Research for Vertical Bearing Characteristics of Top Grouting Jacket Pile Foundation in Clay Foundation

南方能源建设, 2023
[Introduction] The top grouting jacket pile foundation is a new type of foundation application for offshore wind power jackets on clay seabed. Since the grouting section can bear some loads, its stress and deformation mechanism is significantly different

Impact of Design Parameters on the Dynamic Response and Fatigue of Offshore Jacket Foundations

Journal of Marine Science and Engineering, 2022
The lifetime of offshore foundations is governed by a combination of harsh environmental conditions and complex service loads. The fatigue limit state (FLS) analysis needs to be performed in the time domain to capture the complex phenomenon.

Numerical simulations of towing a jacket foundation with triple buckets

IOP Conference Series: Materials Science and Engineering, 2023
Abstract Offshore wind energy is developing fast as a promising renewable energy resource that can be helpful in achieving the global net-zero emissions goal. In recent years, offshore wind turbine projects have gradually moved towards far-offshore sea areas, where massive jacket foundations with suction buckets are suitable options.
