Helgoland Harbour South Quay
New quay and site preparation for the expansion to form a hub for offshore windfarms and for supply to the island
Out in the North Sea, roughly 40 km north of the island of Helgoland, are three offshore windfarms. The district of Helgoland sought to expand the transhipment areas in the south harbour complex to provide a port supporting the operations and maintenance of the windfarms and also in order to relocate incoming island supplies to the south quay. Alongside public access and connections to the road network, the existing quays were replaced by a new and expanded to meet the needs of the windfarm operators and freight handling for the island. The harbour basin was then dredged to achieve the required water depth. In addition, contaminated sedimentation and bedrock layers had to be excavated.
The new quay was designed as an attachment to the old quay. The newly created transhipment areas have a total size of 3,000 m² and run up to the service buildings with the manufacturing and storage facilities. The particular challenges of the project included the weather condition, the existing, unstable quay, the extensive prospecting and recovery of explosives, not to mention optimization of the construction site and logistics planning to reflect the island location.
