RV Kronprins Haakon is a Norwegian icebreaking polar research vessel jointly owned by the University of Tromsø (50 %), Norwegian Polar Institute (30 %) and Norwegian Institute of Marine Research (20 %). She was built at Fincantieri shipyard in Genova, Italy, and delivered in 2018.
Development and construction
In 1999, the Norwegian Polar Institute issued a proposal for acquiring a new research vessel to replace the 1978-built Lance, a former fishing and sealing vessel that had been rebuilt as a research vessel in 1992. After a feasibility study was completed in 2007, the design contract was awarded to Rolls-Royce in 2008. The initial design was further developed in close co-operation with the Norwegian Polar Institute and other future users of the research vessel and the Rolls-Royce UT 395 vessel concept was approved by the Norwegian Ministry of Finance in 2011. The funding for the construction of the new research vessel was approved by the Norwegian Parliament and included in the 2013 budget.
On 29 November 2013, the construction of the NOK 1.4 billion (approx. 175 million euro) polar research vessel was awarded to the Italian shipbuilder Fincantieri and the shipbuilding contract was signed on 19 December. The vessel, named Kronprins Haakon after Haakon, Crown Prince of Norway, would be built by Genova-based Riva Trigoso-Muggiano shipyard. Final outfitting and sea trials would be carried out at Fincantieri-owned VARD in Norway.
The first steel for the new Norwegian polar research vessel was cut on 15 June 2015 and the keel was laid on 2 September. Kronprins Haakon, named after the crown prince of Norway, was launched on 3 March 2017 and delivered in April 2018.
Rolls-Royce later used the experience gained from designing the Norwegian polar research vessel to develop the UT 851 PRV concept for the British Antarctic Survey. The vessel, RRS Sir David Attenborough, will enter service in 2019.
With a length of 100.382 metres (329 ft), beam of 21 metres (69 ft) and draft of 8.666 metres (28 ft), Kronprins Haakon is the largest Norwegian icebreaker ever built despite being slightly shorter than Svalbard, the 6,375-ton icebreaking offshore patrol vessel operated by the Norwegian Coast Guard. The research vessel has accommodation for 55 personnel in 38 cabins, including a crew of 15–17. She is equipped with hangar for two small to medium-sized helicopters, but the helipad in the bow is strengthened also for the heavier helicopters such as NHIndustries NH90 operated by the Norwegian Coast Guard and Eurocopter AS332 Super Puma search and rescue (SAR) helicopters based in Svalbard.
Like most modern icebreakers, Kronprins Haakon has a diesel-electric propulsion system. Her power plant consists of two 3,500 kW six-cylinder Bergen B32:40L6 and two 5,000 kW 9-cylinder Bergen B32:40L9 medium-speed diesel engines that produce power for two 5.5 MW Rolls-Royce US ARC 0.8 FP azimuth thrusters and two 1.1 MW bow thrusters. The propulsion system also gives her Dynamic Positioning (DP) Class 1 stationkeeping capability. In open water, she has a maximum cruising range of 15,000 nautical miles (28,000 km; 17,000 mi) and endurance of 65 days at cruising speed. The bollard pull of the vessel is 158 tonnes.
Kronprins Haakon is strengthened for operation in winter ice with pressure ridges and multi-year ice, and in ambient temperatures of −35 °C (−31 °F). She is designed according to International Association of Classification Societies (IACS) Unified Requirements for Polar Class Ships and her ice class, Polar Class 3, is intended for vessels designed for "year-round operation in second-year ice which may include multi-year ice inclusions". A capable icebreaker, Kronprins Haakon can break 1 metre (3 ft) thick ice at a continuous speed of 5 knots (9.3 km/h; 5.8 mph) and maintain a speed of 12 knots (22 km/h; 14 mph) in 0.4 metres (16 in) thick ice.
A high-end research vessel, Kronprins Haakon has an extensive scientific outfit for oceanography, marine biology and geology. The main deck is largely dedicated to scientific activities with 15 fixed and three container laboratories, refrigerated storage rooms, large working deck with cranes and an A-frame for trawling, and a hangar and 3-by-4-metre (10 by 13 ft) moon pool for sampling as well as AUV and ROV operations. Underwater acoustics instrumentation is fitted in two drop keels as well as special "arctic tanks" for operations in ice-covered seas.
