During pipeline offloading from a vessel to shore, winch base-plate welds failed, throwing the operator and seriously injuring his knee and lower leg. The flash examines replacement of a constant-tension winch, unresolved deflection and tension-measurement limitations, with corrective actions addressing change management, weld testing, procedures and load-cell calibration.
