The 2025 Offshore Technology Conference (OTC) grandly opened on May 5 at NRG Park Convention Center in Houston, USA. Dr. Pan Xujie, the principle engineer of WNE Wind Product Center, is invited to attend the conference and delivered a technical speech titled “Buoyant Tower Experimental and Numerical Studies on Anti-Rotation Behavior of Suction Caisson Foundation”.
As WNE’ patented offshore engineering technology, the buoyancy tower platform has drawn extensive industry attention for its unique application of Suction Caisson Foundation (SCF) in marine foundation design. Having undergone over a decade of operational verification and field measurements in actual offshore projects, WNE presented the bearing mechanism of SCF under rolling conditions at last year’s OTC conference. Building upon this achievement, Wison’s wind power center has further investigated the bearing mechanisms and foundation damage mode of SCF under torsional loads. The team has proposed an innovative torsion-resistant suction caisson design, validated through systematic numerical simulations and centrifuge tests to confirm its feasibility.
Based on ten-year measurement data of the CX-15 buoyant tower platform, this study delves into the behavior of the unconventional anti-rotation SCF design, explored through a series of geotechnical centrifuge tests at an acceleration rate of 100 g. With the validation of this special SCF design, the technology will be integrated into Wison’s unique floating offshore wind turbines as well as floating substations, offering invaluable insights for enhancing design guidance.
The remarkable showcase of WNE at OTC not only demonstrated its technological leadership in the offshore engineering sector but also reflected its profound insights into industry development and unwavering commitment to continuous innovation. With the rapid development of clean energy sources such as offshore wind power, WNE is dedicated to driving groundbreaking advancements and transformative changes for global marine engineering.
