Our site managers and logistics specialists can expect challenging tasks, such as estimating the working speeds, calculating the transport routes – and coordinating everything with the weather conditions.
One single ship for the wind turbines, up to two ships for the foundation structures and up to three ships for connecting the cables travel from different ports and arrive at the construction site at different times. The site is further secured by a sea traffic management vessel.
The sea is a capricious project partner: It must not be too cold, otherwise the special cement used to join the foundation components will not set.
The transformer platform needs calm seas to reach its destination and set itself up. The wind turbines can only be installed at wind speeds of up to force 4–5.
For each construction phase, all components not only have to be transported to and installed at the site, which lies 32 km off the German coast, but the crews also need to be regularly replaced.
Even though it only takes around two hours for the crew transfer ships to sail to the construction site from our base port in Sassnitz, a heavy installation platform can take up to 12 hours to get there. As such, it is essential to think of everything – because every delay can cost a six-figure sum each day.
