Study shows retrofitting liquid-absorption-based carbon capture and storage system on a Suezmax tanker

In Denmark, a joint study by TMS Tankers Ltd and DNV explored the feasibility of retrofitting a liquid-absorption-based carbon capture and storage system on a Suezmax tanker. The study revealed complex system interdependencies and yielded valuable insights.

study explored how on-board carbon capture and storage (OCCS) technology could be deployed on an existing ship at the lowest possible investment cost (capex). It also examined its impact on other on-board machinery, the decarbonization potential and commercial viability of such an OCCS system on the given vessel. The baseline ship’s operational profile provided by TMS served as a referential data basis. This data was used to optimally fit the net emissions reduction to the trade. DNV applied its modelling suite COSSMOS and the vessel’s digital twin to simulate machinery integration scenarios and estimate the fuel consumption, demonstrating the way the OCCS system affects on-board equipment. DNV COSSMOS stands for Complex Ship Systems Modelling and Simulation. COSSMOS has been extensively used for over 15 years for the assessment of new technologies in shipping.
