    摘要： The present invention relates to a marine riser isolation tool in particular to an autonomous marine riser isolation tool having a robotic plug installation device that is adapted for positioning a pipeline isolation plug in a vertical pipe such as a marine riser, resulting in sealing of the marine riser. In one aspect of the invention, there is provided an autonomous plug installation device that is suitable for installing an isolation tool in a marine riser, the plug installation device comprising; a hydraulic ram system comprising a plurality of pipe engaging means positioned along an exterior surface of the hydraulic ram system, the pipe engaging means being operable by the hydraulic ram system to be movable between a retracted and extended configuration such that the pipe engaging means are engagable with the interior surface of the marine riser; a control system in communication with the hydraulic ram system to control the movement of the pipe engaging means such that the robotic unit locates the pipe isolation tool at a predetermined location in the vertical pipe; and an autonomous ELF communications system. A method of sealing a leaking marine riser using the marine riser isolation tool is also disclosed.

    摘要： An hydraulic system for an autonomous multi-set pipeline isolation tool comprising an hydraulic piston; a pump for operating the pistons; an accumulator between each of the hydraulic pistons and the pump; and means for operating the pump. The system also comprises a manifold operable to control the flow of fluid in fluid pipelines to control the operation of the pistons which actuate gripping and sealing means of the autonomous multi-set pipeline isolation tool. The hydraulic system further comprises a controller comprising a number of operational modules which are positioned on a single printed circuit board. The advantage of this is that the size of the hydraulic system may be minimised thereby enabling use of the system within a pipeline having an inner diameter of the order of 0.15m (6") and upwards. The manifold of the hydraulic system is also provided with a triple fail safe redundancy mechanism.
