The objectives of annex 30 of the IEA (Offshore Code Comparison Collaborative Continuation) are similar to those of annex 23 as it is a continuation of that project. Annex 30 especially aims to focus on the study of two types of offshore wind turbines: a jacket type fixed structure (Phase 1) and a semisubmersible type floating structure (Phase II). If experimental data or open measured data can be obtained, a third phase would be created to compare the simulations with these data.
CENER-ADA participation: Phase II: Semisubmersible modelling. Participation in the model development and in the simulation of the simulation cases. The code used will be a FAST version modified by CENER and coupled to a propriety code for the dynamic simulation of mooring lines.
