A framework for analysis of pile run
A framework for analysis of pile run
Pile run prediction is of increasing importance in offshore wind as it is a threat to the integrity of the foundation, the installation equipment and the support vessel. There is a need for improved methodology for assessing the risk of triggering a pile run and the distance over which the pile might be running before the soil resistance is sufficient to stop it. The current approach, typically a factorization of the soil resistance to driving, has shown unable to predict accurately the extension of a pile run when triggered and could be unconservative in soils with a high sensitivity to the loading rate. The result of a literature review on rate-dependency behaviour of soils is presented after which a framework is developed for analysis of a rate dependent soil resistance, the framework is then applied to the case of a large pile run. Conclusions are drawn on the applicability of the proposed framework and additional research needed for further development.
