ABSTRACT

This study estimated the availability of an entire ship-based CCS (Carbon Capture and Storage) chain in the conceptual design stage. Although the availability of the chain is influenced not only by failure of the process equipment but also by other aspects, such as shipping and storing conditions, equipment failure is commonly considered in the conceptual design stage. The factors that affect the availability of a ship-based CCS chain include ship voyage conditions, harbor accessibility, storage tank allowance, and injection rate, as well as the failure rates and repair times of process equipment. Production availability was estimated with a commercial code that is based on the Monte Carlo next event simulation method. The data required for the estimation was collected from commercially available databases and existing studies. For example, OREDA (offshore reliability data) was used to determine the failure rate of process equipment, and the frequency of severe weather conditions was employed to examine permission for a ship voyage. The tendencies of several factors were analyzed through input-output analysis.
