  • Subsea pumping system for pigging and hydrostatic testing operations
    Patent number: 10738913
    Abstract: A subsea pump and power system having a base unit positioned on the seabed to which is detachably mounted a power module tethered to a surface power source via a power umbilical. The base unit includes process pumps for carrying out subsea pumping operations and is lowered by a heavy lift cable into position on the seabed adjacent a hydrocarbon production facility prior to lowering of the power module on a tether. The power module includes a power unit which may include an electrical motor, or a hydraulic pump or both, one or more of which are driven by the umbilical extending from the surface. The tether supports the weight of the power module as it is lowered to the base unit and includes an electrical umbilical, a hydraulic umbilical or both.
