A case study : construction of bucket foundations for jackup ships
Jackup ships are built to transport wind turbines foundation between offshore logistics center and the installation site. It require sufficiently stable seabed next to quay walls. Otherwise jackup processes may reduce the stability of the quay wall and remained footprints of the legs could induce un...
