“…In order to accurately calculate the wind effect on the RNA, a comprehensive study regarding 3D aero‐servo‐elastic analysis is required. However, because neither such data are readily available nor such analysis is simply feasible, in this research, the effect of wind on the RNA is calculated using a scaling relationship based on Manwell et al Utilizing this relationship, the wind effect on any arbitrary wind turbine could be easily calculated based on a known wind turbine as follows:

\frac{T_{1}}{T_{2}} = {(\frac{R_{1}}{R_{2}})}^{2},

\frac{M_{1}}{M_{2}} = {(\frac{R_{1}}{R_{2}})}^{3} .

“…Finally, both wind turbines must be geometrically alike to the greatest extent. [27] Therefore, in this research, aerodynamic thrust and moment for the 5-MW NREL wind turbine are readily determined according to Leite, [28] which results in an acceptable approximation for the initial steps of designing offshore wind turbines. Because the extreme weather condition is the considered weather condition in this research, the wind turbine is assumed to be shut down so that the occurrence of undesired damages attributed to the high wind velocity could be prevented.…”

Summary Considering the size and dimension of offshore wind turbine structures, structural optimization of such structures, notwithstanding being outstandingly fruitful, is a tedious task. Nonetheless, in this paper, a metaheuristic algorithm named as colliding bodies optimization is employed when investigating the optimal design of jacket supporting structures for offshore wind turbines. The OC4 reference jacket is considered as the case study, validating the outcomes of this research. To do so, MATLAB is utilized in modeling the structure. The structural optimization is then performed when both ultimate limit state and frequency constraints are being considered. During the optimization process, the weight of the structure is approximately halved, and its first and second frequencies are kept within the considered soft–stiff range (0.21–0.32 Hz).

SUMMARYAs the size of wind turbine grows, the cost of the commonest tubular structural system will also increase because of the increasing cost of transportation, assembly, erection and servicing. A lattice-tubular hybrid structural system, which is composed of a four-angle cross-shaped lattice structure at the bottom and a tubular structure at the top, is proposed for large wind turbine systems. The welding processes can be totally avoided and the fatigue strengths effectively improved because all members can be assembled by bolts in site after cutting and drilling in the factory. The ultimate bearing capacities of combined cross-shaped members subjected to axial compressions are obtained by a series of numerical analyses. The column curve of four-angle-combined cross-shaped members is obtained by fitting numerical results with a piecewise function. The particle swarm optimization algorithm is adopted to optimize the shape and size of the lattice partition in this study. The constraints including stress, slenderness ratio and frequency are applied to find the minimum weight of the lattice partition in the hybrid tower. The optimal results show that the proposed structural system is feasible and can resolve the disadvantages of the traditional tubular system in the fabricating, mounting and transporting.
