McDermott Gets $48-Million

Offshore Contract From

Chinese Petroleum Corporation

McDermott International, Inc. has been awarded a contract worth approximately $48-million by the

Chinese Petroleum Corporation of the Republic of China. The turnkey contract involves engineering, pro- curement, and construction of one drilling and production platform, two wellhead platforms, installation of four subsea wellheads, five plat- form completion wellheads, and lay- ing 40 miles of pipelines in the CBK oil and gas field, 15 miles northwest of Hsin Chu, Taiwan, Republic of

China.

The platforms, all four-legged, and subsea wellheads will be in- stalled in water depths of approxi- mately 200 feet. Fabrication will be- gin this month and is scheduled to be completed in July. The projected production rates for the field are 56 million cubic feet of gas and 10,000 barrels of oil per day.

The offshore pipelines to be laid include 15 miles of 12-inch gas lines, 15 miles of 6-inch oil lines, 4.5 miles of 8-inch flowlines, and 5.5. miles of 6-inch flowlines.

McDermott's combination der- rick/lay barge DB-29 will be the pri- mary piece of marine construction equipment used on the offshore por- tion of the project, which is sched- uled to begin in May and be com- pleted by August.

Bardex Hydranautics Island

Rig Skidding System

Pool Arctic Alaska Anchorage has contracted with Bardex Hydranau- tics for a rig skidding system which

Pool Arctic Alaska will use for Sohio on the Endicot artificial island pro- ject in the Beaufort Sea. The system will perform transverse rig skidding over the wellheads on an Arctic wheel-mounted rig and will be re- quired to operate in —60 degrees F conditions. The rig is skidded back onto the wheels for proper road bal- ance.

The order comes on the 20th an- niversary of the first use of such equipment on a major man-made island project—THUMS off Los

Angeles. Bardex Hydranautics sup- plied the system, which is still in operatin there, that skids the der- rick, triple-deck sub-base and cas-

Keel-laying ceremonies were held recently for the second of three con- tainerships being built for Sea-Land

Service, Inc. by Bay Shipbuilding

Corp. The laying of the keel of Hull

No. 736 took place in Bay's large graving dock where all three vessels will be constructed. Each container- ship will be 710 feet in length, 78 feet in beam and have a design draft of 30 feet.

Sea-Land Service, Inc., a subsid- iary of Sea-Land Corporation, will operate the three fuel-efficient die- sel-powered containerships between the Pacific Northwest and Alaska.

The 20-knot vessels, each capable of carrying over 700 containers, will significantly increase Sea-Land's cargo-carrying capacity in the Alas- ka trade.

The keel for the first container- ship, designated Bay Shipbuilding

Hull No. 735, was laid in August of 1985.

Bardex Hydranautics is head- quartered in Goleta, Calif., with of- fices in London, Singapore, and

Houston. The company designs and manufactures heavy-load moving equiment for offshore and shipyard- related activities.

Omnithrusters Delivered For

Canadian Government Vessels

Omnithruster Canada Inc. of Sar- nia, Ontario, a subsidiary of Omni- thruster Inc. of Santa Fe Springs,

Calif., in recent months has deliv- ered four units for installation in

Canadian government vessels.

The John P. Tulley, a 226-foot hydrographic survey vessel owned by the Canadian Department of

Fisheries and Oceans, is fitted with an Omnithruster JT 8001 500-hp horizontal unit forward and a JT 700 350-hp unit aft.

The CCGS Narwhal, built by Ca- nadian Vickers (now Versatile Vick- ers of Montreal) in 1963, is undergo- ing a complete refit at Halifax In- dustries. A full machinery upgrad- ing includes an Omnithruster PV 700 unit.

The new Canadian Coast Guard

Type 1050 navaids tender/light ice- breaker being built at the Nova Sco- tia shipyard of Pictou Industries, a division of USL International, is be- ing fitted with an Omnithruster JT 950 unit manufactured in Sarnia.

Reliance Electric of Stratford, On- tario supplied the 750-hp motor for this unit, and Byron Jackson of

Hamilton the pump.

Basically, the Omnithruster hy- drojet unit consists of a protected intake in the bottom of the hull leading to a low-pressure, high-vol- ume pump. This in turn delivers water through high-pressure direc- tional nozzles in the ship's side. The low location of the intake is unaf- fected by the vessel's trim, and the relatively low velocity of the intake is less affected than conventional thrusters by the ship's speed in rela- tion to the surrounding water. The action of the thruster being against the ship and not the outside water means that it operates efficiently whether submerged or not.

Changes in direction of thrust from port to starboard are activated by valves controlling the flow of water, not by reversing the motors.

This greatly reduces vibration and noise potential. A bonus is that out- flow, even without air injection that can be induced, can be used as hull lubrication for navigation in ice.
