This paper describes axial load tests on three full-scale driven precast piles in the Netherlands. The piles were founded in dense to very dense river-deposited sands, a soil that is widespread across the Dutch North Sea sector. The deposit is characterised by cone penetration test (CPT) tip resistances of up to 90 MPa and offers a detailed insight into pile response in realistic offshore conditions. Each test pile was incrementally loaded to failure under compression, while fibre optic sensors measured the changing deformation of the pile. The analysis and interpretation of the load test data focussed on how the three slender piles behaved at large shaft and base resistances. Notably, the piles mobilised base and shaft resistances greater than currently prescribed limiting resistances in design standards, thereby highlighting some overconservatism present when designing piles in dense sand.

|OSIG is the longest standing international conference series of this type. It brings together the offshore Geotechnical, Geophysical & Geoscientific industry & academic communities to share the latest research, knowledge and experience. Building on the success of previous events, the programme will encompass a wide range of technical themes, aiming to attract hundreds of international delegates. Social and networking events are also being programmed, culminating in a dinner and evening event at the Natural History Museum, London, with an exciting guest speaker.
