How to inspect a concrete pontoon
Start by checking the tension wire that secures the pontoon. If the pier shows unusual bending, or if some of the joints have unusually large gaps, this may indicate a wire break. In that case, the tension wire must be replaced. Also check that the grease cups, which protect the wire locks at each end of the pier, are properly in place.
To inspect the condition of the chains, open the covers to the anchor wells. Pay special attention to the area where the chain breaks the water surface, as this is where corrosion often develops fastest. Also consider whether the chains need retightening; this is particularly relevant for new installations, after the sinkers have settled.
Check that the shore attachment and tension reliefs are functioning properly. If the timber fenders show signs of wear or damage, they should be replaced. If you have a outebeam, it is also important to check that the nuts on the rods are properly tightened.
