Barents Sea-class

The Barents Sea Class are chartered vessels from Remøy management. Three vessels in this class are specially built for the Coast Guard's duties. The Norwegian Armed Forces rent the Barents Sea-class vessels from Remøy Management. In service 2005-2008, the contract runs until 2025 - 2028. Three of the vessels in this class were especially built for the Norwegian Coast Guard’s assignments. The hull is a Vik-Sandvik design VS 794 CGV. built by Myklebust Verft. This Wärtsilä Ship Design, VS 794 CGV vessel, represents a new generation of environmental friendly coast guard vessels.

The vessels have a very good environmental profile, since they are equipped with natural gas engines. The machinery consists of four gas engines totaling approx. 3200 kW, and in addition a diesel main engine is 4000 kW. It gives the vessel towing power of 101 tonnes. For the crew, gas operation means less noise on board. The Coast Guard expects a 90% decrease in NOx fume releases, and a 20% decrease in CO2 releases compared to a conventionally powered vessel of similar size. It also provides a 25% reduction in fuel costs.

Coast Guard states that at LNG operation in 85% of the time, diesel consumption is reduced by 1230 tonnes. When combusting 1 ton of diesel, it releases 3.15 tonnes of CO2, while in the case of LNG emissions are reduced (about 24%). Similarly, NOx emissions are 68 kg for 1 ton of diesel, and the reduction here is approx. 90% when using LNG. Annual reduction per ship is calculated at 930 tonnes of CO2 and 75 tonnes of NOx.

The ships are built according to VS 794 CGV design. It is said that in the design of the vessel type, the Coast Guard's needs have been emphasized and all the tasks that the Coast Guard will perform for other agencies, such as the Directorate of Fisheries and the Coastal Administration. The vessel has a tank for collecting oil at approx. 1075 m3 and can also operate fire extinguisher. The vessel is armed with a 40 mm cannon as main head. This weapon shall, when not in use, be lowered below deck.

The hull is built along the lines of the North Sea trawler Libas. This is a proven Wärtsilä ship design, and one that maximizes fuel-efficiency and speed. This allows the vessels to perform up to a speed of approx. 16.5 knots using gas generators, up to 18.5 knot mechanically, and above 18.5 knots in hybrid mode. The CGVs KV Bergen, KV Sortland and KV Barentshav follow the global trends of increased automation and smaller crew sizes.

They have a standard crew of 16, while the onboard facilities can support a maximum crew of up to 40 members. This allows even further savings in operating costs. Spaces are furnished for a total of 40 people and are equipped with conference rooms, gym, hospital, dayroom, fair, offices including one for crypto, operating rooms, rescue rooms and storage rooms. The interior work has been done by Norla Marine, including furniture from VAD and Rovde Møbelfabrikk and Contech panels on interior shots.

Hareid Electrical Engineering has carried out the electrical installations on board and the electronic equipment is a delivery from Emil Langva and SAM Electronics with SAM Electronics Integrated Navigation and Command System NOCOS 65-5. Rolls-Royce has delivered the DP system, while the alarm system is from Kongsberg Maritime.

They are well equipped for oil spill preparedness and have been fitted with booms to handle such tasks. The vessels' tanks can absorb 1000 tonnes of oil collected. They are equipped for fire fighting and have high tearing power. Thus, the coastguard vessels in the Barents Sea class can go directly to a casualties and immediately carry out both towing, fire fighting and oil collection. With oil reserves on board, the vessel can collect about 1,000 tonnes of oil.

The Barents Sea-class vessels are all rigged to embark NATO's submarine management system and can act as a platform for the Navy's underwater vehicle. In addition, also KV "Harstad" rigged the same way.
