This paper deals with the latest developments of the MAN B&W ME-GI-S and ME-LGI-S dual fuel two-stroke low speed diesel engines and associated fuel gas supply systems. The discussion about and the requirement for lowering CO2, NOx, SOx and particulate emissions have increased operators’ and owners’ interest in investigating future fuel alternatives. The MAN B&W ME-GI-S and ME-LGI-S engines offer the opportunity of utilizing such alternatives, also for stationary application. The gaseous/liquid fuel flexibility makes the MAN B&W ME-GI-S and ME-LGI-S engines an obvious choice for projects where the engine is connected to interruptible gas supply systems or where a switch/mixing ratio among various fuels is required for various reasons.

In 2012 MAN Diesel & Turbo decided to expand the engine portfolio with engine designs that allow operation on fuels with low flashpoints. Since then, nine engines of the 50-bore MAN B&W engine design intended for operation on methanol have been ordered. The orders placed are based on MAN Diesel & Turbo’s proven MELGI design concept and the engines will be delivered in 2015 from various licensees. On 17 March 2015, the first test on methanol was completed at MAN Diesel & Turbo’s Diesel Research Centre in Copenhagen, Denmark, in the presence of classification societies, shipowners, licensees and fuel gas system makers. This technical paper focuses on the technical data obtained from this test and the subsequent test made on a 4-cylinder engine in Japan. PDF, 2.67 MB
The demand for energy and technological development is increasing worldwide. Ideas, proven by operational experience on reciprocating engines with the highest possible efficiency level, are subject to renewed interest. This paper deals with the use of alternative fuels in MAN B&W two-stroke low speed engines for stationary application. PDF, 1.71 MB

In recent years, the stationary diesel engine market has seen a demand for units running on biofuel. The nature of this demand is driven by the desire to be CO2 neutral, based on reliable, fuel efficient and environmentally friendly power generation for both public utilities and Independent Power Producers (IPPs). This demand is being met by modern marine application derivative medium speed diesel gensets and two-stroke low speed crosshead uniflow diesel engines, capable of burning almost any mineral fuel available on the market, whether liquid or gaseous. This paper deals with the application scenarios of such engines and their biofuel capability and describes the installation examples of such engines. PDF, 633.16 KB
In recent years, the stationary diesel engine market for large diesel units has seen an increasing demand for reliable and fuel efficient power plants in the range of 30-250 MW, based on cost effective refinery residuals. The demand is met by the modern medium speed diesel GenSets and, for the larger units, by the two-stroke low speed crosshead uniflow scavenged diesel engines, the latter capable of burning almost any fuel available on the market, whether liquid or gaseous. This paper will deal with the service experience gained from two-stroke low speed diesel engines and their fuel capability as well as describe various installation examples. PDF, 2.27 MB
