Slipways
A slipway, also known as boat ramp or launch or boat deployer, is a Inclined plane, ramp on the shore by which ships or boats can be moved to and from the water. They are used for building and repairing ships and boats, and for launching and retrieving small boats on Boat trailer, trailers towed by automobiles and flying boats on their Landing gear, undercarriage. The nautical terms ways and skids are alternative names for slipway. A ship undergoing construction in a shipyard is said to be ''on the ways''. If a ship is Ship breaking, scrapped there, she is said to be ''broken up in the ways''. As the word "slip" implies, the ships or boats are moved over the ramp, by way of crane or fork lift. Prior to the move the vessel's Hull (watercraft), hull is coated with Grease (lubricant), grease, which then allows the ship or boat to "slip" off the ramp and progress safely into the water. Slipways are used to launch (newly built) large ships, but can only dry-dock or repair smaller ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petter Sørlle
Petter Sørlle (February 16, 1884 – May 29, 1933) was a Norway, Norwegian whaling captain and inventor. Biography Petter Martin Mattias Koch Sørlle was born at Tune (now Sarpsborg) in Østfold, Norway. Both his father and grandfather had been sailors. He was engaged in whaling from Vestfold and later participated in Antarctica whaling near the South Georgia Island and South Orkney Islands. He invented slipways for Whaler, whaling ships, which he patented in 1922. His invention was a device by which the whale could be fully drawn to the ship. The pickup slip was first used in the Antarctic Ocean by the whaling company Globus of Larvik on board the ''FLK Lancing'' during the season 1925–26. Sørlle was the first manager of the United Whalers whaling shore station at Stromness, South Georgia. He carried out surveys and is commemorated by several place names in Antarctica, Antarctic waters. Sørlle Buttress, the Sørlle Rocks and Cape Sørlle are all Antarctic features named af ...

Flensing
Flensing is the removing of the blubber or outer integument of whales, separating it from the animal's meat. Processing the blubber (the subcutaneous fat) into whale oil was the key step that transformed a whale carcass into a stable, transportable commodity. It was an important part of the history of whaling. The whaling that still continues in the 21st century is both industrial and aboriginal. In aboriginal whaling the blubber is rarely rendered into oil, although it may be eaten as '' muktuk''. Terminology English whalemen referred to the process as ''flensing'', while American whalemen called it ''cutting-in'' or ''flinching''. Open-boat Shore and bay whaling In Spitsbergen, in the first half of the 17th century, the processing of whales was primarily done ashore. Where the whale was flensed differed between the English and Dutch. The English brought the whale to the stern of the ship, where men in a boat cut strips of blubber from the whale's back. These were tied ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for taxiing, takeoff or landing. For aircraft, it is generally needed for all three of these. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or Seaplane, floats needed to operate from snow/ice/water and skids for vertical operation on land. Retractable undercarriages fold away during flight, which reduces drag (physics), drag, allowing for faster airspeeds. Landing gear must be strong enough to support the aircraft and its design affects the weight, balance and performance. It often comprises three wheels, or wheel-sets, giving a tripod effect.

Concrete
Concrete is a composite material composed of aggregate bound together with a fluid cement that cures to a solid over time. It is the second-most-used substance (after water), the most–widely used building material, and the most-manufactured material in the world. When aggregate is mixed with dry Portland cement and water, the mixture forms a fluid slurry that can be poured and molded into shape. The cement reacts with the water through a process called hydration, which hardens it after several hours to form a solid matrix that binds the materials together into a durable stone-like material with various uses. This time allows concrete to not only be cast in forms, but also to have a variety of tooled processes performed. The hydration process is exothermic, which means that ambient temperature plays a significant role in how long it takes concrete to set. Often, additives (such as pozzolans or superplasticizers) are included in the mixture to improve the physical prop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gravity
In physics, gravity (), also known as gravitation or a gravitational interaction, is a fundamental interaction, a mutual attraction between all massive particles. On Earth, gravity takes a slightly different meaning: the observed force between objects and the Earth. This force is dominated by the combined gravitational interactions of particles but also includes effect of the Earth's rotation. Gravity gives weight to physical objects and is essential to understanding the mechanisms responsible for surface water waves and lunar tides. Gravity also has many important biological functions, helping to guide the growth of plants through the process of gravitropism and influencing the circulation of fluids in multicellular organisms. The gravitational attraction between primordial hydrogen and clumps of dark matter in the early universe caused the hydrogen gas to coalesce, eventually condensing and fusing to form stars. At larger scales this results in galaxies and clust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lifeboat (rescue)
A rescue lifeboat is a boat rescue craft which is used to attend a vessel in distress, or its survivors, to rescue crew and passengers. It can be hand pulled, sail powered or powered by an engine. Lifeboats may be rigid, Inflatable boat, inflatable or rigid-inflatable combination-hulled vessels. Overview There are generally three types of boat, in-land (used on lakes and rivers), in-shore (used closer to shore) and off-shore (into deeper waters and further out to sea). A rescue lifeboat is a boat designed with specialised features for searching for, rescuing and saving the lives of people in peril at sea or other large bodies of water. In the United Kingdom and Ireland rescue lifeboats are typically vessels crewed by volunteers, intended for quick dispatch, launch and transit to reach a ship or individuals in trouble at sea. Off-shore boats are referred to as 'All-weather' and generally have a range of 150–250 nautical miles. Characteristics such as capability to withstand he ...

Factory Ship
A factory ship, also known as a fish processing vessel, is a large ocean-going vessel with extensive on-board facilities for processing and freezing caught fish or whales. Modern factory ships are automated and enlarged versions of the earlier whalers, and their use for fishing has grown dramatically. Some factory ships are equipped to serve as a mother ship. Background Contemporary factory ships have their origins in the early whalers. These vessels sailed into remote waters and processed the whale oil on board, discarding the carcass. Later whalers converted the entire whale into usable products. The efficiency of these ships and the predation they carried out on whales contributed greatly to the animals' steep decline. Contemporary factory ships are automated and enlarged versions of these earlier whalers. Their use for fishing has grown dramatically. For a while, Russia, Japan and Korea operated huge fishing fleets centred on factory ships, though in recent times this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winch
A winch is a mechanical device that is used to pull in (wind up) or let out (wind out) or otherwise adjust the tension (physics), tension of a rope or wire rope (also called "cable" or "wire cable"). In its simplest form, it consists of a Bobbin, spool (or drum) attached to a hand crank (mechanism), crank. Traditionally, winches on ships accumulated wire or rope on the drum; those that do not accumulate, and instead pass on the wire/rope (see yacht photo above), are called Capstan_(nautical), capstans. Despite this, sailboat capstans are most often referred to as winches. Winches are the basis of such machines as tow trucks, steam shovels and elevators. More complex designs have gear assemblies and can be powered by electric, hydraulic, pneumatic or internal combustion drives. It might include a solenoid brake and/or a Mechanical brake stretch wrapper, mechanical brake or ratchet (device), ratchet and pawl which prevents it unwinding unless the pawl is retracted. The rope may b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Cradle
A ship cradle is a rig designed to hold a ship or boat upright on dry land to allow the vessel to be built or repaired. The vessel is held in place in the cradle by wooden chocks, cables, sand bags or restraining fixtures on the cradle. Ship cradles are made of timber or steel and are usually built adjacent the seashore, lake or river side or on the floor of a dry dock A dry dock (sometimes drydock or dry-dock) is a narrow basin or vessel that can be flooded to allow a load to be floated in, then drained to allow that load to come to rest on a dry platform. Dry docks are used for the construction, maintenance, .... Overview "Cradle" may refer to the whole rig or sometimes each section of it. The cradle may be fixed to the dock floor, relying on the tides or a dry dock to drain it, or be equipped with wheels, running on an inclined track to allow the ship to be moved out of the water to a dry parking area. Large or heavy ships require steel railway wheels running on fixed s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
