Frank Silliman Board Chairman

Frank P. Silliman

Bernard T. Kelley has been elected presi- dent of Hillman Barge & Construction Co.,

Hillman Transportation Co., and Silliman

Towing Co.

Mr. Kelley succeeds Frank P. Silliman, who has been elected chairman of the board and will continue as chief executive officer of the three companies. Mr. Silliman has been presi- dent of Hillman Barge since 1950, Hillman

Transportation since 1960 and Silliman Tow- ing since 1954.

Mr. Kelley has been with the Hillman com- panies for his entire business career of more than 25 years, most recently, as vice president and general manager and director of Hillman

Barge and vice president of Hillman Trans- portation.

A native of Brownsville, Pa., Mr. Kelley received a degree in engineering from Mar- quette University, Milwaukee, Wis., in 1946.

Hillman Barge & Construction Co., Hillman

Transportation Co., and Silliman Towing Co. are subsidiaries of The Hillman Company of

Thrige-Nakskov Receives

Deck Machinery Contracts

Totaling Over $3-Million

Thrige-Nakskov Machine Works Ltd., the Dan- ish marine engineering company, has announced that large contracts, both domestic and for export, have been signed recently. The value of the con- tracts exceeds three million dollars and includes steam-driven deck machinery for 16 supertank- ers to be built in Denmark and Italy. Esso, Shell and A.P. Moller are among the shipowners.

The current order book will result in further expansion of the recently founded company, which was a result of a merger between the deck ma- chinery divisions of the two Danish companies

Thrige-Titan and Nakskov Shipyard.

In addition to steam-driven deck machinery for all sizes of tankers, the manufacturing program of the company includes electrically and hydrauli- cally powered deck machinery, remote-controlled valves and container spreaders.

Thrige-Nakskov's U.S. representative for sales and service is Stal-Laval, Inc., 400 Executive

Boulevard, Elmsford, N.Y. 10523.

Stork-Werkspoor Diesels

Run On High-Viscosity Fuels

Several years ago the Stork-Werkspoor diesel engine designers designed an in-line and a V- form, medium-speed engine to run on heavy fuels with a viscosity of 500 up to 3,500 sec. Redwood

I at 100°F., with an average sulfur content of over three percent and average vanadium con- tent of about 100 ppm. The engineers based the design on the wide experience the firm had with trunk-type piston engines already running on high viscosity fuels.

The features incorporated in this design were: 1. A low-pressure recirculating fuel-oil system to keep the fuel pumps at a constant temperature; 2. Effective cooling and heating of the injector nozzles by means of a separate cooling-water sys- tem, to prevent carboning and corrosion attack of injectors; 3. Deeply water-cooled exhaust-valve cages to reduce the exhaust-valve temperature. The seats of the exhaust valve and valve cage were stellited. 4. Separate impulse lubricating-oil system for the valve gear and valve stems. The waste oil and any water or fuel that might leak into the cylinder head is drained into a drain tank and thus prevents deterioration of the oil in the sump, and 5. Extremely large inlet and exhaust valves to reduce the exhaust-gas temperature in order to prevent the attack of vanadium-sodium compo- nents on the turbo-charger blades.

The tests of this design, known as TM 410, proved very satisfactory.

The first engines running on heavy fuels were installed in the ocean-going tug Rode Zee of Srnit and Company International Towing Service.

These engines were placed in service about three years ago and have run over 15,000 hours. In- spections made periodically of these engines have confirmed the test-bed results. Due to these serv- ice results, the inspection intervals for the exhaust valves have been increased to 5,000 hours and the injectors to 3,000 hours.

At present, about 45 TM-410 medium-speed diesels, developing at full load 667 bhp/cylinder at 550 rpm, are operating on high-viscosity fuels.

This engine is being distributed in the United

States by Oosterhuis Industries, Inc., P.O. Box 30587, New Orleans, La. 70130, and by Ooster- huis Associates, Inc., 1025 Vermont Avenue,

N.W., Washington, D.C. 20005.
