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!
PO074: WIND-bos Extendable Spar Dynamics and T&I Operations for a 25 MW WTG
Albert Meseguer, Lead Wind Turbine Egineer, BlueNewables
Abstract
The aim of this research is to showcase the achievements of the KSEI project, a consortium in between Spanish and Korean institutions, where the WIND-bos technology has been scaled up for a large offshore WTG of 25MW. The WIND-bos technology is a Floating Offshore Wind Platform (FOWP) of the type of extendable spar. The extendable spar is a specific spar design where the typically large operational draft of the unit can be reduced, adding value to the technology by reducing the Transport and Installation (T&I) operation limits such as port minimum water depths or minimum bollard pull capacity for towing conditions. The WIND-bos technology is composed of an upper Steel Tank (ST) with large bouyancy and a lower Counter Weight (CW) in concrete, filled with ballast water to lower the centre of gravity. The two bodies are joined by means of sliding steel legs that are extended once the platform is installed on site, allowing to have the counterweight lifted during the initial T&I operations and therefore considerably reducing the draft. This research work shows the main properties of the platform for a 25 MW Wind Turbine Generator (WTG) together with the specificities that make this platform design a polyvalent FOWP. First, the main steps of the T&I phases are showcased to provide with an idea of the overall perspective of the T&I operations procedure, from the load-out phase until the installation on site, and the low restrictions in terms of draft and bollard pull. Then, the dynamic response of the WIND-bos 25MW is presented for the driving Design Load Cases (DLCs) providing with a sense of the relatively small response to the environmental dynamic excitation forces, leveraging this way the high performance and stability of the WIND-bos design for such large WTGs.
