As the name suggests, semi-submersible barges have a capacity of going on a lower floor the free water go up to a considerable extent. This is achieved by the presence of ballast tanks. These ballast tanks when filled with water lower the barges into water. On pumping out the water, the irrepressibility of the vessel increases and the overall structure lifts to a higher place water. This kind of tractableness has led to semi-subs being used in various applications.
The imagination of semi submersibles has had takers from different fields. Semi-Submersibles have been used by the touristry industry to showcase the under-sea surface world to tourist. This usage goon is pretty limited. Major applications of the semi-submersibles have been in offshore drilling, under sea exploration and heavy lift applications. A quite unique application of the concept of semi-submersible vessels has come up in the field of drug trafficking, where Coast gaurds have nabbed semi-submersible vessels carrying drugs being import in international waters.
We shall study each of the application in details and the reason for the suitability of semi-submersibles in each case

Semi-Submersible Basics
fit in to the definition of the term Semi-Submersible, as provided by Schlumberger Inc.
A grouchy type of floating vessel that is supported primarily on large pontoon-like structures submerged below the sea surface. The operating decks be elevated perhaps 100 or more feet above the pontoons on large steel columns. This design has the advantage of absorption most of the argona of components in contact with the sea and minimizing despatch from waves and wind. Semisubmersibles can operate in a wide barf of water depths, including deep water. They are usually anchored with six to xii anchors tethered by strong chains and wire cables, which are computer controlled to maintain stationkeeping. Semisubmersibles (called semisubs or simply semis) can be used for drilling, workover operations,...If you want to get a full essay, outrank it on our website: Orderessay
