Hanwha Ocean Partners with Global Classification Societies for Eco-Friendly Ship Technology Collaboration

Accelerating the Development of Carbon-Neutral Ships

Hanwha Ocean is accelerating its efforts to secure next-generation eco-friendly ship technology by partnering with global classification societies.

On June 3 (local time), Hanwha Ocean announced that it had signed a total of three MOUs for eco-friendly technology cooperation with organizations such as the Korean Register (KR) and Norway's DNV at "Nor-Shipping 2025," which is being held in Oslo, Norway. These agreements are part of a global collaboration for the development of carbon-neutral ship technologies, with the goal of securing technological competitiveness in anticipation of the upcoming era of zero-carbon fuels.

Hanwha Ocean will jointly develop a 150,000 CBM-class ultra-large ammonia carrier with the Korean Register. This vessel will significantly increase transport capacity compared to the current maximum size of 93,000 CBM, representing a proactive response to rising ammonia demand. Ammonia is attracting attention as a representative zero-carbon fuel because it does not emit carbon dioxide (CO₂) when burned. It can also be easily converted into hydrogen, making it an economical means of hydrogen transportation.

Hanwha Ocean and the Korean Register will also pursue the development of a design that relocates the crew accommodation area on LNG carriers from the bow to the stern. This is expected to improve the utilization of rear space on the vessel, enhance the efficiency of mooring facilities, and contribute to energy savings.

With Norway's DNV, Hanwha Ocean will collaborate on the development of technology related to high-manganese steel independent B-type (MCTIB) fuel tanks. By raising the vapor pressure limit inside the tank, this technology optimizes vessels for "cold ironing" environments, where ships are connected to external power while berthed. It also allows for longer residual gas storage time and reduces methane slip, thereby contributing to the realization of carbon neutrality.

A Hanwha Ocean representative stated, "We will strengthen our strategic cooperation with international classification societies to accelerate the early commercialization of eco-friendly ship technology," adding, "Through joint development projects, we will enhance technological reliability and take the lead in setting international standards."
