New small-bore engines from MAN B&W

New small-bore engines from MAN B&W

MAN B&W Diesel has introduced two new engines S35ME-B and S40ME-B, a new addition to its small-bore diesel engines, upgrading the 35MC and 42MC engines to top-of-the-line electronically controlled engines that provide better economy, management and manoeuvrability.

Market investigation into this segment, including careful examination of the power against propeller speed for tankers, boxships and bulkers in the relevant size bracket, has shown that a 35 cm bore engine with slightly reduced speed at 167 rpm and higher engine power would suit the market well. In the segment for the S42MC type, a 40 cm bore engine with 146 rpm, together with the updated 35 cm bore engine, will cover the output range between the S26MC and the S50MC-C/ME-C types.

To fulfill the above requirements, electronically controlled fuel injection has been introduced on the new engines and, therefore, they have been designated S35ME-B and S40ME-B, respectively. As the production cost of the small two-stroke engines is of

paramount importance, the exhaust valve is still operated by a now smaller camshaft.

That these engines hit the right note in the market is confirmed by orders for both new types received from owners in Turkey and Cyprus. I?das ?elik Enerji Terasne ve Ula?im Sanayi A.S. in Turkey has just signed a contract for two 8S35ME-B for delivery in 2008. The engines will be built by MAN B&W Diesel in Frederikshavn.

The contract also covers MAN B&W Diesel CP-propellers of type VBS1280-ODS.

InterShip Navigation of Cyprus has ordered 6S40ME-B engines for 12 multipurpose vessels of 25,000 dwt, the first six of which are to be built in China. Six of the engines will be built by STX in Korea.

With the ME-B series, MAN B&W Diesel introduces the ME concept also for its small bore two-stroke engines, utilising the electronic concept for fuel injection control introduced on the large bore engines. Based on simple and well-proven diesel technology, the S35ME-B and the S40ME-B provide an engine that is geared to market requirements for electronic control, size reduction, fuel economy, high power, reliability, longer time between overhauls, lower propeller speed and better vessel manoeuvrability in the 5,000 to 25,000 dwt market.

Like on the larger ME-engines, the Alpha Lubricator is standard, with the benefit of a very low total lube oil consumption.
