System for depressurization lines and subsea equipment and method for the removal of hydrate

摘要

System for depressurization lines and subsea equipment and method for the removal of carbohydrate.The present invention relates to a system (1) for venting of the lines and subsea equipment for the production of hydrocarbons in deep water, composed of a system of relief of pressure activated remotely, made possible by a pump (2) which moves a driving fluid ATR Avu00e9s a line (3) to the bottom of the sea.Such fluid drives a driving pump hydraulically activated (7), for example, a pump jet, which despressuriza a stretch of line or equipment sub.This depressurization has several applications including: disconnection and removal of an equipment for the surface to a lower pressure, facilitating the cleaning of the equipment or promote breaking of hydrate in the flow path as in the subsea equipment. And can the realization of cleaning operations of wells injectors through operations of reverse flow of high flow.The system is operated remotely from a production unit not requiring the use of sea boat or probe. This depressurization for disconnection and removal of modules, for example: pumping separation and / or submarine can be carried out in parallel with the production, minimizing losses.
