26/03/2012, ME-GI Dual Fuel MAN B&W Engines

This paper describes the latest developments in ME-GI dual fuel MAN B&W two-stroke engines and associated fuel supply systems.

 

15/02/2012, Ship Propulsion

For the purpose of this paper, the term “ship” is used to denote a vehicle employed to transport goods and persons from one point to another over water. Ship propulsion normally occurs with the help of a propeller, which is the term most widely used in English, although the word “screw” is sometimes seen, inter alia in combinations such as a “twin-screw” propulsion plant.

 

09/02/2012, Blended Edge Main Bearings

The blended edge (BE) design was introduced on thin shell white metal main bearings to better cope with crankshaft inclinations and thereby increase the resistance towards edge fatigue failures. The blended edge design is the corresponding item to the thick shell flex-edge design for MC engines.

 

18/01/2012, MAN B&W Double-Jib Crane

In the late 1970s, MAN Diesel & Turbo in Copenhagen conducted an investigation into the building-in heights of engine room cranes, and found that, at that time, all engine room cranes on the market required far too much headroom. We therefore decided to develop a particularly low-headroom crane, for which we were granted patents in many countries. The further development of this crane led to the ‘MAN B&W double-jib crane’.

 

18/01/2012, Low Container Ship Speed

Recently, fuel oil prices have risen to unprecedented levels, bringing fuel oil consumption of diesel engines more into focus than for a long time. At the same time, exhaust gas emissions in general and CO2 emission in particular are top priorities. One way of reducing fuel consumption as well as CO2 emission is to reduce the ship speed. Fig. 1 shows the relation between power and speed for a typical modern large post panamax container vessel.
