Senior Engineer Vattenfall
Johan Toftekær

Johan Frederik Toftekær is a Senior Engineer at Vattenfall, where he leads the development of in‑house tools for design, digital twin, and asset integrity of offshore wind turbine support structures. With a PhD in structural dynamics from the Technical University of Denmark, he brings deep expertise in structural damping, turbine reliability, and lifecycle performance. Johan’s work advances the practical implementation of digital twins to optimize turbine support structure design, monitor real‑time integrity, and extend lifetime of large‑scale offshore wind farms.

Offshore Foundations: Day 2 - 28/08/2025

13:05 State-of-the-Art Virtual Sensing for Offshore Wind Turbines

• The derivation of virtual sensing method based only on measured accelerations.

• Separation of translation and inclination contributions to measured accelerations.

• Quantification of the uncertainty of virtual sensing by benchmarking with local strain

gauge measurements.

• Quantification of design load case specific uncertainties.

• Perspectives on the use of virtual sensing for operation, maintenance and lifetime

extension of Vattenfall’s offshore wind fleet
