Oceangoing Split Hull Self-Propelled Dredge Completes Trials In Gulf The hopper dredge Manhattan Island, first split hull, self-pro- pelled hopper vessel built in the U.S., completed its sea trials re- cently, and was awarded certifi- cation by the American Bureau of Shipping and the U.S. Coast Guard. Initial trials were held in Lake Pontchartrain, La. Because of its unique design, additional trials were held in Gulfport, Miss. The purpose of the trials, which are required by the U.S. Coast Guard and ABS, is to put the ship through a series of tests for general seaworthiness and to evaluate her dredging capabili- ties, according to J.R. Gillespie, general manager of North Amer- ican Trailing Company which owns and operates the dredge. The demonstration of dredging capabilities was also observed by the U.S. Army Corps of Engi- neers. The North American Trailing Company is a subsidiary of Great Lakes Dredge & Dock Company of Chicago, with the participation of Amsterdam Ballast Dredging of Amstelveen, the Netherlands. Certificates of both ABS and the U.S. Coast Guard define the class of the ship and her load line. Because of U.S. Coast Guard certification, she will be regis- tered as a U.S. vessel for service in all oceans. The proper man- ning requirements are also stip- ulated. The ship will initially be em- ployed by NATCO on the Eastern Seaboard and Gulf Coast, work- ing on maintenance dredging and beach nourishment projects un- der the management of the U.S. Army Corps of Engineers. The board of directors recently authorized the construction of a second hopper dredge to the NA- TCO fleet, according to J.A. Downs, president. "The plans and specifications will be made avail- able to various shipyards within 30 days." Captain of the Manhattan Is- land is Leroy Piatt, who formerly served with the Marine Division of Bethlehem Steel Corporation. The Manhattan Island has a carrying capacity of 3,600 cubic yards, with a split hull made up of two longitudinal half sections hinged together at the deck. "The concept is almost 100 years old," according to Mr. Gil- lespie, "but this is the first time it has been incorporated into the design of an oceangoing self- propelled hopper dredge." The ship is 281 feet long, with a loaded draft of 19y2 feet and a light draft of 9% feet. The total installed horsepower is 6,750, op- erating for 14 days without re- fueling. It cruises at 12.5 knots light and 11.5 knots loaded, and has a capability of dredging to a depth of 70. feet. Great Lakes Dredge & Dock Company, the largest dredging contractor in the Western Hem- isphere and one of the largest in the world, is listed on the New York Stock Exchange. In addi- tion to the corporate headquar- ters in Chicago, 111., the company maintains offices on the Atlantic, Pacific and Gulf Coasts, as well as overseas offices in Argentina, Venezuela, Saudi Arabia and the United Arab Emirates.
