This paper investigates thermal storage integration with the refrigerated seawater (RSW) system of a fishing vessel. Four different scenarios were investigated, including ice in tanks, two design modifications in chilling tanks, and plug-in thermal storage. The use of ice in chilling tanks as cold thermal storage was assessed since it can assist RSW system and reduce total chilling time. This was done by the addition of 5 m3 ice, which resulted in a reduced cooling time of 30 minutes. Suggestions for design modifications in chilling tanks were also introduced to assess the potential of built-in thermal storage. A concept for plug-in thermal storage was also designed, employing a phase change material of 4 °C. Results showed that 1 m3 thermal energy storage could provide an average of 30 kWh for chilling fish during peak load.
