Svea is Sweden's new oceangoing research vessel, she is especially adapted for research and environmental monitoring in the Baltic Sea, Kattegat, Skagerak and Öresund. Svea was built 2017-2019 by Armon Shipyards in Vigo, Spain, and has been designed by Skipsteknisk AS in Ålesund, Norway. The vessels main activity is ecosystem investigation with a focus on recurrent monitoring of fish stocks and water quality, by SLU and SMHI.

The vessel is also used for

  • data collection for studies and understanding of climate change effects
  • mapping and monitoring of marine biodiversity
  • mapping and monitoring of eutrophication
  • measurements of CO2 and the resulting acidification of the oceans
  • measurements of oxygen and de-oxygenation of the oceans.

Environment and noise

In order to avoid disturbing fish and other organisms in the sea, and to minimize interference with the sensitive sonars, Svea is built to minimize radiated noise from the ship in accordance with recommendations from the International Council for the Exploration of the Sea (ICES 209).

The vessel is as environmentally friendly as possible with the technology that is commercially available today, for example

  • by using renewable HVO-diesel to run the diesel generation plant
  • the work boat's outdoor motor runs on diesel to minimize fire hazard and allow usage of HVO-diesel
  • a large scale particle filter and urea to minimize emissions of particles
  • the hull is painted with a silicone based paint that minimizes fouling without any toxic substances
  • black water and grey water is cleaned in an sewage treatment plant and subsequently stored in a black water holding tank. Water from laboratories will also be led there. The water in the holding tank is so clean that it can be discharged into the sea anywhere. But Svea's sewage water will be emptied into Lysekil municipal sewage system when Svea is in here home port
  • Svea's ballast water is cleaned, i.e. micro organisms will be killed, when the ballast tanks are emptied
  • heat exchangers use sea water for cooling
  • Svea is connected to district heating and the electricity grid in the home port Lysekil
  • sustainable Elondo wood has been used on the work deck
  • specific chemicals and substances are banned
  • textiles are eco-labeled.

A requirement in the procurement process was that the shipyards had to be environmentally certified according to ISO 14001. 

Call sign and MMSI

  • Call sign: SEYB
  • MMSI: 265009000
  • IMO: 9829332
  • The scientific work boat's MMSI is 265813630

Every vessel is assigned a call sign to be used in all voice communication over radio.

MMSI stands for Maritime Mobile Service Identifier and is a number that identifies the specific ship.

The IMO number is a unique ID number that is assigned to propelled, sea-going ships of 100 GT and above, with some exceptions. The number is never changed and never reassigned to another ship.
