Mar A d Awards Cooperative Research Contract To Seaworthy

The Maritime Administration has awarded a $342,500 contract to Seaworthy Engine Systems, Inc., Essex, Conn., as part of a cooperative research project to evaluate the benefits of applying exotic ceramic and metallic coatings to combustion system components of high-speed marine diesels.

The company will install and, according to a schedule, remove combustion system components being tested. It also will analyze and evaluate engine performance.

Two towboat owners and operators, Ohio Barge Lines, Inc., of Dravosburg, Pa., and Ingram Barge Company of Nashville, Tenn., are cooperating in the project, as is the Electro-Motive Division of the General Motors Corp. of La Grange, 111.

Coatings will be selected, applied and evaluated by the Lawrence Berkeley Laboratory of the University of California under the supervision of the Department of Energy.

Under each of the two phases of the project, coated combustion system components (valves, pistons, heads, rings and turbo-chargers) will be installed in two high-speed diesel engines. The coated components will be left in one engine for about 6,000 hours; selected components will be removed from the other at about 500-hour intervals.

In the first phase, to be completed in April 1985, the engines will operate on No. 2 marine diesel fuel. During the second phase, to be completed a year later, offspecification and blended fuels will be used.
