Drydock
A dry dock (sometimes drydock or dry-dock) is a narrow basin or vessel that can be flooded to allow a load to be floated in, then drained to allow that load to come to rest on a dry platform. Dry docks are used for the construction, maintenance, and repair of ships, boats, and other watercraft. History Greco-Roman world The Greek author Athenaeus of Naucratis (V 204c-d) reports something that may have been a dry dock in Ptolemaic Egypt in the reign of Ptolemy IV Philopator (221-204 BC) on the occasion of the launch of the enormous ''Tessarakonteres'' rowing ship. It has been calculated that a dock for a vessel of such a size might have had a volume of 750,000 gallons of water. In Roman times, a shipyard at Narni, which is still studied, may have served as a dry dock. Medieval China The use of dry docks in China goes at least as far back the 10th century A.D. In 1088, Song Dynasty scientist and statesman Shen Kuo (1031–1095) wrote in his '' Dream Pool Essays'': Renais ...

HMNB Portsmouth
His Majesty's Naval Base, Portsmouth (HMNB Portsmouth) is one of three operating bases in the United Kingdom for the Royal Navy (the others being HMNB Clyde and HMNB Devonport). Portsmouth Naval Base is part of the city of Portsmouth; it is located on the eastern shore of Portsmouth Harbour, north of the Solent and the Isle of Wight. Until the early 1970s, it was officially known as Portsmouth Royal Dockyard (or HM Dockyard, Portsmouth); thereafter the term 'Naval Base' gained currency, acknowledging a greater focus on personnel and support elements alongside the traditional emphasis on building, repairing and maintaining ships. In 1984 Portsmouth's Royal Dockyard function was downgraded and it was formally renamed the 'Fleet Maintenance and Repair Organisation' (FMRO). The FMRO was privatized in 1998, and for a time (from 2002 to 2014), shipbuilding, in the form of Shipbuilding#Modern shipbuilding manufacturing techniques, block construction, returned.

Song Dynasty
The Song dynasty (; ; 960–1279) was an imperial dynasty of China that began in 960 and lasted until 1279. The dynasty was founded by Emperor Taizu of Song following his usurpation of the throne of the Later Zhou. The Song conquered the rest of the Ten Kingdoms, ending the Five Dynasties and Ten Kingdoms period. The Song often came into conflict with the contemporaneous Liao, Western Xia and Jin dynasties in northern China. After retreating to southern China, the Song was eventually conquered by the Mongol-led Yuan dynasty. The dynasty is divided into two periods: Northern Song and Southern Song. During the Northern Song (; 960–1127), the capital was in the northern city of Bianjing (now Kaifeng) and the dynasty controlled most of what is now Eastern China. The Southern Song (; 1127–1279) refers to the period after the Song lost control of its northern half to the Jurchen-led Jin dynasty in the Jin–Song Wars. At that time, the Song court retreated south of the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
