Study of a monopile with pre-tensioned tethers for offshore wind turbines at deeper waters Proc. Inst. Civ. Eng. Marit. Eng. (IF 2.7) Pub Date : 2023-07-17 Mohd Ishtiyak, Arunjyoti Sarkar, Tiago Fazeres-Ferradosa, Paulo Rosa-Santos, Francisco Taveira-Pinto, Rui Figueiredo, Xavier Romão
Currently, monopiles are the industry's first choice to support offshore wind turbines (OWTs) due to the complexities associated with fabrication, transportation and installation of various foundation solutions. These are, however, considered suitable for water depths up to ∼30–35 m, beyond which they become massive and complex to handle. Increasing the application range of monopiles without making

Offshore wind turbines are often built on large-diameter monopile, which are exposed to lateral loads and overturning moments from wind and wave action, which is cyclic in nature. In this work, an attempt was made to examine the influence of embedded length on monopile behaviour using finite-element analysis (Plaxis 3D). The developed model was validated using a centrifuge test conducted on monopile

Dynamic response of offshore wind turbine monopile foundation under wind–wave loads Proc. Inst. Civ. Eng. Marit. Eng. (IF 2.7) Pub Date : 2023-04-27 Godfred F. Akwaa, Meng Gao
Physical experiments provide the best representation of foundation behaviour in any environmental conditions offshore; however, they are very costly, especially since the on-site conditions vary. Hence, it is not a cost-effective approach. In contrast, numerical modelling is relatively cheaper, but requires long computation time and a high level of expertise to perform a successful numerical calculation

Local overshoot and wind effects on wave overtopping at vertical coastal structures Proc. Inst. Civ. Eng. Marit. Eng. (IF 2.7) Pub Date : 2022-11-29 Swapnadip De Chowdhury, Jian G. Zhou, Anatoliy Khait, Derek Causon, Ling Qian, Clive Mingham, Tim Pullen
Wind effects on wave overtopping over a fully impermeable vertical sea wall were studied numerically using the open-source computational fluid dynamics library OpenFoam. A pressure gradient correction term was incorporated in the momentum equations. In recent studies, it was found that, in the absence of wind, an increase in wave steepness results in a reduction of wave overtopping. This is related

A new method for predicting the extreme dynamic responses of wave energy converters Proc. Inst. Civ. Eng. Marit. Eng. (IF 2.7) Pub Date : 2021-09-10 Yingguang Wang
The copula-based environmental contour approach in the existing literature is only ‘partially’ non-parametric. Theoretically, the derived environmental contours from this ‘non-parametric’ copula-based approach will still be somewhat rigid. Optimally, the environmental contours for a specific ocean site should be developed based on a joint model of the environmental variables and the joint model should
