In this paper, integrated analyses performed in SIMA are compared against experimental results obtained using real-time hybrid model testing (ReaTHM®) carried out in the ocean basin facilities of MARINTEK in October 2015. The experimental data is from a 1:30 scaled model of a semi-submersible wind...

For shallow and intermediate water depths, large monopile foundations are considered to be promising with respect to the levelized cost of energy (LCOE) of offshore wind turbines. In order to reduce the LCOE by structural optimization and de-risk the resulting designs, the hydrodynamic loads must be...

Numerical simulations of wind turbines using engineering models for aerodynamic loads are an important design tool. The most common aerodynamic models include the blade element/moment (BEM) method, with numerous corrections for tip loss, hub loss, dynamic stall, and dynamic wake, as well as the...

The objective of the present work is to examine the effects of different methods of modeling the external wind field on the estimated tower fatigue damage of a spar-type floating offshore wind turbine. In the present work, three types of wind inflow (constant, temporally varying,and temporally and...
