Burchardkai Container Terminal receives LPR global positioning system from Symeo
Major order after successful tests in largest German trans-shipment centre for containers
The Burchardkai Container Terminal owned by Hamburger Hafen und Logistik AG (HHLA) is the largest and oldest operation of its kind at the Port of Hamburg. Twentyseven shiptoshore cranes load and unload up to 5,000 ships each year and, within the next few years, the handling capacity is expected to double thanks to the modern anchorage for large ships and the automated block storage system.
Currently, around 110 van carriers and seven reach stackers are used to transport the containers around the terminal site, but the reach stackers work exclusively in the empty container area. The terminal operator is now planning to gradually equip the entire fleet of 6- to 12 mhigh vehicles with LPR systems in successive stages. This will help the operator to determine the exact position of the containers in the terminal.
Clear advantages of the new LPR system
Symeo's LPR solution uses wireless technology, which enables it to work independently of weather and visibility conditions and means that it is not affected by dirt or dust. The new LPR system enables the operator to determine the precise position of all vehicles in all areas of the terminal, especially in transfer areas to the new automatic storage system. In addition, with the new system, the height of the vehicles plays no role in system operation. The old laser system was only able to process vehicles of the same height. Also, the laser devices were getting older and were increasingly causing maintenance and repair costs. The Symeo LPR units have no moving parts, making them practically maintenancefree.
In addition, a problem with the existing DGPS receivers was that the signals from the GPS satellites were shadowed by tall nearby structures such as container stacks, ships and, in particular, shiptoshore cranes. For this reason, the system was unable to supply reliable GPS positioning data in the transfer area to the automatic storage area. Unlike the previous system, the Symeo system can securely cover even difficult areas, since the fixed transponders are suitably distributed across the entire terminal site.
Test proves LPR precise and reliable
The LPR system was subjected to extensive testing at the container yard , in the areas under the ship to shore cranes, the transfer area to the automatic storage area, the empty container storage area and on straddle carriers of different heights. The system met expectations in every area. The goal was to ensure that the system was highly reliable and able to track the position of containers with an accuracy of ±1 m. Over the course of the 14week test, the LRP system presented the operator with an availability of 99.2% and a positioning accuracy of up to ±20 cm.
Symeo plans to equip Burchardkai's entire fleet with LPR positioning systems in successive stages. The first ten straddle carriers are to be equipped with Symeo systems by June of this year. The system is to be installed on an additional 40 vehicles by the end of 2011. The positioning system will first be installed in the yard and the transfer area to the new automatic storage area. In the second phase of the installation, the positioning system is to be installed in the area under the shiptoshore cranes. The Symeo system is the only solution on the market that is capable of fulfilling the positioning requirements with the required reliability and accuracy.
Symeo develops and markets products and solutions enabling accurate and contactless position detection for vehicles, cranes, and objects, for distance measurement, as well as anticollision systems.
