Piles for Offshore Wind

Pin Piles for Offshore Wind Jacket Foundations and Substations

We also offer the production of piles in addition to jacket components in order to comprehensively serve customer projects. These are required in large quantities for the attachment of three- or four- legged jackets in the seabed. Due to various external influences, such as the conditions of the seabed or currents, individual requirements arise for each project. EEW is able to install a large number of different attachments to the piles thanks to our extensive machinery and the precise handwork of our employees. This allows us to offer our customers unique solutions. Large amounts of piles are necessary in order to attach offshore foundations like jackets to the sea floor. EEW is able to produce large quantities of piles in short time periods in order to support a smooth and quick installation process for our customers.

Pre-piling

Offshore wind foundations are usually fastened by using what is known as pre piling. For this purpose, we provide the piles with weld beads as well as level marking to make installation at sea as easy as possible.

Post-piling

To install substations for the offshore wind industry in the seabed, a common method is post piling by using pile sleeves or driving a pile through the jacket leg. EEW offers its customers a comprehensive portfolio consisting of pin piles and pile sleeves as attachment parts for jackets.

Ready-for-installation

We manufacture all pin piles ready-for-installation to support executing final assembly on-site as easy as possible. In addition, we have the option of producing piles with two longitudinal seams at all locations. This significantly shortens the supply chain for our customers, resulting in considerable cost and time savings.
