000 fsw with 15,000 lbs. psi drilling equipment. These upgrades have been projected to cost between $70 and $80 million.

WAPET is the operator of a joint venture between Chevron Corp., Texaco Inc., Royal

Dutch/Shell and Mobil Corp.

Aker Maritime Introduces New Floating

Norwegian offshore services company Aker

Maritime ASA has developed a new type of floating platform especially suited to smaller fields which previously would have been considered uneconom- ic.

Aker said preliminary estimates showed that the platform, Buoyform, could be built in 23 months and at a cost of approximately NOK500 million less
