Filed:

May 14, 2019

Appl. No.:

16/412075

Inventors:

- Houston TX, US
Sam Almerico - The Woodlands TX, US

Assignee:

Oceaneering International, Inc. - Houston TX

International Classification:

F16L 53/38

Abstract:

External heating assembly is usable to heat subsea flowline and remediate a blockage in subsea flowline and comprises a predetermined set of heaters ; one or more conductive layers configured to uniformly distribute heat over an exterior of subsea flowline ; one or more insulating layers adapted to shield subsea flowline , the predetermined set of heaters , and conductive layers from ambient seawater temperature; an anchor; and a strength member. The predetermined set of heaters may comprise one or more mineral insulated cables capable of reaching very high temperatures with very little power and minimal controls.

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 wellbore/pipeline 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.
