Kronprins Haakon was a long time in the making. The design contract was awarded to Rolls Royce Marine in 2008, but it was not until 2013 that the Norwegian Parliament allotted €145 million for the construction and outfitting of the vessel.


Year-round Operations


Kronprins Haakon is a multi- purpose research vessel built according to the new Polar Code as a PC3 Ice-breaker class ship, suitable for year-round operations in multi-year ice. The Norwegian Polar Institute, the Institute of Marine Research, and the University of Tromsø will use her jointly, mainly in the Arctic, but also in the Antarctic. With its 100 metres (330 feet) in length and 21 metres (70 feet) breadth, the vessel caters for up to 55 persons, including scientists, researchers, students and crew members. It will be a good observation platform for researchers for their work under extreme climate conditions. The ship is a multi-purpose vessel that covers different fields of research work such as stock assessment, oceanography, geophysics, marine biology and marine geology.


The vessel is designed to carry two helicopters, with the helicopter


hangar and the landing platform in the bow area. The vessel is designed with a large open work deck where the stern is formed like a stern trawler. In addition to ‘ice gallows’, trawl winches have been installed for both pelagic and bottom trawling, enabling the vessel to trawl in both open and ice-covered waters. On the port side of the stern there is a hangar for deploying the Hugin AUV.


The work deck also has facilities for seismic operations and a seafloor drill rig, such as the MeBo driller, and with its grid of container fixing points it can deploy, tow and recover a variety of mobile equipment and towed vehicles, using the A-frame installed at the stern.


Handling Equipment


In front of the working deck there is the main hangar, with a 3 x 4m moon pool and opening to the starboard side, for deployment of ROVs such as the Ægir6000, Kley


France Giant Calypso corer and other instruments for sampling the water column or the seafloor. There is also a separate CTD hangar for water samples next to the main hangar. The Norwegian company Seaonics has delivered complete state-of-the-art handling equipment for extreme conditions, and the package includes winches, cursor system for safe moon pool deployment of ROV and scientific equipment, deck cranes, and overboard systems, including A-frames and launch and recovery systems (LARS).


On-board laboratories


Inside the ship there are 15 laboratories for the researchers on scientific cruises, including Wet Geology/Benthos laboratories for analysing coring samples, ice samples and to determine invertebrate species composition, abundance and size from benthic sediments, and an isotopic lab to monitor radioactive contamination (gamma and beta emitters) in the
