Texas, and Spirit of Texas, built by Levingston Shipbuilding, of Or- ange, Texas, for Asco Falcon I are powered by twin Enterprise R4-

V12 direct-reversing engines, giv- ing each ship a total of 15,600 hp.

By burning residual fuels these vessels remain competitive with international dry bulk carriers.

Twin Enterprise R4-V16 en- gines propel U.S. Steel's M/V Ed- win H. Gott, a mammoth ore boat longer than three football fields.

Inspections of the main propulsion engines continue to show clean in- ternals and very low wear rates under heavy fuel service.

Ship service diesel generators for three American President Lines containerships were supplied by

Transamerica Delaval. Con- structed by Avondale Shipyards of

New Orleans, these are the largest containerships ever built in the

U.S. Their refrigerated cargo is safeguarded by three heavy fuel burning Enterprise R4-L6 diesels, rated at 2500 kw each.

Four Enterprise R4-V16 engines power two 35,000-dwt tankers built by Bath Iron Works for Falcon I

Volvo Penta has introduced a new, improved version of its tur- bocharged 12-liter diesel engine, the TMD 120. Specially designed for use as the main engine in workboats and leisure craft, it is claimed to exhibit high output in relation to weight and installed di- mensions, low fuel consumption, and a high level of operational reliability.

The B-version of the TMD-120 features advanced control of the injection and combustion processes with new injectors which provide the possibility of more rapid injec- tion at higher pressure and with decreased combustion delay. To- gether with efficient turbocharg- ing and a combustion chamber of new design, this will yield a con- siderable improvement in efficiency.

Other technical refinements in

Volvo Penta's 12-liter diesel in- clude piston-cooling, a hose-free seawater system with a heat exchanger, and thermostat-con- trolled cooling of the engine block, cylinder heads, turbo, and exhaust manifold.

The Swedish firm's line of die- sels includes 2, 3, 4, and 6-cylinder engines covering 12 different models. Some models are equipped with turbochargers and others with both turbo and after-coolers.

Additionally, Volvo Penta offers twin engines driving through a compound gear providing a single shaft output from 336 shp to 580 shp. The twin-engine/single-out- put package provides many advan- tages including "take-home" capa- bility on one engine.

A wide range of accessories de- signed for commercial use are available such as front or side mounted power take-offs, flexible (continued on page 38) 36 Write 821 on Reader Service Card Maritime Reporter/Engineering News
