Echochlor, which represents the NanoVapor Vapour Suppression System in the maritime industry, reports that the system has received a product type approval certificate from Lloyd’s Register (LR).

The portable ST-1000 system weighs 45kg, has no moving parts, and is powered by compressed air. When used with its proprietary liquid nano-suppressant, the ST-1000 delivery unit is claimed to quickly gas free a tank up to 90% faster, even if residual fuel or sludge is present. Since normal oxygen level is preserved throughout the suppression process, the confined space is quickly made safe for entry. Only a tiny amount of the non-toxic and biodegradable nano-suppressant is needed, leaving no residue or waste to clean up.

Russell Chew, NanoVapor CEO, said: “Our vapour management systems have been fully tested and successfully adapted for high speed gas freeing of fuel and petrochemical tanks of all sizes. The LR Type Approval now opens the door to extend our recognition as a ‘Best Practice’ gas freeing system for land-based tanks to vessels.”

Ecochlor VP Business Development Andrew Marshall said that this nanotechnology will “revolutionise tank cleaning and gas freeing of cargo and bunker tanks in preparation for dry dock or unplanned tank inspections or maintenance.”

With regard to the IMO 2020 sulphur cap, the NanoVapor technology can be used to facilitate faster bunker tank cleaning procedures and allow vessels to resume normal operation as quickly as possible.
