Marchioness Disaster
The ''Marchioness'' disaster was a collision between two vessels on the River Thames in London in the early hours of 20 August 1989, which resulted in the deaths of 51 people. The pleasure steamer ''Marchioness'' sank after being hit twice by the dredger ''Bowbelle'' at about 1:46 am, between Cannon Street railway bridge and Southwark Bridge. ''Marchioness'' had been hired for the evening for a birthday party and had about 130 people on board, four of whom were crew and bar staff. Both vessels were heading downstream, against the tide, ''Bowbelle'' travelling faster than the smaller vessel. Although the exact paths taken by the ships, and the precise series of events and their locations, are unknown, the subsequent inquiry considered it likely that ''Bowbelle'' struck ''Marchioness'' from the rear, causing the latter to turn to port, where she was hit again, then pushed along, turning over and being pushed under ''Bowbelle''s bow. It took thirty seconds for ''Marchio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dunkirk Evacuation
The Dunkirk evacuation, codenamed Operation Dynamo and also known as the Miracle of Dunkirk, or just Dunkirk, was the evacuation of more than 338,000 Allies of World War II, Allied soldiers during the World War II, Second World War from the beaches and harbour of Dunkirk, in the north of French Third Republic, France, between 26 May and 4 June 1940. The operation commenced after large numbers of Belgian Armed Forces, Belgian, British Army, British, and French Army, French troops were cut off and surrounded by German Army (1935–1945), German troops during the six-week Battle of France. In a speech to the House of Commons of the United Kingdom, House of Commons, British Prime Minister Winston Churchill called this "a colossal military disaster", saying "the whole root and core and brain of the British Army" had been stranded at Dunkirk and seemed about to perish or be captured. In his "We shall fight on the beaches" speech on 4 June, he hailed their rescue as a "miracle of delive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Able Seamen
An able seaman (AB) is a Sailor, seaman and member of the deck department of a merchant ship with more than two years' experience at sea and considered "well acquainted with his duty". An AB may work as a watchstander, a day worker, or a combination of these roles.

Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Deadweight Tonnage
Deadweight tonnage (also known as deadweight; abbreviated to DWT, D.W.T., d.w.t., or dwt) or tons deadweight (DWT) is a measure of how much weight a ship can carry. It is the sum of the weights of cargo, fuel, fresh water, ballast water, provisions, passengers, and crew. DWT is often used to specify a ship's maximum permissible deadweight (i.e. when it is fully loaded so that its Plimsoll line is at water level), although it may also denote the actual DWT of a ship not loaded to capacity. Definition Deadweight tonnage is a measure of a vessel's weight carrying capacity, not including the empty weight of the ship. It is distinct from the displacement (weight of water displaced), which includes the ship's own weight, or the volumetric measures of gross tonnage or net tonnage (and the legacy measures gross register tonnage and net register tonnage). Deadweight tonnage was historically expressed in long tonsOne long ton (LT) is but is now usually given internationally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Troon
Troon is a town in South Ayrshire, situated on the west coast of Ayrshire in Scotland, about north of Ayr and northwest of Glasgow Prestwick Airport. Troon has a port with freight services and a yacht marina. Up until January 2016, P&O operated a seasonal ferry service to Larne. In May 2006, a ferry service to Campbeltown was added, although this was withdrawn the following year. In the 2001 census the population of Troon, not including the nearby village of Loans but including the Barassie area, was estimated at 14,766, a 4.77% increase on the 1991 estimate of 14,094. Name The name ''Troon'' is likely from a Brythonic or Pictish name cognate with Welsh ("nose, cape"). When Scottish Gaelic became the main language, it is possible that the Gaelic form (; "the nose") was used for the name Troon. Since the words ''sròn'' and ''trwyn'' are cognate, it could have been easily adapted from one language to the other. This is similar to the Gaelic name of Stranraer (''An t-S ...

Construction Aggregate
Construction aggregate, or simply aggregate, is a broad category of coarse- to medium-grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world. Aggregates are a component of composite materials such as concrete and asphalt; the aggregate serves as reinforcement to add strength to the overall composite material. Due to the relatively high hydraulic conductivity value as compared to most soils, aggregates are widely used in drainage applications such as foundation and French drains, septic drain fields, retaining wall drains, and roadside edge drains. Aggregates are also used as base material under foundations, roads, and railroads. In other words, aggregates are used as a stable foundation or road/rail base with predictable, uniform properties (e.g. to help prevent differential settling under the road or building), or as a low-cost exte ...

Waterman (occupation)
A waterman is a river worker who transfers passengers across and along city centre rivers and estuaries in the United Kingdom and its colonies. Most notable are those on the River Thames and River Medway in England, but other rivers such as the River Tyne and River Dee, Wales, also had their watermen who formed guilds in medieval times. Waterman can also be a person who navigates a boat carrying passengers. These boats were often rowing boat or boats with sails. Over the years watermen acquired additional skills such as local pilotage, mooring vessels at berths, jetties, buoys, and docks, and acting as helmsman aboard large vessel. Watermen in the United Kingdom: 1197 to 1859 Watermen or wherrymen were an essential part of early London. Using a small boat called a wherry or skiff they would ferry passengers along and across the river. With bad rural roads and narrow congested city streets, the Thames was the most convenient highway in the region. Until the mid-18th century Londo ...

Chief Mate
A chief mate (C/M) or chief officer, usually also synonymous with the first mate or first officer, is a licensed mariner and head of the deck department of a merchant ship. The chief mate is customarily a watchstander and is in charge of the ship's cargo and deck crew. The actual title used will vary by ship's employment, by type of ship, by nationality, and by trade: for instance, ''chief mate'' is not usually used in the Commonwealth, although ''chief officer'' and ''first mate'' are; on passenger ships, the first officer may be a separate position from that of the chief officer that is junior to the latter. The chief mate answers to the captain for the safety and security of the ship. Responsibilities include the crew's welfare and training in areas such as safety, firefighting, search and rescue. Senior on board Operations Manager The Chief Mate, who is the second in command of the vessel, is often equated, in corporate terms, to a senior manager for the operations o ...
