Low Speed

18/01/2012, Ship Propulsion Basic Principles of 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.

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’.

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.
 
02/08/2011, Propulsion of 46,000-50,000 dwt Handymax Tanker
The main ship particulars of 46,000-50,000 dwt Handymax tankers are normally as follows: the overall ship length is 183 m, breadth 32.2 m and design/scantling draught 11.0 m/12.2. Recent development steps have made it possible to offer solutions which will enable significantly lower transportation costs for Handymax tankers (and bulk carriers) as outlined in this paper.

The need for seaborne transportation will increase significantly in the years to come. At the same time, the fuel oil price is increasing, stricter emission requirements are coming into force, and the public is becoming more concerned about the environmental footprint of shipping.
