Bender To Construct Two

Jackup Vessels For Work

In Gulf Of Mexico

Bender Shipbuilding & Repair

Co., Inc. of Mobile, Ala., has re- ceived an order from Nolty J. Ter- iot, Inc. of Golden Meadow, La., for two 175-foot class self-elevating workboats designed for mainte- nance of offshore production plat- forms.

The order calls for the first vessel to be completed by midyear 1991, and the second vessel by late sum- mer.

The self-elevating workboats, commonly called jackup vessels, will be used for maintenance work on production platforms in the Gulf of

Mexico. In these maintenance pro- grams, the vessels are positioned be- side the platform and can jack up next to it for repairs and mainte- nance.

Powered by Caterpillar engines, the vessels are being designed to work in waters in excess of 100 feet and will be equipped with one 60- ton crane and one 15-ton crane.

Bender Shipbuilding was also re- cently awarded a $350,000 contract for the topside repair and modifica- tion of the USNS Lynch (AGOR-7).

The Lynch is a 207-foot-long ocea- nographic research vessel operated by MAR Ship Operators, Rockville,

Md., for the U.S. Navy.

Air-Independent Mini-Sub

Designed By Thyssen

Thyssen Nordseewerke GmbH of

Germany has designed a new sub- marine capable of extended under- water endurance using a closed- cycle diesel engine.

The 98.4-foot-long by 18.7-foot- beam mini-sub, dubbed the TR-300, would displace 300 tons submerged and carry a crew of eight sailors.The dimensions give a 5:1 length-to- beam ratio which is traditional in modern German submarines.

The design would use a closed- cycle diesel running on oxygen drawn from a cryogenic tank.

Thyssen is known to have signed an agreement with Cosworth Deep Sea

Systems of Britain to use its pat- ented gas management system.

The Cosworth system eliminates exhaust compressors which in the past limited the depth a submarine could operate with a closed-cycle diesel.

The TR-300 would have only a 45-nautical-mile (nm) range when running submerged on batteries, but a 2,000-nm submerged range when running on closed-cycle die- sel.
