Ashipyard, also called adockyard orboatyard, is a place whereships arebuilt and repaired. These can beyachts, 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 theevolution 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. TheUnited Kingdom, for example, has shipyards on many of its rivers.
The site of a large shipyard will contain many specialisedcranes,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 aship-breaking yard, often on abeach inSouth 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 builtc. 2400 BC by theIndus Valley civilisation in theHarappan port city ofLothal (in present-dayGujarat, India).[2][3] Lothal engineers accorded high priority to the creation of a dockyard and awarehouse to serve the purposes of maritime trade. The nameNaupactus, an ancient Greek city on the Gulf of Corinth, means "shipyard" (combination of theGreek words ναύςnaus: "ship, boat"; and πήγνυμιpêgnumi,pegnymi: "builder, fixer").[4] Naupactus' reputation in this field extended back into legendary times – the site is traditionally identified by Greek authors such asEphorus andStrabo as the place where a fleet was said to have been built by the legendaryHeraclidae[5] Other early historical shipyards includeTel Abu Saifi, in the NorthernSinai, a 4th-century BCE, Ptolemaic Era, Egyptian dockyard, with two dry docks.[6]Narni was a shipyard ofAncient Rome.
In the Spanish city ofBarcelona, theDrassanes 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 theIndustrial Revolution, ships were the first items to be manufactured in afactory – in theVenice Arsenal of theVenetian Republic in present-dayItaly. The Arsenal apparentlymass-produced nearly one ship every day usingpre-manufactured parts andassembly lines. At its height in the 16th century the enterprise employed 16,000 people. Spain built component ships of theGreat Armada of 1588 at ports such asAlgeciras orMálaga.[7] In the 17th and 18th centuries, shipyards developed in complexity, with yards such asBlackwall Yard (1614 to 1987), theScotts Shipbuilding and Engineering Company in Greenock, Scotland (1711–1984) and theKraljevica Shipyard (1729 and still operating) being established.Havana was long the only dockyard in theCaribbean during the colonial period, theSantísima Trinidad, the largest warship of its time, was built there in 1769.Royal Naval Dockyards in theUK also expanded at this time, (includingWoolwich,Deptford,Chatham,Portsmouth andDevonport),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 theDeane), Charlestown Navy Yard, laterBoston Navy Yard,Boston,Massachusetts (1800 to 1974), theNavy Island,Ontario, Canada (French in the 18th century, then British 1763 toWar of 1812), thePhiladelphia Naval Shipyard (1799 to 1995), at two locations, and thePortsmouth Naval Shipyard, located onMaine-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 theGdańsk Shipyard in 1945, the birthplace ofSolidarity 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 asJapan,South Korea andChina.[8][12] By the early 21st century, China became the worlds leading shipbuilder, with approximately 50% of global tonnage build at Chinese shipyards in 2023.[13] Since the early 2020s, shipyard capacity, design and infrastructure is changing in light of technological change and as the result of regulatory changes from theInternational Maritime Organization requiring ships to be built to operate more efficiently and with less pollution.[14]

Work in shipyards typically involves the construction, modification, retrofitting and repair of ships.[15] This varies according to the type of shipyard and if there aredrydocks in the shipyard.[16] It may also involveship breaking, although in the 21st century, most ship recycling takes place at theAlang Ship Breaking Yard inIndia, theChittagong Ship Breaking Yard inBangladesh and theGadani Ship Breaking Yard inPakistan.[17] 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.[15] The work in the shipyard will typically involve activities such as thewelding and cutting ofsteel, the use ofcutting tools and othermachine tools plumbing, electrical work, and the application, removal or renewal of paints and coatings.[18]
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 ofOccupational Safety and Health Administration, the UK workplace regulations of the UKHealth and Safety Executive and the Industrial Safety and Health Act of Ministry of Employment and Labor in South Korea.[19][20][21] Work in shipyards can at times be considered dangerous.[22] Accidents in shipyards may involve falls from height,[21] as well as injuries from the use of tools and equipment, and from other hazards such as fire, explosion and pollution.[22] In the late 20th century, many shipyard workers have been affected by the legacy ofasbestos use within shipyards, although the use of the material is often prohibited following greater understanding of the effects ofasbestosis.[23] Hazards may also come from factors such as slips, trips, excessive-noise, high-pressure tools and impact tools such asneedleguns andgrinders.[24] 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.[16]
