Abstract

Floating renewable energy generates very high structural accelerations during storm events and the design of anchoring systems to resist these extreme loads appears to be very costly and inefficient. This study explored a potential strategy for innovation of the current practice through the application of active suction on caisson foundations to resist the most extreme loads temporarily. The differential pressure due to suction increases the tensile capacity beyond that mobilised by friction at the soil-skirt interface under drained loading. The physical mechanism mobilised with active suction was investigated through extensive physical modelling complemented with numerical and analytical analyses.
