89-472: Cammell Laird is a British shipbuilding company. It was formed from the merger of Laird Brothers of Birkenhead and Johnson Cammell & Co of Sheffield at the turn of the twentieth century. The company also built railway rolling stock until 1929, when that side of the business was separated and became part of the Metropolitan-Cammell Carriage & Wagon Company . The Laird Company

178-641: A shell corporation in statute, in order to be accountable for any liabilities incurred during its operational history, until it was abolished in 2013 as part of the Government's 2010 public bodies reforms . From March 2013 any remaining liabilities of British Shipbuilders passed to the Department for Business, Innovation and Skills . The assets of the following companies vested in British Shipbuilders on 1 September 1977. Note: Harland and Wolff , Belfast

267-601: A solar barque . Early Egyptians also knew how to fasten the planks of this ship together with mortise and tenon joints. The oldest known tidal dock in the world was built around 2500 BC during the Harappan civilisation at Lothal near the present day Mangrol harbour on the Gujarat coast in India . Other ports were probably at Balakot and Dwarka . However, it is probable that many small-scale ports, and not massive ports, were used for

356-426: A broad beam and heavily curved at both ends. Another important ship type was the galley, which was constructed with both sails and oars. The first extant treatise on shipbuilding was written c.  1436 by Michael of Rhodes, a man who began his career as an oarsman on a Venetian galley in 1401 and worked his way up into officer positions. He wrote and illustrated a book that contains a treatise on shipbuilding,

445-464: A company at the forefront of shipbuilding. The company also built a number of vehicles for the London Underground . An order was placed for 20 trailer cars and 20 control trailer cars in 1919, which were known as 1920 Stock , and were the first tube cars to be built with doors operated by compressed air. They ran with converted French motor cars, originally built in 1906. The doors were fitted with

534-410: A curved, progressive joint could not be achieved. One study finds that there were considerable improvements in ship speed from 1750 to 1850: "we find that average sailing speeds of British ships in moderate to strong winds rose by nearly a third. Driving this steady progress seems to be the continuous evolution of sails and rigging, and improved hulls that allowed a greater area of sail to be set safely in

623-407: A fore and aft sail on the mizzen. Ship-building then saw a steady improvement in design techniques and introduction of new materials. Iron was used for more than fastenings ( nails and bolts ) as structural components such as iron knees were introduced, with examples existing in the mid-18th century and from the mid-19th century onwards. This was partly led by the shortage of "compass timber",

712-474: A further shipyard were also acquired by the corporation, with British Shipbuilders initially comprising 32 shipyards, six marine engine works and 6 general engineering plants. Collectively, British Shipbuilders accounted for 97% of the UK's merchant shipbuilding capacity, 100% of its warship-building capacity, 100% of slow speed diesel engine manufacturing and approximately 50% of ship-repair capacity. Harland & Wolff ,

801-573: A given wind. By contrast, looking at every voyage between the Netherlands and East Indies undertaken by the Dutch East India Company from 1595 to 1795, we find that journey time fell only by 10 percent, with no improvement in the heavy mortality, averaging six percent per voyage, of those aboard." Initially copying wooden construction traditions with a frame over which the hull was fastened, Isambard Kingdom Brunel 's Great Britain of 1843

890-547: A group of 14 ships discovered in Abydos that were constructed of wooden planks which were "sewn" together. Discovered by Egyptologist David O'Connor of New York University , woven straps were found to have been used to lash the planks together, and reeds or grass stuffed between the planks helped to seal the seams. Because the ships are all buried together and near a mortuary belonging to Pharaoh Khasekhemwy , originally they were all thought to have belonged to him, but one of

979-499: A high degree of commercialization and an increase in trade. Large numbers of ships were built to meet the demand. The Ming voyages were large in size, numbering as many as 300 ships and 28,000 men. The shipbuilders were brought from different places in China to the shipyard in Nanjing , including Zhejiang , Jiangxi , Fujian , and Huguang (now the provinces of Hubei and Hunan ). One of

1068-406: A range of sailing rigs that included the crab claw sail . The origins of this technology is difficult to date, relying largely on linguistics (studying the words for parts of boats), the written comments of people from other cultures, including the observations of European explorers at the time of first contact and the later more systematic ethnographic observations of the types of craft in use. There

1157-560: A sample car to a general specification, which were put into service in February 1923, and three of the builders subsequently built production runs. The company supplied 41 motor cars and 40 trailer cars in 1923, 25 control trailers in 1924, and a further 48 motor cars in 1925. In 1927, they built 160 passenger coaches for use in India. To transport them, Cammell Laird asked Watsons of Gainsborough to build five dumb barges. The coaches were loaded onto

1246-514: A sensitive edge, designed to re-open the door if someone became trapped in it, but the mechanism was too sensitive, and was removed after an initial trial period. The cars continued in operation until 1938, eight years after the motor cars were withdrawn, but following withdrawal, five cars became a mobile training school. Cammell Laird also built a number of Standard Stock vehicles for the Underground. They were one of five builders approached to build

1335-796: A significant number of workers, and generate income as the shipbuilding market is global . British Shipbuilders British Shipbuilders (BS) was a public corporation that owned and managed the shipbuilding industry in Great Britain from 1977 through the 1980s. Its head office was at Benton House in Newcastle upon Tyne , England. The corporation was founded as a result of the Aircraft and Shipbuilding Industries Act 1977 , which nationalised 27 major shipbuilding and marine engineering companies in Great Britain. A further six ship repair companies and

1424-863: A similar design. Austronesians established the Austronesian maritime trade network at around 1000 to 600 BC, linking Southeast Asia with East Asia, South Asia, the Middle East, and later East Africa. The route later became part of the Spice trade network and the Maritime Silk Road . The naval history of China stems back to the Spring and Autumn period (722 BC–481 BC) of the ancient Chinese Zhou dynasty . The Chinese built large rectangular barges known as "castle ships", which were essentially floating fortresses complete with multiple decks with guarded ramparts . However,

1513-411: A single piece of hollowed-out log. At the sides were two planks, and two horseshoe-shaped wood pieces formed the prow and stern . These were fitted tightly together edge-to-edge with dowels inserted into holes in between, and then lashed to each other with ropes (made from rattan or fiber) wrapped around protruding lugs on the planks. This characteristic and ancient Austronesian boatbuilding practice

1602-518: A treatise on mathematics, much material on astrology, and other materials. His treatise on shipbuilding treats three kinds of galleys and two kinds of round ships. Shipbuilders in the Ming dynasty (1368~1644) were not the same as the shipbuilders in other Chinese dynasties, due to hundreds of years of accumulated experiences and rapid changes in the Ming dynasty. Shipbuilders in the Ming dynasty primarily worked for

1691-610: A year later. In October 2018 it was announced that the yard had won 'Lot 3' of an MOD contract to maintain the four new Tide class of tankers for the RFA in a deal worth an estimated £262m. A new contract worth £357m was also announced that would see Cammell Laird continue to maintain the five RFA ships it currently supports. The yard was named as part of a consortium to build the Royal Navy's new Type 26 Frigate in September 2023. BAE System are

1780-467: Is a famous example). Later Great Britain ' s iron hull was sheathed in wood to enable it to carry a copper-based sheathing . Brunel's Great Eastern represented the next great development in shipbuilding. Built-in association with John Scott Russell , it used longitudinal stringers for strength, inner and outer hulls, and bulkheads to form multiple watertight compartments. Steel also supplanted wrought iron when it became readily available in

1869-654: Is a possibility that they may have reached the Americas . After the 11th century, a new type of ship called djong or jong was recorded in Java and Bali. This type of ship was built using wooden dowels and treenails, unlike the kunlun bo which used vegetal fibres for lashings. The empire of Majapahit used jong, built in northern Java, for transporting troops overseas. The jongs were transport ships which could carry 100–2000 tons of cargo and 50–1000 people, 28.99–88.56 meter in length. The exact number of jong fielded by Majapahit

1958-408: Is a similar activity called boat building . The dismantling of ships is called ship breaking . The earliest evidence of maritime transport by modern humans is the settlement of Australia between 50,000 and 60,000 years ago. This almost certainly involved rafts , possibly equipped with some sort of sail . Much of the development beyond that raft technology occurred in the "nursery" areas of

2047-494: Is called Cammell Laird Social Club . See: List of ships built by Cammell Laird 53°23′6.85″N 3°0′45.01″W  /  53.3852361°N 3.0125028°W  / 53.3852361; -3.0125028 Shipbuilding Until recently, with the development of complex non-maritime technologies, a ship has often represented the most advanced structure that the society building it could produce. Some key industrial advances were developed to support shipbuilding, for instance

2136-600: Is known as the " lashed-lug " technique. They were commonly caulked with pastes made from various plants as well as tapa bark and fibres which would expand when wet, further tightening joints and making the hull watertight. They formed the shell of the boat, which was then reinforced by horizontal ribs. Shipwrecks of Austronesian ships can be identified from this construction as well as the absence of metal nails. Austronesian ships traditionally had no central rudders but were instead steered using an oar on one side. Austronesians traditionally made their sails from woven mats of

2225-571: Is noted in the works of Ibn Jubayr . The ships of Ancient Egypt's Eighteenth Dynasty were typically about 25 meters (80 ft) in length and had a single mast , sometimes consisting of two poles lashed together at the top making an "A" shape. They mounted a single square sail on a yard , with an additional spar along the bottom of the sail. These ships could also be oar propelled. The ocean- and sea-going ships of Ancient Egypt were constructed with cedar wood, most likely hailing from Lebanon. The ships of Phoenicia seem to have been of

2314-499: Is only a small body of archaeological evidence available. Since Island Southeast Asia contained effective maritime transport between its very large number of islands long before Austronesian seafaring, it is argued that Austronesians adopted an existing maritime technology from the existing inhabitants of this region. Austronesian ships varied from simple canoes to large multihull ships. The simplest form of all ancestral Austronesian boats had five parts. The bottom part consists of

2403-411: Is unknown, but the largest number of jong deployed in an expedition is about 400 jongs, when Majapahit attacked Pasai, in 1350. Until recently, Viking longships were seen as marking an advance on traditional clinker -built hulls where leather thongs were used to join plank boards. This consensus has recently been challenged. Haywood has argued that earlier Frankish and Anglo-Saxon nautical practice

2492-571: The ghe mành . Early Egyptians also knew how to assemble planks of wood with treenails to fasten them together, using pitch for caulking the seams. The " Khufu ship ", a 43.6-meter vessel sealed into a pit in the Giza pyramid complex at the foot of the Great Pyramid of Giza in the Fourth Dynasty around 2500 BC, is a full-size surviving example which may have fulfilled the symbolic function of

2581-579: The k'un-lun po or kunlun bo ("ship of the k'un-lun [dark-skinned southern people]"). These ships used two types of sail of their invention, the junk sail and tanja sail . Large ships are about 50–60 metres (164–197 ft) long, had 5.2–7.8 metres (17–26 ft) tall freeboard , each carrying provisions enough for a year, and could carry 200–1000 people. The Chinese recorded that these Southeast Asian ships were hired for passage to South Asia by Chinese Buddhist pilgrims and travelers, because they did not build seaworthy ships of their own until around

2670-702: The Abbasid period. Mughal Empire had a large shipbuilding industry, which was largely centred in the Bengal Subah . Economic historian Indrajit Ray estimates shipbuilding output of Bengal during the sixteenth and seventeenth centuries at 223,250 tons annually, compared with 23,061 tons produced in nineteen colonies in North America from 1769 to 1771. He also assesses ship repairing as very advanced in Bengal. Documents from 1506, for example, refer to watercraft on

2759-625: The Birkenhead , Teesside and Tyneside shipyards owned by Cammell Laird shiprepair were acquired by the A&;P Shiprepair Group in 2001. Cammell Laird Gibraltar, the Royal Dockyard facility in Gibraltar , was disposed of through a local management buyout . A&P Group sold its Birkenhead subsidiary (A&P Birkenhead) to Northwestern Shiprepairers & Shipbuilders in 2005. Peel Holdings , owners of

2848-533: The Mediterranean and in Maritime Southeast Asia . Favoured by warmer waters and a number of inter-visible islands, boats (and, later, ships) with water-tight hulls (unlike the "flow through" structure of a raft) could be developed. The ships of ancient Egypt were built by joining the hull planks together, edge to edge, with tenons set in mortices cut in the mating edges. A similar technique, but with

2937-596: The Mersey Docks and Harbour Company and 50% owners of Northwestern Shiprepairers & Shipbuilders, purchased the Cammell Laird shipyard site and surrounding land in January 2007, to facilitate the proposed Wirral Waters development, although Northwestern Shiprepairers & Shipbuilders continue to maintain a long-term lease on the shipyard facilities, which will form an integral part of the regeneration scheme. In 2007, it

3026-533: The Napoleonic Wars were still built more or less to the same basic plan as those of the Spanish Armada of two centuries earlier, although there had been numerous subtle improvements in ship design and construction throughout this period. For instance, the introduction of tumblehome , adjustments to the shapes of sails and hulls, the introduction of the wheel, the introduction of hardened copper fastenings below

3115-463: The Persian Gulf . Evidence from Ancient Egypt shows that the early Egyptians knew how to assemble planks of wood into a ship hull as early as 3100 BC. Egyptian pottery as old as 4000 BC shows designs of early fluvial boats or other means for navigation. The Archaeological Institute of America reports that some of the oldest ships yet unearthed are known as the Abydos boats . These are

3204-453: The Sierra Leone river carrying 120 men. Others refer to Guinea coast peoples using war canoes of varying sizes – some 70 feet in length, 7–8 feet broad, with sharp pointed ends, rowing benches on the side, and quarterdecks or forecastles build of reeds. The watercraft included miscellaneous facilities, such as cooking hearths, and storage spaces for the crew's sleeping mats. From

3293-461: The 14 ships dates to 3000 BC, and the associated pottery jars buried with the vessels also suggest earlier dating. The ship dating to 3000 BC was about 75 feet (23 m) long and is now thought to perhaps have belonged to an earlier pharaoh. According to professor O'Connor, the 5,000-year-old ship may have even belonged to Pharaoh Aha . The Austronesian expansion , which began c.  3000 BC with migration from Taiwan to

3382-536: The 17th century, some kingdoms added brass or iron cannons to their vessels. By the 18th century, however, the use of swivel cannons on war canoes accelerated. The city-state of Lagos , for instance, deployed war canoes armed with swivel cannons. With the development of the carrack , the west moved into a new era of ship construction by building the first regular oceangoing vessels. In a relatively short time, these ships grew to an unprecedented size, complexity, and cost. Shipyards became large industrial complexes, and

3471-590: The 8–9th century AD. Austronesians (especially from western Island Southeast Asia ) were trading in the Indian Ocean as far as Africa during this period. By around 50 to 500 AD, a group of Austronesians, believed to be from the southeastern coasts of Borneo (possibly a mixed group related to the modern Ma'anyan , Banjar , and/or the Dayak people ) crossed the Indian Ocean and colonized Madagascar . This resulted in

3560-731: The Admiral Zheng He . Six voyages were conducted under the Yongle Emperor's reign, the last of which returned to China in 1422. After the Yongle Emperor's death in 1424, his successor the Hongxi Emperor ordered the suspension of the voyages. The seventh and final voyage began in 1430, sent by the Xuande Emperor . Although the Hongxi and Xuande Emperors did not emphasize sailing as much as the Yongle Emperor, they were not against it. This led to

3649-609: The Cammell Laird slipways into the River Mersey . Among the many famous ships made by the companies were the world's first steel ship, the Ma Roberts , built in 1858 for Dr. Livingstone's Zambezi expedition, CSS  Alabama that was built in 1862 for the Confederate States of America , HMS  Caroline that holds the record fastest build time of any significant warship (nine months from her keel being laid till her launch),

3738-499: The Chinese vessels during this era were essentially fluvial (riverine). True ocean-going Chinese fleets did not appear until the 10th century Song dynasty . There is considerable knowledge regarding shipbuilding and seafaring in the ancient Mediterranean. Large multi-masted seafaring ships of Southeast Asian Austronesians first started appearing in Chinese records during the Han dynasty as

3827-648: The Chinese, from the Old Javanese parahu , Javanese prau , or Malay perahu – large ship. Southern Chinese junks showed characteristics of Austronesian ships that they are made using timbers of tropical origin, with keeled, V-shaped hull. This is different from northern Chinese junks, which are developed from flat-bottomed riverine boats. The northern Chinese junks were primarily built of pine or fir wood, had flat bottoms with no keel, water-tight bulkheads with no frames, transom (squared) stern and stem, and have their planks fastened with iron nails or clamps. It

3916-561: The Han dynasty junk ship design in the same century. The Chinese were using square sails during the Han dynasty and adopted the Austronesian junk sail later in the 12th century. Iconographic remains show that Chinese ships before the 12th century used square sails, and the junk rig of Chinese ships is believed to be developed from tilted sails . Southern Chinese junks were based on keeled and multi-planked Austronesian ship known as po by

4005-695: The Harappan maritime trade. Ships from the harbour at these ancient port cities established trade with Mesopotamia . Shipbuilding and boatmaking may have been prosperous industries in ancient India. Native labourers may have manufactured the flotilla of boats used by Alexander the Great to navigate across the Hydaspes and even the Indus , under Nearchos . The Indians also exported teak for shipbuilding to ancient Persia . Other references to Indian timber used for shipbuilding

4094-561: The Second Anglo-Boer War. The armoured road train was the first self-propelled, free-roaming, armoured military land vehicle ever built, predating the tanks of World War One by nearly two decades. The company was nationalised along with the rest of the British shipbuilding industry as British Shipbuilders in 1977. The yard was subject to a labour dispute in 1984 triggered by the yard making nearly 1,000 redundancies. This led to some of

4183-484: The United States in a 15-year period just before the war was a grand total of two. During the war, thousands of Liberty ships and Victory ships were built, many of them in shipyards that did not exist before the war. And, they were built by a workforce consisting largely of women and other inexperienced workers who had never seen a ship before (or even the ocean). After World War II , shipbuilding (which encompasses

They were taken to Hull for export. In 1929, the railway rolling stock business of Cammell Laird was spun off and merged to become Metropolitan-Cammell Carriage & Wagon Company . Between 1829 and 1947, over 1,100 vessels of all kinds were launched from

4450-516: The bottom planking of cogs . The north-European and Mediterranean traditions merged in the late 15th century, with carvel construction being adopted in the North and the centre-line mounted rudder replacing the quarter rudder of the Mediterranean. These changes broadly coincided with improvements in sailing rigs, with the three masted ship becoming common, with square sails on the fore and main masts, and

4539-495: The business by his three sons, renaming the company John Laird, Sons & Co. The sons continued the business after their father's death in 1874 as Laird Brothers. Johnson Cammell & Co. was founded by Charles Cammell and Henry and Thomas Johnson: it made, amongst many other metal products, iron wheels and rails for Britain's railways and was based in Sheffield . In 1903 the businesses of Messrs. Cammell and Laird merged to create

4628-518: The end of 1982, British Shipbuilders had closed half of its shipyards in an effort to reduce over-capacity. The terms of the British Shipbuilders Act 1983 then required the company to begin a process of privatising its remaining assets. The various divisions that had remained under integrated nationalised ownership were divested throughout the 1980s as the company wound up operations. The profitable warship-builders were sold off initially, with

4717-561: The end of the Upholder -class submarine building programme in 1993, the owners of Cammell Laird, VSE, announced the yard's closure. This was strongly opposed by the workforce through trade union campaigners including the GMB, led by communist firebrand official Barry Williams . Part of the shipyard site was leased by the Coastline Group as a ship repair facility. Coastline eventually bought part of

4806-495: The end of the Ming dynasty in 1644. During this period, Chinese navigation technology did not make any progress and even declined in some aspect. In the Islamic world, shipbuilding thrived at Basra and Alexandria . The dhow , felucca , baghlah , and the sambuk became symbols of successful maritime trade around the Indian Ocean from the ports of East Africa to Southeast Asia and the ports of Sindh and Hind (India) during

In 1898, Cammell provided the half-inch armour plate used to fabricate the four Fowler Armoured Road Trains built during

4984-575: The government, under command of the Ministry of Public Works . During the early years of the Ming dynasty, the Ming government maintained an open policy towards sailing. Between 1405 and 1433, the government conducted seven diplomatic Ming treasure voyages to over thirty countries in Southeast Asia, India, the Middle East and Eastern Africa. The voyages were initiated by the Yongle Emperor , and led by

5073-507: The infrastructure required to transport the trees from their point of origin to the shipyards. Shipbuilders were usually divided into different groups and had separate jobs. Some were responsible for fixing old ships; some were responsible for making the keel and some were responsible for building the helm. After 1477, the Ming government reversed its open maritime policies, enacting a series of isolationist policies in response to piracy . The policies, called Haijin (sea ban), lasted until

5162-524: The introduction of outrigger canoe technology to non-Austronesian cultures in the East African coast. The ancient Chinese also built fluvial ramming vessels as in the Greco-Roman tradition of the trireme , although oar-steered ships in China lost favor very early on since it was in the 1st century China that the stern -mounted rudder was first developed. This was dually met with the introduction of

Then, between 1500 BC and 1500 AD they settled uninhabited islands of the Pacific, and also sailed westward to Madagascar. This is associated with distinctive maritime technology: lashed lug construction techniques (both in outrigger canoes and in large planked sailing vessels), various types of outrigger and twin-hulled canoes and

5340-485: The keel, the hull was made by overlapping nine strakes on either side with rivets fastening the oaken planks together. It could hold upwards of thirty men. Sometime around the 12th century, northern European ships began to be built with a straight sternpost , enabling the mounting of a rudder, which was much more durable than a steering oar held over the side. Development in the Middle Ages favored "round ships", with

5429-470: The latter half of the 19th century, providing great savings when compared with iron in cost and weight. Wood continued to be favored for the decks. During World War II , the need for cargo ships was so great that construction time for Liberty ships went from initially eight months or longer, down to weeks or even days. They employed production line and prefabrication techniques such as those used in shipyards today. The total number of dry-cargo ships built in

British Shipbuilders finally ceased active shipbuilding operations in 1989, with the closure of its last shipyards: North East Shipbuilders Ltd.'s Pallion and Southwick Shipyards at Sunderland . The remaining assets of North East Shipbuilders Ltd. were then privatised. British Shipbuilders continued to exist as

5607-555: The most famous shipyards was Long Jiang Shipyard ( zh:龙江船厂 ), located in Nanjing near the Treasure Shipyard where the ocean-going ships were built. The shipbuilders could build 24 models of ships of varying sizes. Several types of ships were built for the voyages, including Shachuan (沙船), Fuchuan (福船) and Baochuan ( treasure ship ) (宝船). Zheng He's treasure ships were regarded as Shachuan types, mainly because they were made in

5696-538: The naturally curved timber that meant that shapes could be cut without weaknesses caused by cuts across the grain of the timber. Ultimately, whole ships were made of iron and, later, steel . The earliest known depictions (including paintings and models) of shallow-water sailing boats is from the 6th to 5th millennium BC of the Ubaid period of Mesopotamia . They were made from bundled reeds coated in bitumen and had bipod masts. They sailed in shallow coastal waters of

5785-422: The only shipbuilder based in Northern Ireland was deemed to be a special political case and remained out of the control of the British Shipbuilders' management, despite it also being in state ownership from 1977. The same act nationalised the three large UK aerospace companies and grouped them in an analogous corporation, British Aerospace . The first Chairman of British Shipbuilders, serving from 1977 to 1980,

The ancient Champa of Vietnam also uniquely developed basket-hulled boats whose hulls were composed of woven and resin - caulked bamboo, either entirely or in conjunction with plank strakes . They range from small coracles (the o thúng ) to large ocean-going trading ships like

6052-477: The sawing of timbers by mechanical saws propelled by windmills in Dutch shipyards during the first half of the 17th century. The design process saw the early adoption of the logarithm (invented in 1615) to generate the curves used to produce the shape of a hull , especially when scaling up these curves accurately in the mould loft . Shipbuilding and ship repairs, both commercial and military, are referred to as naval engineering . The construction of boats

6141-450: The shipbuilder learned the techniques of shipbuilding from his family and is very likely to earn a higher status in the shipyard. Additionally, the shipbuilder had access to business networking that could help to find clients. If a shipbuilder entered the occupation through an apprenticeship, the shipbuilder was likely a farmer before he was hired as a shipbuilder, or he was previously an experienced shipbuilder. Many shipbuilders working in

These considerations led to the documentation of design and construction practices in what had previously been a secretive trade run by master shipwrights and ultimately led to the field of naval architecture , in which professional designers and draftsmen played an increasingly important role. Even so, construction techniques changed only very gradually. The ships of

6408-422: The shipyard were forced into the occupation. The ships built for Zheng He's voyages needed to be waterproof, solid, safe, and have ample room to carry large amounts of trading goods. Therefore, due to the highly commercialized society that was being encouraged by the expeditions, trades, and government policies, the shipbuilders needed to acquire the skills to build ships that fulfil these requirements. Shipbuilding

6497-433: The shipyards, the marine equipment manufacturers, and many related service and knowledge providers) grew as an important and strategic industry in a number of countries around the world. This importance stems from: Historically, the industry has suffered from the absence of global rules and a tendency towards ( state - supported ) over-investment due to the fact that shipyards offer a wide range of technologies, employ

6586-649: The site of Portus in Rome revealed inscriptions in a shipyard constructed during the reign of Trajan (98–117) that indicated the existence of a shipbuilders guild . Roughly at this time is the last migration wave of the Austronesian expansion , when the Polynesian islands spread over vast distances across the Pacific Ocean were being colonized by the (Austronesian) Polynesians from Island Melanesia using double-hulled voyaging catamarans . At its furthest extent, there

6675-478: The stronger flushed deck design derived from Indian designs, and the increasing use of iron reinforcement. The flushed deck originated from the Bengal rice ships, with Bengal being famous for its shipbuilding industry at the time. Iron was gradually adopted in ship construction, initially to provide stronger joints in a wooden hull e.g. as deck knees, hanging knees, knee riders and the other sharp joints, ones in which

6764-430: The tenons being pinned in position by dowels, was used in the Mediterranean for most of classical antiquity . Both these variants are "shell first" techniques, where any reinforcing frames are inserted after assembly of the planking has defined the hull shape. Carvel construction then took over in the Mediterranean. Northern Europe used clinker construction , but with some flush-planked ship-building in, for instance,

6853-549: The treasure shipyard in Nanjing. Shachuan , or 'sand-ships', are ships used primarily for inland transport. However, in recent years, some researchers agree that the treasure ships were more of the Fuchuan type. It is said in vol. 176 of San Guo Bei Meng Hui Bian (三朝北盟汇编) that ships made in Fujian are the best ones. Therefore, the best shipbuilders and laborers were brought from these places to support Zheng He's expedition. The shipyard

6942-603: The waterline, the introduction of copper sheathing as a deterrent to shipworm and fouling, etc. In the early decades of the Industrial Revolution (1760 to 1825) western ship design remained largely based on its traditional pre-industrial designs and materials and yet greatly improved in safety as "the risk of being wrecked for Atlantic shipping fell by one-third, and of foundering by two thirds, reflecting improvements in seaworthiness and navigation respectively." The improvement in seaworthiness has been credited to adopting

7031-441: The workers occupying a partially built gas rig, AV-1 . 37 workers were later arrested, jailed and sacked for their roles in the protest. In 1986, it returned to the private sector as part of Barrow-in-Furness -based Vickers Shipbuilding & Engineering (VSE). VSE and Cammell Laird were the only British shipyards capable of producing nuclear submarines. In 1993, it completed HMS Unicorn (S43) – now HMCS  Windsor . After

7120-529: Was Admiral Sir Anthony Griffin . He was succeeded by Sir Robert Atkinson , who in turn was succeeded by Graham Day in 1984, Phillip Hares in 1986. The final operational chairman, John Lister, took office in 1987, continuing until 1989. The company was initially organised into four operating divisions: Merchant, Naval, Ship-repair, Marine Engineering and General Engineering. This was restructured into five trading divisions in 1980: Merchant Shipbuilding, Warship-building, Engineering, Ship-repair and Offshore. By

7209-399: Was announced in October 2017 that Cammell Laird had struck a 'teaming agreement' with BAE Systems to bid for Ministry of Defence contracts to build the Royal Navy's Type 31e frigates . In 2018, Red Funnel chose the shipyard to construct a £10m cargo ferry, MV  Red Kestrel . Construction of the ferry began with a formal keel laying ceremony on 31 May and the vessel entered service

7298-471: Was announced that the company had won a £28m Ministry of Defence contract to overhaul the Royal Fleet Auxiliary ship RFA  Fort Rosalie . In January 2010, it was announced that Lairds had received a £44m order for the flight decks of the Royal Navy's new aircraft carrier HMS  Queen Elizabeth . In May 2012, it was announced that complete shipbuilding was set to return to the yard with

7387-515: Was announced that the occupiers of Cammell Laird Dock , Northwestern Shiprepairers & Shipbuilders, had acquired the rights to the Cammell Laird name. On 17 November 2008, Northwestern Shiprepairers & Shipbuilders officially renamed itself Cammell Laird Shiprepairers & Shipbuilders Limited, stating that recent economic success had made the time right, and that "Cammell Laird is an internationally recognised brand which carries tremendous goodwill when bidding for contracts." In February 2008, it

7476-472: Was founded by William Laird , who had established the Birkenhead Iron Works in 1824. When he was joined by his son, John Laird in 1828, their first ship was an iron barge. John realised that the techniques of making boilers could be applied to making ships. The company soon became pre-eminent in the manufacture of iron ships and also made major advances in propulsion. In 1860, John Laird was joined in

7565-525: Was much more accomplished than had been thought and has described the distribution of clinker vs. carvel construction in Western Europe (see map [1] ). An insight into shipbuilding in the North Sea/Baltic areas of the early medieval period was found at Sutton Hoo , England, where a ship was buried with a chieftain. The ship was 26 metres (85 ft) long and 4.3 metres (14 ft) wide. Upward from

7654-539: Was not the sole industry utilising Chinese lumber at that time; the new capital was being built in Beijing from approximately 1407 onwards, which required huge amounts of high-quality wood. These two ambitious projects commissioned by Emperor Yongle would have had enormous environmental and economic effects, even if the ships were half the dimensions given in the History of Ming . Considerable pressure would also have been placed on

7743-444: Was the first radical new design, being built entirely of wrought iron. Despite her success, and the great savings in cost and space provided by the iron hull, compared to a copper-sheathed counterpart, there remained problems with fouling due to the adherence of weeds and barnacles. As a result, composite construction remained the dominant approach where fast ships were required, with wooden timbers laid over an iron frame ( Cutty Sark

7832-426: Was under the command of Ministry of Public Works . The shipbuilders had no control over their lives. The builders, commoner's doctors, cooks and errands had lowest social status. The shipbuilders were forced to move away from their hometown to the shipyards. There were two major ways to enter the shipbuilder occupation: family tradition, or apprenticeship. If a shipbuilder entered the occupation due to family tradition,

7921-414: Was unknown when the Chinese people started adopting Southeast Asian (Austronesian) shipbuilding techniques. They may have been started as early as the 8th century, but the development was gradual and the true ocean-going Chinese junks did not appear suddenly. The word "po" survived in Chinese long after, referring to the large ocean-going junks. In September 2011, archeological investigations done at
