MAN B&W Announces APL

Ships Order; Introduces

S35MC Model

MAN B&W, a leader in maritime propulsion, has announced that three 4,800-teu post-Panamax ships booked by American President Lines (APL) from the HDW yard in Ger- many will each be powered by one of

MAN B&W's 11-cylinder K90MC-C engines. The 900mm bore/2,300 mm stroke engines, which have a maxi- mum output of 48,840 kW (66,385 bhp) at 104 rpm, will be built in

South Korea by Hyundai's Engine &

Machinery Division and delivered to the yard during 1994 and 1995.

The customers for K90MC and

K90MC-C engines include A.P.

Moller, the East Asiatic Company,

Hyundai Merchant Marine, NYK,

Mitsui OSK, Hapag-Lloyd, Neptune

Orient Lines and the Malaysian In- ternational Shipping Corporation.

The design is tailored to large containerships requiring service speeds of 25 knots or more. The comparatively short stroke and light weight of the engine promotes a more compact machinery room and hence optimized box capacity in ships of

Panamax or post-Panamax dimen- sions. Outputs up to 51,830 kW

Cross section of the MAN B & W S35MC Engine. (70,440 bhp) are offered by the

K90MC and K90MC-C series, en- suring ample reserves of power for contemporary containership projects. MAN B&W also announced the addition of the S35MC long- stroke low speed 350mm bore model to its MC program, designed to de- liver even higher propulsion plant efficiency for small- to medium-sized ships. The 1,400mm stroke of the

S35MC yields a stroke/bore ratio of 4:1 and a nominal speed of 170 rpm.

The layout flexibility enables opera- tors to select maximum continuous speeds between 170 rpm and 145 rpm for optimum propeller effi- ciency. An output of 700 kW (950 bhp) per cylinder is delivered at 170 rpm. The S35MC series embraces four- to 12-cylinder models covering an output band from 1,900- to 8,400- kW (2,580 to 11,420 bhp), to propel a wide range of ship types economi- cally. A specific fuel consumption of 129g/bhph 175 g/kWh) contributes to lower running costs.

The S35MC design is based on the successful 350mm bore/1,055 mm stroke L35MC, with the same very short length as the L-type, about 900mm higher and only slightly heavier. The S35MC engine joins the MC two-stroke program, which embraces low speed designs with bore sizes from 260mm to 900mm, and outputs ranging beyond 51,470 kW (70,000 bhp).

USCG Shipyard In Maryland

Receives Top Quality Award

The Commandant of the U.S.

Coast Guard (USCG) recently an- nounced his selection of the USCG

Yard in Curtis Bay, Maryland, as the recipient of the First Annual

Commandant's Quality Award. The

Yard placed first among 15 other

USCG nominees throughout the U.S.

The Service's nearly century-old shipyard's winning evaluation was based on quality success stories and unique achievement attained through quality management.

How to get the best possible atmospheric protection during tanl{gauging.

Restricted i

Each of these MMC Trimode"

Flexi-Dip™ gauging tapes will give you the same accurate measurement of ullage, interface and temperature — and do it quickly in a single tank penetration.

But the Closed model goes even further. It is gas-tight, especially when the vapor valve is open. This meets the stringent requirements of the U.S. Coast

Guard for vapor-recovery situations, especially during the loading process.

Both are very simple to use. Ullage and interface indications are audible: a steady tone when the probe reaches oil and a beep-beep when it senses water. The tempera- ture is shown as a digital LCD readout on the hub. The tapes are marked in feet and inches on one side, metric on the other. (However, with the

Closed model, this dual reading feature is not applicable; you must choose one or the other.)

MMC tapes are approved as intrin- sically safe by FM, BASEEFA, CSA and

SAA, and are also IMO-approved for tankship use.
