Containment system and a method for using said containment system

摘要

A containment system for recovering hydrocarbon fluid from a leaking device comprises a dome situated above the leaking device and forming a cavity for accumulating hydrocarbon fluid from the leaking device, and an injection system that inputs an injection fluid into the cavity. The injection system comprises a plurality of first injectors near the domes inner surface.

1. A containment system for recovering a 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 comprises:
a dome situated above the leaking device and surrounding said leaking device, and forming a cavity under said dome, said cavity being adapted for accumulating 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 an injection system that inputs an injection fluid into the cavity for preventing or remediating hydrates inside said cavity, and wherein said injection system comprises inside the cavity a plurality of first injectors, each one of said plurality of first injectors is at a first distance from a dome inner surface lower than a first limit adapted to spray a quantity of the injection fluid onto said dome inner surface and a plurality of second injectors, each one of said plurality of second injectors being of a different type compared to the first injectors and is at a second distance from the dome inner surface higher than a second limit, said second limit being higher than the first limit.
