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!
PO079: Transportation and installation recommendation for a tension-leg platform floating offshore substation
Hongbiao Song, Global Technical Leader, Offshore Wind, GE Grid Solutions
Abstract
Today there is an emerging trend where more offshore wind farms are moving further offshore into deeper waters, the bottom fixed offshore substations are less feasible technically, logistically, and economically. There are quite a few pilot floating wind turbine projects in the world while there are no floating offshore substations except for one small Fukushima floating substation (66kV, 16MW) in Japan. For large commercial size floating wind farm projects in deep water areas, such as USA west coast, large size floating offshore substation (FOSS) is necessary to make the project viable. GE has worked with Genesis to develop a Tension-Leg Platform (TLP) Floating Offshore Substation (FOSS) solution (810MW, HVAC) for USA west coast with 1100-mter water depth. This concept design is based on the metocean data in Morro Bay Area, California. The 1100-meter water depth and swell metocean (long period wave) give rise to extra technical challenges for floating OSS design, especially for the dynamic cable design. As part of one complete FOSS solution, how to transport from fabrication and install FOSS at California west coast site has been investigated. This California site condition brings special challenges for the transportation and installation (T&I), such as the port infrastructure limitation, etc. The main purpose of this paper is to discuss the recommended T&I methodology for TLP FOSS, which includes the load-out, dry transport, discharge, anchor and tendon preset, wet tow, tendon hookup, and dynamic cable installation. The recommended T&I methodology is mainly based on the fabrication base case, that the FOSS topside has been integrated onto the hull at the fabrication yard.
