Abstract
A subsea pump system is adapted to close a hydraulic ram of a blowout preventer. The subsea pump system has at least a first pump and a second pump configured to pump drive fluid from a source to the hydraulic ram. The system has a controller configured to automatically select at least one of the first and second pumps for pumping the drive fluid wherein at least the first pump is selected at a lower fluid pressure range and at least the second pump is selected at a higher fluid pressure range. A method of operating a pump system and an intervention skid for a pump system are also described.
