Global ocean-based trade has been increasing significantly. To keep pace with this growth, a new generation of large vessels has been introduced to maximize shipping productivity. The primary goal of container terminals is to accelerate vessel turnaround time through effective coordination of the main handling components. This study proposes an efficient strategy to handle containers by employing double-cycling to minimize the number of empty travel trips of yard trucks. To verify the efficiency of the proposed strategy, two simulation models were developed and implemented based on a real-life case study considering uncertainties in the work task duration. The integrated single-cycling model predicted productivity with an accuracy rate of over 97%, compared with the actual site productivity. When compared to the standard single-cycling model, the double-cycling model enhanced productivity and reduced vessel turnaround time by up to 62% and 38%, respectively, and achieved cost savings of up to 27%.
