ClassNK Approves Spray-On Insulation for LNG & Ammonia Tanks
Leading classification society ClassNK has granted approval in principle for a revolutionary new spray-on insulation system designed specifically for LNG and ammonia tanks. Developed by Nihon Shipyard and Hankuk Carbon, this innovative marine insulation method is set to transform fuel tank construction for vessels transitioning to alternative fuels, marking a significant step for the global shipping industry.
Innovation in Marine Insulation Technology
The newly approved system offers a distinct advantage over conventional panel-based insulation, utilizing a spray-form application for IMO Type B fuel tanks. This advanced technique is particularly beneficial for designs requiring larger fuel capacities, such as those found in ammonia-fuelled ships and large container vessels. Its flexibility and efficiency promise enhanced performance and reduced installation complexities for shipbuilding projects.
Accelerating Alternative Fuel Adoption
This ClassNK approval directly supports the maritime sector’s push towards cleaner energy solutions. By providing a robust and approved insulation for LNG and ammonia fuel tanks, the system facilitates the wider adoption of these crucial alternative fuels. ClassNK conducted a thorough safety review based on IGC and IGF Codes, ensuring the system meets stringent international standards, reinforcing confidence in its deployment across the fleet.
This development underscores the shipping industry’s commitment to sustainable operations, paving the way for more efficient and environmentally friendly vessel designs worldwide.
