Léon Thévenin (ship)
The ''Léon Thévenin'' is a French cable-laying vessel named in honor of French engineer Léon Charles Thévenin. The ''Léon Thévenin'' was famously used in conjunction with a robot submarine named ''Scarab 1'' for recovering the flight data recorder (FDR) and cockpit voice recorder (CVR) boxes from Air India Flight 182 that was destroyed in mid-air by a bomb as it was crossing Irish airspace, on 23 June 1985. By 4 July, the sonar of the British ship '' Guardline Locater'' had detected signals on the seabed and on 9 July the CVR was pin-pointed and raised to the surface by the ''Scarab 1''. The next day the FDR was located and recovered. It is currently owned and operated by Orange Marine, operating out of the Port of Cape Town The Port of Cape Town is the port of the city of Cape Town, South Africa. It is situated in Table Bay. Because of its position along one of the world's busiest trade routes it is one of the busiest ports in South Africa, handling the larges ...

Flag Of Mauritius
The national flag of Mauritius, also known as the Four Bands and ''Les Quatre Bandes'' ( French for "the four bands"), was adopted upon independence, March 12, 1968. It consists of four horizontal bands of equal width, coloured (from top to bottom) red, blue, yellow, and green. The flag was recorded at the College of Arms in London on 9 January 1968. The flag was designed by Gurudutt Moher whose contribution was recognised posthumously in March 2018 in the form of the national title ''Member of the Star and Key of the Indian Ocean'' (MSK). Moher, who was a retired school teacher, died of a heart attack on October 7, 2017, at the age of 93. The civil ensign (for private vessels) and government ensign (for state vessels) are red and blue flags, respectively, each with the national flag in the canton and the coat of arms of Mauritius in the fly. The naval ensign (used by coast guard vessels) is an unusual design consisting of red, white, and blue vertical stripes of unequal width ...

CS Chamarel
The CS ''Chamarel'', originally CS ''Vercors'' was a cable layer owned by France Telecom Marine, laying submarine communications cables around the world. It was built in 1974 and destroyed by a fire in August 2012. As the ''Vercors'', the ship laid cables on and between all continents except Antarctica, including numerous trans-Atlantic cables and the first ever Israeli-made cable, and set the record for the deepest submarine buried cable lay in 2000. The ship was badly damaged by a fire and driven aground on 8 August 2012. History Service The ''Vercors'' was built in 1974 by the Société Nouvelle des Ateliers et Chantiers du Havre. It started operation out of La Seyne-sur-Mer in 1975. In the 1970s it laid cables to and from France, including the now-decommissioned ANNIBAL, except ANTINEA, which stretched from Morocco to the Ivory Coast through Senegal. In the 1980s the ''Vercors'' laid the ATLANTIS between Portugal and Senegal, TAT-7 and TAT-8, and others across most con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Of Cape Town
The Port of Cape Town is the port of the city of Cape Town, South Africa. It is situated in Table Bay. Because of its position along one of the world's busiest trade routes it is one of the busiest ports in South Africa, handling the largest amount of fresh fruit and second only to Durban as a container port. The port also has significant repair and maintenance facilities that are used by several large fishing fleets and parts of the West African oil industry. Because of the many tourist attractions offered by Cape Town and its surrounding region, many cruise ships also berth in the port. History The history of the port follows that of Cape Town, which traces its roots back to 6 April 1652 when Jan van Riebeeck of the Dutch East India Company (VOC) established a revictualing station there. Earlier explorers had called it Table Bay from the late 15th century onwards. The first harbour construction was a jetty built in 1654 by Jan van Riebeeck. Ships all anchored in ...

Seabed
The seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as 'seabeds'. The structure of the seabed of the global ocean is governed by plate tectonics. Most of the ocean is very deep, where the seabed is known as the abyssal plain. Seafloor spreading creates mid-ocean ridges along the center line of major ocean basins, where the seabed is slightly shallower than the surrounding abyssal plain. From the abyssal plain, the seabed slopes upward toward the continents and becomes, in order from deep to shallow, the continental rise, slope, and shelf. The depth within the seabed itself, such as the depth down through a sediment core, is known as the “depth below seafloor.” The ecological environment of the seabed and the deepest waters are collectively known, as a habitat for creatures, as the “benthos.” Most of the seabed throughout the world's oceans is covered in layers of marine sediments. ...

Bomb
A bomb is an explosive weapon that uses the Exothermic process, exothermic reaction of an explosive material to provide an extremely sudden and violent release of energy. Detonations inflict damage principally through ground- and atmosphere-transmitted mechanical stress (mechanics), stress, the impact and penetration of pressure-driven projectiles, pressure damage, and explosion-generated effects. Bombs have been utilized since the 11th century starting in East Asia. The term bomb is not usually applied to explosive devices used for civilian purposes such as construction or mining, although the people using the devices may sometimes refer to them as a "bomb". The military use of the term "bomb", or more specifically aerial bomb action, typically refers to airdropped, unpowered explosive weapons most commonly used by air forces and naval aviation. Other military explosive weapons not classified as "bombs" include shell (projectile), shells, depth charges (used in water), or lan ...

Flight Recorder
A flight recorder is an electronic recording device placed in an aircraft for the purpose of facilitating the investigation of aviation accidents and incidents. The device may often be referred to as a "black box", an outdated name which has become a misnomer—they are now required to be painted bright orange, to aid in their recovery after accidents. There are two types of flight recording devices: the flight data recorder (FDR) preserves the recent history of the flight through the recording of dozens of parameters collected several times per second; the cockpit voice recorder (CVR) preserves the recent history of the sounds in the cockpit, including the conversation of the pilots. The two devices may be combined into a single unit. Together, the FDR and CVR objectively document the aircraft's flight history, which may assist in any later investigation. The two flight recorders are required by international regulation, overseen by the International Civil Aviation Organizat ...

Air India Flight 182
Air India Flight 182 was an Air India flight operating on the Montreal–London–Delhi–Bombay route. On 23 June 1985, it was operated using Boeing 747-237B registered ''VT-EFO''. It disintegrated in mid-air en route from Montreal to London, at an altitude of over the Atlantic Ocean, as a result of an explosion from a bomb planted by Canadian Sikh terrorists. The remnants of the airliner fell into the ocean approximately off the coast of Ireland, killing all 329 people aboard, including 268 Canadian citizens, 27 British citizens, and 24 Indian citizens. The bombing of Air India Flight 182 is the deadliest aviation incident in the history of Air India and was the world's deadliest act of aviation terrorism until the September 11 attacks in 2001. Investigators found the attack was a part of a larger transnational terrorist plot and had included two attempted plane bombings. The first bomb was meant to explode aboard Air India Flight 301, which was scheduled to take off fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remotely Operated Underwater Vehicle
A remotely operated underwater vehicle (technically ROUV or just ROV) is a tethered underwater mobile device, commonly called ''underwater robot''. Definition This meaning is different from remote control vehicles operating on land or in the air. ROVs are unoccupied, usually highly maneuverable, and operated by a crew either aboard a vessel/floating platform or on proximate land. They are common in deepwater industries such as offshore hydrocarbon extraction. They are linked to a host ship by a neutrally buoyant tether or, often when working in rough conditions or in deeper water, a load-carrying umbilical cable is used along with a tether management system (TMS). The TMS is either a garage-like device which contains the ROV during lowering through the splash zone or, on larger work-class ROVs, a separate assembly which sits on top of the ROV. The purpose of the TMS is to lengthen and shorten the tether so the effect of cable drag where there are underwater currents is minimize ...
