Lecture 9: Port Production and Efficiency Flashcards
Q: What are the 6 key technologies that enhance terminal productivity?
- Tandem QC
- Triple Lift QC
- Semi-Automated QC
- Automated RTG
- Automated Gatehouse
- Fully Automated Terminal
What are the 4 KPIs determining Terminal Handling Capacity level?
- Quayside
- Landside
- Equipment
- Gatehouse
What are the main operational KPIs at port terminal?
- Port Rate
Total no of containers handled on a vessel during its port stay
Total no of containers handled exclude restow, hatch cover movements, uncontainerised cargoes
Units: mph (Movements per hour)
Eqn: Gross Port Rate= No of containers handled on Vessel / Port Stay= mph - QC Rate
Total no of containers handled on a vessel with a total operating time operated by a no of QCs
Cause (QC rate increase)–> Effect (Port Rate increases)
Summation of no of containers divided by summation of QC operating time
Units: mph - RTG rate
Rate to reflect the productivity of RTG
Sum of RTG movements / Sum of RTG operation time
Units: mph - Prime mover Turnaround Time
Average time required for an external prime mover to complete a round trip for container collection or delivery upon entering or leaving the container terminal
Units: Minutes per prime mover
(Reasonably fast turnaround time is around 45 mins - 1 hour)
What technologies are found in an Automated Gatehouse?
Laser scanning for container damage and Optical Character Recognition for capturing container numbers and license plates.
How does a Semi-Automated QC function and where is it adopted?
Double Trolley- main trolley land container on platform
Automatic Trolley will move container to AGV near SY
Adopted in Hanburg’s Altenwerder container terminal
What is a Tandem QC and its productivity rate?
A crane that handles 2×40’ or 4×20’ containers side by side. QC Rate: ~45 mph.
What is a Triple Lift QC and where is it used?
Has 3 spreaders to lift 3×40’ or 6×20’ containers simultaneously.
Used at Shenzhen’s Chiwan Container Terminal.
What does Prime Mover Turnaround Time measure and what’s considered efficient?
- Average time required for an external prime mover to complete a round trip for container collection or delivery upon entering or leaving the container terminal
- Units: Minutes per prime mover
(Reasonably fast turnaround time is around 45 mins - 1 hour)
What is Port Rate and how is it calculated?
Total no of containers handled on a vessel during its port stay
(Total no of containers handled exclude restow, hatch cover movements, uncontainerised cargoes)
Units: mph (Movements per hour)
Eqn: Gross Port Rate= No of containers handled on Vessel / Port Stay= mph
What is QC Rate and how does it affect Port Rate?
QC Rate = Sum of containers handled / Total QC operating time. Unit: mph.
What is RTG Rate and how is it calculated?
A: RTG Rate = RTG movements / RTG operating time. Unit: mph. Measures RTG productivity.
Why is equipment capacity important for handling operations?
More concerns on landside container handling equipment
Support quayside and stacking yard operations
Support restow move required in digging out the designated container
*Should design to have sufficient equipment to support operations during peak hour of the day.
What determines the number of traffic lanes at a gatehouse?
The ability to meet peak hour demand on a peak day — both at in-gate and out-gate.
What does Quayside capacity refer to in terminal operations?
Maximum capacity of a terminal to handle its vessels at quayside (QC/Berth utilisation
What is Landside capacity and what does it depend on?
A: Max stacking yard capacity to store containers handled through both quayside and gate traffic (stacking demand).
What is a Fully Automated Terminal and give one example?
A: Terminal using full automation across QCs, RTGs, and gatehouse. Example: Caofeidian Terminal (conceptual design).
