摘要： Hydrostatic test tool comprises frame; pressurizer; connection system; control system; data communicator; power supply; device handler; and buoyancy unit. Hydrostatic test tool can be used to perform an in situ seal test of subsea equipment connectors with limited support from external systems, allowing optimization of subsea operations by not requiring constant support from underwater vehicle, which could be used to perform other tasks while the test is being carried out, optimizing the total time of support vessel and reducing operational cost. Hydrostatic test tool typically requires interfacing with underwater vehicle, e.g., an ROV or AUV, only for deployment/installation and data communication, if at all.

摘要： A method of installing a subsea pipeline for tie-in to a subsea structure. The method comprises laying, using a pipe laying vessel, an intermediate section of the pipeline on to a pipe restraint device, wherein the pipe restraint device is at or near the subsea structure, or is at or near a location at which a subsea structure will be installed, and the pipe restraint device restricts transverse movement of the pipeline. The intermediate section of the pipeline is configured to be tapped at or near the pipe restraint device for providing fluid communication between the pipeline and the subsea structure.

摘要： The invention relates to joining pipes on water, and more particularly, the present invention relates to an arrangement and a method for joining pipes on water without letting water to get into the pipes. Joining pipes on water, so that water does not get into the pipes is very difficult. The present invention for joining pipes on water comprises a vessel (102) arranged to float, which comprises a joining space (104) having an open upper part (106), at least two opposed openings (108) for arranging the end of the pipes to be joined inside the joining space (104), and respective closing parts (110), which can be arranged in the openings in order to close the opening (108), when the pipe end is in the joining space (104). The arrangement comprises altering means for altering a carrying capacity of said vessel by adjusting the ratio of water and air in the joining space.
