TERSAN Shipyard in Turkey has awarded Hydroniq Coolers a contract to deliver its Pleat seawater coolers to a wellboat the yard is building for Norwegian salmon producer Nordlaks AS.

A well-boat is a fishing vessel with a well or tank for the storage and transport of live fish.

The vessel is the sister vessel of the world’s first LNG-driven wellboat, Bjørg Pauline, which was launched in December last year.

The Nordlaks wellboat is to be powered by a combination of LNG propulsion and battery pack.

The new technology is aimed at reducing CO2 emissions by more than 20% and NOx levels by 90% compared with today’s wellboats.

“The design of the Pleat significantly reduces the need to maintain the system,” said Hydroniq Coolers sales manager Jan Inge.

“However, when maintenance is required, it involves dismantling, high-pressure cleaning, and assembly of a few robust elements that are easy to get watertight again.”

Compared with a traditional heat exchanger, one Pleat cooling element is said to equal about 15 plates.

Hydroniq Coolers are to manufacture and assemble the equipment at its headquarters in Aalesund, Norway, and deliver it to Tersan Shipyard in Turkey.

The 84.26-metre long and 19 metres wide wellboat is to carry up to 600 tonnes of live salmon and trout for Nordlaks. The vessel has been designed by NSK Ship Design in Harstad, Norway and is to delivered from Tersan Shipyard in 2021.
