Once in the separator, a combination of changes in flow direction and reduced flow velocities allow the phases to separate. Gas with minimal liquid entrained flow out one line while oil with some water is pumped out another line. The pumping action also induces a flow through the oil/water separating section of the device. Water with little or no oil entrained flows by gravity out the bottom of the device.
- the open water capture device described herein may be designed to intercept a subsea oil and gas plume resulting from a well control incident or pipeline leak, separate the entrained oil and water from the gas plume, and send the oil and gas to the surface in separate lines for processing while leaving the water in the sea.
- the open water capture device may solve the problem of previous subsea containment dome designs in which a large volumes of sea water was entrained in the intercepted plume and brought to the surface by separating the water subsea and leaving it in the sea.
