The new Aqua Skilsøy well boat was delivered earlier this year from Turkey’s Sefine Shipyard to the DESS Aquaculture Shipping company in Grimstad on Norway’s south coast.
This is the third in a series of six such vessels equipped with sustainable refrigerated seawater (RSW) systems from PTG Frionordica.
Twelve in all
A total of 12 RSW units with outputs of 1 750 kW are being supplied by the PTG company to the series. Aqua Spa and Aqua Maløy have already received two each.
DESS Aquaculture Shipping’s diesel-electric well boats are 84 metres long and have a tank capacity of 3 900 cubic metres. Their water-treatment capability is high, and they are prepared for new methods of combating lice and illness.
The company has developed the vessel concept in collaboration with Salt Ship Design, the Turkish newbuilding yard and Cflow.
Natural refrigerants
The RSW units are equipped with control and alarm system from PTG Friologica. PTG Frionordica’s RSW systems utilise ammonia (NH3) as a natural refrigerant and come in standard sizes from 350 to 2 500 kW.
They have a very high performance in relation to electricity consumption, are space-saving and require a low refrigerant load.
