MARINE PROPULSION

Latest Developments From The World's Leading Manufacturers

Long a dominant force in the marine power market, MAN B&W

Diesel, one of the world's largest manufacturers of slow- and medium- speed diesels, has been particularly successful in recent years in the containership propulsion market.

In the U.S., for instance, the re- cently constructed Matson Naviga- tion boxship Pfeiffer features a MAN

B&W 8180MC slow-speed diesel, with a rating of 33,680 bhp at 88 rpm. Prior to the Pfeiffer installa- tion, MAN B&W Diesel engines were fitted on the last three containerships built in the U.S. at

Bay Shipbuilding.

Five post-Panamax boxships be- ing built by Hyundai Heavy Indus- tries in South Korea for Hyundai

Merchant Marine will be powered by some of the most powerful ma- rine diesels ever ordered. Each 4,000-TEU-plus vessel will be fea- ture an MAN B&W 12-cylinder

K90MC-C engine offering a maxi- mum output of 70,320 bhp at 104 rpm. The 900-mm bore/2,300-mm stroke K90MC-C design is tailored to the demands of large new genera- tion boxships which require speeds in excess of 25 knots.

Other recent installations: a se- ries of eight Hapag-Lloyd 4,400-TEU containerships built at Samsung

Shipbuilding, and another 4,400-

TEU boxship built by HHI for MISC.

Also part of the MAN Group,

MAN B&W Holeby offers the 23 and 28 Series gensets. Covering a power range of 500 to 4,000 kW, the five-to 18-cylinder models operate on eco- nomical heavy fuel oil, have excel- lent overhaul intervals and unlim- ited low-load/no-load operation, while still conforming with environ- mental emission requirements.

Japanese manufacturer

Mitsubishi Heavy Industries (MHI) recently introduced a long-stroke version 240-mm bore six-cylinder engine to its medium-speed diesel engine SU series. The in-line six- cylinder S6U2 engine has a stroke of 300 mm, increased from the 240 mm stroke of previous SU engines.

MHI reports that fuel consump- tion has been improved by optimiz- ing turbocharger performance and inlet and exhaust valve timings; and

NO emissions—whose reduction is critical in light of new environmen- tal pollution regulations—have been lowered with modifications in the fuel injection system.

The SU series, introduced in the late 70s, includes two in-line mod- els, six- and eight-cylinder versions, and two Vee configurations, 12- and 16-cylinder models. The power range covers from 750-3,680 kW (1,006-4,935 hp) at speeds ranging from 720 to 1,200 rpm.

German engine manufacturer

Krupp MaK is now able to offer heavy fuel-burning in-line diesels

September, 1992 ranging in power from 800 to 11,000 kW (1,072-14,751 hp) to the ship- building industry, thanks to its re- cent introduction of the M 20 en- gine. A long-stroke design, with a bore of 200 mm and stroke of 300 mm, the M 20 has a speed range from 900 to 1,100 rpm. The diesel is available in in-line models of six, eight and nine cylinders and 12- and 16-V configurations. Series production of the in-line models is expected to begin shortly, while V configuration models will be avail- able within the next two years.

With the M 20 engine introduc- tion, Krupp MaK hopes to increase its reported 15 percent share of the medium-speed diesel small vessel propulsion and ship auxiliary mar- ket.

The newly launched 1,300-pas- senger CostaClassica and her sis- ter, the CostaRomantica under con- struction at Fincantieri in Italy, each have main propulsion systems com- prised of eight-cylinder Sulzer

ZAL40S medium-speed engines, providing a combined output of 28,800 bhp, and four 3,660-kW gensets driven by 12-cylinder GMT

A320 engines.

The first commercial icebreaking research ship under the U.S.-flag, the recently delivered Nathaniel B.

Palmer, features Caterpillar pro- pulsion. The 308-foot ship, built by

North American Shipbuilding of

Larose, La., is fitted with four Cat- erpillar 3608 diesels, rated at 3,180 bhp at 1,000 rpm, with two nozzled

Ulstein stainless steel controllable- pitch four-blade propellers. Four

Caterpillar 3512s, in combination with KATO generators, supply ship's power.

The newly launched class of Ma- rine Spill Response Corporation (MSRC) vessels also feature Cat power, with twin 3512 C main en- gines, totaling 3,000 hp, in combi- nation with Reintjes reduction gear- ing with turbo Voith couplings.

Caterpillar along with Cummins have also become the dominate choice in the hot casino boat mar- ket. For example, Cummins en- gines power the Alton Belle Casino and Dubuque Casino Belle, while

Cat diesels provide propulsion aboard the Emerald Lady, Diamond

Lady, Par-A-Dice and Empress

Riverboat Casino.

However, MTU of North America made a major breakthrough into the riverboat casino market with a recent order for a total of six main propulsion, auxiliary and bow thruster engines. The MTU diesel package will be installed on the 210- foot, 1,200-passenger riverboat ca- sino under construction at Leevac

Shipyards in Jennings, La., for

Southern Illinois Riverboat Casino/

Player's International. Two resil- iency mounted MTU 12V 183-

TE62s, rated at 750 hp each at 2,000 rpm, will supply propulsion power, via ZF BW255 reverse reduction gearing, while two 720-kW 8V 396TE-54s will provide auxiliary power. A 405-hp 12V model 183AA91 diesel will supply power to the Schottel SST-170-T 400-hp bow thruster. A sixth engine, a 6R 183AA51 diesel, drives a 120-kv gen- erator.

The gaming/passenger vessel is a natural market for its engines, MTU feels, because of the company's ex- tensive sound- and vibration-damp- ening experience, particularly in the patrol boat market. Discussions for additional riverboat casino engine 33
