This study estimated the availability of a ship-based carbon capture and storage (CCS) chain to investigate which would be critical components in the chain and to suggest improvement methodology for design and operation. Bo-ryeong coal-fired power plant and Ul-leung basin in South Korea are designated as the target CO2 emission source and the CO2 storage sink, respectively. The CO2 emitted from the power plant was transported by a CO2 carrier to an intermediate storage terminal and then the CO2 is moved to the basin by offshore pipeline. The ship-based CCS chain contained a capture system, a dehydration system, a liquefaction system, temporary storage tanks, a cargo handling system, a CO2 carrier, and a pumping system. The availability was estimated with the commercial code, TARO, based on the Monte-Carlo simulation method. Firstly, a chain configuration was defined for the availability estimation. Factors that might potentially cause production loss during the operation were identified, and those failure frequencies and restoration times were collected from the available literatures. Finally, the availability of the chain was evaluated. The results showed that the most significant factor was the preventive maintenance for the liquefaction system. The minor factor was a ship engine system. The tendencies of several important factors were analyzed through a sensitivity analysis.
