Operating Requirements
As blowout happens, full-enclosed ram BOP is able to pack off an empty well or semi-enclosed ram is able to pack off the drilling tool with the same size as the ram. If long time of well close is necessary, the ram should be locked up manually and a nameplate should be provided for indication. The wheel is pulled to the station prior to turned back at 1/4~1/2circuit. Before opening rams, check whether the manual locking device is unlocked or not. Every time after opening rams, check whether rams are in the full open position or not in order to prevent pipes from damaging rams. Release pressure in the control manifold before opening or closing the door in order to prevent damage to O-Ring of the hinge. If the door is not in the full open position or its bolts not installed well, it is not allowed to open or close rams with hydraulic pressure
