Objectives of the Course • the role and effect of warehouses in a supply chain
Outline • background • container ports • container terminals • goods and equipment • an example: HIT • decision problems
Terminology • TEU • twenty-foot equivalent unit, the standard unit to measure container throughput • a 40 ft container = 2 TEU
Venues for Container Transfer • container terminal • container yard • feeder ports and river ports • mid-streamoperations • public cargo working areas
Questions • How important is containerization? • What are the advantages of containerization? • pre-containerization (00:002:47) • bulk cargo • What are the functions of container terminals? • What facilities and equipment are required in container terminals?
Container Ports • world traffic • top 10 containers ports in 2011 • how to rank these ports: • Busan, Dubai, Guangzhou, Hong Kong, Ningbo, Qingdao, Rotterdam, Shanghai, Shenzhen, Singapore
Ranking ofContainerPorts • 2010 • 6 of the top 10 busiest container ports in China (units in TEU) • Shanghai (1st, 29.1 m), Hong Kong (3rd, 23.7 m), Shenzhen (4th, 22.5 m), Ningbo (6th, 13.1 m), Guangzhou (7th, 12.6 m), Qingdao (8th, 12 m) • Singapore (2nd, 28.4 m), Busan (5th, 14.2 m), Dubai(9th, 11.6 m), Rotterdam (10th, 11.4 m) • Tianjin (11th, 10.1), Kaohsiung (12th, 9.2 m) • 2011 • throughput of container ports in Taiwan • in decreasing importance: Kaohsiung (9.64 mill TEU), Keelung (1.75 mill TEU), Taichung (1.38 mill TEU)
A Container Terminal as a Warehouse • a special type of warehouse • very standardized goods for short term storage • some form of consolidation • flexible layout for the same type of containers • heavy equipment • highly information driven
A Container Terminal as a Warehouse • to “define” a container terminal • goods • equipment • information systems • layout • processes • problems
Types of Goods • containers • various types, of different size, weight, nature, port of destination, and port of origin, etc. • bulk goods • breaking down and building up at a Cargo Freight Station
Vessels • non-self sustained cellular (NSSC) • self sustained cellar (SSC) • self sustained non-cellular (SSNC) • car carrier/RoRo ships • ultimate container carrier (UCC) • lighter/barge

Equipment • crane • quay • job crane • rubber tyred gantry crane • front loader • rail-mounted gantry crane • bridge crane • other equipment • automatic guided vehicle • straddle carrier • tractors • reach stackers • scaffold platform • chassis
Hongkong International Terminals • relative location • a clearerpicture • terminals: 4, 6, 7, 9, and 50% of 8 East • areas • a total 92 hectares for terminals 4, 6, and 7 • 30 hectares for terminal 8 • 19 hectares for terminal 9 • > 5 km quay length, 14 ship berths, & 9 barge berths • 57 quay cranes, 8 rail-mounted jib cranes, 24 rail-mounted gantry cranes, 184 rubber-tyred gantry cranes , Hutchison Logistic Centre: 377,741 m2
Hongkong International Terminals • Example: HIT/COSCO HIT Terminals • operations • key facts, terminal layout, work flow, • virtual tour: guided tour and spots light work flow and information systems • throughput: 10.253 mill TEU in 126 ha (2010) • 1170 TEU/hour • 179,900 TEU/QC/year

Decision Problems in Container Terminals
Performance Indices • throughput • number per unit time • of container, of each type of container, of move • for terminal, cranes, gate house • utilization • cranes, space (block, stack, slot), berth occupancies • time in system • tractors, vessels, containers
berth allocation (allocating vessels to berths) QC allocation (allocating QCs to (bays of) vessels) storage space allocation (determining the numbers of I/B & O/B containers of each vessel in a block) location assignment (determining the exact locations of containers in blocks) RTGC deployment (deploying RTGCs in real time) Operations Decisions in a Container Terminal schedule and stowage plan of vessels IT deployment (deploying ITs in real time)

Advantages of Containerization • simplify packaging, loading, unloading, and custom checking of goods • reduce transportation times and costs • increase utilisation of vessels and ports
Advantages of Containerization • disadvantages of bulk goods in pre-container era • loading, unloading, and stacking operations for each carrier change • manually with low efficiency • high labor cost, 80% of total cost for bulk goods by 1960’s • long vessel porting time • good packaging consuming time and costs • damages • mixing up of goods • custom checking at each intermediate ports • more paperwork and high insurance charge
Time Taken for Containerization • not all goods can be containerized • the magnitude of changes • a totally new managing and controlling mechanism • new port design • new loading and unloading operations , replacement of • fork-finger quays replaced by long water front quays • small dollies and trolleys by huge shore and yard cranes • labourers by skilful equipment operators • Job reduction • huge investment in material handling equipment and human resources • new custom practice for eliminating individual consignments
Functions of Container Terminal • intermodal interface • temporary storage for containers • paperwork for containers • building up & breaking down of containers
Types of Container • ordinary dry container: most common
Types of Container • reefer container • temperature control • e.g., for frozen meat and diary products • ventilated container • holes for ventilation • for fruits and vegetables • insulated container • keeping heat from the cargoes
Types of Container • open top container • loaded and unloaded from top • for large-size, heave items • flat rack container • bottom part and two small sides • for heavy or odd-size items • platform container • a plain plate without sides • for extra large and/or weight
Types of Container • bulk container • for bulk goods • hatch covers on top for loading & unloading • free flowing bulk material container • for carrying powder, fluid, or gas • using pumps for loading and unloading
Types of Container • special purpose container, e.g., • dress hanger container • for clothes without folding • pen container • for animals • with net on its sides
