Types of ships part 4

Hello friends,Today we will talk about the fourth part of the series of types of ships.

38) Cable Ships


Cable ship is a deep-sea vessel designed and used to lay underwater cables for telecommunications, electric power transmission, military, or other purposes. Cable ships are distinguished by large cable sheaves  for guiding cable over bow or stern or both. Bow sheaves. some very large, were characteristic of all cable ships in the past, but newer ships are tending toward having stern sheaves only, 

39) Heavy Lift Ships


A heavy-lift ship is a vessel designed to move very large loads that cannot be handled by normal ships. They are of two types:

Semi-submersible ships that take on water ballast to allow the load usually another vessel to be floated over the deck, whereupon the ballast is jettisoned and the ship's deck and cargo raised above the waterline.

Project cargo ships that use at least one heavy-lift crane for handling heavy cargo and sufficient ballast to assure stability and sea-keeping properties.


40) Floating Cranes and Sheerlegs


A floating cranes and sheerleg is a floating water vessel with a crane built on shear legs. Unlike other types of crane vessel, it is not capable of rotating its crane independently of its hull.

41) Barges and Pontoons 



42) Research Vessels

 

research vessel is a ship or boat designed, modified, or equipped to carry out research at sea. Research vessels carry out a number of roles. Some of these roles can be combined into a single vessel but others require a dedicated vessel. Due to the demanding nature of the work, research vessels are often constructed around an icebreaker hull, allowing them to operate in polar waters.

43) Survey Vessels


 
survey vessel is any type of ship or boat that is used for mapping. It is a type of research vessel.


44) Aircraft / Helicopter Carriers 



An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighters, strike aircraft, helicopters, and other types of aircraft. While heavier aircraft such as fixed-wing gunships and bombers have been launched from aircraft carriers, it is currently not possible to land them. By its diplomatic and tactical power, its mobility, its autonomy and the variety of its means, the aircraft carrier is often the centerpiece of modern combat fleets. Tactically or even strategically, it replaced the battleship in the role of flagship of a fleet. One of its great advantages is that, by sailing in international waters, it does not interfere with any territorial sovereignty and thus obviates the need for overflight authorizations from third-party countries, reduces the times and transit distances of aircraft and therefore significantly increase the time of availability on the combat zone.


45) Cruisers and Battleships 



Cruisers and battleships  was a type of capital ship of the first half of the 20th century. They were similar in displacement, armament and cost to battleships, but differed slightly in form and balance of attributes. Battlecruisers typically had slightly thinner armour and a lighter main gun battery than contemporary battleships, installed on a longer hull with much higher engine power in order to attain greater speeds


46) Destroyers and Frigates 


Frigates are thus usually used as escort vessels to protect sea lines of communication or as an auxiliary component of a strike group whereas destroyers are generally integrated into carrier battle groups as the air defence component or utilised to provide territorial air and missile defence.

47) Corvettes and Patrol Vessels


A corvette and patrol is small warships. It is traditionally the smallest class of vessel considered to be a proper (or "rated") warship. The warship class above the corvette is that of the frigate, while the class below was historically that of the sloop-of-war. The modern types of ship below a corvette are coastal patrol craft, missile boat and fast attack craft. In modern terms, a corvette is typically between 500 tons and 2,000 tons, although recent designs may approach 3,000 tons, which might instead be considered a small frigate.

48) Submarines

A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. It is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub.
