CONTAINMENT SYSTEM AND A METHOD FOR USING SAID CONTAINMENT SYSTEM

摘要

A containment system for recovering hydrocarbon fluid from a leaking device comprising a dome sealed to the seafloor around the leaking device and forming a cavity for accumulating hydrocarbon fluid. The dome comprises an upper output opening for extracting the hydrocarbon fluid, and an over pressure valve for extracting fluid out from the cavity to the environment if pressure inside the cavity is too high.

主权项

1. A containment system for recovering hydrocarbon fluid from a leaking device that is situated at the seafloor and that is leaking hydrocarbon fluid from a well, wherein the containment system is adapted to be landed at the seafloor corresponding to a base level of the containment system, and
wherein the containment system comprises a dome intended to be sealed to the seafloor around the leaking device and forming a cavity under said dome, said cavity being adapted to completely surround and include the leaking device, and to accumulate hydrocarbon fluid coming upwardly from the leaking device, said dome comprising at least one upper output opening adapted to extract the hydrocarbon fluid for recovering, and wherein the containment system is characterised in that the dome further comprises an over pressure valve to extract fluid out from the cavity to the environment if a pressure difference between the cavity and the environment exceeds a predetermined pressure limit.
