Alert 09 – 28 Near Miss – Damaged Man-Riding Winch


The drilling crew was running 18 5/8”casing. While preparing for a personnel hoisting operation a floorman was checking out the man-riding winch when he noticed that it was not working properly. A test was conducted by the mechanic who discovered that the winch drum did not rotate with the control lever in the lower personnel position. The man-riding winch was immediately removed from the rig floor to repair and replace damaged mechanical parts.
