The PISA Project

The PISA (Pile Soil Analysis) project is a large-scale project funded through the UK Carbon Trust Offshore Wind Accelerator Project

The aim of this project is to develop an improved method to design laterally loaded piles specifically for use in the offshore wind sector. The design procedure should include evaluation of the ultimate lateral capacity of piles, effects of cyclic loading, and evaluation of stiffness and damping during operational conditions. The research project should result in a close form solution for accurately designing piles for offshore wind farms that can readily be implemented into current industry design standards. The project will involve the large-scale testing of monopile foundations at two test sites; at a sand test site and a clay site.

Following an international competition an academic work group led by the University of Oxford and including Imperial College London and the Geotechnical Research Group at UCD led by Dr. Ken Gavin have been appointed as the academic work group for the PISA project. Their role is to provide ideas, input, modelling, scope of work for instrumentation and testing, supervision of testing, analysis of the test results and research in support of the project.

Specifically Dr. Gavin’s group will use their experience of field testing and development of design methods to help achieve the ambitious aims of the project. The project starts on August 1st 2013 and runs for 18 Months.

Dong Energy Working to Cut Offshore Wind Cost by 40% This Decade
Washington Post (USA), 08/08/2013, via Bloomberg, Alex Morales

Dong Energy A/S, Denmark’s state-controlled utility, is leading a drive to cut offshore wind- power costs by as much as 40 percent by the end of the decade. Researchers at the University of Oxford, University College Dublin and Imperial College London are to help with the research.
