Seawater coolers to LNG-fuelled wellboat

Tersan Shipyard 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.

 The vessel, which is newbuild number 1089 at Tersan Shipyard, is the sister vessel of the world’s first LNG-driven wellboat, “Bjørg Pauline,” which was launched in December last year.

The Nordlaks wellboat will be powered by a combination of LNG propulsion and battery pack. The new technology will reduce CO2 emissions by more than 20 percent and NOx levels by 90 percent compared to today’s wellboats.

Aalesund-based Hydroniq Coolers will supply three Pleat seawater coolers to the wellboat. The marine cooling system’s primary job is to safely reduces temperatures in the ship’s engines and other auxiliary systems through use of seawater.

Hydroniq Coolers’ patented Pleat is a module-based titanium cooler for seawater to freshwater, with design pressure 6 bars and design temperature of 0-95°C. It is the favoured seawater cooler for hundreds of shipowners worldwide as it is probably the market’s most reliable and maintenance friendly marine cooling system.

“The design of the Pleat significantly reduces the need to maintain the system. 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 to a traditional heat exchanger, one Pleat cooling element is equal to approximately 15 plates. Whereas cleaning a traditional plate heat exchanger can take a significant amount of time to complete, cleaning of the Pleat can easily be done buy one person within one hour,” says Jan Inge Johannesen, sales manager at Hydroniq Coolers.

Hydroniq Coolers will manufacture and assemble the equipment at its headquarter in Aalesund, Norway, and deliver it to Tersan Shipyard in Turkey. Hydroniq Coolers has not disclosed the value of the contract.

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

Hydroniq Coolers delivers marine cooling solutions to vessels that operate within offshore, shipping, cruise, passenger transport, fishery and fish farming. Shipowners, yards and ship designers are among the company’s customers and cooperation partners. The company is owned by Norwegian investment company SMV Invest AS (formerly Sperre Mek. Verksted AS).
