Shipyard
A shipyard (also called a dockyard) is a place where ships are built and repaired. These can be yachts, military vessels, cruise liners or other cargo or passenger ships. Dockyards are sometimes more associated with maintenance and basing activities than shipyards, which are sometimes associated more with initial construction. The terms are routinely used interchangeably, in part because the evolution of dockyards and shipyards has often caused them to change or merge roles.
Shipyard
Having shipyards that have been operational for a long time could lead to serious pollution to the environment as years pass by. There have been many different studies that have shown that welding, sandblasting, paint, and maintenance are some of the many factors that contribute pollution to the environment. Ship hulls are made of steel and have many layers of anti-fouling or anti-corrosion paint to ensure that the metal doesn't corrode and prevent organisms from attaching to the surface. The painting process is inevitable but will it be at nearly every shipyard there is, and two of the most common ways to paint a ship is by airtight spraying and thermal spraying.
