A resiliently deformable containment structure having an open bottom end and a raised center portion. A central hub, situated centrally in a textile containment sheet, is provided. A plurality of elongate inflatable beam members are arranged circumferentially around the central hub, each extending radially outwardly and in a downwardly-extending manner therefrom and each underlying or overlying the textile containment sheet to support, when inflated, the textile containment sheet in a downwardly-extending shape to form an enclosure having an open bottom end. Distal ends of the inflatable beam members are tethered to one or more anchor members situated below the open bottom end of the dome structure. The structure is suited for placement above and over a compromised sub-sea structure for collecting and recovering to surface fluids which may be leaking therefrom. A method for containing and recovering such fluids from a compromised sub-sea structure is further disclosed.

Disclosed is a subsea live hydrocarbon fluid retrieval system and method. The system and method include the ability to depressurize the fluid while enacting controlled venting of the gas entrained in the fluid during a controlled ascent to the surface from the seabed. The system and method do not require ancillary equipment at surface for management of gas or pressure. The fluid arrives at surface with minimal gas and pressure.

A subsea blooming system and method of deploying a subsea blooming system includes a first buoyant module, a first line extending downwardly from the first buoyant module, a first ballast module affixed adjacent an end of the first line, at least one boom translatably connected to the first line, and a variable buoyant module cooperative with the boom. The first buoyant module is positively and non-variably buoyant. The first ballast module is negatively and non-variably buoyant. The boom includes a plurality of booms that are connected in end-to-end relationship in a desired array.

A membrane system isolates environment volume, contains hazards, enables detoxification, hazard removal, infrastructure restoration, and substance recovery. The flexible membrane system adjusts to advantageously shape its isolated volume and integrate existing infrastructure. Pollution and hazardous energy, including crude oil, toxic-gas, radioactive fallout, fire, and other hazards are isolated, while concurrently enabling access within the isolated volume. Pod encapsulated and readily deployed, the membrane system operates semi-autonomously, uses selective-filtering, specific gravity and substance differences to channel matter, mitigate hazards, protect the biosphere, preserve infrastructure and capture substances.

A portable subsea pollution dome with built-in gas separator that is capable of collecting oil, or oil and gas, from a leaking production well, venting the gas and storing the oil in built-in a storage tank.

An open water capture device comprising a structure, wherein the structure comprises an open bottom, a top, and one or more injection primary ports.

A containment unit for containing fluid leaks in an ambient liquid. The containment unit comprises a weighted base for being disposed around the fluid leak. The weighted base is positioned on top of one or more suction piles. Further, the containment unit comprises a curtain unit coupled to the weighted base. The curtain unit comprises a helical spring and facilitates containing the fluid leak in the ambient fluid. The containment unit further comprises a flotation unit coupled to the curtain unit. The containment unit also comprises thrust roller bearings to allow rotation of the curtain unit with respect to the weighted base and the flotation unit. The invention further discloses a containment system comprising multiple containment units as needed depending on the depth of ambient liquid and as a surface flotation unit comprising pumps, sensors and skimming units to allow for the fluid leaked to be transferred to a vessel.

A system for reducing buildup of solids in pipes used in underwater oil operations is disclosed. The system includes an annular pipe having an inner pipe wall and an outer pipe wall. The inner pipe wall defines an inner pipe configured to transport an oil. The outer pipe wall is displaced from the inner pipe wall. The outer pipe wall defines an outer pipe between the outer pipe wall and the inner pipe wall. The system includes an oxidizer delivery pipe having an oxidizer delivery outlet. The oxidizer delivery pipe is configured to supply an oxidizer to the outer pipe. The system further includes a fuel delivery pipe having a fuel delivery outlet. The fuel delivery pipe is configured to supply a fuel to the outer pipe. The oxidizer and the fuel release thermal energy in an exothermic reaction.
