Shipyard
Many studies have shown that painting is what generates almost half dangerous waste at a shipyard due to using high-pressure equipment to wash or remove any unwanted material that is on it like rust. Which will eventually make its way to the water and creates water pollution to the environment. Once these have compromised the surface of the hull the ship must go to the shipyard for maintenance. In a study in 2011 samples of sediments were collected from two sites in coastal marine area of Yongho Bay, one from the shipyard yard and the other 500m away. These results had analyzed that both samples contained metals that included Al, Fe, Li, V, Cr, Mn, Ni, Cu, Zn, As, Cd, Sn, and Pb. In addition, it had been confirmed that the concentration was higher in the first sample that was by the shipyard then the sample taking 500m away and was due to paint fragments applied to the steel ship hulls.
Cockatoo Island Dockyard
World War I saw an increase in work for the shipyard, which had built over 50 ships and repaired or converted more than 150 by the end of the war. It fitted out transports capable of conveying over 120,000 officers and men and 17,000 horses, and handled nearly 2,000 dockings. Many new facilities were established to accommodate the increased need, including a cruiser wharf, new bolt workshop, brass foundry, ship fitting workshop, coppersmith's workshop, timber store, electrical workshop, tool room and store, electrical workshop, plater's shed, and a new power station and sail loft.
