PTG FRIONORDICA TO SUPPLY RSW SYSTEMS FOR NEW ROSTEIN VESSEL
PTG Frionordica to supply RSW systems for new Rostein vessel. PTG Frionordica AS has secured a contract with Larsnes Mek. Verksted to deliver two RSW (refrigerated seawater) systems for Rostein’s new Live Fish Carrier. This vessel, designed by Skipskompetanse in Måløy, and Larsnes Mek.’s build no. 74, will serve four fish farming companies along the Norwegian Helgeland coast, providing significant benefits for Norway’s supplier industry.
The RSW systems from PTG Frionordica are compact, comprehensive solutions for efficient cooling of seawater and fish. Previously, PTG Frionordica has provided similar systems for the retrofit of two other Rostein Live Fish Carriers.
“We are very proud to supply RSW systems once again to Rostein and Larsnes Mek. Verksted,” says Johnny Valle, Sales and Marketing Director at PTG Frionordica.
“It’s gratifying that the shipyard and shipping company value PTG Frionordica’s locally produced equipment.”
PTG Frionordica’s factory in Malmefjorden, Hustadvika municipality, employs around 60 people, including apprentices. Here, RSW systems are manufactured from initial welds to final paintwork, ready to be shipped globally.
“A newbuild generates positive ripple effects for Norwegian shipyards and suppliers, creating around 15–16 new jobs onboard this vessel in operation,” notes Rostein Vice President Glen Bradley.
The ship’s designer and builder are pleased that the project supports Norwegian and local businesses.
“With this vessel, Rostein has commissioned nearly NOK 5 billion in newbuilds at Larsnes Mek., highlighting the importance of the aquaculture industry to our shipyard and suppliers in Norway’s marine and maritime clusters,” says Jarle Gunnarstein, CEO of Larsnes Mek.
With a cargo capacity of 3,700 cubic metres, the battery-hybrid wellboat will feature cutting-edge fish welfare technology and two 2100 kW RSW systems from PTG Frionordica. Expected for delivery in Q2 2026, the vessel will serve fish farmers Lovundlaks Sjø, Kvarøy Fiskeoppdrett, Seløy Sjøfarm, and Kobbvåglaks on the Helgeland coast.
