WE DEVELOP FOR THE FUTURE
The continuous development of our technical know-how is one of our most important success factors. Novel manufacturing methods and construction systems are developed at an early stage to optimize construction sites.
Concrete platform and innovations
Together with the Danish company Per Aarsleff A/S we developed a concrete platform for the transition piece. The advantage: Lower maintenance intensity compared to a steel platform. The transition sections of the Horns Rev 2 and London Array offshore wind farms are already equipped with these concrete platforms. We have significant patents on installation methods and the use of innovative materials. With our know-how we develop innovative installation methods in order to be able to offer adequate solutions for future challenges.
direct drilling method
An innovative system was developed for the low-vibration production of combined sheet pile walls, whereby the supporting elements can be directly drilled in with locks. With the use of this system, the extensive preparatory work required for the low-noise and vibration-free installation of combined sheet piling in the drilling process can be saved. The elimination of pre-drilling, the associated drawing process of the casing and the filling process of the intermediate space also offers an immense advantage with regard to possible deformations in the existing structure.
A current focal point is sound insulation during installation work on pile foundations and sheet piling. A special soundproof chimney was developed for this purpose. Optimally developed pile systems are essential for the implementation of complex foundations. Within the framework of various construction projects, special constructions were developed for this purpose. These include, for example, patented processes for the production of buckling resistant vibration injection piles and high-load-bearing tubular pile foundations.
The use of underwater anchoring structures is one way of making optimum use of sheet piling structures. Especially in Scandinavia and the Baltic States these horizontal anchors are used. In order to avoid this extensive work, it was possible to design and apply for a patent for an underwater anchor to be manufactured without the use of divers.
In cooperation with an international consortium of energy suppliers, the horizontal load-bearing capacity of driven and vibrated foundation piles was investigated in two test projects in Cuxhaven and Rödby (Denmark). In addition to installing the foundation elements, including the world's most powerful vibrator, a horizontal test load device loaded with 20MN was designed.
