Technological advancements have given rise to Computer Aided Design and simulation which are used in Ship Design. Considering that Naval Architects do not have the luxury of prototypes, the virtual ships offer direction when it comes to construction and design of ships before they are built.
Some innovative ships have thus developed and broke the stereotypes in design. This has resulted in unconventional shipbuilding as opposed to the traditional ship designs.
World’s First Floating Liquefied Natural Gas Platform – Shell Prelude
This shell prelude is the world’s first floating liquefied natural gas platform. It is also the largest offshore facility ever constructed. It is under construction by Samsung Heavy Industries in South Korea for Royal Dutch Shell. It is 488 meters long, 74 meters wide, and is made with more than 260,000 tons of steel which requires advanced steering and anchoring technology to deal with the fluid and wind dynamics of open sea. Upon completion, it is estimated to carry 600,000 tons of gas surpassing any aircraft carriage. The facility is designed to brave all-weather events and is equipped to withstand a category 5 cyclone.
E ship 1: Magnus Sailing
This is one of the most unique looking ship designs ever, with a superstructure resembling a factory chimney. Actually these ‘chimneys’ are called Flettener Rotors being named Anton Flettner, who first constructed the first rotor ships in the 1920’s. These ships use the famous Magnus effect to propel the ships. Similar to banana kicks in football, the pressure difference created on a spinning body (the Flettner Rotor) causes it’s displacement along the same, only here all the rotors aboard such ships are electronically maneuvered by on-board wind sensing and control system allowing it to move. The four rotors are built exceptionally high because air is used as the chief fluid to generate thrust. Typically the size of the rotors offers a large surface area to maximize thrust.
The Bottsand Class Oil Recovery Vessel – Ship That Splits Into Two
Oil recovery vessels have often been used as a collection method of contaminated seawater by slight changes in propulsion machinery alignment. The German Navy’s icebreaker Baltika also doubles up as an oil recovery vessel. The ship literally ‘eats’ into the oil deposition from oil spills and stores it into its recovery tanks where the water and oil is separated. By split along the length, it allows a larger area for trapping the oil contaminated water. It is flexible and time saving. The ship makes use of the twin hull concept which has greater transverse stability as compared to a single hull design which has a bow opening mechanism.
Ramform Titan Class Seismic Vessels
At first glance, the ship appears to be sliced off from the mid body. Rather, it is another novel design which has its own unique benefits. Intended to collect seismic data from the oceans, this ship has additional benefits like a large accommodation and deck area and massive fuel capacity in comparison to vessels of same length. The unusually large beam allows for greater stability and consequently a larger period making the ship a smoother sailing one. The large fuel capacity allows for long survey endurance lasting around 150 days.
The Flip Ship Research Ship
Created by the US Navy in 1962, the flip ship is designed like a spoon. Standing at 355 ft. The entire shift of the ship from its horizontal to vertical position takes around 28 minutes and it a sight worth beholding. Water is allowed to seep into ballast tanks, submersing the ship 300m into the water. This vertical stance enables the ship to carry out its purpose of being an accurate Research Ship.
