Western Gear Winch

Aids Pipeline Handling

During Stormy Seas

Development of an advanced- concept winch package which will allow pipelaying barge operators to manipulate tensioned pipelines during stormy periods at sea has been announced by Western Gear

Corporation.

The highly responsive and sen- sitive control mechanism is de- signed to increase safety of crew and equipment in hostile ocean environments.

Self-sensing and functioning in- tegrally with Western Gear's widely used Pipemaster pipe ten- sioners, the new abandonment and recovery (A & R) winch will be initially installed late this year aboard a new-generation pipelay barge.

The barge, one of the largest in the world, is designed for op- eration in the offshore petroleum production fields of the unpredict- able North Sea.

Designed to function despite heaving and pitching conditions, the A & R winch is used when- ever a lay barge is forced to in- terrupt the process of laying pipe on the sea bottom, a practice fol- lowed only during dangerous sea storms.

Under the unique Western Gear system, the winch operator gently transfers the highly tensioned pipeline from the pipe tensioner to the A & R winch. Then, the operator lowers the pipeline to the sea floor while the computer- ized control system maintains a closely regulated tension range throughout the operation.

The massive winch, with drum flanges 10 feet in diameter, is capable of spooling 4,200 feet of three-inch-diameter wire rope, and of producing a nominal full drum line pull of more than 300,000 pounds.

The A & R winch is being man- ufactured at Western Gear's plant at Everett, Wash., where the pro- prietary pipe tensioners and other products specially designed for the offshore and subsea mining industries are produced.

Among the other specialized equipment for petroleum produc- tion are motion compensation sys- tems for drilling rigs, riser and guideline tensioners, pipe rackers, and constant tension wiches.

Western Gear, with executive offices at Lynwood, Calif., is in the business of developing unique capital equipment and designs which will significantly improve productivity for major basic in- dustries.
