$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. E. Canadian Section Meets In Montreal Shown at the Eastern Canadian Section meeting, left to right: Monroe D. Macpher- son, chairman of the Committee on Sec- tions; R.C. Truax, Section chairman; Phil- lip Eisenberg, national president of SNAME, and Robert G. Mende, national secretary of SNAME. The Eastern Canadian Section of The Society of Naval Architects and Marine Engineers 'held its an- nual general meeting in Montreal, Canada, on April 24. Phillip Eisenberg, national presi- dent of SNAME, elected to visit the Section at this time, accom- panied by Robert G. Mende, na- tional secretary, and Monroe D. Macpherson, chairman of the Com- mittee on Sections. The retiring chairman of the Eastern Canadian Section, R.C. Truax, was presented with the So- ciety's Certificate of Appreciation by Mr. Eisenberg. Gordon German was elected chairman for the 1973-74 season. Following the business portion of the meeting, Paul Preville, vice president-steamships, Clarke Transportation Canada Ltd., pre- sented a most interesting paper titled "A Canadian Experience in Containerization." In the paper, Mr. Preville dis- cussed the operation and manage- ment of containerization and high- lighted the many problems en- countered. A color film was viewed as part of the presentation, begin- ning with the building of a con- tainership, to the eventual unload- ing at its destination. Author Poui A.
