24-meter Ice-class research vessel for Stocholm University


Baltic Workboats has signed in August 2014 contract with Stockholm University for design and building of 24-metre Ice class research vessel. This research vessel will be used mainly for scientific research and educational purposes, but also for different environmental research and monitoring tasks on the Baltic Sea.

Vessel features a large work area for scientists on aft deck from where straight access to laboratory is foreseen. The aft deck will feature a 5-ton A-Frame, 16,5-ton  deck crane, 1,5-ton sampling crane, 3-ton trawling winch and a built in moonpool.

Additionally the vessel will be loaded with research equipment. 12 meter bottom sampling boom will be fastened to the starboard side of the vessel, which can be released and retracted with the A-frame. On the starboard side of the vessel a custom built wave and heave compensated CTD winch with retractable boom will be installed together with Seabird 911plus watersampler. Bottom of the vessel will be equipped with Kongsberg research equipment – EM2040 multibeam echosounder, Topas PS40 sub bottom profiling system, Seapath 330+ system, ADCP, Valeport surface sound velocity sensors  and Splitbeam echosounder EK80. All sensor data will be gathered, stored and analyzed in the apparatus room.

Vessel is designed to provide sufficient accommodation and cozy living areas for total of 6 scientists and crew. The vessel will be able to accommodate these people in four cabins each equipped with separate shower and toilet. However the vessel is built and equipped so that it can carry up to 35 passengers onboard in comfort. The wheelhouse will have forward and aft operating positions, both equipped with controls to maneuver the vessel, navigational information and 360 degree view around the ship. Additionally the vessel will be equipped with two Seakeeper 35 Gyros to keep it stable and operational for scientific work and sailing. Providing 80% roll reduction at 13,5 degree heeling angle.

Propulsion system of the vessels consists of two 368 kW, 1800 rpm Volvo-Penta D16 MH diesel engines connected with shafts to Rolls Royce Aquamaster US 105 FP azimuth propellers, which possess a 1300 mm diameter in a Z-drive configuration. DP system will be installed for easy maneuvering and exact positioning, which is very important for scientific research work. Vessel will have a  top speed above 11 knots. At a service speed of 10 knots, the vessel will have an operational range of over 1,000nm.

Vessel will be built to under supervision of Swedish Transportation agency according to LRS rules notation +100A1 SSC Workboat, Mono, G3, Ice Class 1 C FS, MCH UMS

Delivery of vessel is planned into the end of april 2016.
