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.
Claims9
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, and wherein the containment system comprises:
- a pipe having a lower end positioned above and substantially near the leaking, device and an upper end positioned substantially near the sea surface, said pipe conveying an input fluid that is a mix of components, said components comprising at least water, oil, gas, and hydrate,
- a treatment facility fed with the input fluid from the pipe and separating the components of the input fluid, and
- wherein the containment system is characterized in that:
- the pipe has a diameter adapted to convey the hydrate from the lower end to the upper end, and
- the treatment facility comprises a tank connected to the pipe for receiving the input fluid, adapted for dissociation of hydrate component and adapted for providing an output fluid having a concentration in oil higher than the concentration in oil of the input fluid, and the treatment facility comprises a heater device inside the tank for heating the input fluid.
