Design and Analysis of Jacket Substructures for Offshore Wind Turbines
This study focused on investigating various existing types of offshore jacket substructures along with a proposed twisted-tripod jacket type (modified jacket (MJ)-structures). The architectures of the three-leg structure, as well as the patented twisted jacket structure motivated the design of the proposed MJ-structures. The dimensions of the structures were designed iteratively using static st...
متن کاملFatigue Reliability of joint connections in support structure of offshore wind turbines
Fatigue Reliability of joint connections in support structure of offshore wind turbines by Anh Quang Mai This study is my initial attempt to investigate the evolution of fatigue reliability of welded joints in offshore wind turbine support structures. This information is crucial to update the inspected data (crack sizes, probability of crack detection) to make the plan for the next inspection a...
متن کاملOPTIMAL DESIGN OF JACKET SUPPORTING STRUCTURES FOR OFFSHORE WIND TURBINES USING ENHANCED COLLIDING BODIES OPTIMIZATION ALGORITHM
Structural optimization of offshore wind turbine structures has become an important issue in the past years due to the noticeable developments in offshore wind industry. However, considering the offshore wind turbines’ size and environment, this task is outstandingly difficult. To overcome this barrier, in this paper, a metaheuristic algorithm called Enhanced Colliding Bodies Optimization...
متن کاملDesign of support structures for offshore wind turbines
Offshore wind is the logical next step in the development of wind energy. With higher wind speeds offshore and the fact that turbines can be placed out of sight, offshore wind helps increase the amount of renewable energy signifi cantly. Offshore wind has been developed through pilot projects in the 1990s and has seen commercial development over the last decade. This chapter shows the developme...
متن کاملRefined Fatigue Analysis for Tripod Support Structure of Offshore Wind Turbine (OWT)
Fatigue design and certification of OWT is a special challenge. As the turbine manufacturers are reluctant to share detailed turbines information and the offshore contractors have not full knowledge of integrated OWT design, integrated and non-linear time domain simulations are too cumbersome. A simplified approach is proposed, that requires complete separation between turbine and support struc...
