... mining ships. Extensive research has recently been conducted on moonpool characteristics. Fluid motion in moonpools can be categorized into two types: piston and sloshing. Fluid resonance occurs when the external load frequency matches the moonpool's natural frequency. Using potential flow theory, Molin...

... ABSTRACT To better understand the lateral bearing capacity and natural frequency of offshore wind turbine (OWT), a centrifuge test was carried out with monopile and high-rise pile cap (HPC) foundation. The effects of scouring depths on natural frequency and lateral resistance were investigated...
