Influence of keel coolers use on ship energy efficiency: A case study and evaluation

There is a significant increase in the attention given to green maritime ship technologies due to the growing importance of sustainable operations. mainly due to the implementation of several new legislative actions taken by the International Maritime Organization (IMO). There is considerable potential for reducing emissions in the shipping sector. Various solutions are already existing and a plethora of technologies available for retrofitting on existing vessels. The article presents an example of practical application of energy saving by fitting the central cooling system with keel cooler on the Car Ferry “ASD” trading in west Africa. The use of that solution is limited to small ships, with new development, central cooling system with keel coolers has a chance to spread out on bigger ships in the future. It will mainly depend on efficiency and reliability of keel coolers secure systems.
