N1 - Funding Information: Acknowledgements We would like to thank Roger Bullivant Limited (RBL) and particularly Jon Ball for their support, help and guidance throughout our many years of looking at piles. RBL continue support our work through sponsorship of current PhD student Yaseen Sharif. We would like to acknowledge the support of EPSRC for funding over many years that has contributed to our current level of understanding: EPSRC CASE for New Academics, EPSRC Supergen Windhub Call 2015: Grand Challenge project EP/N006054/1., EPSRC NPIF funded studentship with industry contribution—Screw piles in clay soils. More recently, facilities and staff have been supported by the EU through LUPS/ERDF/2013/10/1/0075 to create the Scottish Marine Renewables Test Centre for Materials & Foundations (SMART), 2017, EU H2020 Marie SkŁodowska-Curie Actions Individual Fellowships SAFS – Development of Screw Anchors for Floating marine renewable energy System arrays incorporating anchor sharing. H2020-MSCA-IF-2016, Grant no. 753156 (08/17-07/19). We would also like to thank many colleagues, students, technicians and research partnerships (Durham University and the University of Southampton, Industry: Cathie Associates, SMD, RBL, In Situ SI, Lloyd’s Register, Hereema Marine Contractors) that have contributed to the success of our ongoing work.

N2 - This paper details the work undertaken at the University of Dundee in the last 5 years to develop understanding of screw piles to allow them to be deployed offshore as an alternative foundation type to driven piles used in jacket structures. This has been prompted by several UK and European funded research initiatives to develop silent foundation techniques to mitigate affects on marine mammals and other animals. Current mitigation systems also have significant associated costs and questionable environmental credentials. Prior to starting this work, it was recognized that development would not progress unless the ability to predict installation requirements did not form an early part of the research investigation. This then led to investigation of methods to reduce installation requirements and development of new design approaches for the required new screw pile geometries. This paper details the progress of these investigations which are still ongoing.
