Response of suction buckets in layered soils under storm loading

Research output: Chapter in Book/Conference paperConference paperpeer-review

Abstract

Layered soils are frequently encountered in intermediate water depths, where suction bucket jackets are considered an economically competitive foundation for offshore wind turbines. Permanent tilting can make the turbine inoperable, such that excessive differential movement between buckets must be avoided. This paper presents results from centrifuge tests designed to investigate the suction bucket response to sequences of storm loading in a clay over sand soil profile. Results indicate the suction buckets in clay over sand can sustain a 0 kPa mean stress with transient tensile loads reaching up to 1.9 times the tensile resistance with negligible uplift. For a mean compressive stress, the bucket experiences net settlement, even with excursions into tension reaching up to 2.8 times the tensile resistance.
