(CNN) -- A disabled freighter and the tug towing it are still on schedule for a Tuesday arrival in Dutch Harbor, Alaska, a U.S. Coast Guard spokesman said Monday afternoon.
Chief Petty Office Dana Warr said the disabled Golden Seas and the tow vessel Tor Viking II have about 150 nautical miles of travel ahead of them despite being just 30 miles south of the harbor as of Monday afternoon.
That's because the ships must pass through a safe shipping lane that will require them to travel northeast, then cut back west and ultimately south before entering the harbor, Warr said.
The 738-foot Golden Seas was traveling from Vancouver, British Columbia, to the United Arab Emirates when it suffered engine trouble Friday morning. The vessel was unable to power through rough waves and was in danger of running aground.
The ship is carrying canola seed used for making canola oil as well as more than 450,000 gallons of crude oil, 11,700 gallons of diesel fuel and 10,000 gallons of lube oil. It is owned by the Greek company Allseas Marine.
The Tor Viking II reached the ship on Saturday and began towing it towards Dutch Harbor.
Rough seas on Sunday forced the captain of the tug to shift course to the south to avoid high seas that could complicate the tow effort.
Although the weather has not improved significantly since Sunday, it has not yet hampered the operation, Warr said.
"Everything's going great," Warr said.
