  • Method and system for circulating fluid in a subsea intervention stack
    Patent number: 8684089
    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.

  • Cable connection device
    Patent number: 6733203
    Abstract: A clamping device for a wire or cable (2), the end of which has to be attached in a housing (10) includes two clamping bodies (7, 8) with interacting conical surfaces. One clamping body (7) is arranged for receiving and passing through the cable (2), which has to be secured. The second clamping body (8) is arranged to exert pressure against the first clamping body for frictional securing of the cable. The clamping bodies are arranged in such a manner that when the tension in the cable increases the clamping bodies enclose the cable more tightly. The invention is particularly suitable for tools that have to be lowered into a well by the cable.
