NTSB Report on Vessel Fire Highlights Electrical Safety and Welding Best Practices

The NTSB released its final report on the fire that occurred aboard the Qualifier 105 passenger ship in Alaska in 2023. The fire broke out on January 19, while the vessel was docked at a boat yard in Homer, Alaska, and was contained by local firefighters with no injuries or pollution reported. The vessel, valued at $1.2 million, was declared a total loss due to the extensive fire damage.

Investigators ruled out hot work as the cause of the fire, pinpointing an unknown electrical source that ignited the cabin ceiling. The report emphasized the danger of stray current during welding, explaining that it can lead to fires due to overheating of wires. To prevent such incidents, maintenance personnel, owners, and operators are advised to follow industry best practices and ensure that the welding machine’s return terminal is located as close to the weld as possible.

The NTSB report underscores the importance of proper welding procedures to prevent fires caused by stray current. By following industry guidelines and ensuring the correct positioning of welding equipment, the risk of accidents and damage to vessels can be significantly reduced. The investigation into the Qualifier 105 fire serves as a reminder of the potential dangers present in marine operations and the need for vigilance in maintaining safety standards.
