Parbuckling
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 fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Costa Concordia Disaster
On 13 January 2012, the eight-year-old Costa Cruises vessel ''Costa Concordia'' was on the last leg of a cruise around the Mediterranean Sea when she deviated from her planned route at Isola del Giglio, Tuscany, sailed closer to the island, and struck a rock formation on the sea floor. This caused the ship to list and then capsize, landing unevenly on an underwater ledge. Although a six-hour rescue effort brought most of the passengers ashore, 33 people died:27 passengers, five crew, and later, a member of the salvage team. An investigation focused on shortcomings in the procedures followed by ''Costa Concordia'' crew and the actions of her captain, Francesco Schettino, who left the ship prematurely. He left about 300 passengers on board the sinking vessel, most of whom were rescued by helicopter or motorboats in the area. Schettino was found guilty of manslaughter and sentenced to 16 years in prison. Despite receiving its own share of criticism, Costa Cruises and its parent c ...

Costa Concordia
''Costa Concordia'' () was a cruise ship operated by Costa Crociere. She was the first of her class, followed by sister ships ''Costa Serena'', ''Costa Pacifica'', ''Costa Favolosa'' and ''Costa Fascinosa'', and ''Carnival Splendor'' built for Carnival Cruise Line. When the 114,137-ton ''Costa Concordia'' and her sister ships entered service, they were among the largest ships built in Italy until the construction of the s. On 13 January 2012 at 21:45, ''Costa Concordia'' struck a rock in the Tyrrhenian Sea just off the eastern shore of Isola del Giglio. This tore open a gash on the port side of her hull, which soon flooded parts of the engine room, cutting power from the engines and ship services. As water flooded in and the ship listed, she drifted back towards the island and grounded near shore, then rolled onto her starboard side, lying in an unsteady position on a rocky underwater ledge. The evacuation of ''Costa Concordia'' took over six hours, and of the 3,229 passeng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MSC Napoli
''MSC Napoli'' was a United Kingdom-flagged container ship that developed a hull breach due to rough seas and slamming in the English Channel on 18 January 2007. She was deliberately run aground at Lyme Bay to avoid an environmental disaster and broken up by salvors. Early history The ship was built in 1991 and had a capacity of 4,419 TEU (62,000 tons). She was built by Samsung Heavy Industries, Kŏje, South Korea; owned by Metvale Ltd., a British Virgin Islands Brass Plate single entity company; managed by Zodiac Maritime; and was under charter to Mediterranean Shipping Company. On 27 March 2001, then named CMA CGM ''Normandie'', she was en route from Port Klang in Malaysia to the Indonesian capital, Jakarta when she ran aground on a reef in the Singapore Strait and remained stuck for several weeks. She was repaired by the Hyundai-Vinashin Shipyard in Khánh Hòa Province, Vietnam, which included the welding of more than 3,000 tonnes of metal onto the hull. Kyrill While e ...

MS Herald Of Free Enterprise
MS ''Herald of Free Enterprise'' was a roll-on/roll-off (RORO) ferry which capsized moments after leaving the Belgian port of Zeebrugge on the night of 6 March 1987, killing 193 passengers and crew. The eight-deck car and passenger ferry was owned by Townsend Thoresen, designed for rapid loading and unloading on the competitive cross-channel route. As was common at the time, it was built with no watertight compartments. The ship left harbour with her bow door open, and the sea immediately flooded the decks; within minutes, she was lying on her side in shallow water. The immediate cause of the capsizing was found to be negligence by the assistant boatswain, who was asleep in his cabin when he should have been closing the bow door. However, the official inquiry placed more blame on his supervisors and a general culture of poor communication in Townsend Thoresen. The vessel was salvaged, put up for sale, and sold to Naviera SA Kingstown on 30 September 1987, renamed ''Flushing Ran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sponson
Sponsons are projections extending from the sides of land vehicles, aircraft or watercraft to provide protection, stability, storage locations, mounting points for weapons or other devices, or equipment housing. Watercraft On watercraft, a sponson is a projection that extends outward (usually from the hull, but sometimes other parts of the vessel) to improve stability while floating, or to act as a securing point for other equipment. Vessels with unstable body shapes or unevenly distributed weight are likely to feature sponsons to help prevent capsizing or other instabilities. On many vessels, these projections from the main body of the vessel can be attached and removed quickly and fairly easily. Canoes and kayaks sometimes feature sponson attachments as well, for stability in rough waters. These differ from outriggers, which extend a significant distance away from the body of the craft, and are employed on craft designed for open waters. A sponson's terminus is close to the cr ...

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 ...
