Chugoku Marine Paints, Ltd. (Tokyo: 4617; President & CEO: DATE Kenshi) and Mitsui Chemicals, Inc. (Tokyo: 4183; President & CEO: HASHIMOTO Osamu) are pleased to announce that CMP NOVA 2000 (Bio), a bio-based epoxy resin paint developed by Chugoku Paint that has gained ISCC PLUS*1 certification using the mass balance method*2, has been selected for use on the ballast tanks*3 of liquefied ammonia tanker being built by Kegoya Dock Co., Ltd. (Kure, Hiroshima; President: KURUSHIMA Masayoshi).

This paint uses Mitsui Chemicals' bio-based epoxy resin, which has been certified by ISCC PLUS using the mass balance method to reduce CO2 emissions.

Research by Chugoku Marine Paints suggests that this will be the first time in the world that bio-based epoxy resin paint has been adopted for marine vessels.

In addition, the tanker’s bottom is coated with Chugoku Marine Paints’ fuel-efficient anti-fouling paint SEA PREMIER 2000 PLUS, which is expected to reduce CO2 emissions during operation. The adoption of these high-value-added paints is expected to significantly reduce CO2 emissions during paint production and after the vessel enters service. The vessel is scheduled for delivery in May 2026.

CMP NOVA 2000 (Bio) Bio-based Epoxy Resin Paint

CMP NOVA 2000 (Bio) is a bio-based epoxy resin paint for ballast tanks that has been ISCC PLUS-certified and is made from epoxy resins derived from biomass using the mass balance method being rolled out by Mitsui Chemicals. Delivering the same level of quality and coating performance as petroleum-derived products, the new paint maintains functionality, while its biomass-derived content offers the ability to reduce CO2 emissions by approximately 660 kilograms per ton of paint (provisional value) compared to the existing CMP NOVA 2000.

 SEA PREMIER 2000 PLUS Fuel-Efficient Antifouling Paint

As ammonia is attracting attention as a next-generation low-carbon energy (next-generation fuel), the shipbuilder is proactively choosing products with high environmental performance for use in the new vessels. The adoption of SEA PREMIER 2000 PLUS fuel-efficient antifouling paint is expected to improve fuel efficiency by 5 to 8 percent compared with conventional antifouling paints, thereby reducing CO2 emissions during ship operation.

Switching to bio-based paint using the mass balance method has the effect of reducing CO2 emissions by approximately 660 kilograms (provisional value) per ton of paint.

fuel-efficient anti-fouling paint

The smooth coating reduces friction resistance, while the new anti-fouling agent Selektope™, which has high barnacle resistance, substantially minimizes power increases arising from ship bottom fouling. Together, these effects are expected to reduce fuel consumption by 5 to 8 percent, thereby reducing CO2 emissions.

Tankers and cargo ships are stable when loaded, so after unloading their cargo, buoyancy causes them to float high above the sea surface, making them less stable. This tank fills with seawater to replace the cargo, helping to maintain the stability of the ship.
