  • Patent number: 8978771
    Abstract: Systems and methods include using a subsea machine for separating a mixture received from a seabed well. The subsea machine includes: a chamber configured to receive and separate by gravity the mixture received from the seabed well. The chamber includes: a housing configured to contain the mixture received from the undersea well during separation, and a piston provided inside the housing and separating the housing into a top section and a bottom section. The piston is configured to move in a first direction along an axis to create more space in the top section for receiving the mixture from the seabed well and to move in a second opposite direction along the axis for removing the mixture from the chamber after separation has occurred.
