Your assignment is to prepare and submit a paper on ship and cargo types. Gas cargo is one of the most prevalent types of cargo to be seen in the oceans of the world and it is not only because of its unusual nature but also as a result of the uniqueness of how it is transported. The difficulty in the transportation of gas is that in its natural state, it does not have the properties that other liquid gases, such as crude oil, tend to have. This is because in its natural state, it is in gaseous form and this creates a situation where it cannot be transported in that state (Energy Information Administration, 2003). Therefore, in order to ensure that its transportation is easier, this commodity has to be converted into a more manageable state through cooling and pressurisation so that it can take on a liquid form. The liquefaction of gas ensures that its volume is reduced an estimated six hundred times and this makes it possible for it to be transported by ship. This presents a challenge for regular ships and it creates a situation where specialised ships are designed specifically for the purpose of transporting gas. The ships that are designed to transport gas are designed in such a manner that they have powerful cooling and transportation systems that are meant to ensure that the gas remains in a liquid state throughout the journey. It is essential to note that this type of cargo is highly delicate and it has to be maintained in a liquid state at all times to make it possible for its transportation to be easier. Therefore, gas carriers are often considered to be among the most specialised of ships of a commercial nature mainly because their capacity to carry the gas cargo means that they have to have some of the most expensive equipment in the business. As a result, gas carriers cost almost twice more than regular oil tankers of similar sizes and this is a testament to its highly specialised nature. In most cases, the gas cargo itself tends to consist of propane or methane and these are normally used as .alternatives to other carbon fuels because of their essentially environmentally friendly nature. .
