CCS approves new low emission VLGC with CCUS system

China Classification Society (CCS) has issued approval in principle (AiP) to Jiangnan Shipbuilding for a new low-carbon emission very large gas carrier (VLGC) equipped with a carbon capture (CCUS) system, it said on March 28.

In response to the trend of low carbonisation of the shipping industry, Jiangnan Shipbuilding and No. 711 Institute of CSSC jointly developed this VLGC provided with CCUS system in cooperation with CCS.

The conceptual design of this VLGC is based on the LPG dual fuel ship type with the largest cargo capacity in the world, CCS said. Two Type C low-temperature carbon dioxide tanks are provided on both sides of the open deck in the cargo oil area, and the designed carbon dioxide capture rate of the CCUS system can reach over 85%.

CCS said it has conducted in-depth research and detailed assessment on aspects including the overall design, ship layout, carbon dioxide capture and storage systems, ship waste heat utilisation, power load assessment, and ship energy efficiency contribution, and provided all-around technical services in ship safety and system design optimisation.

In addition, CCS has also submitted to the International Maritime Organisation (IMO) the guidelines for the calculation of the energy efficiency design index (EEDI) for a ship installed with the CCUS system based on the working principles and emission reduction elements of the CCUS system, as well as two proposals on revisions to the inspection and certification guidelines.
