Where containers meet world records
The Short Sea Terminal in Bremerhaven is being extended
Bremerhaven is booming: this where the real leviathans can tie up.
Not only containers are stacking up at the
Bremerhaven Container Terminal (CT), but also
records. With a storage area of two million
square metres, it has been entered in the
Guinness Book of Records as the world's largest
connected container terminal. It was here in
September 2006 at Bremerhaven that the
world's largest container ship, the "Emma
Maersk", moored up at the longest riverside
mooring in the world. After the planned extension,
the storage area will even amount to three million
square metres, and the extension of the CT
Bremerhaven is Germany's largest maritime
building site. The Bremen port operators are not
just investing in Germany's largest port project -
the CT4 riverside quay. There are building
projects underway throughout the harbour. In
building the Short Sea Terminal, bremenports is
continuing to drive the modernisation of its quay
facilities and inner harbour areas forwards. In the
south west area of the turning basin for the
international port, bremenports is preparing a
short sea mooring for container handling and for
this purpose, a 210 metre long quay is being
driven. Apart from the extension of the storage
spaces, deepening of the harbour basin by
approx. 5.50 metres is also planned, in which
ThyssenKrupp GfT Bautechnik specialists were
also involved.
And this was with success, since the customer
bremenports was able to save 15 percent on
material at the short sea terminal, while also
managing to gain a substantial time advantage
in the processing of the project, thanks to the
innovative suggestions and ideas provided by the
ThyssenKrupp team.
The tender was for PSp 900 and PSp 800 beam
piles, in combination with the PZi 612 intermediate
pile. The alternative worked out by ThyssenKrupp
GfT Bautechnik with the newly-developed PZi 675
intermediate pile and PSp 800 beam pile in special
steel provided the decisive benefit, enabling less
pile driving elements to be driven into the ground
thanks to the wider system measurements, thus
saving time and materials. The equivalence
documentation required, such as stress detection
for the sheet pile interlocks, was supervised by the
technical offices at ThyssenKrupp Bautechnik and
released to the full satisfaction of the testing
engineers.
High ramming performance
Apart from being the system provider and supplying
the sheet piling, ThyssenKrupp Bautechnik also
provided the driving technology and equipment. The
most recent Mueller vibration technology was used,
which could provide rapid, simple and precise driving
of the beam piles (up to 29 metres in length) and
intermediate piles (up to 23 metres long). Because
the well-trained site team had such a high ramming
output with the machines supplied by ThyssenKrupp
Bautechnik, backup supplies had to be delivered by
three ships rather than just one, as originally
intended. The beam piles measuring up to 29 metres
in length were delivered by ThyssenKrupp on ships
