About MSC.1/Circ.1663
IMO MSC.1/Circ.1663 sets out international guidelines for the inspection, maintenance and testing of lifting appliances and winches installed on board ships. It defines how cranes, hoists and similar lifting devices must be examined at regular intervals by competent personnel to ensure safe operation and structural integrity. Where required, equipment must also be verified through proof load testing to confirm its safe working capability. The guideline establishes documentation, reporting and qualification standards that are now being adopted by classification societies and shipowners worldwide. Generally, the requirements also apply to lifting appliances with a safe working load below 1,000 kg, unless the flag administration grants specific exemptions.
