Sheerleg
A floating sheerleg (also: shearleg) is a floating water vessel with a Crane (machine), crane built on shear legs. Unlike other types of crane vessel, it is not capable of rotating its crane independently of its hull. There is a huge variety in sheerleg capacity. The smaller cranes start at around 50 tons in lifting capacity, with the largest being able to lift 10,000 tons. The bigger sheerlegs usually have their own propulsion system and have a large accommodation facility on board, while smaller units are floating Pontoon (boat), pontoons that need to be towed to their workplace by tugboats. Sheerlegs are commonly used for Marine salvage, salvaging ships, assistance in shipbuilding, Stevedore, loading and unloading large cargo into ships, and bridge building. They have grown considerably larger over the last decades due to a marked increase in vessel, cargo, and component size (of ships, offshore oil rigs, and other large fabrications), resulting in heavier lifts both during c ...

Crane Vessel
A crane vessel, crane ship or floating crane is a ship with a crane specialized in lifting heavy loads. The largest crane vessels are used for offshore construction. Conventional monohulls are used, but the largest crane vessels are often catamaran or semi-submersible types as they have increased stability. On a sheerleg crane, the crane is fixed and cannot rotate, and the vessel therefore is manoeuvered to place loads. History In medieval Europe, crane vessels which could be flexibly deployed in the whole port basin were introduced as early as the 14th century. During the age of sail, the sheer hulk was used extensively as a floating crane for tasks that required heavy lift. At the time, the heaviest single components of ships were the main masts, and sheer hulks were essential for removing and replacing them, but they were also used for other purposes. Some crane vessels had engines for propulsion, others needed to be towed with a tugboat. In 1920, the 1898-built battle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shear Legs
Shear legs, also known as sheers, shears, or sheer legs, are a form of two-legged lifting device. Shear legs may be permanent, formed of a solid A-frame and supports, as commonly seen on land and the floating sheerleg, or temporary, as aboard a vessel lacking a fixed crane or derrick. When fixed, they are often used for very heavy lifting, as in tank recovery, shipbuilding, and offshore salvage operations. At dockyards they hoist masts and other substantial rigging parts on board. They are sometimes temporarily rigged on sailboats for similar tasks. Uses On land Shear legs are a lifting device related to the gin pole, derrick and tripod (lifting device). Shears are an A-frame of any kind of material such as timbers or metal, the feet resting on or in the ground or on a solid surface which will not let them move and the top held in place with guy-wires or guy ropes simply called "guys". Shear legs only need two guys whereas a gin pole needs at least three. The U. S. Army Fiel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pioneering Spirit
''Pioneering Spirit'' (formerly ''Pieter Schelte'') is a catamaran crane vessel owned by the Switzerland-based Allseas Group designed for the single-lift installation and removal of large oil and gas platforms and the installation of record-weight pipelines. The , vessel is the world's largest vessel by gross tonnage, and since September 2021 also the largest floating sheerleg in the world. It was built in South Korea by Daewoo Shipbuilding & Marine Engineering in 2013 at a cost of €2.6 billion. It commenced offshore operations in August 2016. Development The initial concept, by Allseas technical director W.P. Kaldenbach, was of a vessel capable of lifting entire platforms, and in 1987 Allseas declared its intention to build it. The initial idea featured two rigidly connected, self-propelled supertankers, with a large slot at the bows enabling it to install platform topsides in one piece. Early designs featured a flotation and ballasting system and active motion compensa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Left Coast Lifter
''Left Coast Lifter'' is a floating derrick barge or sheerleg which was built to assist in the eastern span replacement of the San Francisco–Oakland Bay Bridge. The barge carries a shear legs crane which is the largest barge crane ever used on the U.S. West Coast. The barge's name is taken from " Left Coast", a slang term for the West Coast of the United States (which appears on the left side of a typical map and also refers to the region's liberal, or "left leaning", political tradition). Operational history ''Left Coast Lifter'' was built for the American Bridge/Fluor joint venture (ABFJV), which was the lead contractor on the self-anchored suspension eastern span replacement. The barge was built in Portland, Oregon by U.S. Barge, LLC and ferried to Shanghai, where it was fitted with a shear-leg crane manufactured by Shanghai Zhenhua Port Machinery Co. Ltd (ZPMC). The completed sheerleg was ferried back to the United States on a semi-submersible heavy-lift ship, ''Zh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saipem
Saipem S.p.A. (Società Anonima Italiana Perforazioni E Montaggi lit. ''Drilling and Assembly Italian Public Limited Company'') is an Italian multinational oilfield services company and one of the largest in the world. Until 2016 it was a subsidiary of Italian oil and gas supermajor Eni, which retains approximately 30% of Saipem's shares. History Early history The history of Saipem is deeply connected to Enrico Mattei's management era of Eni during the years of the Italian economic miracle. In the early 1950s Mattei had reorganized the Italian oil industry through a complex system of outright acquisitions and government investments, in order to guarantee Italy's self-reliance in energy. At first, Mattei focused on natural gas, the only abundant source of energy available in mainland Italy, through Snam, a newly formed gas pipelines company. In the late 1950s, Eni's subsidiary Snam came to head two sub-holdings: Snam Montaggi, created in 1955 to build pipelines and drilling ...

Antwerp Port Authority
The Port of Antwerp-Bruges is the port of the City of Antwerp. It is located in Flanders (Belgium), mainly in the province of Antwerp but also partially in the province of East Flanders. It is a seaport in the heart of Europe accessible to capesize ships. It is Europe’s second-largest seaport, after Rotterdam. Antwerp stands at the upper end of the tidal estuary of the Scheldt. The estuary is navigable by ships of more than 100,000 Gross Tons as far as 80 km inland. Like the Port of Hamburg, the Port of Antwerp's inland location provides a more central location in Europe than the majority of North Sea ports. Antwerp's docks are connected to the hinterland by rail, road, and river and canal waterways. As a result, the port of Antwerp has become one of Europe's largest seaports, ranking second behind Rotterdam by total freight shipped. Its international rankings vary from 11th to 20th ( AAPA). In 2012, the Port of Antwerp handled 14,220 sea trade ships (190.8 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
