This article is about the ship repair and construction yard. For other uses, see Shipyard (disambiguation).
A shipyard, also called a dockyard or boatyard, is a place where ships are built and repaired. These can be yachts, military vessels, cruise liners or other cargo or passenger ships. Compared to shipyards, which are sometimes more involved with original construction, dockyards are sometimes more linked with maintenance and basing activities. The terms are routinely used interchangeably, in part because the evolution of dockyards and shipyards has often caused them to change or merge roles.
Shipyards are constructed near the sea or tidal rivers to allow easy access for their ships. The United Kingdom, for example, has shipyards on many of its rivers.
The site of a large shipyard will contain many specialised cranes, dry docks, slipways, dust-free warehouses, painting facilities and extremely large areas for fabrication of the ships. After a ship's useful life is over, it makes its final voyage to a ship-breaking yard, often on a beach in South Asia. Historically ship-breaking was carried out in drydock in developed countries, but high wages and environmental regulations have resulted in movement of the industry to third-world regions.
The oldest structure sometimes identified as a dockyard[a] was built c. 2400 BC by the Indus Valley civilisation in the Harappan port city of Lothal (in present-day Gujarat, India).[2][3] Lothal engineers accorded high priority to the creation of a dockyard and a warehouse to serve the purposes of maritime trade.[4] The name Naupactus, an ancient Greek city on the Gulf of Corinth, means "shipyard" (combination of the Greek words ναύς naus: "ship, boat"; and πήγνυμι pêgnumi, pegnymi: "builder, fixer").[5] Naupactus' reputation in this field extended back into legendary times – the site is traditionally identified by Greek authors such as Ephorus and Strabo as the place where a fleet was said to have been built by the legendary Heraclidae[6] Other early historical shipyards include Tel Abu Saifi, in the Northern Sinai, a 4th-century BCE, Ptolemaic Era, Egyptian dockyard, with two dry docks.[7]Narni was a shipyard of Ancient Rome.
In the Spanish city of Barcelona, the Drassanes shipyards were active from at least the mid-13th century until the 18th century, although at times they served as a barracks for troops as well as an arsenal. During their time of operation the Drassanes were continuously changed, rebuilt and modified, but two original towers and part of the original eight construction-naves remain today. From the 14th century, several hundred years before the Industrial Revolution, ships were the first items to be manufactured in a factory – in the Venice Arsenal of the Venetian Republic in present-day Italy. The Arsenal apparently mass-produced nearly one ship every day using pre-manufactured parts and assembly lines. At its height in the 16th century the enterprise employed 16,000 people. Spain built component ships of the Great Armada of 1588 at ports such as Algeciras or Málaga.[8] In the 17th and 18th centuries, shipyards developed in complexity, with yards such as Blackwall Yard (1614 to 1987), the Scotts Shipbuilding and Engineering Company in Greenock, Scotland (1711–1984) and the Kraljevica Shipyard (1729 and still operating) being established. Havana was long the only dockyard in the Caribbean during the colonial period, the Santísima Trinidad, the largest warship of its time, was built there in 1769. Royal Naval Dockyards in the UK also expanded at this time, (including Woolwich, Deptford, Chatham, Portsmouth and Devonport), Gibraltar, Bombay, Bermuda, Hong Kong and elsewhere worldwide. Similarly, other countries in this period include the Nantes-Indret yard in France (established in 1771 it built ships for the American Revolution including the Deane), Charlestown Navy Yard, later Boston Navy Yard, Boston, Massachusetts (1800 to 1974), the Navy Island, Ontario, Canada (French in the 18th century, then British 1763 to War of 1812), the Philadelphia Naval Shipyard (1799 to 1995), at two locations, and the Portsmouth Naval Shipyard, located on Maine-New Hampshire border (1800 to present, making it the oldest continuously operating shipyard of the US Navy).
New shipyards were established after the war, a prominent example being the Gdańsk Shipyard in 1945, the birthplace of Solidarity Movement – (still a working yard). In the late 20th century, shipbuilding in countries such as the US and UK declined, with yards closing and new shipyards instead expanding in countries such as Japan, South Korea and China.[9][13] By the early 21st century, China became the worlds leading shipbuilder, with approximately 50% of global tonnage build at Chinese shipyards in 2023.[14] Since the early 2020s, shipyard capacity, design and infrastructure is changing in light of technological change and as the result of regulatory changes from the International Maritime Organization requiring ships to be built to operate more efficiently and with less pollution.[15]

Work in shipyards typically involves the construction, modification, retrofitting and repair of ships.[16] This varies according to the type of shipyard and if there are drydocks in the shipyard.[17] It may also involve ship breaking, although in the 21st century, most ship recycling takes place at the Alang Ship Breaking Yard in India, the Chittagong Ship Breaking Yard in Bangladesh and the Gadani Ship Breaking Yard in Pakistan.[18] Shipyards normally have industrial facilities for the production, assembly, and installation of materials. Shipyards normally have quays, jetties and slipways that include specific areas for launching, for repair and for outfitting work.[16] The work in the shipyard will typically involve activities such as the welding and cutting of steel, the use of cutting tools and other machine tools plumbing, electrical work, and the application, removal or renewal of paints and coatings.[19]
Work in the shipyard typically falls under the relevant national domestic health and safety legislation. Examples around the world include the US Shipyard Industry Standards, part of Occupational Safety and Health Administration, the UK workplace regulations of the UK Health and Safety Executive and the Industrial Safety and Health Act of Ministry of Employment and Labor in South Korea.[20][21][22] Work in shipyards can at times be considered dangerous.[23] Accidents in shipyards may involve falls from height,[22] as well as injuries from the use of tools and equipment, and from other hazards such as fire, explosion and pollution.[23] In the late 20th century, many shipyard workers have been affected by the legacy of asbestos use within shipyards, although the use of the material is often prohibited following greater understanding of the effects of asbestosis.[24] Hazards may also come from factors such as slips, trips, excessive-noise, high-pressure tools and impact tools such as needleguns and grinders.[25] To mitigate the dangers and hazards of shipyard work, many employ safe systems of work based on regulation, best practice and guidance, typically involve the control of processes and the use of risk assessments and similar methods of work.[17]
