An explosion followed by a fire occurred on 10 August aboard the 124-meter chemical tanker Bergstraum (IMO 9108740) while the vessel was in the Skagerrak near Hvaler, Østfold, Norway. The tanker was carrying sulfuric acid, prompting an immediate response from Norwegian emergency services.
According to preliminary reports, repair work was underway in the forward section of the vessel. During welding operations, flammable vapors ignited, causing a powerful explosion and subsequent fire. The blast was strong enough to rip heavy steel doors from their hinges, demonstrating the force of the explosion.
Despite the severity of the incident, all 15 crew members escaped without injuries. Rescue helicopters, patrol boats, firefighters, and other emergency units were quickly dispatched to the scene. Firefighters used foam to extinguish the fire, while water was continuously applied to cool the hull and prevent the flames from spreading.
The fire was brought under control later the same day. Authorities confirmed that there was no leakage of sulfuric acid and no signs of environmental pollution. The vessel remained stable throughout the emergency operation.
The incident highlights the importance of strict hot work safety procedures aboard chemical tankers. Welding and other maintenance activities require careful gas testing, proper ventilation, and continuous monitoring to prevent explosions caused by flammable vapors. Norwegian authorities have launched an investigation to determine the exact cause of the accident and whether additional safety measures will be recommended.
