Project Description

Within this joint research project scientists of the University of Duisburg-Essen are working on the sub-project SiEWin (safety and efficiency of a multipurpose ship for maintenance and repair of offshore wind turbines in seaways). A boundary element method for the calculation of seakeeping and maneuvering is further developed towards typical scenarios of multipurpose service vessels for offshore wind turbines. The method is extended to calculate safety relevant issues of service vessels (stability, loads, etc.) and to design jack-up leg systems for “semi-jack-up” and full “jack-up” state. Also the multipurpose service vessel, designed within this joint research project, will be optimized with spot on energy efficiency during operation by using the developed numerical method. In addition, structural analyses for the jack-up legs and the ships’ structure are performed.
