Over time, this adjustment has been important in increasing value creation from fishing. A key challenge for the further development of the Norwegian pelagic fishing fleet will be to develop even better systems and solutions for handling and storing the catch. In this context, the shipping company Sydvestor AS has worked actively with the equipment suppliers to arrive at a new solution for loading and unloading pelagic fish. Furthermore, the company has contributed to developing a new concept for tank design.
Compared to traditional cargo tanks that have many angles and edges on the inside, the new tanks will have an oval shape and a smooth surface on the inside. This will contribute to far better circulation of the seawater in the tank which cools the fish, and which in turn will contribute to better quality. Furthermore, through such a solution, the energy requirement for pumps and the like can be reduced, and thus a more environmentally friendly and future-oriented total solution can be achieved. A smooth surface will also save the fish from impact damage during transport, especially at sea during bad weather.
Fish are traditionally pumped on board with a hydraulic paddle pump, which pumps fish and sea from the net / trawl and on board the vessel. On board the vessel, sea and fish are separated using a sieve box. The fish is further traditionally unloaded using a vacuum pump (system on board in addition to the paddle pump).
On board the projected vessel, the vane pump is replaced with a pressure load system. Through a large tank that can be pressure-adjusted, one can load the fish by forming negative pressure in the tank and unload the fish by forming overpressure in the tank.
It is assumed that the new system will be more gentle than the traditional one because:
• one removes the shovel which can contribute to impact damage to the fish and reduced quality
• newly developed “silk box” (mushroom) which distributes the fish to the tanks more gently and has improved filtration of the seawater, which means that the fish goes in tanks with clean cooled seawater
• improved tank system
The new system also allows you to cool the catch continuously from it the cargo on board until it is unloaded on land. In a traditional facility, it is difficult to cool the catch during the loading and unloading operation. The new facility therefore contributes to continuous cooling with the catch on board and which in turn provides better quality.
In this project, some financial support is provided for the construction of the pilot facility, as well as documentation of the facility's structure, operation and quality of catch delivered from the vessel.
The mentioned issues fit well with the outlined R&D tasks for this fleet group in the Fisheries Technology Action Plan 2010–2012.
Goals:
• To build and test a new fish tank concept that provides increased flexibility and significantly improved quality of pelagic fish.
• To evaluate the effect on the quality of a new concept for handling and storage / cooling of catch on board pelagic vessels.
