- 24/10/2007, Propulsion Trends in LNG Carriers, Two-stroke Engines
- Natural gas is a “clean” fuel compared to diesel and heavy fuel oil and, together with an increasing environmental responsibility, there is a rising demand for natural gas worldwide. Where it is not possible to transport natural gas by means of pipelines, the LNG (Liquid Natural Gas) carriers have to take over the transportation because natural gas in liquid form at atmospheric pressure only takes up 1/600 of the natural gas volume.
- 04/10/2007, MAN B&W Low Speed Large Bore Engines Now with Higher Power Concentration
- This paper will describe the updating of our S/K80ME-C and K90ME/ME-C engines from a technical and marketing perspective. Owing to the fact that the K types of these engine types were originally designed as offsprings of the L80MC and L90MC engines back in the 1980s, there is substantial cost down potential in updating as well as uprating the engines, also utilising the design features of today.

The demand for system engineering and package responsibility has grown in recent years. One reason is the reduced technical staff at most shipyards in combination with outsourcing of technical work to consultants and partners.
- 19/07/2005, Thermo Efficiency System
- Following the trend of required higher overall ship efficiency since the first oil crisis in 1973, the efficiency of the main engines has increased and, today, the fuel energy efficiency is about 50% This high efficiency has, among others,led to a correspondingly lower exhaust gas temperature after the turbochargers.
