Naval Propulsion Systems (continued) ing power. GMT engines have also been used for cruise propulsion in

Italian Maestrale Class frigates and

Animoso Class destroyers.

Sulzer Brothers engines are on a wide variety of naval auxiliary ves- sels and research ships. For exam- ple, Argentina's naval auxiliary ves- sel Cabo San Antonio is equipped with four Sulzer 6ZH40 diesel en- gines.

Additionally, 5RTA76 series en- gines with PTO were installed on the 615-foot T-5 tankers built by

Tampa Shipyards.

Bombardier Inc. of Montreal, which purchased Alco Power Inc. in 1984, supplied 42 Paxman Valenta engines to Bollinger Machine Shop & Shipyard Inc., for installation aboard Island Class patrol boats for the U.S. Coast Guard. The engines, which develop 2,880 bhp each at 1,500 rpm, will be used as main pro- pulsion on the patrol boats. The engines will drive through ZF re- verse/reduction gears. Electrical power for each craft is provided by two 99-kw generators driven by Cat- erpillar 3304T diesels.

Deutz MWM has begun deliver- ing 24 self-contained generating sets

Navy for their new patrol frigates.

Deutz MWM sold 32 sets of an almost identical configuration to the German Navy for use aboard their F-122 Bremen Class frigates.

Diesel engine manufacturer

Krupp MaK, which has more than 100 years' experience in naval equipment, offers a number of me- dium-speed, four-stroke heavy fuel engines in the output range from 740 to 9,900 kw (1,000-13,500 hp).

For example, Krupp MaK offers the heavy-fuel engines M453C and the M332, both of which boost low fuel consumption. The company re- ports that both engines feature ex- cellent ratio of maximum to mean piston pressures, but moderate, and therefore, safe, operational values.

The U.S. Coast Guard awarded a $9.2-million contract to the Electro-

Motive Division (EMD) of General

Motors for 32 propulsion engines, as part of an ongoing program to mod- ernize existing Coast Guard vessels which are being used throughout the coastal waters and the Great

Lakes.

EMD propulsion was also select- ed to power the U.S. Army's newest logistic support vessels (LSVs).

Each 273-foot LSV is powered by two EMD 16-1645-E2 diesel engines to speeds of about 12 knots.

The 270-foot Medium Endurance

Coast Guard Cutters under con- struction at Robert E. Derecktor

Shipyards in Middletown, R.I., are each powered by a pair of 3,500-hp

Alco diesel engines to speeds of about 19.5 knots. The ship's service electricity is provided by two 475- kw Caterpillar gensets.

Smaller Military Vessels

Within the past year, each of a series of seven Spanish Customs

Service patrol boats were fitted with a pair of Deutz MWM TBD 234 V- 12 diesel engines. Rated at 1,000 hp each, the engines directly drive Riva

Calzoni IRC 41 DL waterjets to pro- pel the 47-foot craft to speeds of about 54 knots. The engines ex- tremely low fuel consumption allows the vessels to operate for long peri- ods of time and in greater sea radius.

Cummins 4BT3.9-M turbo- charged four-cylinder diesel engines power Zodiac Hurricane rigid infla- tible boats (RIBs) employed by the

Canadian Coast Guard. Each of the 3.9-liter Cummins B Series diesels develop 100 horsepower at 2,500 rpm. The boats, which cruise at a speed of 14 knots, are propelled by a

Parker waterjet propulsion system.

The U.S. Coast Guard and Navy are both testing Cummins 6BT- and 4BT-powered Hurricane RIB dem- onstrators and a prototype.

MonArk Boat delivered a 28-foot search/rescue patrol boat to the

U.S. Coast Guard, which is powered by twin Volvo Diesel AQAD41/290 engines, each rated for 200 hp at 3,800 rpm. The all-aluminum craft, which features a semi-V planing hull, can obtain speeds in excess of 38 knots.
