Vattenfall, IQIP & EnBW deploy EQ-Piling for offshore monopile installation

Offshore wind energy, marine construction, and foundation installation technologies require methods that meet strict environmental and operational constraints. In this context, IQIP, together with EnBW and Vattenfall, is advancing EQ-Piling technology with its first full-scale offshore monopile installation at the Dreekant wind farm site in German waters.

The project marks a transition from inshore demonstration to offshore validation, following earlier trials at Maasvlakte 2 in Rotterdam. The upcoming installation represents a key step toward commercial deployment of a foundation installation method designed to reduce underwater noise and carbon emissions.

Full-scale offshore validation of EQ-Piling
The monopile installation will be carried out using the floating installation vessel Orion, operated by DEME. The installation is planned as a demonstration to validate system performance under real offshore conditions, subject to final permitting.

A central objective is to demonstrate reduced noise levels during pile installation without the need for bubble curtain systems, which are commonly used to mitigate underwater noise but require additional vessels and energy consumption.

Reduced environmental impact during installation
EQ-Piling is designed to address environmental constraints associated with offshore wind construction. By minimizing installation noise, the technology supports compliance with marine environmental regulations, particularly those aimed at protecting marine life.

In addition, eliminating the need for auxiliary noise mitigation systems reduces operational complexity and associated CO₂ emissions. This contributes to lower overall environmental impact during the installation phase of offshore wind projects.

Consortium approach for technology validation
The project is supported by a consortium involving IQIP, EnBW and Vattenfall, with each partner contributing to the development and evaluation of the technology. Vattenfall will use data from the installation to assess potential application in future offshore wind developments.

As the project developer, EnBW provides the Dreekant site and supports the permitting process, enabling full-scale testing within a commercial project environment.

Toward scalable offshore wind foundation solutions
Following successful offshore validation, EQ-Piling is expected to be deployed in future wind farm projects. The technology aims to provide a scalable alternative to conventional monopile installation methods, combining reduced noise emissions with lower carbon intensity.

By integrating environmental considerations with installation efficiency, the project reflects ongoing efforts within the offshore wind sector to develop more sustainable foundation technologies while maintaining performance and reliability.
