Tetrapod piled jacket (TPJ) foundations that support offshore wind turbines (OWTs) tend to be subjected significant torque is caused by eccentric loading from wind, waves, or accidental vessel impact. This paper presented a comprehensive three-dimensional (3D) numerical analysis investigate TPJs performance under torsional loading, which considered the distribution of local and rotation over pi...

Most of the offshore wind turbines (OWT) recently installed in Europe, China and North America are shallow water. However, unlocking full potential OWT lies deeper waters. Jacket substructures have presented themselves as a reliable foundation concept for transitional water depth. This study focuses on structural static dynamic analysis traditional jacket (with X K bracing) patented three-legge...

Abstract Accuracy in analysing the integrity of a structure is critical for determining structure’s fitness service and reliability status. Today, variety techniques approaches are applied, including use data science applications. Data synthesis computer science, mathematics, statistics. Meanwhile, susceptible to mix statistical technical design uncertainties that may remain flexible as long ca...

As a modern infrastructure for offshore oil and gas resources development, platforms have many advantages, such as high efficiency, concentration, flexibility, repeatability. At the same time, its upper module environment is bad, equipment numerous, has very big risk. In case of fire explosion other accidents, it difficult to get timely rescue. Therefore, risk assessment platform necessary. Thi...

This study investigates the seismic response of a horizontal axis wind turbine on two bottom-fixed support structures for transitional water depths (30-60 m), a tripod and a jacket, both resting on pile foundations. Fully coupled, nonlinear time-domain simulations on full system models are carried out under combined wind-wave-earthquake loadings, for different load cases, considering fixed and ...

Offshore platform installation is associated with several inherent risks arising from majorcritical safety challenges such as fires, explosions, blowouts, falling objects, earthquake, extreme weather,and impact from moving objects such as helicopters or ships. These critical problems are due largely to designerrors or inadequacies, and poor maintenance. The safety challenges highlig...
