Abstract

Today, wind energy offers the most competitive production prices for renewable energy. Therefore there are strong political and industrial forces, especially in northern Europe, which support the development of the offshore wind industry. The present paper presents the results of drained tests on offshore bucket foundations for wind turbines in saturated dense sand. The bearing capacity of bucket foundations subject to combined loadings which are of interest particularly to the offshore geotechnical engineers, were calculated and found to be largely dependent on embedment ratios and load paths. Based on the results of the analyses, new failure criteria are calibrated for bucket foundations, in contrast to previous studies using the failure envelope approach which have suggested that yield surface is constant in shape.

An Experimental Study of the Drained Capacity of Bucket Foundations for Offshore Applications

Chicago, Illinois

Today, wind energy offers the most competitive production prices for renewable energy. Therefore there are strong political and industrial forces, especially in northern Europe, which support the development of the offshore wind industry. The present paper presents the results of drained tests on offshore bucket foundations for wind turbines in saturated dense sand. The bearing capacity of bucket foundations subject to combined loadings which are of interest particularly to the offshore geotechnical engineers, were calculated and found to be largely dependent on embedment ratios and load paths. Based on the results of the analyses, new failure criteria are calibrated for bucket foundations, in contrast to previous studies using the failure envelope approach which have suggested that yield surface is constant in shape.
