The ship is 120 meters long and is located off Storesand at Skjærhalden. Police say there is an explosion-like fire on board the ship, but no one is believed to have been injured.
"We have resources on the way. It is an unclear situation with the fire, but the crew of 15 people is under control," says on-duty rescue leader Asbjørn Viste to NTB.
Police told NRK that an explosion has occurred on board.
According to police, a rescue helicopter, police boats, and medical and fire personnel have been deployed, but the ship has not requested evacuation.
We will assist with whatever they need, says Asbjørn Viste.
