Three New Studies
• Port Capacity Study, sponsored by the USACE Institute of Water Resources (IWR) CDM as prime contractor
• Port Productivity Study, sponsored by the Container Handling Cooperative Program (CHCP)
• Truck Drayage Practices, sponsored by the National Cooperative Freight Research Program, Transportation Research Board, National Academy of Sciences, Project 14
• All three studies nearing completion

Port Capacity and Productivity
IWR Port Capacity Study - Key Questions• What is East and Gulf Coast port capacity?• What constrains capacity?• Can they handle new Panama Canal vessels and
business?
CHCP Port Productivity Study - Key questions • Are we using the right productivity measures?• Where do we get the data?• How do we approach benchmarking?• How do we encourage productivity improvements?

CY Metrics
Cheap land at U.S. ports leads to:• Lower TEU/acre • Dedicated carrier terminals • On-terminal chassis pools• On-dock rail transfer• Wheeled operations• Fewer moves per box• Lower terminal operating costs
Key Metrics• TEU per CY acre• Slots per acre (density) and TEU/slot (turns)• Utilization – annual TEU vs. CY capacity

Crane Metrics
The primary task is turning the vessel• Crane utilization and productivity can be measured in
TEU and vessels worked• Crane efficiency would be measured in moves/hour, but
data are seldom available
There is a critical tradeoff• Annual crane output is higher if fewer cranes work the
vessels
BUT• Vessel turns are faster and more reliable with more
cranes

Berth & Vessel Metrics
Berth utilization can be measured in multiple ways• Vessel calls and TEU per berth• TEU as percentage of maximum vessel capacity• TEU as percentage of current vessel capacity
Vessel utilization is also a factor• Average vessel size compared to maximum possible for berth
and channel depth• Average TEU per vessel as % of vessel capacity

East & Gulf Coast Capacity
Most East and Gulf ports have CY, crane, and berth capacity to handle additional near-term Panama Canal business
• As larger vessels are phased in over time, most East and Gulf Coast ports will have to add cranes
• NYNJ and Norfolk can handle large vessel drafts today, although NYNJ has a long-term air draft problem
• Baltimore, Philadelphia, Charleston, and Savannah have dredging programs in progress or proposed
• Rising volumes will eventually require additions to road and rail infrastructure
![Page 20: Port Drayage, Productivity, and Capacity: Results of Three New Studies March 1, 2010 PRELIMINARY ^](https://reader030.vdocument.in/reader030/viewer/2022032723/56649d0b5503460f949deb4f/html5/thumbnails/20.jpg)
20Tio g a
US Port Productivity
Terminals attempt to balance the five dimensions of capacity• Berths long and deep enough for the biggest expected vessel
• Enough berths and cranes to avoid vessel delay
• Enough CY acreage and density to avoid congestion
• Enough hours to turn the vessel
US Ports are underutilized, not inefficient• Cheap land has led to large, individual terminals instead of
small multi-user terminals
• Most ports have substantial excess capacity
• Lower density holds down costs
Better productivity metrics are possible• “Sometimes” data such as CY acres, TEU slots, and crane
hours can yield better measures
![Page 21: Port Drayage, Productivity, and Capacity: Results of Three New Studies March 1, 2010 PRELIMINARY ^](https://reader030.vdocument.in/reader030/viewer/2022032723/56649d0b5503460f949deb4f/html5/thumbnails/21.jpg)

NCFRP-14 Port Drayage Project
Key questions• Where are the bottlenecks and delays?• What are the causes?• What are the solutions?
Answers• The terminal drayage bottlenecks are the gate,
CY, and chassis pool• The causes are congestion and exceptions• The solutions include terminal improvements,
operating practices, and exception reductions

Chassis Transactions and Pools
Chassis transactions add drayage time and delays at stacked terminals
• Two sources of delay – finding the chassis, and waiting for the box
• Two source of exceptions – chassis problems and transfer problems
• Moving pools off-site to save space adds drayage trips and time
• Chassis interchange adds time to gate transactions
In the near term, neutral pools expedite chassis searches and reduce equipment problemsIn the long run, trucker or third-party chassis supply should reduce terminal time and exceptions

Drayage Solutions
Reducing Bottlenecks• Keep gates open during lunch • Chassis pool – Saves time in stacked terminals• “Automated” gates – OCR, RFID, saves gate time • Two-stage gates – Gets exceptions out of line• Appointment system – May save time, depends on
implementation
Reducing Exceptions – The 5% “tail”• Talk – regular trucker/terminal/port/customer meetings• Manage booking, dispatch, and system communications • Choose experienced trucker and efficient ocean carrier

Terminal & Drayage Tradeoffs
Higher terminal density has costs…• More cranes to handle larger ships• More berth and CY congestion on vessel days• Higher terminal operating costs due to more moves per box,
more labor, and more capital• Higher drayage costs due to more time and moves in terminals • Greater impacts on roads and rails
The transition has to be managed carefully…• A long-term solution to on-terminal chassis supply• Terminal operations that move both vessels and trucks• Gates that expedite clean transactions and separate problems• Systems to cope with rising complexity of terminals and
transactions
