Abstract: 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 system comprises a lower closing assembly for closing a lower opening during descent of the system to the seafloor.

Abstract: A containment system for recovering hydrocarbon fluid from a leaking device comprising a wall extending from a base level to a first level for surrounding the leaking device, and a dome situated above the wall and forming a cavity for accumulating hydrocarbon fluid. The dome comprises an upper output opening for extracting the hydrocarbon fluid. The containment system further comprises a lower output opening extending up to a dome level. The wall and the dome are independent members so as the wall can be landed on the seafloor before the dome is installed.

Abstract: 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. The containment system comprises a sensor for measuring an interface level of a fluid interface between hydrocarbon fluid and any other fluid inside the dome, and an output valve connected to the upper output opening for outputting hydrocarbon fluid, and controlled on the basis of the interface level measured by the sensor.

Abstract: 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 a first dome and a second dome connected to the first dome. The second volume of the second dome is smaller than the first volume of the first dome.

Abstract: A containment system for recovering hydrocarbon fluid from a leaking device situated at a deep seafloor comprising a pipe for conveying an input fluid that is a mix of water, oil, gas, and hydrate, and a treatment facility fed with the input fluid from the pipe and separating the components of the input fluid. The treatment facility comprises a tank for dissociation of hydrate component and extraction of the oil component. The treatment facility comprises a heater device inside the tank.

Abstract: 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.

Abstract: A wash separator comprises a vessel containing a first fluid and a second fluid whereby the second fluid has a different density from the first fluid. The first fluid (3) is immiscible with the second fluid and the first and second fluids are separated from each other by an interface. A feed stream comprising a dispersion of the first and second fluid wherein the second fluid forms a disperse phase in the form of droplets is distributed within the first fluid in the vessel forming a continuous phase. A distribution element is provided in the vessel to distribute the feed stream into the second fluid. The feed stream after having been discharged from ,the distribution element has a retention time of at most 15 minutes in the feed second fluid in the vessel.

Abstract: The invention relates to a process for the purification of crude and apparatus for its implementation. This process comprises a separation into gas and degassed emulsion and separation of the degassed emulsion into water and oil. The invention also relates to a process of separating a hydrocarbon emulsion and apparatus for implementing this. This process comprises washing of the emulsion at an oil/water interface.
