A ship carrying thousands of vehicles, including 1,100 Porsches, has been burning since Wednesday. The 22 crew members of the ship have been evacuated. It is now drifting off the coast of the Azores, Portugal, in the North Atlantic Ocean.

The vessel, ‘Felicity Ace’, departed from Emden, Germany, on February 10 and was scheduled to arrive in Davisville, Rhode Island, US, on Wednesday.

The fire broke out in the cargo hold of the ship when it was about 200 miles from Terceira Island in the Azores, a Portuguese island territory. Portuguese forces on Wednesday evacuated the crew soon after the fire broke out.

The rescue operation, involving a chopper, was a “highly skilled and physically demanding” one, the authorities said. The rescued crew members were taken to the nearby Portuguese island of Faial.

So far, it is not clear how much of the 650-foot, 60,000-ton cargo ship’s inventory was lost in the fire. The shipping company could not immediately be reached.
