The KV Jan Mayen, delivered in May 2023, is the first of three offshore patrol vessels in the Jan Mayen class, designed for the Royal Norwegian Navy. Built by Vard Langsten, the vessel’s primary mission is to support Norway’s extensive coast guard operations, which include fisheries inspections, search and rescue, oil spill response, and territorial defense.
At 136 meters long and with a displacement of 10,400 tonnes, the Jan Mayen is powered by four Bergen B33:45L8A generator sets, each delivering 4.8 MW, providing reliable power for both its propulsion and operational systems. These engines are designed for high performance and fuel efficiency, enabling the vessel to operate in the challenging environments often encountered by the Norwegian Coast Guard.

The delivery of the KV Jan Mayen marks an important milestone in Norway’s maritime defense strategy. As the first of three new vessels in the Jan Mayen class, it strengthens the Royal Norwegian Navy’s ability to protect its waters, enforce maritime law, and support emergency response efforts.
Powered by Bergen Engines, the vessel combines operational flexibility with sustainable power technology, making it a valuable asset for coast guards worldwide.
