IRS-class Tugboat
The IRS class of tugboats are a series of Bollard pull tugboats built by Hindustan Shipyard Limited, Visakhapatnam, for the Indian Navy. INS ''Sahas'' and INS ''Dhiraj'' tugs were flagged off by Commander (retd) K.S. Subramanian, the Director (shipbuilding) and INS ''Himmat'' was flagged off by Rear Admiral (Retd) N K Mishra, NM Chairman & Managing Director of HSL. The vessels were built under special survey of IRS Steel ship rules and as such were assigned with IRS class notation. Contracts for 4 additional similar tugboats were signed between HSL and Indian Navy in November 2019. The keel of the first two tugboats ''Veeran'' and ''Balaram'' were laid on November 15, 2019. The new tugboats are to be stationed at Visakhapatnam, the future home base of to handle the aircraft carrier once it is commissioned into Indian Navy in 2022. Specifications Each of these tugboats can achieve against a design speed of at 85% maximum continuous rating. Bollard pull of all the vessels is ...

Voith Schneider
A cyclorotor, cycloidal rotor, cycloidal propeller or cyclogiro, is a fluid propulsion device that converts shaft power into the acceleration of a fluid using a rotating axis perpendicular to the direction of fluid motion. It uses several blades with a spanwise axis parallel to the axis of rotation and perpendicular to the direction of fluid motion. These blades are cyclically pitched twice per revolution to produce force (thrust or lift) in any direction normal to the axis of rotation. Cyclorotors are used for propulsion, lift, and control on air and water vehicles. An aircraft using cyclorotors as the primary source of lift, propulsion, and control is known as a cyclogyro or cyclocopter. A unique aspect is that it can change the magnitude and direction of thrust without the need of tilting any aircraft structures. The patented application, used on ships with particular actuation mechanisms both mechanical or hydraulic, is a Voith Schneider Propeller. Operating principle The b ...

Tugboat
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 t ...

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] |
Hindustan Shipyard Limited
Hindustan Shipyard Limited (HSL) is a public sector undertaking shipyard located in Visakhapatnam, on the east coast of India. HSL is a major shipyard in India, with a capacity to manufacture vessels up to 80,000 deadweight tonnage (DWT). The shipyard is the 2nd biggest after Cochin Shipyard. History Founded as the ''Scindia Shipyard'', it was built by industrialist Walchand Hirachand as a part of The Scindia Steam Navigation Company Ltd. Walchand selected Visakhapatnam as a suitable location for the construction of the yard and took possession of the land in November 1940. The foundation stone for the shipyard was laid by Dr. Rajendra Prasad on 21 June 1941, who was at that time the acting Congress President. The first ship to be constructed fully in India after independence was built at the Scindia Shipyard and named ''Jal Usha''. It was launched in 1948 by Jawaharlal Nehru at a ceremony where the families of Seth Walchand Hirachnd, late Narottam Morarjee, and Tulsidas K ...

Karwar
Karwar is a coastal City and the administrative headquarters of Uttara Kannada district, formerly part of the Bombay Presidency, located at the mouth of the Kali River (Karnataka), Kali river along the Konkan Coast in the present-day state of Karnataka, India. Etymology Karwar, also known locally as "Kādwād", derived its name from the nearby village of "Kade-Wādā". In the local Konkani language, Konkani, ''Kade'' means "Last" and ''Wādā'' means "Ward". Hence, ''Kade-Wādā'' ("the last neighbourhood") referred to the southernmost Konkani-speaking village. During the British Raj, Crown rule in India, the name "Karwar" was spelt as "Carwar". The ancient name was "Baithkhol"—from an Arabic language, Arabic term ''Bait-e-kol''— meaning the "bay of safety". This is in the Indian history for maritime trade wherein black peppercorns, cardamom, and muslin cloth were exported from this Kādwād port and after the war with Veer Henja Naik (1803), the port activities were shif ...

Aircraft Carrier
An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and hangar facilities for supporting, arming, deploying and recovering carrier-based aircraft, shipborne aircraft. Typically it is the capital ship of a naval fleet, fleet (known as a carrier battle group), as it allows a naval force to power projection, project seaborne naval aviation, air power far from homeland without depending on local airfields for staging area, staging aerial warfare, aircraft operations. Since their inception in the early 20th century, aircraft carriers have evolved from wooden vessels used to deploy individual tethered reconnaissance balloons, to nuclear marine propulsion, nuclear-powered supercarriers that carry dozens of fighter aircraft, fighters, strike aircraft, military helicopters, airborne early warning and control, AEW&Cs and other types of aircraft such as unmanned combat aerial vehicle, UCAVs.

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 ...
