Reliability-based design optimization of offshore wind turbine support structures using analytical sensitivities and factorized uncertainty modeling

In this paper we demonstrate that efficient reliability-based optimization for offshore wind turbine support structures is feasible.

Grand challenges in the science of wind energy

In this article we outline three interdependent, cross-disciplinary grand challenges to realize the potential of wind to serve the global demand for clean energy. Our contribution is a review of the challenges for offshore wind.

Structural monitoring for lifetime extension of offshore wind monopiles: Verification of strain-based load extrapolation algorithm

Lifetime extension needs low-cost assessments that can identify the remaining useful life of offshore wind monopiles. A novel concept for load monitoring was developed that only needs strain gauges installed at one level of the support structure.

On gradient-based optimization of jacket structures for offshore wind turbines

During the bidding or early design phases of jacket structures for offshore wind turbines it is important to quickly obtain near-optimal designs with costs indicative of the final support structure. This paper shows and compares three possible approaches.

Wasserstein distances in the analysis of time series and dynamical systems

A new approach based on Wasserstein distances, which are numerical costs of an optimal transportation problem, allows us to analyze nonlinear phenomena in a robust manner.
