Design and analysis of CO2 offshore storage and injection facilities

Abstract

This study proposed CO2 intermediate storage and injection facilities for ship based CCS to solve ship`s flexible transport system, economy and geological reservoir condition problem. Using this concept, proposed many design alternatives. Proposed design alternatives were total 4, floating ISIF*, hanging ISIF, submerged TLP ISIF and seabed ISIF. Floating ISIF was structure which CO2 storage tank location was on the sea level, and hanging ISIF was storage tank hanging on the floater. Submerged TLP ISIF was modified existing TLP to storage CO2 into middle of the sea, finally seabed ISIF was storage tank installed sea floor. Conceptual design did each design alternative. And based on conceptual design of design alternatives, through the evaluation process take one practical design solution. Final goal was did detailed design process of practical design solution.
