2025 Second Alert HiPo#23A_Make up BHA _Drop
after picking up the 6.125” motor, the crew hand-tightened the bit and placed it in the bit breaker. The Acting Driller then slacked off the BX elevator to begin making up the connection using manual tongs. At this point, the BX elevator unexpectedly opened, causing the motor assembly to fall from the Rig floor, striking the pipe-cat and rested on it. The Acting Driller immediately instructed the crew to move out from Red Zone. Fortunately, no injuries occurred at the time of the incident and pipe-cat “No-Go Zone“ was respected.
Maintenance team to increase inspection frequency for checking the condition/function of the pressure reducing valve. Maintenance team to Review Maintenance Craft Procedure (MCP) to address the function of the pressure reducing valve and align with OEM recommendation. Rig manager to ensure implementing the updated SOP of P/U BHA to check the function of BX elevator. Chief Electrician to ensure date/time on Amphion software time is synchronized with actual date/time before spud the well
The TBT was conduct and SOP was followed, and roles were clearly understood. The Pipe-cat area and “No-Go” zone management fully respected, hard barrier were installed around the Pipe-cat. Good response and quick evacuation by crew from Red-Zone. The BX elevator malfunctioned, as it unexpectedly opened (without command from driller) and the Amphion screen was still showing ‘close’ status, despite the BX was fully inspected on 20th May 2025 and pre-use function test has been performed. The valve was stuck and not responding to reduce the pressure due to corrosion. Amphion date/time wasn't synchronized with actual time.
