“…The following points can be obtained from the figure : (1) M x and M y have values of the same order of magnitude, but M y plays a dominant role throughout the traveling process of the typhoon. (2) The bending moments of blades 2 and 3 are basically the same. Markedly, the rotor is under the aerodynamic imbalance condition.…”

“…On average, nine typhoons land on the southeast coast of China every year [1]. Typhoons are intensive ocean forces that can destroy coastal properties or offshore engineering structures, leading to significant economic losses [2]. Generally, typhooninduced waves are characterized by extreme heights [3,4], which pose a substantial threat to the stability and structural integrity of floating foundations [5][6][7].…”

A typhoon is a restrictive factor in the development of floating wind power in China. However, the influences of multistage typhoon wind and waves on offshore wind turbines have not yet been studied. Based on Typhoon Mangkhut, in this study, the characteristics of the motion response and structural loads of an offshore wind turbine are investigated during the travel process. For this purpose, a framework is established and verified for investigating the typhoon-induced effects of offshore wind turbines, including a multistage typhoon wave field and a coupled dynamic model of offshore wind turbines. On this basis, the motion response and structural loads of different stages are calculated and analyzed systematically. The results show that the maximum response does not exactly correspond to the maximum wave or wind stage. Considering only the maximum wave height or wind speed may underestimate the motion response during the traveling process of the typhoon, which has problems in guiding the anti-typhoon design of offshore wind turbines. In addition, the coupling motion between the floating foundation and turbine should be considered in the safety evaluation of the floating offshore wind turbine under typhoon conditions.

“…Wave simulations were performed using WAVEWATCH III v5.16, developed by the National Centers for Environmental Prediction Environmental Modeling Center. This model has been validated in many previous studies and has been shown to realistically simulate the mean wave parameters and wave spectrum, especially under various TC conditions (Moon et al, 2003;Tolman et al, 2005;Fan et al, 2009;Montoya et al, 2013;Moon et al, 2016;Liu et al, 2017;Abdolali et al, 2020;Wang et al, 2020;Zieger et al, 2021). The spatial resolution of the current model was set to 1/12°x 1/12°(541 x 481), and the basic source term ST2 was used as the physics package (Tolman and Chalikov, 1996).…”

The maximum significant wave height (Hsmax) induced by a tropical cyclone (TC) can be estimated from an empirical fetch formula using the TC’s size, maximum wind speed, and translation speed, in which larger, stronger, and faster-moving TCs generally have higher the Hsmax. In the formula, the radius of maximum wind (RMW) has been widely used as the TC size parameter under the assumption that Hsmax is mainly generated by strong winds near the RMW. This study investigates whether RMW is the optimal parameter for determining TC-induced Hsmax through extensive wave model simulations for North Atlantic hurricanes from 1988–2017. The correlation analysis between the estimated Hsmax and TC size parameters revealed that the radius of the 34-kt wind speed (R34, r = 0.84–0.95) was much higher than the widely used RMW (r = 0.33–0.58), which suggests that R34 is a more important TC size parameter for determining TC-induced Hsmax than RMW. This result can be explained by the fact that R34 showed a significantly higher correlation (r = 0.96) than RMW (r = 0.31) with cumulative TC wind speeds, which are closely related to Hsmax. These findings also indicate that the TC-induced Hsmax is more affected by the region containing moderately strong winds outside the TC than by the region of maximum wind speed near the RMW. Our paper provides additional insight into the mechanisms by which extreme wave heights, which cause severe damage during TC passage, occur.

“…The wind field, as a driving factor, plays an important role in the simulation of typhoon waves. With the improvement of the accuracy requirements for typhoon waves in forecasting and post-forecasting modes, constructing a more accurate typhoon wind field model has become an important research topic (Rogers et al, 2007;Wang et al, 2020). This study introduces the Holland circular symmetric wind field model, superimposes the Holland wind field model and the moving wind field model to form a superimposed wind field model, and introduces an improved four-quadrant asymmetric wind field model based on the Holland model.…”

The East China Sea is an ocean region with frequent typhoons, typhoons are also the main reason for inducing typhoon waves. The complexity of typhoon waves is closely related to the complexity of typhoon wind field. In previous studies, symmetrical wind field models or superimposed wind field models were usually used to simulate typhoon waves. However, the actual wind fields are asymmetric, and the asymmetry is affected by many factors. Therefore, three wind field models are used to simulate the wind field of Typhoon Muifa that moved through the East China Sea. Moreover, the abovementioned wind field models are used to drive the third-generation wave model SWAN to simulate the wave field and wave spectrum of Typhoon Muifa. Studies show that the values generated by the asymmetric wind field model are most consistent with the actual measurement data. This is especially the case if the typhoon center is closer to the station. The accuracy of the typhoon waves simulated using the asymmetric wind field model is better than that of the other two wind field models. The asymmetric wind field can reflect the asymmetric characteristics of the typhoon well. The substantial wave heights on the right side of typhoon’s path are substantially higher than those on the left side of path. Additionally, the maximum wave spectral density and total energy of waves as simulated by the asymmetric wind field are both larger than those of the other two wind field models. Thus, the asymmetric wind field model is more suitable for the numerical simulation of typhoon waves in the East China Sea.
