MarAd Releases 15 Technical Reports

On Gas Turbines

The Maritime Administration has released a group of 15 tech- nical reports evaluating the feasi- bility of heavy-duty gas turbines as a competitive and acceptable form of marine propulsion gen- eration. The reports were pre- pared under a contract awarded in 1970 to the General Electric

Company, Gas Turbine Products

Division, Schenectady, N.Y.

The total technical effort was completed in a period of five years and at a total cost of $8,025,000, which was shared equally by General Electric and

MarAd. The project encompassed a wide range of research and de- velopment activities, including: research on fuel additives, tur- bine blade coating and cladding materials, turbine cleaning tech- niques and fuel oil washing; and design, development and testing of an RF Plasma Fuel Oil Ana- lyzer, internally reversing gas turbine and regenerators having improved materials and cyclic life.

The objective of the project was to pursue those design and development efforts that would permit the "marinization" of the heavy-duty gas turbine. Basically, this implied that the "marine" heavy-duty gas turbine must be capable of burning typical marine residual fuels having high sulfur, vandium and sodium levels; ca- pable of developing the required astern power for maneuvering; competitive with other forms of power generation (primarily steam turbine) from both a fuel consumption and maintenance point of view.

The reports are available from the National Technical Informa- tion Service, 5285 Port Royal

Road, Springfield, Va. 22161. The following is a list of the re- ports, including price and order numbers:
