Double Cycling

Double cycling is an operating technique that can be used to improve the utilization of quay cranes by converting empty crane moves into productive ones. Instead of using the current method, single cycling, where all relevant containers are unloaded before any are loaded, with double cycling, containers are loaded and unloaded simultaneously.

Financial Benefit Of Double Cycling

During the trial at the Port Of Rottardam , the adjusted average time for a single cycle was 1 minute and 45 seconds, and for a double cycle, 2 minutes and 50 seconds. Intercontinental freight rates are estimated at $.045 per TEU-km (Notteboom 2004). At this rate, each hour of idle vessel time costs the ship operator $10,000. The 40 second benefit of each double cycle is worth approximately $100. During typical operations, double cycling could provide approximately $350 per hour, saving about $15,000 on a large container vessel. With three cranes per vessel, this is comparable to the total crane operator’s wages for loading and unloading the vessel
