In January's monthly report, the Swedish Club reports of an incident where a container that although was allowed to be loaded in the cargo hold, it should not have been loaded below deck or in the position it was stowed in, led to a fire.

The Incident

During early morning hours, the Master was at the bridge of the vessel when they observed a large cloud of smoke issuing from the forward part of the vessel. At the same time the fire detection system for cargo hold 3 sounded on the bridge.

According to the Master, the smoke was first white and then greyish. Yet, the Chief Officer, however, described the smoke as being “dark grey, almost black”.

Following, the ventilation fans for the cargo holds were stopped. The fans for cargo hold 3 were not operating at that time but natural ventilation was being provided for the holds as the covers for the vents were open. Crew members closed the covers of the vents for cargo hold 3 and no crew member
entered the cargo hold.

The Master, then, anchored the vessel nearby. After checking the vessel, the Chief Engineer released the contents of almost 200 CO2 cylinders into cargo hold 3. This discharge was the designated full complement of CO2 required for the hold, and appeared to extinguish the fire. A couple of hours later smoke began to issue from the hold and a further 50 CO2 cylinders were released into cargo hold 3. About six hours later smoke was observed issuing from cargo hold 3 and the Chief Engineer released a further 50 CO2 cylinders.

The next morning, salvors boarded the vessel to better check the vessel. Shortly before midnight, temperature checks were completed by the vessel’s crew indicating that the temperature in cargo hold 3 was rising so five more CO2 cylinders were released.

In the morning, another 20 CO2 cylinders were released. The salvors entered cargo hold 2 and measured the temperature for the bulkhead to cargo hold 3 - it was 80°C. It was decided that cargo hold 3 should be filled with water from the fire hydrants. The water filled three container tiers up and after a couple of hours the salvors considered the fire to be extinguished.

It is stated that the container where the fire started was not declared as dangerous cargo but was actually loaded with calcium hypochlorite and had been mis declared by the shipper. The charterer had loaded the container as per the rules of the IMDG code. As per the manifest, the container was allowed to be loaded in the cargo hold, but as the cargo was calcium hypochlorite it should not have been loaded below deck or in the position it was stowed in.
