The ship that burst into flames on a container ship off the coast of Australia is a hydrofoil container ship, according to Australian Maritime Safety Authority (AMSA).

The vessel was carrying a shipment of palletised cargo from the US and China.

The container ship is not a tanker and was not carrying anything hazardous to the ship, the authority said in a statement on Tuesday.

The cargo ship’s captain is still missing and is believed to have been killed in the fire, AMSA said.

The Australian Maritime Rescue Centre said on Twitter that two people were still missing.

The cause of the fire is not yet known.

The accident is the third cargo ship disaster in three years, according a 2017 report from the Institute of Chartered Surveyors.

In January, a container shipping disaster that killed 29 people on board a container vessel in the port city of Port Hedland, Victoria, killed nine people.

In October, a cargo ship sank in the middle of the night off the Australian outback, killing at least nine people, including two children, the Australian Broadcasting Corporation reported.

The company that owned the container ship said in August that it had made significant changes to safety and operating procedures.
