Demag Cranes Make Superlift

At Canadian Vito Shipyard

The Vito Steel Boat & Barge Construction shipyard in Canada recently delivered a 230-foot auxiliary navigation and supply vessel to the

Canadian Coast Guard. Economy considerations prompted the company to use a new approach to the assembly of the vessel. The complete super- structure, including the deck, was pre-assem- bled on the ground.

The shipyard used two Demag TC 2000 truck- mounted cranes (photo) to place the 500-ton superstructure onto the 35-foot-high hull. They first lifted the heavy load off the ground, rolled the hull under the superstructure, then did the precision lowering of the superstructure and joining of the assemblies. This method permit- ted the construction time to be reduced dramat- ically.

STRETCHING ITS 607-FOOT LEGS—A massive offshore jackup drilling rig, the Rowan

Gorilla III, towers 437 feet above the surface of the water after its three steel legs had been extended an additional 100 feet. With its 607- foot tall legs, the Gorilla III is capable of drilling in water 450-feet deep in the Gulf of Mexico.

The leg extension project was recently per- formed in an outfitting basin near Pascagoula,

Miss., by 80 workers from Marathon LeTour- neau's Vicksburg, Miss, rig yard.

American Metal Bearing's

Rubber Bearing Staves Approved

By Navy—Literature Offered

Large ship's propeller-shaft bearing with American Metal

Bearing's all-rubber staves lining the inner surface.

All-rubber bearing staves designed and pro- duced by American Metal Bearing Co. of Gar- den Grove, Calif., have been approved for use on

U.S. Navy ships to replace other rubber and brass staves supporting propeller shafts.

The approval was announced by Peter A.

Pagan, vice president and director of market- ing for the 64-year-old marine equipment manu- facturer.

AMB's staves will fit bearings with propeller shaft diameters of 6 to 36 inches. Grooves between the staves allow water to be channeled through the bearing for lubrication and to carry away sand and other abrasives.

American Metal Bearing's all-rubber staves utilize dual-hardness, low-friction nitrile rub- ber. The bearing surface is tough, but resilient, allowing abrasive particles to depress it rather than penetrating the bearing surface. This rub- ber is bonded to an even harder rubber backing, which takes the place of brass.

According to Mr. Pagan, the all-rubber stave has several advantages over older style staves, including: the hard rubber backing will not sep- arate from the softer rubber bearing surface; easier to install; it weighs less; and cost savings.

The company's primary business is the de- sign, manufacture, and repair of individual bear- ings and complete bearing systems for naval and commercial vessels, as well as a variety of uses in cement, petrochemical, rubber, steel, utilities, and heavy machinery industries.

Brochure Explains New USCG

Survival Suit Regulations

Survival International, Inc. has produced a new brochure that fully explains current U.S.

Coast Guard regulations concerning use of sur- vival suits.

Unlike some federal regulations published in the "Federal Register," this booklet is written in laymen terms—easy-to-understand language— and fully explains previous regulations and new laws inacted in December 1985 concerning who must carry survival suits aboard their vessels and why.

For example: Did you know the latest regula- tions require that your vessel carry two survival suits aboard for most crew members? Did you know that the latitude has been changed from 35 degrees to 32 degrees, meaning that if your vessel operates in these waters it must have sur- vival suits on board.

Do you know if your vessels are required to carry such safety equipment? What type of sur- vival suits are allowed under the law? Can you replace PFDs with survival suits?

These and many more questions are answered in this highly informative booklet. For your free copy,
