Abstract
Dynamic/static sealing of coiled tubing subsea for pipeline and well access with hydrostatic conditions up to 10,000 feet water depth while maintaining wellbore or pipeline pressures up to 10,000 psi may be achieved using a system comprising a subsea fluid source which utilizes a riserless open water coiled tubing system and an open water coiled tubing sealer to control hydrostatic pressure and fluid container pressures. This comprises an upper well control assembly having a first geometric orientation and a lower well control assembly in fluid communication with the upper well control assembly aligned in a second geometric orientation substantially inverted to the first orientation; a quick disconnect connector in fluid communication with the upper well control assembly; one or more electrically powered subsea assist jacks operatively connected to the quick disconnect connector; a controller operatively in communication with the electrically powered subsea assist jacks; and a power connector operatively in communication with the source of electrical power, the controller, and the electrically powered subsea assist jack.
