Cause Of Fire Aboard Fishing Vessel Blue Dragon Determined By NTSB

The National Transportation Safety Board issued Marine Investigation Report 22/20 Wednesday, for its investigation of the Nov. 10, 2021, fire aboard the fishing vessel Blue Dragon.

No injuries or fatalities were reported in connection with the fire that resulted in more than $500,000 in damages to the vessel. The Blue Dragon was under way conducting longline fishing operations in the North Pacific Ocean when the vessel caught fire. The six crewmembers and a National Marine Fisheries Service (NMFS) observer unsuccessfully attempted to fight the fire. They abandoned the vessel and were rescued by a Good Samaritan vessel. The Blue Dragon was later towed to San Pedro, California.

On Oct. 25, 2021, the Blue Dragon left Honolulu, Hawaii, to fish for swordfish and tuna. On Nov. 9, while the crew were preparing to retrieve fishing gear, the NMFS observer discovered a fire in the wheelhouse under the console. While the crew was attempting to fight the fire, the NMFS observer and a deckhand retrieved the 10-person life raft and the vessel’s Global Navigation Satellite System-enabled emergency position indicating radio beacon (EPIRB) from above the wheelhouse. The NMFS observer used his satellite emergency notification device (SEND) to send an SOS along with a text that said “fire.” He also manually activated the vessel’s EPIRB and his personal locator beacon.

NTSB concluded that the observer and deckhand contributed to the survival of the crew by retrieving the EPIRB and life raft before they caught fire. The observer’s activation of the vessel’s EPIRB and use of his NMFS-issued personal emergency communications equipment further contributed to the crew’s timely rescue, since the equipment transmitted the crew’s location.

The NTSB determined the probable cause of the fire aboard the Blue Dragon was from an unknown source, likely electrical in nature, which ignited the wooden wheelhouse console. Contributing to the extent of the fire damage was the substantial use of combustible materials in the joinery, outfitting, and furnishings in the wheelhouse and accommodation spaces.

NTSB identified two lessons learned from this investigation:

  1. Substandard electrical installation and outfitting—including bare wires, unsecured wire nuts, overloaded circuits, loose wiring, and household wiring not designed for marine use—is a common cause of shipboard/vessel electrical fires. Additionally, batteries have been identified as ignition sources of fires in multiple modes of transportation. Vessel operators should ensure electrical systems are adequately designed, installed, and maintained in accordance with established marine standards to prevent fires.
  2. Personal locator beacons helped validate the position of the vessel’s emergency position indicating radio beacon, and a SEND helped responders identify the nature of the emergency. Vessel owners and operators can enhance the safety of their crews by equipping their vessels and crews with these additional satellite technologies to supplement EPIRBs.

NTSB issued a safety recommendation to the U.S. Coast Guard to require the use of personal locator beacons to enhance chances of survival following the sinking of the cargo vessel El Faro in 2015. All 33 crewmembers perished in the sinking. NTSB reiterated the recommendation after the fishing vessel Scandies Rose sank off Sutwik Island, Alaska in 2019. Two of the vessel’s crewmembers were rescued; the other five crewmembers were never found. NTSB concluded that personal locator beacons would aid in search and rescue operations by providing continuously updated and correct coordinates of crewmembers’ locations. The recommendation remains open.

Improving fishing vessel safety remains a priority for the NTSB and it is an issue on the NTSB’s 2021-2022 Most Wanted List of Transportation Safety Improvements. The NTSB advocates for new standards to address—and periodically reassess—intact stability, subdivision, and watertight integrity in commercial fishing vessels up to 79 feet long as well as personal locator beacons for crew.

Marine Investigation Report 22/20 is available online.
