A 38000 deadweight ton oil tanker is loading methanol. After completing the first step of loading all pre loaded cargo compartments, start full loading towards the left and right compartments 1, 2, and 6. According to the loading plan, when the loading capacity of the left and right compartments of No. 6 reaches 800 tons per compartment, it will be transferred from No. 6 compartment to No. 5 compartment for loading. At 2:30, about 30 minutes after the transfer, a sailor on deck reported that the P/V valve in left hold 1 was on fire. The ship immediately contacted the dock and stopped loading operations. Within 7 minutes after reporting the fire, the personnel on board closed the oil delivery valves in the left and right compartments of No. 1 and No. 2. Shortly after, explosions occurred in the left and right cabins of No.1 and No.2, followed by explosions in the left and right cabins of No.5 and No.6, resulting in the death of five crew members and constituting a constructive total loss (CTL) of the ship.

CCTV surveillance footage shows that due to lightning strikes, the P/V valves in left and right cabins 1 and 2 caught fire. According to paragraph 26.1.3 of the International Safety Guide for Oil Tankers and Terminals (ISGOTT) fifth edition, loading recommendations for thunderstorm weather: When thunderstorms are expected to occur near oil tankers or docks, regardless of whether the cargo loaded on the vessel is inert or not, the following operations must be stopped: handling volatile oil, or handling non volatile substances in non hydrocarbon vapor free compartments. We can find similar but not entirely consistent recommendations in the "Tanker Safety Guidelines (Chemicals)" prepared by the International Chamber of Shipping (ICS). Although the shipping company's safety management system document (SMS) reminded the crew to monitor weather conditions and stop loading and unloading operations during thunderstorms, the sudden thunderstorm caught the crew off guard. The P/V valve and flame arrester also failed to prevent flames from entering the cargo hold (note: According to the revised standards for the design, testing, and positioning of equipment to prevent flames from entering the cargo hold of oil tankers, as stated in paragraph 1.2.7 of the International Maritime Organization Maritime Safety Committee Circular No. 677 (MSC.1/Circ. 677): "These standards do not apply to situations where the fire source is lightning... During thunderstorm weather, all cargo loading and unloading, tank cleaning, and ballasting operations should be suspended ）.
