Bollard Pull
Bollard pull is a conventional measure of the pulling (or towing) power of a watercraft. It is defined as the force (usually in tonnes-force or kilonewtons (kN)) exerted by a vessel under full power, on a shore-mounted bollard through a tow-line, commonly measured in a practical test (but sometimes simulated) under test conditions that include calm water, no tide, level trim, and sufficient depth and side clearance for a free propeller stream. Like the horsepower or mileage rating of a car, it is a convenient but idealized number that must be adjusted for operating conditions that differ from the test. The bollard pull of a vessel may be reported as two numbers, the ''static'' or ''maximum'' bollard pull – the highest force measured – and the ''steady'' or ''continuous'' bollard pull, the average of measurements over an interval of, for example, 10 minutes. An equivalent measurement on land is known as drawbar pull, or tractive force, which is used to measure the total hori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voith Schneider Propeller
The Voith Schneider Propeller (VSP) is a specialized marine propulsion system (MPS) manufactured by the Voith Group based on a cyclorotor design. It is highly maneuverable, being able to change the direction of its thrust almost instantaneously. It is widely used on tugs and ferries. Operation From a circular plate, rotating around a vertical axis, a circular array of vertical blades (in the shape of hydrofoils) protrude out of the bottom of the ship. Each blade can rotate itself around a vertical axis. The internal gear changes the angle of attack of the blades in sync with the rotation of the plate, so that each blade can provide thrust in any direction. Unlike the azimuth thruster (where a conventional propeller is rotated about the vertical axis to direct its thrust, allowing a vessel to steer without the use of a rudder), the Voith-Schneider drive merely requires changing the pattern of orientation of the vertical blades. In a marine situation, this provides for a d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Active Indian Navy Ships
The Indian Navy (IN), which is the naval warfare branch of the Indian Armed Forces, has approximately 135+ warships on active commission. By forethought, the IN's Maritime Capability Perspective Plan (MCPP) for the period 2012–2027 had set the objective of the service becoming a 200-ship fleet by 2035; however, that number has since been reduced to 175 in December 2019 – principally owing the IN's dearth of budgetary founding, its ageing fleet and delays in the construction of naval assets. By certain calculations, the IN is still estimated to comprise a future total of 155-160 ships by 2030. By inventory, the IN's principal assets include its Fleet carrier, aircraft carrier component – the service has operated a total of four aircraft carriers since 1961; its List of submarines of the Indian Navy, submarine component – which presently includes a Nuclear deterrence, strategic submarine force; and its Amphibious assault ship, amphibious component – which principally o ...

Tugs Of The Indian Navy
A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbors or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, and some are icebreakers or salvage tugs. Early models were powered by steam engines, which were later superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours. Types Seagoing Seagoing tugs (deep-sea tugs or ocean tugboats) fall into four basic categories: #The standard seagoing tug with model bow that tows almost exclusively by way of a wire cable. In some rare cases, such as some USN fleet tugs, a synthetic rope hawser may be used for the tow in the belief that the line can be pulled aboard a disabled ship by the crew owing to its li ...
