Hundreds of steel and reinforced concrete piles were removed to make way for the construction of the new LNG marine terminal.
Piles were located in depths of water up to 30 meters. CMP worked from barges to operate cranes and specialised water cutting equipment to break the piles off 1 meter below the seabed.
Special underwater cutting jets were used to clear soft materials from the bed, and divers were deployed to cut and remove larger obstructions.
A grab was sunk around each pile to allow heavy materials to be excavated so that piles could then be cropped. Where mechanical demolition was not possible CMP deployed divers with underwater cutting equipment to free the piles.
Piles were cut free of the bed and transported ashore where the materials were broken down and recycled.
