McDermott Shipyard Lays Dredge Keel

Officials of McDermott Shipyard and American Dredging Company of Camden, N.J., recently cele- brated the keel-laying for a 294- foot, self-propelled, diesel-electric, split-hull hopper dredge at McDer- mott's Morgan City, La., yard.

Scheduled for completion by

March 1987, the trailing dredge, with a hopper capacity of 3,990 cub- ic yards, will be used to deepen, maintain, and improve waterways.

It will accommodate a crew of 21 and have an American Bureau of

Shipping Maltese Cross A-l Ocean

Going classification in addition to a

U.S. Coast Guard Ocean classifica- tion with unattended automated en- gine room. The vessel, which has a molded breadth of 54 feet and depth of 22 feet, can dredge to a depth of 70 feet and is equipped with under- water dredge pumps on the drag arms. Its gross tonnage is 2,746, with a lightship displacement of 2,400- tons and loaded displacement of 7,787 tons.

The 10,500-horsepower dredge is propelled by two 2,600-horsepower

Nigata Electric drives. Its six main

Caterpillar generators product 7,500 kilowatts of power. The vessel can carry 180,000 gallons of fuel and 27,000 gallons of fresh water.

American Dredging Company has been engaged for 119 years in the business of excavating solid materi- al in, out or through rivers, harbors and seas to deepen and maintain ship channels, create harbors, pro- vide fill for rights-of-way, take ca- bles and pipelines across rivers, har- bors and other bodies of water, restore and maintain beaches, dig canals, and drill, blast and remove subaqueous rock to improve chan- nels, harbors, coastal areas and ma- rine basins.

McDermott Shipyard, a division of McDermott Marine Construc- tion, specializes in the construction and repair of large tugs, supply boats, barges, dredges, and a wide variety of oceangoing work vessels.

McDermott Marine Cosntruction is a major operating unit of McDer- mott International, Inc., a leading energy services company. The com- pany and its subsidiaries provide worldwide engineering and con- struction services for industrial and commercial facilities onshore and to the oil and gas industry offshore.

They also manufacture steam gen- erating equipment, tubular prod- ucts, insulating products, and pro- cess control systems, and provide trading services for markets around the world.

Valmet Testing Newly Developed

Ducted Propeller For Icegoing Vessels

Valmet's Helsinki Shipyarc., as the culmation of a two-year research program, recently tested a new type of ducted propeller with the tug

Matari off the coast of Savonlinna.

The new type duct is said to be a new generation propulsion solution for Arctic vessels operating in ice.

As already known, a duct in- stalled around a propeller increases the total thrust by some 30 percent when the propeller is heavily loaded, as it is in ice conditions. At the same time, the duct protects the propeller from bigger ice loads. Un- til now, the problem has been that the duct gets blocked by large ice floes, and thus the use of ducted propellers has been very rare in spite of the obvious advantages.

As the result of two years of research, Valmet has now developed a patented ducted propeller that solves nearly all the problems re- lated to the blocking of the nozzle.

This new development will either increase the icebreaking capability of icegoing vessels or significantly decrease their fuel consumption.

The Valmet ice duct is suitable for all types of icegoing vessels, includ- ing icebreakers, cargo ships, etc. It
