Pecunia, president of Peterson Maritime Services, Inc., in New Orleans. Before joining Peter- son, Mr. Benson served with the United States Coast Guard's Gulf Strike Team, National Strike Force, and as Coast Guard Captain of the Ports of New Orleans and Honolulu. Peterson Maritime Services has offices in New Orleans, Houston, and Mobile. Other divisions of the company include ship and barge cleaning, aviation, oil pollution, and sales and marketing. Most recently, Peter- son Maritime successfully handled the world's largest waterborne pentachlorophe- nol spill in the Mississippi River Gulf Outlet between New Orleans and the Gulf of Mexico. Two Detroit-Powered Tugboats Completed By Manly Shipyards John Manly Shipyards, a division of Riv- Tow Shipyards Ltd., recently delivered two tugboats to RivTow Straits Ltd., the second largest towing company in British Colum- bia, Canada. The new vessels have joined RivTow's fleet of 75 tugs, 175 barges, and 75 small boom boats. Tugboats RivTow Spirit and Westminster Chinook were delivered recently by John Manly Shipyards of Vancou- ver, B.C., to RivTow Straits Ltd., Vancouver, second largest towing company in British Columbia, Canada. The RivTow Spirit is a 64-foot 9-inch shallow-draft tug to be used at the Port of Prince Rupert. The Mclllwain-designed tug has a beam of 24 feet, a river draft of 8 feet, and an ocean draft of 9 feet 4 inches. She is powered by two Detroit Diesel 16V71 engines, each producing 490 bhp at 1,800 rpm, driving twin Western propellers in Kort nozzles through Twin Disc 567 reduction gears. The Westminster Chinook is a 53-foot ship-docking and barge-handling vessel to be used in the Port of New Westminster. She has a molded beam of 23 feet 6 inches and a draft of 10 feet 9 inches. Her power pack- age is identical to the RivTow Spirit. Both vessels comply with all applicable Canadian Steamship Inspection requirements and with Workers' Compensation Board reg- ulations. Both have extensive sound-damp- ening and vibration-reducing systems pro- viding very comfortable decibel levels. Most interesting is the sound and vibration re- duction achieved in the Chinook's wheel- house by isolating the entire structure on pedestal mounts. Steering systems for both vessels was provided by Wagner; electrical power is sup- plied by Detroit Diesel 4-71 generators. All closures are standard Manly windows, doors, and hatches. Life rafts are by Beaufort. Derrick/Supply Vessel Now In Gulf Service For Tidewater Courtney A. Benson William L. Thomas Courtney A.

Refitted with a new Amer- ican Hoist & Derrick, Model 9760, 90-ton lifting capacity, pedestal-mounted crane, the vessel is certified by the U.S. Coast Guard for unrestricted ocean service. The Lift Tide is 186 feet by 56 feet by 14 feet 6 inches, can operate at a minimum wa- ter depth of 16 feet, and offers mobility with moderate lift capacity. Powered by two 16- cylinder GM Electro-Motive Division engines that develop 3,600 bhp, the vessel has a top speed of 12 knots. Equipped with a new four-point mooring system pioneered by Tidewater Marine Serv- ice, Inc., the vessel is highly stable in the working mode. The system provides four 10,000-pound anchors, with each anchor sup- plied with 3,000 feet of 114-inch steel cable. The anchors are lowered and retrieved by two new double-drum SMATCO DAW 55 winches mounted on the main deck. The Lift Tide crew consists of seven per- sonnel and a 10-member work force that in- cludes a barge superintendent, crane oper- ator, winch operator, foreman, welder, and five riggers. Additional personnel such as divers, diving tenders, pipeline inspectors, X-ray technicians, ultrasonic technicians, and other specialists can be added as re- quired, as the vessel is designed to provide total accommodations for 34 persons. Tidewater Contractors operates four other four-point mooring specialty vessels in the Gulf of Mexico in addition to the Lift Tide. An affiliated company, Tidewater Marine Service, Inc., one of the Tidewater Inc. group of companies, owns and operates a fleet of approximately 400 vessels in oil and gas producing areas around the world, and is the world's largest supplier of marine support equipment to the offshore drilling industry.
