... of offshore wind turbines is growing considerably and more preparation and competence are required in association with new projects. In this paper, a review of existing decommissioning methods for offshore bottom-fixed wind turbines is provided first. The removal of wind turbines’ foundation and transition...

... Abstract The interaction of sea ice with offshore structures is an important engineering concern in ice-infested areas. This paper presents a procedure to evaluate ice loads acting at the sloping offshore wind turbines in the Estonian territorial waters at the Baltic Sea, where the waters...

... Engineering Research Center Dalian University of Technology 116024 Dalian, China weishi@dlut.edu.cn ABSTRACT Although the installation of offshore wind turbines takes place in calm seas, successful mating of wind turbine components can be challenging due to the relative motions between the two mating parts...

... been detected when this method is used for offshore structures that consider survival strategies e. g. offshore wind turbines (OWT). Lastly, a modified ECM procedure (MECM) has been developed with the purpose to bypass the limitations of the traditional ECM. This method is based on short-term...

... Luneort 100, 27572 Bremerhaven, Germany ABSTRACT The trend towards larger offshore wind turbines (WTs) im- plies the need for bigger support structures. These are commonly derived from existing structures through upscaling and subse- quent optimization. To reduce the number of design steps, this work...

... responses of the wind turbine due to the effects of different wind-wave load combinations and soil conditions have been investigated and discussed.
