Shipyards and dockyards are places where ships are repaired and built. 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.
Countries with large shipbuilding industries include Singapore, South Korea, Australia, Japan, China, Germany, Turkey, Poland and Croatia. The shipbuilding industry tends to be more fragmented in Europe than in Asia. In European countries there are a greater number of small companies, compared to the fewer, larger companies in the shipbuilding countries of Asia.
Most shipbuilders in the United States are privately owned, the largest being Huntington Ingalls Industries, a multi-billion dollar defense contractor. The publicly owned shipyards in the US are Naval facilities providing basing, support and repair.
Shipyards are constructed nearby the sea or tidal rivers to allow easy access for their ships. In the United Kingdom, for example, shipyards were established on the River Thames (King Henry VIII founded yards at Woolwich and Deptford in 1512 and 1513 respectively), River Mersey, River Tees, River Tyne, River Wear and River Clyde – the latter growing to be the World's pre-eminent shipbuilding centre.
Sir Alfred Yarrow established his yard by the Thames in London's Docklands in the late 19th century before moving it northwards to the banks of the Clyde at Scotstoun (1906–08). Other famous UK shipyards include the Harland and Wolff yard in Belfast, Northern Ireland, where the Titanic was built, and the naval dockyard at Chatham, England on the Medway in north Kent.
After a ship's useful life is over, it makes its final voyage to a shipbreaking yard, often on a beach in South Asia. Historically shipbreaking was carried on in drydock in developed countries, but high wages and environmental regulations have resulted in movement of the industry to developing regions.
The world's earliest known dockyards were built in the Harappan port city of Lothal circa 2400 BC in Gujarat, India. Lothal's dockyards connected to an ancient course of the Sabarmati river on the trade route between Harappan cities in Sindh and the peninsula of Saurashtra when the surrounding Kutch desert was a part of the Arabian Sea.
Lothal engineers accorded high priority to the creation of a dockyard and a warehouse to serve the purposes of naval trade. The dock was built on the eastern flank of the town, and is regarded by archaeologists as an engineering feat of the highest order. It was located away from the main current of the river to avoid silting, but provided access to ships in high tide as well.
The name of the ancient Greek city of Naupactus means "shipyard" (combination of the Greek words ναύς naus ship, boat and πήγνυμι pêgnumi, pegnymi builder, fixer). Naupactus' reputation in this field extends to the time of legend, where it is depicted as the place where the Heraclidae built a fleet to invade the Peloponnesus.
In the Spanish city of Barcelona, the Drassanes shipyards were active from at least the mid-13th century until the 18th century, although it at times served as a barracks for troops as well as an arsenal. During its time of operation it was continuously changed, rebuilt and modified, but two original towers and part of the original eight construction naves remain today. It is currently a maritime museum.
Ships were the first items to be manufactured in a factory, several hundred years before the Industrial Revolution, in the Venice Arsenal, Venice, Italy. The Arsenal apparently mass-produced nearly one ship every day using pre-manufactured parts, and assembly lines and, at its height, employed 16,000 people.
