$2.4-Million Order

For Pipe Tensioners

To Western Gear Corp.

Western Gear Corporation, Lyn- wood, Calif., has received orders valued at approximately $2.4 million from J. Ray McDermott & Company,

New Orleans, La., for three auto- matic pipe tensioning systems to be installed aboard three McDermott lay barges on projects for the world- wide offshore construction industry.

The proprietary pipe tensioners are of the wheel-type of an advanced design and similar to more than a dozen of the machines previously fur- nished McDermott by Western Gear's

Heavy Machinery Division in Ever- ett, Wash.

McDermott has ordered the pipe tensioners, each barge-set with a 108,000-pound tension capacity, for its existing Lay Barge 25 off Singa- pore, and for the Lay Barges 27 and 28 under construction in Japan.

Each barge, of the center-slot type, will have two pipe tensioners working in tandem, six in all for the total order. Deliveries in Singapore and in Japan are scheduled for mid-1973.

The Western Gear pipe tensioners handle pipe up to 40 inches in diame- ter, and are 28 feet long, 13 feet wide, and 14 feet high, weighing approxi- mately 122,000 pounds each, and ca- pable of hauling in and paying out pipe at speeds up to 85 fpm. The lengths of heavy pipe, welded into a pipeline aboard the barges, are con- trolled by the massive tensioning ma- chines as the line moves off the stinger of a catenary toward final placement on the ocean floor.

Prime power for the machinery for the two barges (each 410 feet long and 120 feet wide) under construction will be provided by two electro-hy- draulic power units of 200 hp each, from a below-deck station. Cummins

Diesel-hydraulic power units will pro- vide backup power. The Lay Barge 25 system will have three Detroit

Diesel-hydraulic power units provid- ing power for the tensioners. Western

Gear electronic sensing controls with hydraulic backup controls, will pro- vide highly reliable, automatic ten- sioning on the extensive equipment.
