Hydroniq clinches order for biggest-ever wellboat

Turkey’s Cemre Shipyard has awarded Norwegian company Hydroniq Coolers a contract to deliver the marine cooling system to two wellboats the yard is building, including what will be the world’s largest live fish carrier.

Hydroniq Coolers will supply its hull-integrated “Rack” seawater cooling system to the 110-metre-long Seigrunn and the smaller Seifjell, which are being built for Norwegian wellboat company Seistar Holding.

The Seigrunn will have a capacity of 8,000m³, making it the world’s most capacious live fish carrier.

The Rack cooler is integrated in the hull below the main engine room of the vessel, where it reduces temperatures in the ship’s engines and other auxiliary systems through use of seawater, but without taking up valuable engine room space, said Hydroniq in a press release. This is a favoured solution for both vessel crew and owners.

‘Popular choice’

“Our Rack seawater cooler is the most popular choice amongst the Norwegian shipyards that are building wellboats. It is becoming increasingly popular internationally too, with Cemre Shipyard being one of the international frontrunners who are very familiar with our technology,” said Jan Inge Johannesen, sales manager at Hydroniq Coolers.

Developed by the SALT Ship Design, the Seigrunn will have a larger capacity than both the Sølvtrans vessel Ronja Storm, which is currently the world’s largest operational wellboat, and the Frøy Rederi wellboat Gåsø Høvding, which is due to knock Ronja Storm off the top spot.

“Some would argue that size doesn’t matter, but everyone in the maritime and aquaculture industries will admit that it is always fun to be involved with the biggest projects. We at Hydroniq Coolers are no different, and we look forward to delivering a seawater cooling system that is a perfect fit for these very different vessels,” said Johannesen.
