PROPULSION UPDATE

Westinghouse Proclaims ICR Engine

A Success At NYC Meeting

Westinghouse said a project for developing a fuel-saving engine for the Navy was moving along well at a Feb. 15 joint meeting of the New

York Metropolitan section of the

Society of Marine Engineers and

Naval Architects (SNAME), the

American Society of Naval Engi- neers (ASNE), and the Institute of

Marine Engineers (IME).

Westinghouse is the overall con- tractor of the WR-21 Intercooled

Recuperated (ICR) engine for the

U.S. Navy, the project having been developed with industry leaders like

Rolls-Royce and Allied-Signal Aero- space Systems and Equipment.

According to John Chiprich,

ICR Project/Applications engineer- ing manager, the project is a suc- cess, with projections met or sur- passed—and the Navy has even ac- celerated the timetable. The ICR promises the following: • Efficiency. "The biggest attrac- tions are fuel efficiency and opera- tional range," said Mr. Chiprich. "It's a relatively flat consumption curve." The WR-21 incorporates an intercooler and recuperator into the normal engine cycle. The inter- cooler cools air entering the high pressure compressor, reducing the work necessary to compress the air and keep the high pressure com- pressor discharge temperature down to increase the effectiveness of the recuperator.

The result, according to Mr.

Chiprich, is elevated power output for given air flow. Using gas turbine exhaust air, the recuperator pre- heats the combustion air, report- edly improving cycle efficiency. Mr.

Chiprich said firing temperature is maintained at a nearly constant level over the full power range to maximize cycle efficiency, resulting in 30 percent less fuel usage against a typical Navy operating profile. At 26,400 hp, the engine is required to have a specific fuel consumption of

Cross-section .36 lb/hp-hr. The engine is rated 29,000 hp at 100 degrees Fahren- heit, 40 percent relative humidity at sea level. • Environmental Friendliness. By using variable area turbine nozzles, firing temperatures are maintained nearly constant even at low power levels, reducing CO and unburned hydrocarbon emissions. • Ease of Installation. The engine has removable panels for mainte- nance flexibility, and the package is relatively small: 315 inches (8,001 mm) long, 104 inches (2,642 mm) wide and 180 inches (4,572 mm) high at the recuperator housing. It weighs 110,000 lbs. (41,602 kg) on the mounts, with a total package weight of 120,000 lbs., as per Navy the ICR engine, requirements. • Cost Effectiveness. Mr. Chiprich estimated the ICR would save the

Navy $1.5 million per year per ship, and the initial projection of 1,000 hours Mean Time Between Failures (MTBF)was increased to 1,600 hours in the finished product, decreasing maintenance and repair costs.

The engine is slated for installa- tion into an FY '96 DDG-51 Class destroyer, but commercial inquiries have reportedly already begun. "Pro- duction orders for commercial ves- sels can follow almost immediately,"

Mr. Chiprich said.

O'Boyle Named Sales Agent

For Sobrena And Sociber

Richard F. O'Boyle, Inc. has been named sales agent in the U.S. and

Canada for Sobrena of Brest,

France. Paul Philippe, sales man- ager for Sobrena, said that over 70 percent of the shipyard revenue comes from non-French owners.

Sobrena, with three drydocks and five repair berths, has the capabil- ity to handle any type and size ves- sel up to 550,000 dwt. Sobrena says it is particularly well orga- nized to service tank ships with modern slop handling facilities in place. Richard F. O'Boyle Inc. also recently became U.S. and Canada shiprepair sales agent for Sociber

Two Oil-Recovery Barges

Completed For MSRC

Diversified Marine, Inc. recently completed converting two barges for the Marine Spill Response Cor- poration (MSRC). This contract amounted to over $1 million per vessel. The two tank barges, both classed ABS A1 for oceans, were purchased from West Coast opera- tors and delivered to the Diversi- fied dock on the Columbia River.

The extensive alterations began with the existing pumping systems and machinery, which were over- hauled wherever possible.

The 278-foot (84.7m)Sausebarge with a 47,000 barrel capacity be- came the MSRC 404. Its pair of below-deck Detroit 8-71 pumping engines were rebuilt and placed in the new deck house to comply with regulations for Grade A oil. The 248-foot (75.6 m) Hawaiian barge, 32,000 barrels capacity, became the

MSRC 320. Since it was formerly carrying Grade A oil, the engines were already on deck. The line-up in the engine house now comprises four rebuilt Detroits. For more informa- tion on Diversified Marine,

Paxman Diesels For New

U.K. Patrol Vessel

Paxman, a GEC Alsthom Diesels company, has supplied two Paxman

Vega 12CM diesel engines for an 82- foot (25 m) U.K. Customs and Excise protector class patrol craft, HMCC

Vincent.

The existing protector class de- sign was modified during construc- tion by Babcock Thorn Ltd., the com- mercial managers of Rosyth Royal

Dockyard, to provide a vessel suit- able for a wide range of law enforce- ment duties which include counter- ing smuggling and offshore terror- ism as well as fishery protection, covert surveillance and sea rescue missions.
