Methods for computation of wave forcing and the resulting motion of a slender offshore floating structure","description":"Academic Paper from the year 2014 in the subject Engineering - Civil Engineering, grade: 1,0, University of Hannover (A\u0026amp;M University Texas, Ludwig-Franzius-Institut f? Wasserbau, ﾄstuar- und K?teningenieurwesen), language: English, abstract: This thesis investigates how wave loads act on an OC3 Hywind spar-buoy. The author analyzes the resulting motions of the support platform. This work also contains a detailed presentation of the topic with useful additional information and graphics. Unlike fossil fuels (like oil, coal and natural gas), wind energy is a renewable energy resource. Since winds at sea are stronger and more consistent than onshore winds, the demand for offshore wind turbines has increased over the last years. As energy can be produced more efficient in deeper water, several floating offshore wind turbine constructions, such as the OC3 Hywind spar-buoy, have been proposed. The design of floating wind turbines depends on the simulation of the system behavior caused by exciting forces. A general overview of regular and irregular waves as well as hydrostatic and hydrodynamic loads acting on floating structures is given in chapter 2. Furthermore, essential formulations for calculating motions of FOWTs are given at the end of this chapter. Since all simulations carried out in this thesis are based on the OC3 Hywind concept, detailed information about this floating wind turbine model are given in chapter 3. Three different methods are used for the estimation of wave induced loads and motions. Section 4 describes a modified Morison formulation in the time domain which is applied by the commercially available software MATLAB. On the basis of the diffraction theory the commercial offshore software package SESAM simulates wave excitation forces and responding motions which are presented and discussed in chapter 5. The third method is the open source code FAST that computes wave induced loads and motions based on the first-order potential theory and Kane\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Olga Glkner\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3668754799\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783668754799\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Grin Verlag\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 08\/01\/2018\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 152\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.46lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 8.27h x 5.83w x 0.35d","brand":"Olga Glkner","offers":[{"title":"Paperback","offer_id":43940838572287,"sku":"9783668754799","price":86.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/products\/img_756307a0-cf47-4bb6-b0c5-fa29285b95ca.jpg?v=1681449460","url":"https:\/\/www.whiterainbookhouse.com\/products\/wind-energy-methods-for-computation-olga-glckner-9783668754799","provider":"WR Book House","version":"1.0","type":"link"}
