2020 2nd alert HiPo#36 (Drops) TDS body has caught and opened this spelter causing the tong to drop
Operation was RIH tubing with Down Hole Gauge cable. On joint no-4 after installing first & second cable bands, Asst. driller started to lower the string meanwhile Floor man was reaching out to lower the power tong simultaneously. Suddenly the Hydraulic tong fell on slips guard. The Hyd. Tong hang-off line had a short extension sling having open spelter on top connected to the tong hang-off line & hard eye on bottom connected to hyd. tong hanging cylinder. The Top Drive body caught the spelter, knocked out the spelter pin causing the tong to drop & land on Cavin slips guard. The hyd tong is NOV Gill 600 closed-end around the tubing. No Injury to anyone.
Always ensure TDS/Block path is always free from lines or obstruction. Always pull and secure the power tong hang-off line away from TDS. Always apply red-zone management: don’t attempt to lower the power tong while lowering string. Always stop when there is an anticipated risk and communicate to the supervisor.
