PMG have commenced construction of 38 artificial reef modules which are to be installed off the Northern shores of North Stradbroke Island, Brisbane. These artificial reefs are the first of their kind in terms of design and also purpose, the reefs will eventually be installed in clusters where they can be simultaneously used for scuba diving, spearfishing or recreational fishing.
The modules are 5m tall with a 4m x 4m base and weigh approximately 17Te. The reef structures are formed from plastic reinforced concrete, this aids in increasing design life with a reduction of steel reinforcement as well as providing an environmentally friendly solution by having 100% recycled fibres.
The moulds were developed and fabricated in-house by PMG, and a precasting facility has been set up in our waterfront yard in Townsville.
The 1st two modules have now been successfully cast. Only 36 to go!
The modules will be placed into approximately 14m of water off North Stradbroke Island from our barge PMG183W, which is a 54m x 21m dumb barge fitted with a 180Te crawler crane and a 4 point mooring system.
