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.

The Preservation Shipyard is an important part of the museum, where traditional tools and techniques are used to preserve the Museum's collection of historic vessels, including the 1841 whaleship "Charles W. Morgan." A replica of the slave ship "La Amistad" was constructed in the shipyard and launched in 2000. "Amistad" departed from New Haven on June 21, 2007 on a transatlantic voyage to Great Britain, Lisbon, West Africa, and the Caribbean, marking the Atlantic trade and slave route to commemorate the 200th anniversary of the end of slavery in Great Britain.
The 19th-century seafaring village contains nearly all the types of general and specialized trades associated with building and operating a sailing fleet. They include a chandlery, sail loft, ropewalk, cooperage, shipping agent's office, printing office, bank, and others. Also included is The Spouter Tavern, open seasonally and serving "travelers' fare". Each building is used both to show the original activity and to display examples of what was sold or constructed; the nautical instrument shop, for example, displays sextants, nautical timepieces, and so forth, while demonstrations at the cooperage show how casks are assembled.
