Rajabagan Dock (RBD) is a shipyard situated on the left bank of the Hooghly River about three nautical miles down stream of Calcutta Dock System. [1] The shipyard is mainly engaged in shipbuilding and repair of small and medium sized inland water transport and coastal vessels.
Rajabagan Dock have a long history of existence. In 1967 it came into control of Central Inland Water Transport Corporation (CIWTC). However due to heavy losses it came under management of Garden Reach Shipbuilders & Engineers (GRSE) on 1 July 2006.
As of 2006, RBD Unit is spread over 33 acres of land with 550 M open river front at Rajabagan. The unit is capable of pre-Launch activities of 03 ships of size 50M and post launch outfitting of 04 ships at open river. The yard has three jetties and also has three dry docks.
Dry Docks:
The Aire and Calder Navigation is the canalised section of the Rivers Aire and Calder in West Yorkshire, England. The first improvements to the rivers above Knottingley were completed in 1704 when the Aire was made navigable to Leeds and the Calder to Wakefield, by the construction of 16 locks. Lock sizes were increased several times, as was the depth of water, to enable larger boats to use the system. The Aire below Haddlesey was bypassed by the opening of the Selby Canal in 1778. A canal from Knottingley to the new docks and new town at Goole provided a much shorter route to the River Ouse from 1826. The New Junction Canal was constructed in 1905, to link the system to the River Don Navigation, by then part of the Sheffield and South Yorkshire Navigation.
A ship canal is a canal especially intended to accommodate ships used on the oceans, seas, or lakes to which it is connected.
A 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.
Intermodal freight transport involves the transportation of freight in an intermodal container or vehicle, using multiple modes of transportation, without any handling of the freight itself when changing modes. The method reduces cargo handling, and so improves security, reduces damage and loss, and allows freight to be transported faster. Reduced costs over road trucking is the key benefit for inter-continental use. This may be offset by reduced timings for road transport over shorter distances.
Panamax and New Panamax are terms for the size limits for ships travelling through the Panama Canal. The limits and requirements are published by the Panama Canal Authority (ACP) in a publication titled "Vessel Requirements". These requirements also describe topics like exceptional dry seasonal limits, propulsion, communications, and detailed ship design.
A cargo ship or freighter is a merchant ship that carries cargo, goods, and materials from one port to another. Thousands of cargo carriers ply the world's seas and oceans each year, handling the bulk of international trade. Cargo ships are usually specially designed for the task, often being equipped with cranes and other mechanisms to load and unload, and come in all sizes. Today, they are almost always built of welded steel, and with some exceptions generally have a life expectancy of 25 to 30 years before being scrapped.
The canals of the United Kingdom are a major part of the network of inland waterways in the United Kingdom. They have a varied history, from use for irrigation and transport, through becoming the focus of the Industrial Revolution, to today's role of recreational boating. Despite a period of abandonment, today the canal system in the United Kingdom is again increasing in use, with abandoned and derelict canals being reopened, and the construction of some new routes. Canals in England and Wales are maintained by navigation authorities. The biggest navigation authorities are the Canal & River Trust and the Environment Agency, but other canals are managed by companies, local authorities or charitable trusts.
Yarrow Shipbuilders Limited (YSL), often styled as simply Yarrows, was a major shipbuilding firm based in the Scotstoun district of Glasgow on the River Clyde. It is now part of BAE Systems Surface Ships, owned by BAE Systems, which has also operated the nearby Govan shipyard since 1999.
Capesize ships are the largest dry cargo ships with ball mark dimension: about 170,000 DWT capacity, 290 m long, 45 m beam (wide), 18m draught. They are too large to transit the Suez Canal or Panama Canal, and so have to pass either Cape Agulhas or Cape Horn to traverse between oceans.
Port of Kolkata or Kolkata Port, officially known as Syama Prasad Mookerjee Port, is the only riverine major port in India, in the city of Kolkata, West Bengal, around 203 kilometres (126 mi) from the sea. It is the oldest operating port in India and was constructed by the British East India Company. Kolkata is a freshwater port with no variation in salinity. The port has two distinct dock systems – Kolkata Dock at Kolkata and a deep water dock at Haldia Dock Complex, Haldia.
Garden Reach Shipbuilders & Engineers Ltd, abbreviated as GRSE, is one of India's leading shipyards, located in Kolkata. It builds and repairs commercial and naval vessels. GRSE also exports the ships that the company builds.
The Alsace class was a pair of fast battleships planned by the French Navy in the late 1930s in response to German plans to build two H-class battleships after the Second London Naval Treaty collapsed. The Alsace design was based on variants of the Richelieu class, and three proposals were submitted by the design staff. The proposed armament included nine or twelve 380 mm (15 in) guns or nine 406 mm (16 in) guns, but no choice was definitively made before the program ended in mid-1940. According to one pair of historians, logistical considerations—including the size of the 12-gun variant and the introduction of a new shell caliber for the 406 mm version—led the naval command to settle on the nine 380 mm design. But another pair of authors disagree, believing that the difficulty of designing and manufacturing a three-gun turret would have caused prohibitive delays during wartime, making the third, largest variant the most likely to have been built. The ships would have forced the French government to make significant improvements to its harbor and shipyard facilities, as the smaller Richelieus already stretched the limitations of existing shipyards. With construction of the first member of the class scheduled for 1941, the plan was terminated by the German victory in the Battle of France in May–June 1940.
The Port of Southampton is a passenger and cargo port in the central part of the south coast of England. The modern era in the history of the Port of Southampton began when the first dock was inaugurated in 1843. After the Port of Felixstowe, Southampton is the second largest container terminal in UK, with a handled traffic of 1.5 million twenty-foot equivalent units (TEU). It also handles cruise ships, roll-on roll-off, dry bulk, and liquid bulk.
A&P Group Ltd is the largest ship repair and conversion company in the UK, with three shipyards located in Hebburn, Middlesbrough and Falmouth. The company undertakes a wide variety of maintenance and repair work on commercial and military ships with projects ranging from a two-day alongside repair period through to multimillion UK pound conversion projects lasting for a year or more.
Puran class of barge is a series of self-propelled fuel carrier built by Rajabagan Dockyard (RBD) for the Indian Navy.
The Haldia Port, officially Haldia Dock Complex (HDC), is a port on the confluence of the Haldi River and the Hooghly River. The port is located at Haldia in West Bengal, about 130 kilometres (81 mi) from the sandheads–deep sea area of the Bay of Bengal, 45 kilometres (28 mi) upstream from Pilotage Station at Sagar and 104 km downstream of Kolkata. In 1968, an oil jetty was commissioned at Haldia, and officially in 1977 the port facility of Haldia started functioning as a subsidiary port of the Port of Kolkata under the name Haldia Dock Complex.
An auxiliary floating drydock is a type of US Navy auxiliary floating dry dock. Floating dry docks are able to submerge underwater and to be placed under a ship in need of repair below the water line. Water is then pumped out of the floating dry dock, raising the ship out of the water. The ship becomes blocked on the deck of the floating dry dock for repair. Most floating dry docks have no engine and are towed by tugboats to their destinations. Floating dry docks come in different sizes to accommodate varying ship sizes, while large floating dry docks come in sections and can be combined to increase their size and lift power. Ballast pontoon tanks are flooded with water to submerge or pumped dry to raise the ship.
USS AFDM-2,, is an AFDM-3-class medium auxiliary floating drydock built in Mobile, Alabama by the Alabama Drydock and Shipbuilding Company for the U.S. Navy. Originally named USS YFD-4, Yard Floating Dock-4, she operated by Todd Shipyards at New Orleans, Louisiana for the repair of US ships during World War II. YFD-4 was renamed an Auxiliary Floating Dock Medium AFDM-2 in 1945 after the war.
Vlissingen Navy Drydock is a dry dock in Vlissingen. It is the oldest dry dock of the Netherlands, and is now a tourist attraction known as Dok van Perry.
The SS Alpena is a lake freighter. She was built in 1942 by the Great Lakes Engineering Works in Ecorse, Michigan, to carry iron ore. She was originally owned by the Pittsburgh Steamship Company, a subsidiary of United States Steel. After also hauling grain in addition to ore in the 1960s and 1970s, the ship was put into storage in 1982.
