Current focus: rolltrailer operation
Roll-on/Roll-off operationsType of goods handled:• cars, trucks, semi-trailers, farming
machinery etc.• machinery, boats etc. (on rolltrailers)
Project background
Average inventory at the RoRo-terminal of Bremerhaven:
• 500-1000 roll-trailers (owned by shipping companies)
• 15 terminal tractors with goosenecks for maneuvering rolltrailers (“Tugmasters”, BLG-owned)
• Throughput: 60.000 rolltrailers per year
Restrictions in physical growth (financial and topographic) call for a process oriented approach

Automatic entry into database
Select RFID tag
Input data terminal: Link transponder 102to rolltrailer 57
Attach transponder on load carrier
Operating mode – storing the load carrier
What´s myposition?
RFID reader: Who´s there?
1 Permanently checking position and tag ID (minute cycle); logging data
Satellit (GPS)
Your position is B2
It´s me, tag 102
2 Sensor reports uncoupling processData terminal: tag 102 is left on B2
3 Sending tag ID and location dataDatabase: tag 102 → rolltrailer 57→position update: rolltrailer 57 now on B2

Hierarchical AutoID – and localization system
Automatic identification
•identification of individual rolltrailers•difficult environment (metal, corrosive air, rough handling ...)
Navigation
•continuous localization•sufficient accuracy•high availability
Communication
•interchange of real-time-data on rolltrailer positions and status
Economic design
•large number of rolltrailers equipped with low prize RFID-tags (recycled in close-loop-application)•small quantity of terminal tractors equipped with processing/RFID-reader/navigation/communication modules
Aspects of the solution
Verification and implementation. First Step: Demonstrator

Identifying the optimal position for a RFID tag
Set up:20 passive RFID tags have been attached to 7 different rolltrailers2 different types of tags were used: „Deister“ and „Confidex“
Test:How do RFID tags „survive“ the mechanical stress and weather conditions (temperature varies from – 30 °C to +35 °C/ -22 °F to 95°F)?How endure transponders when transported onboard a vessel and handled by other seaport terminals for extended periods?Are the tags still operational after 1 week, 1 month, ½ year and over one year?
Results:No RFID tag has been destroyed or damaged
=> all tags are still intact after 20 months!

Conclusion and outlook
Central objective of the project
Developing a system that captures position, time and status data of rolltrailers with the objective to improve rolltrailer management in RoRo-terminals and reduce use of costly resources.
Project development
Outlook
Once fully developed and tested the system can easily be extended to shipping companies and co-operating seaports – thus expanding the closed-loop-application to an open-loop-solution and thus rendering manual trailer identification at entry unnecessary!
