Seaport Concept: Functional Performance measure of Seaport

Hi
Kindly find the general functional KPI for Seaport.
Cargo & Vessel Dwell Time: The duration for which an entity (cargo or vessel) stays in the port for service is called dwell time of the entity. In the port parlance, the entities are mainly the vessel and cargo /containers. The time cargo / container remains in a terminal’s in-transit storage area while awaiting shipment by vessels in exports or evacuation by rail / road in imports adds on to costs and demurrages beyond stipulated time limits. Delays that prolong the dwell time may be caused on account of cargo as also on vessel account and entail financial costs.

Vessel related dwell time: From the time a vessel reports at anchorage to the time it is cast-off from the berth, is the Turn Round Time for the vessel. Dwell time of cargo/container and vessel broadly reflects the efficiency of the port. Thus measures adopted to reduce the dwell time have an influence on the efficiency of the port as also of the use of vessel hire time and laycan requirement.
Pre-Berthing Detention: This is the time taken by a ship from its arrival at the anchorage (reporting station) till it starts its movement to the working berth, i.e., operational berth. Pre berthing detention is a component of the total turnaround time and any increase in the pre-berthing detention thus correspondingly increasing what is termed as the Turn Round Time. Berthing shortages at ports or excess vessel traffic at ports typically result in pre-berthing detention. Continued berthing delays at any port can lead to eventual loss of vessel and cargo traffic.
Average Ship Turnaround Time: Total hours a vessels stay in port (buoy-to-buoy time) divided by the total number of vessels. Higher port efficiency can be measured by a shorter average ship turnaround time.
Non Working Time of Vessels At Berth: Non-working time is defined as sum of the “The Idle time from the time of berthing to start of work, idle time during ship operation and idle time taken from the time of completion of operations to sailing from berth together.

Turn Round Time (TRT): The Turn Round Time of a vessel refers “to the time the vessel reports at the anchorage to the time it sails out from the berth”.
Average Waiting Rate: Total hours vessels wait for a berth (buoy-to-berth time) divided by total time at berth.
Gross Berth Productivity: Number of container moves or tonnes of cargo (for break-bulk and bulk cargoes) divided by the vessels total time at berth measured from first to last line.
Berth Occupancy Rate: Total time of vessels at berth divided by total berth hours available.
Working Time Over Time at Berth: Total time of vessels serviced at berth divided by total hours at berth. Reasons for non-working time may include labour agreements and work rules, rain, strikes, equipment failure, port operating schedules and holidays.
Ship Productivity Indicator: This refers to total number of moves (for containers) or tonnes handled (for break bulk and bulk cargoes) divided by total hours in port.
Tonnes per Gang Hour: Total tonnage handled divided by total number of gang hours worked
TEUs Per Crane Hour: Total number of TEUs handled divided by total number of crane-hours worked.
Tonnes per Ship-day: Total tonnage of cargo handled divided by total number of vessels in port.
