The guidance can be used for the development, manufacturing, and safe installation of such equipment on ships.
In order to reduce GHG emissions from ships, in addition to fuel conversion, there is a growing interest in methods for capturing CO2 from exhaust gases, and the development of equipment to capture and store CO2 onboard is underway. In 2023, the Association published the "Guidelines for CO2 Capture and Storage Equipment on Ships (Version 1.0)," which describes the requirements for CO2 capture and storage equipment on board using the Amine Absorption Act.
The newly published version 2.0 stipulates the requirements to be considered when developing and installing the equipment on ships for CO2 capture and storage equipment using the membrane separation method, which requires less electricity for CO2 capture than the amine absorption method and does not require aqueous amine solution to be maintained.
Furthermore, by reorganising the basic functional requirements required for CO2 capture and storage equipment, ClassNK has extracted common requirements without relying on recovery technology, and summarises them as general requirements that should be applied regardless of the recovery technology method.
