Offshore wind turbine (OWT) support structures are subjected to non-proportional environmental wind and wave load patterns with respect to increases in wave height and with respect to wind and wave combined loading. Traditional approaches to estimating the ultimate capacity of offshore support structures are not ideally suited to analysis of OWTs. In this paper, the concept of incremental wind-...

 Choosing appropriate foundations for supporting offshore wind turbines is one of the uncertainties in the future rounds of offshore wind power development. Offshore wind turbines are dynamically sensitive structures as the global natural frequency of the whole system is very close to the forcing frequencies (due to the environmental loads and the associated frequencies due to the rotor). This...

Offshore renewable energy developments (OREDs) are projected to become common in the United States over the next two decades. There are both a need and an opportunity to guide efforts to identify and track impacts to the marine ecosystem resulting from these installations. A monitoring framework and standardized protocols that can be applied to multiple types of ORED would streamline scientific...

Several alternative engineering models are available for the use in analysis of offshore wind turbines. However, it is not always clear which will yield most accurate or sufficiently conservative results. This paper investigates effect using two soil-structure interaction and coherence models. The focus on assessing how these modelling choices influence predicted long-term fatigue damage suppor...

A numerical investigation of hydrodynamics around a monopile foundation is presented in the paper. An open-source CFD program REEF3D used for present study. The model solves Reynolds-averaged Naiver-Stokes equation with k-w turbulence closure to obtain flow hydrodynamics. code utilizes staggered cartesian grid system. Also, Message Passing Interface (MPI) based parallelization domain decomposit...
