The RDPS Alpha piston sealing system has been developed to counter problems resulting from the effects of emission regulation and slow steaming on cylinder lubrication, as described by Ernie Terry of Marine…

At the recent SMM exhibition in Hamburg, Caterpillar Marine Power Systems announced that it is currently developing a high speed gas engine based on the 3500 engine platform.

The pressure to find alternative fuels, driven by both emissions legislation and the resulting commercial pressures that threaten to drive up the cost of low-sulphur fuel oils, is impacting on the low…

Wärtsilä’s so-called ‘new generation’ – the Generation X series – of two-stroke engines was introduced in May 2011, with the aim of significantly contributing to lowering marine engine fuel costs and improving…

Caterpillar Marine Power Systems has announced a new high-speed propulsion engine based on its 3516 platform, but optimised to deliver clean-burn combustion along with an up to 15% power increase in its…

MAN is adding a new string to its bow in the dual-fuel stakes through the development of the 35/44DF marine engine, to serve a broad power band in 10 configurations, writes David…

Some are still on the drawing board, but a range of new propulsor designs are expanding speed and manoeuvrability limits for high speed vessels, says Wendy Laursen.

Henrik Segercrantz speaks to MAN Diesel & Turbo about the future of four-stroke propulsion, particularly concerning passenger vessels.

David Tinsley describes an innovative, Norwegian-developed electric propulsion system ordered by Samsung Heavy Industries as part of a South Korean ‘green ship’ initiative.

A study by MAN Diesel & Turbo compares a diesel mechanical plant with CP propellers operating with constant engine speed with operations at variable engine speed on an offshore vessel. Henrik Segerkrantz…
