Firefighting teams from Switzer Salvage arrived and brought additional firefighting equipment, including a Cobra cutting extinguisher. The boundary cooling efforts were kept up for the coming week, while nearby containers were cooled and extinguished by various means.
“With the Cobra we could directly and efficiently cool down a number of containers with good result. Especially containers with goods stowed in a way that sufficient volumes of free space would be effectively cooled with the Cobra. For solidly packed containers with materials like textile, etc., giving no free space for gas cooling, the practice of drowning with vast amounts of water seems to be the most efficient method.”, said Willem Nater.

In 2014 a fire broke out a 6,500 ton, 120 metre trawler. The fire was caused by hot work onboard, while the vessel was alongside for maintenance and overhaul.
After briefing, the two Amsterdam cobra units were deployed on boat deck and a Rotterdam cobra unit.
Amsterdam crew used one cobra unit from the forward part of the superstructure, moving aft in steps of approximately 2 meters at the time, cooling off/extinguishing each compartment. When reaching the aft part of the superstructure at boat deck level, the Amsterdam team attacked the upper deck above in similar way, moving forward. The fire was extinguished.

CONCLUSIONS
Following regulatory requirements from SOLAS, i.e. a water mist system is mandatory on container ships after 1st January 2016, implementation of water mist should be seen as a tool-in-the-box that allows joined up techniques when firefighting to use the most optimal approach to combat fires. Understanding the bigger picture as to where water mist can have best effect across a vessel and its cargo is imperative. As more vessels use such systems, case studies should be shared, and techniques and products developed. Also, looking back at historical events will enable systems integrators to second guess where issues may arise and set standard operating procedures to cover those eventualities.
We believe the Cobra method will have a significant impact in this market.
