PROPULSION UPDATE Propulsion Plant Debut For MAN B&W's Mini-Bore, Two-Stroke Diesel Engine Free Brochure Available The Japanese feeder confainership Rokku Maru features the first MAN B&W S26MC diesel engine installation. The recent seagoing debut of MAN B&W Diesel's S26MC two- stroke design—plus a growing order backlog—suggest that there is a strong market for what is reportedly the world's smallest low-speed crosshead engine in the small-to- medium oceangoing, coastal and in- land ship propulsion market. The 260-mm bore/980-mm stroke engine was released last year to extend the economic and technical merits of MAN B&W's MC two- stroke program for ships which were previously restricted to four-stroke, medium-speed geared machinery. The S26MC range encompasses four to eight-cylinder models, which of- fer outputs ranging from 700 kw (950 bhp) to 2,920 kw (3,970 bhp) at speeds of 250 rpm or less, allowing direct-coupling to the propeller. The overall operational advan- tages of the new model—including high reliability, low maintenance demands and impressive fuel econo- my on low grade bunkers—have at- tracted Asian and European owners. Interest has intensified with the en- try into service of the first S26MC marine installation—a six-cylinder model powering the Japanese 126- TEU feeder containership, the Rok- ku Maru. The 6S26MC engine installed aboard the 239-foot containership, which was subcontracted to Han- shin Diesel by MAN B&W licensee Kawasaki, develops 2,185 kw (2,970 S26MC CROSS SECTION \\ r fCP^ bhp) at 250 rpm and is directly cou- pled to a CP propeller for a design speed of 14.3 knots. Both the shipowner, Marui Kauin, and shipbuilder, Yamanaka Shipyard, reported that the engine performed well during sea trials with the use of heavy fuel with a 0.9963 specific gravity and 165 cSt viscosity. Very little smoke was ob- served under all maneuvering condi- tions, and none at all at full load. Low noise and vibration levels— notable features of the design—also confirmed expectations.

The debut marine installation will provide a convenient practical testbed for longer term monitoring of the S26MC engine on heavy fuel. The operational integrity and per- formance of the design have already been well proven by the six-cylinder prototype after over a year of ex- haustive testing at MAN B&W Al- pha Diesel's factory in Frederik- shavn, Denmark. The initial devel- opment goals have been comforta- bly met within the engine's poten- tial margins. The prototype 6S26MC engine is now available for sale.

The order for a fourth ship will be held over until next year when another batch of new vessels will be announced. Each ship is about 10 million pounds ($17 million) cheaper than the average of three earlier Type- 23s ordered in 1986, bringing the price to about 105 million pounds per vessel ($179.5 million). The three new Duke-class ships— the Iron Duke, Monmouth and Montrose—follow four other Type- 23s already under construction, three at Yarrow. The number of new frigates of all types now on order for the Navy is now 10. Type-23 is the main anti- submarine ship envisaged for ser- vice over the next decades. Plans call for the government to order two new frigates next year, two in 1990, three more in 1991, and again the following year. This will ensure that aging ships are replaced and the escort force of about 50 is maintained. for free literature giving details on the facilities and capabilities of Yarrow Shipbuilders, Circle 52 on Reader Service Card HYDRAULIC CRANES Aerial Baskets Knucklebooms Digger Derricks Pressure Diggers HiRail Equipment 80 Used Units in Stock sold as is or reconditioned Wanted - listed used equipt, nunvi/l.^c Trucks & Equipment \trlt I iVIli o Hatfield, PA 19440 (PHILA. AREA) (215) 721-4444 Kiene Diesel Offers Free Literature On Cylinder Pressure Indicator K-100 Kiene Diesel Accessories, Inc. of Addison, 111., is offering free litera- ture on their cylinder pressure indi- cator K-100 for reading firing and compression pressures on gas or die- sel engines. The patented K-100 utilizes the "trapped pressure" principle, whereby cylinder pressure is "trap- ped" within a chamber and the pressure read directly and conven- iently on a high-quality bourdon gauge. This field-proven concept re- duces the moving part of the indica- tor to a single lightweight, high- temperature resistance valve, thus eliminating springs, counters, pis- tons and other operating problems. The literature contains ordering information on the Model K-100 cylinder pressure indicator, as well as Model K-101 and Model K-107. Also discussed are V-line indicator valves for two or four-stroke/cycle gas or diesel engines.

The last of the 5,700-car-capacity vessels ordered by Pan Ocean at the South Korean shipyard two years ago, the newly built car carrier will be put into service on the north American and European route to carry South Korea's export cars. Other vessels delivered to Pan Ocean this year include the Auto Atlas and Auto Benner in March, and the Auto Champ in June. 72 Maritime Reporter/Engineering News
