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.
Rijkswerf (Amsterdam)
The Rijkswerf (Dutch: "State shipyard") in Amsterdam was a Dutch shipyard that build a significant amount of warships for the Royal Netherlands Navy. In 1867 the shipyard was modernized to build armored ships. In 1915 the shipyard ceased to exist. 
The first armored ships the yard constructed were copies of foreign ships purchased by the Dutch navy. Later ships were built to Dutch designs. The yard built among others ironclads, protected cruisers, coastal defense ships, gunboats, monitors and unprotected cruisers.
