Abstract:
A blowout preventer (BOP) lifting apparatus has a reinforced frame and a gate for securing a BOP stack. The frame has a central U-shaped recess for securing a collared portion of the BOP stack. The gate pivotally swings between a closed position on the frame and an open position for installation and removal of the lifting apparatus from the BOP stack. An actuator has a first end connected to a top surface of the frame and a second end connected to the gate for actuating the opening and closing of the gate to the frame. When the gate is in the closed position, three locking pins are inserted into three vertical pinning holes located on the frame, which are aligned with three pinning holes located on the gate. The apparatus may be lifted via cables or other lifting mechanisms attached via lifting eyelets located on each corner of the frame.
