A Swedish cargo ship designed to haul radioactive waste bumped into a little bit hassle Friday outdoors the harbor of a decommissioned nuclear energy plant in southeastern Sweden.

The Swedish Maritime Administration confirmed that the MV Sigrid had a pilot on board when it ran aground at about 8 a.m. because it approached the Barsebäck nuclear energy plant. The ship was not carrying any harmful cargo, the administration and the ship’s proprietor confirmed. Wind on the time was about 10 to 12 knots.

A tugboat, two coast guard vessels and a ship inspector from the Swedish Transport Agency had been despatched to help the vessel, confirming that no oil was leaking from the ship.

By midday, a tug was in a position to free the Sigrid and pull it into deeper water. Within a couple of hours, divers had been in a position to verify that there was no harm to ship’s hull or propellers.

The reason behind the grounding is beneath investigation.

The nuclear cargo vessel MV Sigrid was delivered in 2013 by Damen’s Galati Shipyard in Romania to the Swedish Nuclear Waste Management Company (SKB). The ship was designed to move radioactive materials from Swedish nuclear energy crops to SKB’s amenities in Oskarshamn and Forsmark. The vessel can transport as much as 12 nuclear waste containers, in addition to customary cargo containers or particular vans.

The Barsebäck Nuclear Power Plant has two reactors which were decommissioned since 1999 and 2005, respectively.
