Norwegian researchers have discovered that by adjusting the technical layout in RSW tanks, it can improve the cooling of fishing more even.
Cflow and Sintef Ocean have run tests of RSW cooling on pelagic fish. The project is funded by FHF and the Research Council.
By simulating circulation in RSW tanks, it was shown that adjustments to the technical layout of the tanks could make the cooling of pelagic fish smoother – which corresponded well with testing in the field, writes FHF .
As there is great variation in how the cooling systems on board pelagic fishing boats are built up and operated, the aim of this project was to increase the competence in cooling pelagic fish on board fishing vessels. Selvåg Senior was used as a test boat in the project, but results have emerged that can benefit the entire industry. Project manager has been Cflow, which has worked closely with Sintef Ocean.
The results from different blue whiting loads with different flow have shown that it is possible to improve the cooling so that the load has an average temperature of the fish that is 2 ° C or lower when unloading.
The adjustments made to achieve this are summarized in the final report and on the project page FHF-901373 . Among other things, the results showed that switching between the outlet at the top and the aft grate had a large effect on the temperature distribution in the tanks. By leaving the outlet in the aft grate open for an hour and then letting the outlet go to the top, any dead zones were broken up and thereby a more even temperature in the entire load.
