ClassNK has issued an approval in principle (AiP) for a methanol fuel tank design concept developed by SRC Group. The certification demonstrates its feasibility from regulatory and safety perspectives.

Ammonia, which does not emit CO₂ during combustion, is expected to see wider use as a zero-carbon fuel for ships.

ClassNK, along with IHI Corporation, JFE Steel, Tohoku University and the Institute of Science Tokyo, have been selected to work on tools assessing stress corrosion cracking (SCC) risks in ammonia fuel storage and transportation equipment.

ClassNK and NAPA, on behalf of all participating organizations, have today announced the successful completion of Phase 3 pilot trials of the cross-industry Digital Twin Project.

The design concept was developed as part of a project exploring the conversion of Tsuneishi's Kamsarmax bulk carrier standard design to a methanol dual fuel configuration.

Since there is no need to cool LCO2 to cryogenic temperatures, it is easy to handle and potentially reduces energy and costs during liquefaction.

When such systems are installed on ships, they are expected to be effective in reducing CO2 emissions through the use of wind power.

Mitsubishi Shipbuilding Co. has jointly developed a large ammonia carrier that uses ammonia as fuel, in collaboration with MOL and Namura Shipbuilding Co., Ltd.

The ship was given an 'A' rating as a 'ship with high decarbonization, environmentally friendly performance, and innovativeness,' recognizing that adequate environment-related investments have been made.

This vessel is jointly developed by Nippon Yusen Kabushiki Kaisha (NYK Line) and LMG Marin AS (a member of the Seatrium Group).

This vessel, if brought to fruition, will be the first bunkering vessel of its kind.

ClassNK has issued an approval in principle (AiP) for a 30,000 m³ LNG carrier equipped with two Mark III Flex membrane tanks, developed by GTT.
