2020 2nd alert HiPo#27a (Drops) uncontrolled descent of traveling block
Operation was just start POOH tubing completion with ESP cable. On joint no-3 (at string weight of about 10 kdaN) the driller picked up about 3 m and stopped to cut the cable band. After cutting, he further attempted to pull out, but the travelling block started coming down. He tried to control the free fall by applying auxiliary brake. The block continued to descend, the elevator pulled down the hydraulic tong, and elevator came to rest on the hydraulic tong. Finally, the block stopped when the ACS got activated.
Always watch out for fatigue during Summer and Ramadhan. Always ensure to take enough rest before joining the task. Always ensure to exercise your Empowerment to Stop if you feel an y sign of fatigue. Always ensure Driller and AD to practice a drill on how to react in such situations (apply ESD).
