The invention discloses a method for injecting carbon dioxide on the sea by using a carbon dioxide transport ship in the technical field of carbon dioxide storage on the sea. The method comprises the following steps that a dynamic vertical pipe is installed between a catenary anchor leg mooring device and a carbon dioxide storage site; liquid carbon dioxide is transported to a sea area above the carbon dioxide sealing site through a carbon dioxide transport ship; a floating hose of the carbon dioxide transport ship is communicated with the dynamic stand pipe jacking pipe; pressurizing the liquefied carbon dioxide to the pressure required by injection through a pressurizing module on the carbon dioxide transport ship, and injecting the liquefied carbon dioxide into a carbon dioxide storage site; and the carbon dioxide transport ship is disconnected from the catenary anchor leg mooring device and is driven away from the sea area above the carbon dioxide storage site. According to the method, offshore carbon dioxide storage can be achieved, large carbon dioxide receiving and injecting facilities do not need to be built on the sea, the investment cost of offshore carbon dioxide storage is reduced to the maximum extent, and the benefits of offshore carbon dioxide storage are improved.

    本发明公开了海上二氧化碳封存技术领域的一种利用二氧化碳运输船的二氧化碳海上注入方法,包括如下步骤:在悬链锚腿系泊装置和二氧化碳封存场地之间安装动态立管;通过二氧化碳运输船将液态二氧化碳运输至二氧化碳封存场地上方海域;将二氧化碳运输船的漂浮软管与动态立管顶管连通;通过二氧化碳运输船上的增压模块将液化二氧化碳增压至注入所需压力并注入二氧化碳封存场地;解除二氧化碳运输船与悬链锚腿系泊装置的连接并驶离二氧化碳封存场地上方海域。本发明不仅可以实现二氧化碳的海上封存,还无需在海上兴建大型二氧化碳接收和注入设施,最大程度降低了海上二氧化碳封存的投资成本,提高了海上二氧化碳封存效益。
