Pollution Prevention 1978."

WALTER S. DIEHL

Avondale

The U.S. Navy fleet oiler Walter

S. Diehl (T-AO-193), the fifth in a series of 18 vessels of this type, was delivered in the third quarter by

Avondale Industries Inc.'s Ship- yards Division, New Orleans, La.

Built with the use of modern modular construction techniques, the Walter S. Diehl is 667-1/2 feet long with a beam of 97-1/2 feet, maximum draft of 36 feet and dis- placement of 42,000 long tons. Her main propulsion consists of two 10- cylinder PC4.2 Colt-Pielstick diesel engines manufactured by the Fair- banks Morse Engine Division of

Colt Industries, Inc.

Currently, these engines are the largest U.S.-manufactured medium- speed diesels capable of burning either DFM or heavy fuels of up to 3,500 sec Redwood at 100 degrees F.

The engines have a fuel rate of 136 grams/metric horsepower hour. The twin-screw design of the Walter S.

Diehl provides improved directional

December, 1988 stability, ease of control and mission reliability. The oiler is capable of speeds in excess of 20 knots.

The mission of the Walter S.

Diehl and other ships of the T-AO- 187 Class is to transport bulk prod- ucts and fuel from shore depots to combatants and support forces un- derway. The ships also deliver lim- ited fleet freight, cargo, water, lube oil, mail and personnel. The new ship has a cargo capacity of 183,500 barrels of oil in 18 cargo tanks and is capable of simultaneously receiving, storing and discharging two sepa- rate grades of cargo fuel. All cargo valve and pump operations and the ship's segregated ballast system are manipulated from the cargo control center located in the ship's aft su- perstructure, which has an overview of the entire underway replenish- ment is accomplished using transfer rigs with transfer hoses suspended by a span wire automatically main- tained in a constant-tension range.

The T-AO Class vessels are also capable of refueling helicopters from a vertical replenishment facili- ty aft of the accommodation house.

In late June of this year, Hyundai linking ports, coasts and continents by passenger ships and ferries

Passenger ships and ferries are connected with ports, coasts and continents by timetables that are accurate down to the last minute.

Under such circumstances the reliability of the propulsion plant takes on particular importance.

MAN B&W four-stroke Diesel engines have been proving their reliability either as straightforward

Diesel propulsion or Diesel-elec- tric propulsion plant on board famous cruise liners and ferries.

With its comprehensive engine programme and the lowest heavy fuel consumption rate ever reached, MAN B&W is able to supply the ideal propulsion concept for every ship.
