computation of drift forces for dynamic positioning within the very early design stage of offshore wind farm Installation Vessels
ASME 2014 33rd International Conference on Ocean Offshore and Arctic Engineering, 2014Co-Authors: Philip H Augener, Stefan KrugerAbstract:The German government has decided upon the changeover from fossil and nuclear based electrical power generation to renewable energies. Following from this offshore wind farms are erected in the exclusive economic zones of Germany. For the transportation and Installation as well as the maintenance of the wind turbine generators very specialized Vessels are needed. The capability of dynamic positioning even in very harsh weather conditions is one of the major design tasks for these Vessels. For this reason it is important to know the external loads on the ships during station keeping already in the very early design stage. This paper focuses on the computation of wave drift forces in regular and irregular waves as well as in natural seaway. For validation the results of the introduced calculation procedure are compared to measured drift force data from sea-keeping tests of an Offshore Wind Farm Transport and Installation Vessel.© 2014 ASME

sea keeping analysis of an offshore wind farm Installation Vessel during the jack up process
ASME 2014 33rd International Conference on Ocean Offshore and Arctic Engineering, 2014Co-Authors: Philip H Augener, Hannes HateckeAbstract:Offshore wind farms are not planned in sheltered and shallow waters any longer. Especially in the North Sea there exist many approved offshore wind farm projects at water depth between 30 and 50 meters. In particular the Installation process of these projects is strongly influenced by weather conditions and the sea-keeping capabilities of the Installation Vessels. For reliable planning of the entire project, not only the weather statistics, but also the Vessel’s sea-keeping capabilities need to be known accurately. For this purpose different kinds of sea-keeping analyses can be conducted. In this paper a sea-keeping analysis is presented, where the focus is upon the jack-up process. For the numerical computation the sea-keeping code E4ROLLS is applied. The results of this sea-keeping analysis are operational limitations for the jack-up process, caused by two different criteria derived from jack-up classification requirements.Copyright © 2014 by ASME

Comparative evaluation of different offshore wind turbine Installation Vessels for Korean west–south wind farm
Production and hosting by Elsevier B.V. on behalf of Society of Naval Architects of Korea., 2016Co-Authors: Ahn Dang, Shin Sung-chul, Kim Soo-young, Kharoufi Hicham, Kim Hyun-cheolAbstract:AbstractThe purpose of this study is to evaluate various means of wind power turbines Installation in the Korean west–south wind farm (Test bed 100 MW, Demonstrate site 400 MW). We presented the marine environment of the southwest offshore wind farm in order to decide the appropriate Installation Vessel to be used in this site. The various Vessels would be WTIV (Wind turbine Installation Vessel), jack-up barge, or floating crane … etc. We analyzed the Installation cost of offshore wind turbine and the transportation duration for each Vessel. The analysis results showed the most suitable Installation means for offshore wind turbine in the Korean west–south wind farm
