Owing to an increase in combustible cargoes, notably lithium batteries in refrigerated containers, VIKING Life-Saving Equipment (Viking) has launched HydroPen Reefer, which it describes as a new version of its ‘drill and spray’ solution for fighting container fires inside the box
According to Viking, the World Shipping Council (WSC) indicated over 11% of inspected containers in 2024 revealed reporting deficiencies. In a release, Viking noted that, despite the insurance industry’s exposure to geopolitical events and high-profile vessel losses last year, the Safety and Shipping Review 2025 from insurer Allianz reported “fires and misdeclared cargo remain the top large-vessel concerns”. The insurer added, “Enhancing fire detection and fighting capabilities is critical, especially as the electrification age progresses.”
Emphasising the risk, Viking pointed to an explosion on a container ship in Ningbo last year, which it said highlighted how reefers are used as insulated units without power to carry hazardous goods, including lithium batteries.
It noted, “New guidelines from the International Safe Containerised Cargo Organisation describe how batteries can ignite if damaged or overheated, triggering thermal runaway reactions that lead to fires or explosions.”
Viking explained that, in contrast to conventional exterior firefighting methods, HydroPen’s drill and nozzle attaches to a ship’s hose and uses water pressure to drill through the container shell and fight fires at source.
The company said its new system addressed concerns related to reinforced reefer doors and thicker insulated walls, which require enhanced drill and spray power.
Viking senior vice president sales Benny Carlsen said, “Many of the larger container operators have adopted HydroPen fleetwide, and many have also recognised the benefit of carrying several units in different locations.”
Viking noted the system can be operated remotely by a single member of the crew once the drill and spray unit is fixed on the container door. It explained that in ‘reefer mode’, the unit is attached directly to a refrigerated container stacked up to lashing bridge height.
