Method and system for circulating fluid in a subsea intervention stack
Abstract:
The present invention relates to a fluid circulation system for circulating fluid in a subsea cavity, the cavity being filled with a first fluid and having first and second end ports. The system comprises a container (26) containing a second fluid, fluid lines (21, 27) extending from the container to the first and second end ports of the cavity, respectively, and a pump (22) for exchanging the second fluid provided in the container (26) and the first fluid provided in the subsea cavity (10). The invention also relates to a method for circulating fluid in a subsea cavity.
Abstract(Chinese):

本发明涉及一种用于在海底空腔内循环流体的流体循环系统，该空腔填充有第一流体并具有第一和第二端口。 该系统包括容纳第二流体的容器（26），分别从容器延伸到空腔的第一和第二端口的流体管线（21,27）和用于更换设置在腔室中的第二流体的泵（22） 容器（26）和设置在海底空腔（10）中的第一流体。 本发明还涉及在海底空腔中循环流体的方法。
