ENGINE & TURBINE TECHNOLOGY


designed wind turbine cables, the internal rubber blocks must act as springs to compensate for these movements. The buoyancy of each module, with a diameter of two to three meters, requires individual calculations. Scaling or transferring specifications to other system projects is difficult, as they must account for each of the prevailing underwater conditions and the various technical requirements. Consequently, system-engineering companies design and produce their own modules for each project. This requires great effort in terms of development, production and underwater installation, which is why the components are required to have a long service life.


LIFE SPAN OF WIND TURBINES While lifespans of up to 25 years are expected in the oil and gas industry, up to 37 years of reliable buoyancy without failures in the field are called for in the floating offshore wind sector. And this is where the materials experts at Freudenberg Sealing Technologies come into play. ●


Polyurethane buoyancy modules keep the high voltage cables in a so called ‘lazy wave’ to reduce tension and stress
