Offshore jacket platform foundation engineering is regarded as the most important and difficult content in offshore platform construction, therefore, the quality in detection of pile foundation is particularly critical. High strain dynamic test has been applied to dynamically monitoring the installation of underwater foundation pile in a developing project of Li Sui gas field in the East China Sea. This is the first test in China and is very challenging for application of this technique to underwater piling. Test procedure and characteristics are discussed and summarized. Field data are analyzed with software CAPWAP. According to the results from CAPWAP analysis, the pile integrity is good.
