Abstract
A hydraulically driven underwater pumping system may include a pumping module connected to a subsea base. The subsea base may be connected to: a subsea producing well via a production line that carries the fluid produced by the subsea producing well; and a production unit via a riser and a service line. The hydraulically driven underwater pumping system may receive working fluid from the production unit via the service line. Additionally, a pump, located in the pumping module, may be driven hydraulically by the working fluid and pump the fluid produced by the subsea producing well to the production unit. The hydraulically driven underwater pumping system may mix the working fluid, after being used to drive the pump, with the fluid produced by the subsea producing well that is pumped to the production unit.
