Modelling the variation of suction pressure during caisson installation in sand using FLAC3D [PDF]
Ships and Offshore Structures, 2017 A suction caisson is an upturned ‘bucket’ of cylindrical shape made from steel. This type of foundation has been very popular in the oil and gas industry and the current trend is to extend its use to offshore wind farms. Seepage conditions play a pivotal

Penetration and Pullout Capacity of Low-Skirted Suction Caissons
Shock and Vibration, 2021 The bearing capacity of suction caissons is the key to the design of offshore structures. A new type of cross-shaped low-skirted suction caisson is invented to effectively improve the bearing capacity, considering inevitable “soil plug” phenomenon.
