Large-Scale Tests of Suction Buckets Reveal Increased Tensile Capacity

Wind Industry Profile of

Fraunhofer IWES tested two large-scale suction buckets in a 1:5 scale in early 2018. The physical experiments at the Test Center for Support Structures in Hanover (TTH) are the first of their kind in Germany.

The test results confirmed the enormous potential of this foundation concept for reliable and cost-effective deployment in offshore wind farms. Within the experimental work the IWES researchers were also able to quantify an effective temporary increase in tensile capacity during storms. For manufacturers, this means the possibility of material savings for the entire construction without compromising stability. The so-called “suction buckets” have been used successfully in the oil and gas industry. The offshore wind energy sector will see this year... ... More: Official Press Release Fraunhofer IWES
