R.V.I.B. Oden Oden Class 1 Icebreaker Delivered 1989 Oden is one of seven icebreakers operated by the Swedish Maritime Administration. Designed for escort ice-breaking and for Arctic research operations, it can carry scientific equipment, container labs, containers, and deep drilling equipment for geological purposes. Length: Draft operation: 110 m 7.0 – 8.5 m Max beam: Max displacement: 31 m 13,000 tons Two 4.5 m variable pitch propellers; equipped with two 28 m2 rudders. The maximum rudder angle is 70°, making it possible to pivot around a point. Jet thruster / hull grease system: 2 centrifugal pumps, 9,000-11,000 m3 h-1 Propulsion/power plant: 4 medium speed 8-cylinder diesel engines Total power: 18.0 MW (24,500 hp) Heeling system: 2 tanks, working volume 800 m3, 2 propeller pumps, 45,000 m3 h-1 each. The pumps transfer all of the heeling water in 15 s. Icebreaking capability: Turning radius in 0.8 m ice: Speed in open water: Endurance: At least 1.8 m ice at 3 knots 1 ship length 16 knots 30,000 nm at 13 knots or 100 days Scientists Laboratories Lab containers: CTD winch: Maximum 50 (usually far less) Wet and dry lab, clean room 11 (maximum) 6,000 m wire Previous expeditions 1991, 1996, 2001, 2002, 2004, 2005, 2007, 2008, 2009, 2011, 2012, 2014: Arctic Ocean (Five times to the North Pole) 2006, 2007, 2010: Antarctic Have included physical, geological, biological and chemical studies Strengths • Excellent ice breaking capability • Underway seawater system • Clean room for trace metal studies • Advanced multibeam system Limitations • Limited station keeping in open water • Limited permanent science gear • Limited deck and technical help Possible Science Objectives: Climate Change and the Arctic • Role of sea ice in air-sea exchanges of climate active gases • Arctic Ocean acidification – effects on biogeochemistry and biological processes • Linkages between terrestrial and oceanic processes • Winter oceanographic processes in the Arctic • Atmospheric transport of contaminants • Biological responses to loss of ice cover on all scales
