The Gunnerus is a research ship of the Technical and Natural Sciences University of Norway (NTNU) in Trondheim .
General
The ship was built under hull number 41 at the Larsnes Mekaniske Verksted shipyard in Ålesund . The hull was supplied by the Latvian Riga Shipyard. The ship was completed on March 25, 2006. The construction costs amounted to around 40 million NOK . The design of the ship came from the marine architecture office Polarkonsult (project number PK-410).
The ship was christened on March 25, 2006 . Godmother was Oddlaug Digernes, wife of the rector of the NTNU. The ship is named after Johan Ernst Gunnerus , bishop and scientist and one of the founders of the Royal Norwegian Scientific Society . It replaced the previous research ship Harry Borthen , which had been commissioned in 1962.
In 2019 the ship on the Assens Skibsværft was extended by five meters.
The ship, which is approved for coastal travel up to 20 nautical miles offshore, is at sea around 180 days a year. It is used for research in various disciplines of marine science. When it is not in use by the university, it is also available to other research institutions such as SINTEF and Norges geologiske undersøkelse, or it can be chartered by companies.
Technical data and equipment
The ship is equipped with a diesel-electric drive . Three diesel generator sets are available to generate electricity. As motors act three Nogva / Scania - V8 diesel engine (type: DI16 44M), each with 450 kW power that drive three Stamford generators. In many cases, energy production by a generator set is sufficient. The other generator sets can be switched on manually or are started automatically when the previous generator set has reached 80 percent of its output. The propulsion was initially carried out by two Siemens electric motors, each with 500 kW power, which acted on two fixed propellers with Kort nozzles . The end of 2014 the drive was by two Rolls-Royce - azimuth thruster with permanent magnet motors replaced. The propeller nacelles were prototypes that were also installed for test purposes. Replacing the propellers with the propeller pods resulted in energy savings, lower vibrations and less noise.
The ship is equipped with a bow thruster with 200 kW power and has a system for dynamic positioning .
The hull of the ship is reinforced with ice ( ice class C).
The ship has four decks . There are three single cabins for the ship's crew and three double cabins for scientific staff on board . A total of eleven people can be accommodated by using emergency beds. On day trips, 25 people including the three-person crew can stay on board. There are three laboratories on board, a 13.9 m² wet laboratory, an 11.8 m² dry laboratory and a 11.2 m² computer laboratory.
An open working deck is located behind the superstructure . This was initially 75 m² and could be loaded with 45 t. After the reconstruction of the ship, 125 m² of space will be available. The deck can be loaded with 25 t. 5-, 10-, 15- or 20-foot containers can be carried on board . Below the working deck there is a 42 m³ cargo space that is accessible via a hatch . The ship is equipped with several winches . There is a slipway at the stern . A swiveling rear boom that can lift 6 t is also installed here. There is a crane on the working deck. This could lift 35 t. During the renovation in 2019, this was replaced by a crane that can lift 62 t. Another lifting tool is a CTD crane, which is designed for deploying and retrieving a CTD rosette and other research equipment. The ship is set up for the use of an ROV . During the conversion, an ROV hangar was set up which is equipped with its own lifting tool that can lift 4 t.
The ship is equipped with a rigid inflatable boat as a work boat and as a man overboard boat.
