ABSTRACT:
A submergible pump assembly is installed in an underwater wellhead and rendered operable without the use of divers. A hose is guided down a cable extending upwardly from the wellhead and is inserted in a wellhead entry horn. The pump assembly is then lowered through the hose and into an upright tube in the wellhead. The pump assembly is locked in position in the tube and is connected to electrical power lines by remotely controlled hydraulic actuators in a sealed housing adjacent to the tube, the locking of the pump assembly also sealing the assembly in the tube concurrently. After the pump assembly has been installed, the hose and a running and retrieving tool in the hose are removed from the wellhead.
