Maritime classification society American Bureau of Shipping (ABS), Daewoo Shipbuilding and Marine Engineering (DSME), and GasLog have entered a joint development project (JDP) agreement to enable carbon-neutral shipping.

Under the agreement, the companies will be involved in the development of an on-board CO₂ capture and storage system (OCCS).

The emissions reduction technology uses the process of absorption, regeneration and separation to return exhaust gas CO₂ to the ship, where it can be stored.

The partnership will design an optimal OCCS for a liquefied natural gas (LNG) carrier, which will be constructed by DSME. With the help of various risk analyses and tests, the system will be verified before installation and operation.

The project also aims to receive ABS approval in principle (AIP) for the OCCS system, which is anticipated to be completed by the first quarter of 2023.

Rules and regulations guidance, as well as technical advice and support for the development of the OCCS, will be provided by ABS.

ABS will also carry out a series of risk assessments and supervise the assessment procedure for the technology’s final AIP.

Last year, DSME secured an order for four LNG carriers from GasLog. These vessels are expected to be delivered sequentially from the first half of 2024.

GasLog will be responsible for the technical requirements to deploy and operate the OCCS.

ABS executive vice-president and COO John McDonald said: “Carbon capture on board is going to be a critical technology in the industry’s push for net-zero. We are proud to be able to use our insight into OCCS to support these industry leaders with this landmark project, which promises to materially advance the adoption of this technology at sea.”

Earlier this month, Korean Register signed a memorandum of understanding (MoU) with DSME for the development of smart and autonomous ship technology.
