The increasing awareness of environmental problems, especially global warming due to the green-house effect by carbon dioxide (CO_2) emissions from fossil fuel burning, is accelerating the study of the countermeasures including the suppression of the increase in the atmospheric CO_2. An alternative among various countermeasures argued is the sending CO_2 into deep sea. In the previous paper, three types of CO_2 transfer system by solid, liquid, and hydrate state, were investigated conceptually refering to the storage and shipping of CO_2 and sending CO_2 into deep sea. Considering the merits and demerits of the three types comparatively, the one for liquid CO_2 was decided to be feasible for further study at present. In this paper, more detailed transfer system for liquid CO_2 is studied. Feasibility study under specific design conditions is performed on storage tank for the recovered CO_2 on land, liquid CO_2 carrier, ocean platform, and pipe for sending CO_2 into deep sea. As a result, the outline of the possible whole figures of the system is clarified. Furthermore, the influencial factors on the system are examined.
