Accidents

An Tai Jiang (2009)

A main-engine crankcase explosion caused an engine-room fire on the asphalt tanker An Tai Jiang. The fire spread into the accommodation spaces, killing two crew members; a third motorman was lost at sea.

Classification

  • Incident Type: Fire
  • Severity: High

The Hong Kong Marine Department identified the crankcase explosion as the most probable cause and found major safety-management non-conformities.

Key facts

  • An Tai Jiang, a Hong Kong-registered asphalt tanker with 25 crew, was carrying 4,080 tonnes of asphalt from Ulsan to Ningbo when the fire occurred at about 12:30 local time on 9 January 2009.
  • The Hong Kong Marine Department identified a main-engine crankcase explosion as the most probable cause. Hot oil mist and/or flammable vapour ignited and the fire spread from the engine room into the accommodation spaces.
  • The report confirms the deaths of the Third Engineer and one motorman. A second motorman fell into the sea and was recorded as lost at sea; the web report does not document recovery, so the page records one missing person.
  • The crankcase oil-mist detector and engine-room fire alarm system were defective. The fire caused serious damage to the engine room and accommodation, but the investigation found no oil pollution.
  • The crew was evacuated or rescued from the lifeboat, salvage tugs extinguished the smouldering fire, and the vessel was towed to Ningbo on 11-13 January.

Narrative

An Tai Jiang loaded 4,080 tonnes of asphalt at Ulsan and departed for Ningbo on 7 January 2009. At about 12:30 local time on 9 January, while the vessel was under way about 120 nautical miles east of the mouth of the Changjiang River, the Second Officer saw dense smoke at the funnel and was told that the main-engine exhaust duct was on fire. The engine was stopped, but the fire spread rapidly from the engine room into the accommodation spaces.

The Hong Kong Marine Department's investigation identified a main-engine crankcase explosion as the most probable cause. It found that the oil-mist detector and fire-detection system had failed to alert the engine-room crew at an early stage. The report also found that the port engine-room door did not contain the fire effectively and that firefighting, rescue, training, equipment maintenance, and safety-management implementation were inadequate.

The crew attempted boundary cooling and released carbon dioxide, but the linked release system was disconnected and the gas had to be released manually. At about 13:00 the port lifeboat was lowered, but its propulsion engine did not start. The Master ordered the crew back at about 13:30; seven remained in the boat. When its mooring ropes parted at about 14:43, two people fell while trying to reboard. One trainee was recovered, while a motorman was lost at sea. The three people who remained in the lifeboat were later rescued by a Korean cargo ship.

The salvage tug Dong Hai Jiu 112 arrived at about 21:30. The salvage team extinguished the smouldering fire on 11 January, when the bodies of the Third Engineer and another motorman were found. Two tugs then began towing An Tai Jiang to Ningbo, where she arrived on 13 January. The report recorded serious damage to the engine room and accommodation and no oil pollution.

The investigation therefore confirms two deaths and records one motorman lost at sea. It does not document recovery of that person, so the page keeps the casualty split as two fatalities and one missing person.

Contributing factors

FactorEvidence statusDescription
Main-engine and lubrication-system problemsSuspectedThe Hong Kong Marine Department identified a long-standing problem in the main engine and lubrication system and a crankcase explosion as the most probable cause.
Defective detection and containment safeguardsConfirmed findingThe oil-mist detector and engine-room fire alarm failed; the port entrance door might have failed to close or might not have been properly closed, allowing the fire to spread.
Inadequate emergency training and leadershipConfirmed findingThe investigation found no fire or abandon-ship drills for the three months before the casualty, false drill entries, poor firefighting coordination, and weak leadership.
Poor maintenance of lifesaving and firefighting equipmentConfirmed findingThe lifeboat engines, emergency fire pump, quick-closing valves, and carbon-dioxide release arrangement had material defects or maintenance problems.

Investigation

The Hong Kong Marine Department report of investigation, Preliminary Inquiry No. 1 of 2009, investigated the engine-room fire. It identified a main-engine crankcase explosion as the most probable cause, recorded serious damage but no oil pollution, and made recommendations on equipment maintenance, drills, safety-management audits, and identifying substandard ships.
