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.
Wrecking yard
A scrapyard is a recycling center that buys and sells scrap metal. Scrapyards are effectively a scrap metal brokerage. Scrap yards typically buy any base metal; for example, iron, steel, stainless steel, brass, copper, aluminum, zinc, nickel, and lead would all be found at a modern-day scrapyard. Scrapyards will often buy electronics, appliances, and metal vehicles. Scrapyards will sell their accumulations of metals either to refineries or larger scrap brokers. Metal theft is committed so thieves can sell stolen copper or other stolen valuable metals to scrapyards.
