Trapping the wildlife or vice versa - Weipa

Workscope - The Mission River Bridge is located in Weipa in far North Queensland. The job was too reinforce all the piles that support the bridge to ensure the continual supply of bauxite to the refinery. Bauxite is the raw product that is later turned into aluminium. With some tricky angles and long heavy support shells it made for some interesting rigging especially in the low visibility waer. The shells were bolted around and then later filled with grout to give the whole pile some much needed strength. With a great crew of about twenty the work seemed to flow easily and with three divers in the one area it needed too.

Equipment - welding, broco cutting, high pressure water jetting, grit blaster, pneumatic tools, close and general visual inspection

Highlight - With a thin net surrounding the work area you are constantly cleaning out the dead/ly marine life.This is not so much of a highlight but there are times when you get to save one and smile as they swim away. Apart from the sun baking crocodiles and sharks that fill these waters it's the ones that you can't always see. The box jellyfish and irikanji are two of the very dangerous jellyfish that inhabit the waters as well. Giant turtles, shovel nose rays, grouper as big as cows, barramundi and queensfish fill in the watery gaps.
