high pressure hydraulic line underwater motor sp underwater engine connector integration

摘要

This is a method that includes placing an apparatus in an underwater wellbore, and hydraulically connecting the apparatus with an external hydraulic fluid source. The apparatus of this method includes a pump, a motor, a pressure intensifier, and a hydraulic fluid port. The motor is configured to drive the pump. The pressure intensifier is configured to maintain the hydraulic fluid pressure in the engine at a predetermined level. The hydraulic fluid port is configured to supply hydraulic fluid to the pressure intensifier by engaging with the external hydraulic fluid source when the apparatus is in a hydrocarbon producing wellbore. The appliance is sized to be lowered and retrieved through the column of the production pipe.
