Abstract (en)
[origin: US2011274496A1] The present invention pertains to a rapidly deployable, low cost, submersible leak remediation device for capturing lighter specific gravity materials leaking from a submerged leak location in a heavier specific gravity fluid. The device features: an anchor unit; a collection shroud capable of being anchored in place in proximity over the submerged leak location to permit the materials to flow upward into the collection shroud interior space, through a riser conduit and into a floating surface collection hub in fluid communication with the collection shroud. Another embodiment of the present invention utilizes a shroud system that can be employed to capture materials leaking from a side rupture of a substantially vertical pipeline and direct such materials, through a conduit, to the surface collection hub. A method of deployment and use of these embodiments to collect such leaking materials from subsea locations is also disclosed.
