Abstract: The results obtained from a field testing campaign on laterally - loaded monopiles , conducted at a dense sand site in Dunkirk , Northern France are described . These tests formed part of the PISA project on the development of im proved design methods for monopi le foundations for offshore wind turbine s . Results obtained f r o m monotonic loading tests on piles of three different diameters (0.273m, 0.762m and 2 .0 m) are presented . The pil es had aspect ratio s ( L / D ) of between 3 and 10 . The tests consisted principally of the ap plication of monotonic load s , incorporating periods of held constant loa d to investigate creep effects . T he influence of loading rate was also investigated . Data are presented on the overall load displacement behaviour of each of the test piles. M easured data on bending moments and inclinations induced in the pile s are also provided . Inferences are made for the displacements in the embedded length of the pile s . The se field data wi ll support th e development of a new 1D modelling approach for the design of monopi le foundations for offshore wind turbines. They also form a unique database of field measurements in a dense sand, from lateral loading of piles at a vertical distance above the ground surface.
