Installation of the hydraulics
Ensure that the controls are designed in such a way that, after a hydraulic or
electric power black out, the actual situation of the valves doe not change. No
movement in any part of the tool is allowed after the power, either electric or
hydraulic or both, comes up again. The tool and load should always remain in a
safe state.
Ensure that there are valves installed which allow the tool to be insolated between
the hydraulic power rig lines and the tool. This is to prevent to have to shut down
all rig power lines or HPU’s in case of maintenance, emergency or otherwise.
NOTE: The elevator is filled with hydraulic oil at delivery. Ensure it is filled when
installing the elevator.
NOTE: Ensure to purge the air from the elevator before commencing work by
opening and closing the elevator 10 x.
