2 Introduction Important parameters for container terminal capacity technical features operation time (technical) dwell time handling system vessel type capacity of ship to shore cranes terminal stacking capacity area vessel size annual working time stacking height quay capacity number of gantries vessel length quay length / berths Source: Burkhard Lemper: Efficiency of the seaport container throughput market of the north range 2

3 Introduction Capacity planning for container terminals Targets Where is the bottleneck of the terminal? Quay or stacking area? With how much throughput does a terminal cope with the existing capacity? Quay evaluation Is there sufficient quay length to operate a given container volume? What is the utilization of the quay? What is the number of quay cranes required to handle the container volume? Area evaluation Is there a sufficient number of stacking slots? What is the utilization of the stacking area? 3

4 Introduction Example of application 4

5 Introduction Example of application Quay length: yearly throughput: share of transhipment: 60% share of 40 ct.: 60% storage capacity: 1,500 meters 1,500,000 TEU 33,268 TEU peak month: October (140%) vessel types: jumbo and medium (main vessels), feeder vessels 5

6 Input Input of general terminal data yearly throughput monthly peaks container mix 6

7 Input Information about the container stacking area max. area utilisation container dwell time available slots to store containers of different types Area utilisation before simulation starts calculation or manual input 7

8 Input Definition of vessel types details of quay usage details of vessel types and vessel sub-types details of throughput distribution measurements details of quay performance 8

9 Input Throughput flow 9

10 Input Throughput distribution total throughput flow share of main vessel throughput 10

11 Input Weekly vessel distribution Development of an average weekly vessel schedule 11

12 Input Quay editor definition of landside and quay side terminal boundaries drawing of any desired quay with the quay editor Usable quay length 12

13 Input Input of vessel schedules vessel type arrival time deviations throughput QC performance container mix input of single vessels 13

14 Simulation Simulation Simulation period: 1 year Preliminary time: 2 weeks (for pre-occupancy of quay and stacks) Simulation - single run for configuration check - several runs for evaluation of the checked configuration Saving of simulation results - data of each single run are saved - data of all runs are averaged and saved 14

15 Animation Animation of a simulation run 3D animation of the quay Animation of the area utilisation On-line animation during a simulation run Supplementary animation for fault analyses The last simulation run is recorded as a film which can be turned back and forward. Adaptation of the animation speed according to the requirements Zoom and sight onto the terminal from various perspectives 15

16 Animation Animation of a simulation run 16

17 Statistics Evaluation of simulation results Quay evaluation quay utilisation - maximum and average no. of used quay cranes - maximum and average Vessel evaluation berthing time and waiting time - maximum and average (separated in vessel types) rejected vessels - waiting time over maximum crane performance - minimum, maximum and average Area evaluation Evaluation of the area utilisation regarding to capacity overrun as well as maximum utilisation overrun 17

18 Statistics Evaluation of a single run - overview survey of simulation results / seaside Survey of the maximum number of cranes used for each month and simulation run 18

19 Statistics Total evaluation evaluation of the vessel types Feeder, Medium, Jumbo evaluation of the crane performance evaluation of the area and quay utilisation weekly vessel distribution 19

20 Statistics Vessel distribution monthly arrivals of Feeder, Medium and Jumbo vessels 20
