MARINE HEAVY LIFT 11TH
PROJECT – NORDSEE ONE
MAJOR
Buss Offshore Solutions is handling the port logistics of the Nordsee One windfarm at its own Orange Blue Terminal in Eemshaven. The halfway point has already been reached
Creating an offshore windfarm is challenging. A major project of this nature, which usually involves different service providers in its realisation, requires a precise planning schedule. Work on the windfarm has to go hand in hand since each delay may result in considerable additional costs.
BEHIND THE SCENES Whereas wind turbine manufacturers such as Senvion or Siemens are familiar and also operators such as EnBW or E.ON, there are a handful of service providers that contribute behind the scenes, one of which is Buss Offshore Solutions. Buss Offshore Solutions advises international customers in the offshore, onshore and oil & gas logistics industries and develops port logistic solutions for projects such as wind turbines or pipelines.
HEADQUARTERS Its headquarters are in Hamburg, where project planning and project management take place. Operational implementation takes place at either one of the three terminals in Eemshaven (The Netherlands), in Sassnitz on Rügen (Germany) or Stade in Hamburg (Germany). In addition, operational planning and implementation is also carried out at external terminals.
In addition to projects such as Global Tech I, Gemini or Veja Mate, Buss Offshore Solutions is currently managing its eleventh major project: Nordsee One. To consolidate, store and pre-assemble the components of the windfarm, Senvion has chosen the Dutch Buss Orange Blue Terminal as the base port. Together with Buss Offshore Solutions, it is taking care of all services upstream of and at the terminal.
54 WIND TURBINES In total, Nordsee One comprises 54 wind turbines. The offshore wind logistics specialist is temporarily storing the 378 individual components at the terminal, pre-assembling them and moving them one after the other to the loadout at the quayside. Each of the 27 loadouts comprises two nacelles, two towers and two complete rotors, which must be pre-assembled and delivered.
“The biggest challenge is preparing the components just in time at the quayside so that the installation vessel can load them in the time scale assigned for this. The time that the installation

vessel requires to ship and install the components at the construction site and be ready again at the terminal, is clearly defined,” explains Martin Schulz, Head of the Buss Offshore Solutions division. The 65-metre high towers compromise two sections each, which are installed at

the terminal beforehand using large cranes and must be installed on top of each other on a base specially constructed for this project. Buss uses its ultra-modern self-propelled modular transporter (SPMT) for processing components such as the pre-assembled rotors with a diameter of 126 metres. In addition to the size of the components, external factors such as the weather conditions or the wind window require a high level of flexibility from all those involved. The project is expected to be completed in autumn 2017. Everything is currently going to plan - in June, half of the loadouts had already been completed.
