A CARGO ship that had been delivering new vehicles to Mexico sank in the North Pacific Ocean, weeks after crew members abandoned ship when they couldn't extinguish an onboard fire that left the carrier dead in the water, reports CBS.

The Morning Midas sank last Monday in international waters off Alaska's Aleutian Islands chain, the ship's management company, London-based Zodiac Maritime, said in a statement.

The Coast Guard said it received a distress alert June 3 about a fire aboard the Morning Midas, which then was roughly 300 miles southwest of Adak Island.

"There is no visible pollution," said Petty Officer Cameron Snell, an Alaska-based US Coast Guard spokesperson.

"Right now we also have vessels on scene to respond to any pollution."

The Coast Guard said that the vessel reportedly had 350 metric tonnes of marine gas oil and 1,530 metric tonnes of very low sulphur fuel oil onboard.

Fire damage compounded by bad weather and water seepage caused the carrier to sink in waters about 16,400 feet deep and about 415 miles from land, the statement said.

The ship was loaded with about 3,000 new vehicles intended for a major Pacific port in Mexico. It was not immediately clear if any of the cars were removed before the vessel sank.

A salvage crew arrived days after the fire disabled the vehicle.

Two salvage tugs containing pollution control equipment will remain on scene to monitor for any signs of pollution or debris, the company said.

There were 22 crew members onboard the Morning Midas. All evacuated to a lifeboat and were rescued by a nearby merchant marine vessel. There were no injuries.
