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.
Port of Southampton
Warsash is another village in which sailing plays an important role, and also has a history of shipbuilding. In addition it is the home of the Maritime Academy, which provides training for future Merchant Navy Officers. Its famous model ships, used for practising operation of large marine vessels picture were moved in May 2011 from their old base at Marchwood to a new one near Timsbury. The seven ton (tonne) models are powered, and have control systems which simulate the realistic handling of real ships. The new facility for them at Timsbury Lake near Romsey features models of berths, ship canal locks, narrow channels etc. for use in training the next generation of ships' officers.
