Title: SUBSEA-POSITIONED LIQUID INJECTION PUMP AND BOOSTING SYSTEM FOR SUBSEA APPLICATIONS
Abstract:
A liquid injection system includes a motive fluid pump (20) that is adapted to supply a pressurized motive fluid (23, 25), at least one source (40) of a liquid (41), and at least one liquid injection pump (22) that is adapted to receive the liquid (41) from the at least one source (40) at a first pressure and to receive the pressurized motive fluid (23, 25) from the motive fluid pump (20), wherein receipt of the pressurized motive fluid (23, 25) into the at least one liquid injection pump (22) causes a discharge of the liquid (41P) from the at least one liquid injection pump (22) at a second pressure that is greater than the first pressure.
