Parbuckle Salvage
Parbuckle salvage, or ''parbuckling'', is the righting of a sunken vessel using rotational leverage. A common operation with smaller watercraft, parbuckling is also employed to right large vessels. In 1943, the was rotated nearly 180 degrees to upright after being sunk in the attack on Pearl Harbor, and the Italian cruise ship ''Costa Concordia'' was successfully parbuckled off the west coast of Italy in September 2013, the largest salvage operation of that kind to date. Mechanical advantage and difficulties While the mechanical advantage used by a laborer to parbuckle a cask up an incline is 2:1, parbuckling salvage is not so limited. Each of the 21 winches used to roll the ''Oklahoma'' used cables that passed through two 17-part tackle assemblies (17:1 advantage). Eight diameter sheaves, eight diameter sheaves, and one diameter sheave comprised just half the mechanical effort. A major concern during salvage is preventing rotational torque from becoming a transverse forc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Isola Del Giglio
Isola del Giglio (; en, Giglio Island, lat, Igilium) is an Italian island and comune in the Tyrrhenian Sea, off the coast of Tuscany, and is part of the Province of Grosseto. The island is one of seven that form the Tuscan Archipelago, lying within the Arcipelago Toscano National Park. ''Giglio'' means "lily" in Italian, and though the name would appear consistent with the insignia of Medici Florence, it originally derives from the Latin name of the island, ''Igilium'', which in turn could be related to the Ancient Greek name of the neighbouring Capraia, ''Αἰγύλιον'' (''Aigýlion'', Latinized as ''Aegilium''), from grc, αἴξ, , goat, translit=aíx. In 2012, the cruise ship ''Costa Concordia'' foundered off the coast of the island. Geography The island is separated by a stretch of sea from the nearest point of the mainland, the promontory of Monte Argentario. Mainly mountainous, it consists almost entirely of granite, culminating in the Poggio della Pagana, whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jackup Rig
A jackup rig or a self-elevating unit is a type of mobile platform that consists of a buoyant hull fitted with a number of movable legs, capable of raising its hull over the surface of the sea. The buoyant hull enables transportation of the unit and all attached machinery to a desired location. Once on location the hull is raised to the required elevation above the sea surface supported by the sea bed. The legs of such units may be designed to penetrate the sea bed, may be fitted with enlarged sections or footings, or may be attached to a bottom mat. Generally jackup rigs are not self-propelled and rely on tugs or heavy lift ships for transportation. Jackup platforms are almost exclusively used as exploratory oil and gas drilling platforms and as offshore and wind farm service platforms. Jackup rigs can either be triangular in shape with three legs or square in shape with four legs. Jackup platforms have been the most popular and numerous of various mobile types in existence. The ...

Fishing Vessel
A fishing vessel is a boat or ship used to catch fish in the sea, or on a lake or river. Many different kinds of vessels are used in commercial, artisanal and recreational fishing. The total number of fishing vessels in the world in 2016 was estimated to be about 4.6 million, unchanged from 2014. The fleet in Asia was the largest, consisting of 3.5 million vessels, accounting for 75 percent of the global fleet. In Africa and North America the estimated number of vessels declined from 2014 by just over 30,000 and by nearly 5,000, respectively. For Asia, Latin America and the Caribbean and Oceania the numbers all increased, largely as a result of improvements in estimation procedures.FAO 2007 It is difficult to estimate the number of recreational fishing boats. They range in size from small dinghies to large charter cruisers, and unlike commercial fishing vessels, are often not dedicated just to fishing. Prior to the 1950s there was little standardisation of fishing boats. Desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fishing Trawler
A fishing trawler is a commercial fishing vessel designed to operate Trawling, fishing trawls. Trawling is a method of fishing that involves actively dragging or pulling a trawl through the water behind one or more trawlers. Trawls are fishing nets that are pulled along the bottom of the sea or in midwater at a specified depth. A trawler may also operate two or more trawl nets simultaneously (double-rig and multi-rig). There are many variants of trawling gear. They vary according to local traditions, bottom conditions, and how large and powerful the trawling boats are. A trawling boat can be a small open boat with only 30 horsepower (22 kW) or a large factory ship with 10,000 horsepower (7457 kW). Trawl variants include beam trawls, large-opening midwater trawls, and large bottom trawls, such as "rock hoppers" that are rigged with heavy rubber wheels that let the net crawl over rocky bottom.

Barge
Barge nowadays generally refers to a flat-bottomed inland waterway vessel which does not have its own means of mechanical propulsion. The first modern barges were pulled by tugs, but nowadays most are pushed by pusher boats, or other vessels. The term barge has a rich history, and therefore there are many other types of barges. History of the barge Etymology "Barge" is attested from 1300, from Old French ''barge'', from Vulgar Latin ''barga''. The word originally could refer to any small boat; the modern meaning arose around 1480. ''Bark'' "small ship" is attested from 1420, from Old French ''barque'', from Vulgar Latin ''barca'' (400 AD). The more precise meaning of Barque as "three-masted sailing vessel" arose in the 17th century, and often takes the French spelling for disambiguation. Both are probably derived from the Latin ''barica'', from Greek ''baris'' "Egyptian boat", from Coptic ''bari'' "small boat", hieroglyphic Egyptian D58-G29-M17-M17-D21-P1 and similar ''b ...
