... ABSTRACT: Current design methods for monopiles – the dominant foundation type for offshore wind turbines – do not properly account for cyclic loading and rate effects. The PICASO (Pile Cyclic AnalySis: Oxford and Ørsted) project aims to address this shortcoming by developing a new design...

... ABSTRACT: Most offshore structures are founded on large driven piles and reliable prediction of their axial capacities is often a key design requirement. When compared to the ICP-05 and UWA-05 design methods, the recent Unified CPT based design approach for sands gives broadly similar...

... outside of their original calibration spaces. New, robust and adaptable methods are required to predict SRD for current offshore pile geometries. An optimisation framework to update uncertain model parameters in existing axial static design methods to calibrate SRD is described. The optimisation...

... in dense sand. 1 Introduction The new ISO/API design method (Lehane et al., 2020) has changed how driven piles under axial loading are designed offshore. To calibrate the design method, high quality static load tests were compiled (Lehane et al. , 2017), building on previous databases such as the ZJU...

..., the suitable design approach is cho- sen based on the available soil. 2.1 API RP 2A-WSD working stress design method Upon availability of soil properties such as undrained shear strength (Su) or friction angle ( '? ), API 2A-WSD (2000) presents the following meth- odology for pile capacity assessment...

... fracturing. THE USE OF ICP DESIGN METHODS AS A PREDICTOR OF CONDUCTOR DRILL-DRIVE INSTALLATION Robert Overy and Paul Sayer Shell UK Ltd, UK Abstract This paper deals with the design and installation of the foundation piles for the Skiff platform in the UK southern North Sea. The structure is novel because...

.... In the early 1980s Shell U.K. Exploration and Production (Shell Expro) identified a need to improve design methods for its offshore structures, especially those relating to pile capacity in dense sand. To that end Shell Expro commis- sioned a major review of end bearing, for which a sum- mary has been...
