Alert 18-01 Sheared Wireline Tool Results in Dropped Object
WHAT HAPPENED:
While making up a wireline tool assembly, the rig heaved while the wireline string was being lowered by a rig floor winch. As the rig heaved, a needle valve bleed off manifold on the Coil Tubing Lift Frame (CTLF) made contact with the tool string lifting bridle. Upon contact with the bridle, the needle valve bleed off manifold sheared off at the threaded coupling and fell directly to the rig floor. The needle valve bleed off manifold weighed 7lb. and fell 30ft. No injury to personnel resulted from this incident.
