We would like to invite you to come and see the posters at our upcoming conference. The posters will showcase a diverse range of research topics, and will give delegates an opportunity to engage with the authors and learn more about their work. Whether you are a seasoned researcher or simply curious about the latest developments in your field, we believe that the posters will offer something of interest to everyone. So please join us at the conference and take advantage of this opportunity to learn and engage with your peers in industry and the academic community.
On 9 April at 17:15, we’ll also hold the main poster session and distinguish the 7 best posters of this year’s edition with our traditional Poster Awards Ceremony. Join us at the poster area to cheer and meet the laureates, and enjoy some drinks with all poster presenters!
We look forward to seeing you there!
PO072: Floating offshore wind turbine alternative method to inclining test
Pierre-Alain Frémont, Hydrodynamics Engineer, SBM Offshore
Abstract
Most floater stability characteristics can be calculated from the geometric shape of the submerged part of the floater. However, stability is also governed by the actual location of the center of gravity which is estimated in the design phase. The purpose of the inclining tests is then to determine the vertical position of the center of gravity (KG) of the structure and to provide a final validation of the stability data. For conventional ships, inclining test procedure involves shifting weights and measuring resulting change in equilibrium heel angle. KG is determined from those measures using naval architecture principles of the metacentric height (GM). Considering the specificities of floating offshore wind turbine, this methodology may be inappropriate. Indeed, some floaters geometries do not allow shift of weight, and all the floaters are not equipped with ballasting system that could be used instead of weights. Furthermore, due to the wind turbine generator being located at very high elevation, FOWT KG is high compared to conventional ships, thus KG calculated with inclining test is assessed with important uncertainty. For those reasons, in scope of Provence Grand Large project (PGL), SBM Offshore/EKWIL proposed to use the KG assessed in weight control report demonstrating better accuracy than inclining test. The theoretical assessment is validated by lightweight survey and draft readings at different construction phases of the project.
