The vessel to a Canadian Coast Guard ship snapped
Lt. Paul Pendergast of the Canadian Forces' Joint Rescue Co-ordination Centre said the Barbara Foss arrived shortly after 5 p.m. local time, and was securing a line to the Simushir.
"When they get the vessel under tow, they'll first head in a northwesterly direction and get it further from the coastline and eventually into more sheltered waters to the north of Haida Gwaii," Pendergast said. "Then a decision will be made on where to take it."
The ship was adrift again for several hours Saturday after a tow line tethering the vessel to a Canadian Coast Guard ship snapped.
Lt. Greg Menzies of the rescue co-ordination centre said earlier that the crew members were in no danger.
"Right now all 10 crew members are on board," he said. "There's been no request for evacuation."
Two Canadian and one American coast guard ships were also on scene and three helicopters were on stand-by at the closest airport, he said.
The Simushir lost power Thursday night in rough seas west of the Haida Gwaii archipelago, off B.C.'s northern coast. There were immediate concerns it could drift ashore, break apart and spill hundreds of tonnes of bunker and diesel fuelling the vessel, creating an environmental disaster.
