The aim of this study is to compare commercial fuel cell types that can be used in merchant ships and a maximum of 5 MW main engine power is considered due to the limited power output of fuel cells. The environmental and economical performances of fuel cell types were compared and criterion...
Perhaps one of the most innovative rudder mechanisms you will ever come across. Suppose you have aship, too large to be manoeuvrein a basin with size constraints, such that the ship cannot use its propeller during the manoeuvre. This situation often arises in case of large ships operating in...
Since the time man started using ships, various types of propulsion systems have been used depending on the ship’s requirement. In this article, we will try to have a brief overview of the kind of propulsion systems that are available in the market and their selection procedure according to ...

The traditional method of dealing with this boil off is to specify steam propulsion for the vessel and utilise the boil off as fuel in the boiler. The disadvantage of this is that initial cost is high and efficiency is low in comparison to reciprocating engines. The advantage is the proven ...
They come in two kinds: the crude carrier, which carries crude oil, and the clean products tanker, which carries refined products such as petrol, gasoline, aviation fuel, kerosene and paraffin. Tankers range in all sizes from small bunkering tankers of 1000 DWT, used for refuelling larger ...
