As the new causeway out to Granite Island at Victor Harbour is now completed, the old causeway needed to be disassembled and removed.

Ecospec Australia have been awarded the contract to disassemble and remove the old causeway. They are doing this using a spider crane on jack-up piles which rest on the seabed.

Magryn undertook a review of their methodology and the transfer of loads from the spider crane feet to a support frame to the jack up the piles, to enable EcoSpec to safely remove the causeway structure.
