The tuna purse seiner

The tuna purse seiner is designed for the multi-purpose functions of spotting, catching, refrigerating, storing, transporting and unloading the catch. The vessel is of the raised deck type with pilot house, living and berthing quarters forward, fish hold space amidships, and engine room aft. Fishing and net handling machinery, as well as working space, are located on the upper deck, aft of the superstructure.

Fish will be transported from the upper deck to the fish wells via a turret through the upper deck and a conveyor with side transfer chutes to direct the fish into the wells. During unloading, these side transfer chutes will be used when floating the fish to the fish well coaming and onto the conveyor. Fish can also be unloaded dry through the fish well unloading doors. The refrigeration system is be capable of brine chiller freezing, flooded brine freezing and either wet or dry storage of tuna in coiled fish wells.
