A compensated motor barrier and pump lubrication fluids pressure regulation system for a subsea motor and pump module is disclosed, comprising a hydraulic fluid supply providing barrier fluid and lubrication fluid to the motor and pump module, a barrier fluid circuit (14, 15, 17) in which the hydraulic fluid is pre- tensioned towards the motor by a pressure applied from a first separating pressure compensator (19), a lubrication fluid circuit (21, 22, 24) in which the hydraulic fluid is pre-tensioned towards the pump by a pressure applied from a second separating pressure compensator (26). The second pressure compensator (26) is responsive to the pumped medium pressure at a suction or at a discharge side of the pump and applies the sum of that pressure and its inherent pre-tensioning pressure to the lubrication fluid circuit, and the first pressure compensator (19) is responsive to the pressure in the lubrication fluid circuit and applies the sum of that pressure and its inherent pre-tensioning pressure to the barrier fluid circuit.
