Crane moves per hour as a terminal efficiency metric poses methodological and data collection challenges.

• “Cranes moves” may include handling hatch covers and restowing containers as well as movement of imports and exports
• “Hours” may include or exclude scheduled breaks, yard congestion delays, and other factors depending on data collection practice
• Crane moves per hour can be affected by vessel stowage and adjacent bay constraints, particularly with large alliance vessels.
• The use of additional cranes to shorten vessel dwell time may compromise crane productivity
• Agreements between carriers and terminals sometimes specify the number of cranes to be provided per vessel call
