    Abstract

    The ship energy flow simulator, developed originally by Deltamarin, ABB and VTT, was utilized for evaluating the potential in the cargo ship fresh cooling water system, considering the individual requirements from the various components in the cooling system. With the tool, the main topology for an efficient cooling water system could be demonstrated. The system consists of a balanced ring network with an optimal set-up of pumps and heat exchangers that were dimensioned for both minimizing the building cost and performing best at the average operation conditions, instead of the extreme design conditions. The cooling system is controlled by varying both flow rate to components and return temperature to the central cooler according to the operation profile. This new design method can efficiently support the ship design work already at the crucial concept development phase, where the main decisions regarding ship energy efficiency are made.
