The HHLA Container Terminal Altenwerder (CTA) with the 1,400 meter long Ballinkai in the Altenwerder district of Hamburg has been one of the world's most modern container terminals since it opened in 2002. It belongs to Hamburger Hafen und Logistik AG (HHLA) (74.9%) and Hapag-Lloyd AG (25.1%) and is located on the Köhlbrand, a side arm of the Elbe, between the Kattwyk Bridge and the Köhlbrand Bridge. The CTA also has its own container terminal for combined transport, the Kombi-Transeuropa Terminal Hamburg (KTH). Block trains are handled by four gantry cranes with slewing gear trolleys on nine parallel tracks, each 700 meters long. A freight transport center has been built right next to it, which can also use the station. The terminal covers an area of 1.1 million m² and is designed to handle around 3 million TEU annually in the final stage of construction. The capacity is currently 2.4 million TEU. Up to four large container ships, including post-panamax ships, can be loaded and unloaded at the same time on the 1400 m long quay wall to the east of the CTA. The draft at the berths is 16.7 m, the quay wall is 7.5 m above sea level. NHN. A total of 12 million m³ of sand was piled up, resulting in a height difference of 24 m between the quay edge and the bottom of the Elbe. The central container warehouse with a capacity of 30,000 TEU takes up the largest part of the handling area, of which 2040 have connections for refrigerated containers (“reefer”). The warehouse is served by 26 pairs of cranes and 86 Automated Guided Vehicles (AGVs). The western part of the CTA is made up of the transfer stations for trucks and the specially built station with seven tracks, which enables complete trains to be dispatched. Since 2016 work has been going on to refurbish and expand the facility by adding two tracks with an additional capacity of around 140,000 TEU to 930,000 TEU. In 2015, 769,000 TEU were handled here (2014: 785,000 TEU; 2013: 813,000 TEU. The special feature of the terminal is the almost fully automated process. The containers are practically only transported over the quay wall and the roadside with human control; all cranes and transport vehicles of the intermediate container storage are automatically controlled by a central computer.
