Design methods for pile installation e.g. cast insitu or full displacement driven piles are often used as the basis for the design of more advanced installation approaches such as push and rotate piles with cutting shoes (RCP). These approaches, though, do not reflect the variation in installation and the effects it may have on capacity when applied to RCP piles. Although continuous development and improvement of RCP pile design is ongoing, it was seen as valuable to explore current insitu test based design of offshore piles. This paper compares offshore CPT based pile design techniques with field measurements of pile performance. Results suggest improved prediction of shaft capacity when compared to SPT based methods but with mixed performance for end bearing prediction. Attempts to predict installation torque using a method developed from DEM modelling showed some success irrespective of the complexity of installation using water injection and surging
