The M/S Sigrid

In Sweden, basically all radioactive waste and spent nuclear fuel is transported by water. SKB’s vessel, the M/S Sigrid, picks up waste at the nuclear power plants and transports it to our facilities in Oskarshamn and Forsmark. Low and intermediate-level waste is also transported from the Studsvik Research Center.

Sigrid is specially designed to transport radioactive material. The vessel was built between 2011 and 2013 in Galati, Romania by Damen. The International Maritime Organisation (IMO) has given her the highest classification, level INF 3, for vessels that transport radioactive material. 

Environmental considerations 

Sigrid is equipped with extra communication equipment, and has several internal and external safety improvement functions. For example, many crucial systems are duplicated and separated to promote high operational availability and flexibility. If an important system fails during a journey, for example due to a mechanical error or an accident, a reserve system will take over.

Environmental considerations have had high priority when designing Sigrid. For example, she operates on low sulphur marine diesel, and thanks to the engine arrangement with four slightly smaller main engines, she can take advantage of catalytic exhaust purification even at low speeds.

Sigrid is loaded and unloaded by the ro-ro method, which means that terminal vehicles drive via a ramp off the stern into the cargo hold where they load and unload transport casks.

Sigrid is owned by SKB, but Furetank Rederi AB will handle operation and staffing.
