PO175: Closing the loop: Rethinking Offshore Wind Decommissioning
Silvan Slijpen, Commercial Manager, Heerema Engineering Solutions B.V.
Abstract
With an operational lifecycle of offshore wind farms of approximately 30 years, the offshore wind industry is now approaching a new phase: decommissioning. By 2040, in Europe alone, approximately 1,000 turbines will have reached the end of their original engineering lifetime, with this number rapidly increasing to 6,000 by 2050. Despite over a decade of offshore wind development during which the installation process has seen significant efficiency improvements, the industry has yet to undertake the full decommissioning of a large-scale offshore wind farm. The scope of removal is governed by a combination of national and international regulations. These frameworks continue to evolve, and requirements vary across projects and jurisdictions. This dynamic regulatory landscape introduces risks for developers and contractors, particularly in shaping market strategies and investment decisions, potentially deterring new developments. The offshore wind industry is familiar with major component replacement (MCR), typically involving smaller-scale operations that exclude foundations. Where MCR is applied, it often follows a reverse installation methodology. However, this approach may not be optimal for large-scale decommissioning. As such, the industry still needs to develop and adopt efficient, scalable strategies for the removal of wind turbine generators (WTG) and their foundations. This research consists of an evaluation of different decommissioning methodologies and aims to evaluate these through logistical modeling. The outcome of this research is a description of decommissioning methodologies and the associated logistics, providing the basis for cost estimation of decommissioning and reducing the risk of uncertainty.
