Posters
Come meet the poster presenters to ask them questions and discuss their work
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!
PO073: A combined Accessibility and Workability quantitative analysis of a 15MW floating wind turbine
Thor Snedker, Team Lead - Modelling & Methods, PEAK Wind
Abstract
The Floating Offshore Wind (FOW) industry is set for rapid expansion with an estimated 3-4 GW operational by 2030[1]. While FOW developments can leverage O&M strategies from bottom-fixed wind (BFW) projects, FOW plants require unique attention in terms of accessibility and workability. That is, transferring personnel to the floating platform and feasibility of working on the floating structures. A structured method for evaluating accessibility and workability due the inherent 6 degree-of-freedom nature of FOW and site specific met-ocean conditions are presented in this work.Despite the limited number of commercial projects and operational FOW demonstrators, it is imperative to iteratively evaluate the accessibility and workability for all project phases starting from tendering phases through operations. In tendering phases where supplier selection takes places the various concepts of floating foundations can with benefit be evaluated as the choice impacts OPEX and hence business case. Throughout pre-FEED and detailed design, the selected concept can be optimized for accessibility by secondary steel-design of access ladders in relation met-ocean and foundation concept. Simultaneously accessibility and workability should be considered through negotiation on Service and Maintenance Agreements (SMAs). In operations the boundary conditions for accessibility and workability can be used to make informed and optimized maintenance strategies and schedules. Firstly, a combined accessibility and workability method is established which minimizes the computational effort by virtue of an algorithm looping over sea-states and associated probability of Hs, Tp and wave heading (WH) (outer loop) and defining the accessibility and workability limit envelopes (inner loops). Secondly, case study analysis and results are presented for accessibility and workability based on the UMaine VolturnUS-S Reference Platform with the IEA 15MW reference Wind Turbine Generator (WTG) and Service-Operation-Vessel (SOV) for a limited range of met-ocean conditions from US East Coast data taken from hourly met-buoy data.
