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.
United States Shipping Board Merchant Fleet Corporation
On entry into the war there were fewer than 50,000 shipyard workers in U.S. yards and production could not possibly meet wartime demands and attrition. Under the delegated Presidential authority the Shipping Board, through Admiral Capps, General Manager of the Fleet Corporation, requisitioned the shipyards and all steel ships over 2500 deadweight tons then under construction. A primary goal was to focus shipyard work on U.S. requirements rather than commercial needs of neutral and even Allied customers. Another goal was to standardize production. The shipyards protested without success. As many of the 431 ships involved were only contracts or still under construction the EFC assumed responsibility for their completion. There were international consequences, one being the fact that Great Britain had a large number of those ships also planned for war service. In the end the ships were requisitioned and the British were satisfied that they would be used in the war effort.
