Kingston City Council have undertaken an upgrading of pleasure boating facilities in Mordialloc Creek. Part of the work was to replace the deteriorated existing seawall around Lambert Island.
To carry out this work we mounted our 50 tonne crawler crane on a 200 tonne capacity barge moored alongside Lambert Island. A 50 tonne capacity barge was used to ferry sheet piles to site and carry away the demolished old concrete panel wall.
The AU20 steel sheet piles were vibrated into place with a ICE416 vibro hammer driven by a 400 hp power pack mounted on the barge.
The entire worksite was surrounded by a floating silt boom and equipment hydraulic oil was replaced with a vegetable oil to mitigate potential pollution as a result of hydraulic line rupture.
