Wave Load Mitigation by Perforation of Monopiles
Journal of Marine Science and Engineering, 2020 The design of large diameter monopiles (8–10 m) at intermediate to deep waters is largely driven by the fatigue limit state and mainly due to wave loads.

Determination of stress concentration factors in offshore wind welded structures through a hybrid experimental and numerical approach [PDF]
, 2019 Offshore wind turbine (OWT) monopile support structures generally consist of steel cans connected together through circumferential welding joints. One critical factor to evaluate the localised increase in stresses is the stress concentration factor (SCF)

China Ocean engineering, 2022 The existing studies have primarily focused on the effect of cyclic load characteristics (namely, cyclic load ratio and amplitude ratio) on cyclic lateral response of monopiles in sand, with little attention paid to the effect of pile-soil relative ...

Optimization of monopiles for offshore wind turbines [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015 The offshore wind industry currently relies on subsidy schemes to be competitive with fossil-fuel-based energy sources. For the wind industry to survive, it is vital that costs are significantly reduced for future projects. This can be partly achieved by introducing new technologies and partly through optimization of existing technologies and design ...

Monopiles subjected to uni- and multi-lateral cyclic loading [PDF]
, 2017 Offshore wind turbines are subjected to significant environmental loads from a combination of current, wind and wave action. Under such conditions, the directions of these environmental loads vary over the service life of the structure and therefore the ...

Numerical Study on Lateral Response of Offshore Monopile in Sand under Local Scouring Conditions
Journal of Marine Science and Engineering, 2023 Currently, p-y models have been broadly adopted for estimating the lateral bearing capacity of large-diameter monopiles in offshore engineering. However, the existing p-y curves cannot reflect the effect of pile diameter D on the lateral response of ...

Dynamic Impedances of Offshore Rock-Socketed Monopiles
Journal of Marine Science and Engineering, 2019 With the development of offshore wind energy in China, more and more offshore wind turbines are being constructed in rock-based sea areas. However, the large diameter and thin-walled steel rock-socketed monopiles are very scarce at present, and both the ...

Journal of Marine Science and Engineering, 2021 The large-diameter monopiles are the most preferred foundation used in offshore wind farms. However, the influence of pile diameter and aspect ratio on the lateral bearing behavior of monopiles in sand with different relative densities has not been ...
