A yard in the context of a dockyard or shipyard is a place by the water, often covering a large area, where ships are built, repaired, or maintained. This could include both commercial, military or private vessels. The yard is typically equipped with specialized tools and facilities such as dry docks, slipways, or ship lifts. It employs a variety of skilled craftsmen and professionals including engineers, welders, shipwrights and painters. These yards can sometimes also offer services like refitting, conversion, or even shipbreaking.
