Liquified natural gas is cooled natural gas at an extreme low temperature of -161 C which drives it to transform from gas to liquid. It is transported to a chosen destination in special LNG tankers and due to its liquid form, the transport is much more profitable. The LNG market is continually growing and evolving, which is confirmed by the trends seen in the supply and demand for LNG. The number of countries which export and import LNG and the amount of LNG trade is growing year after year. On the other hand, in the last few years the price of LNG has been very volatile due to the strained relationship between Europe and Russia and the consequences of the global COVID-19 pandemic. The LNG fleet has been following the trends of the LNG market. Due to the growth of demand, in the recent years fleet capacity of newer vessels is larger than in the previous years and the propulsions system have been modernized and made more efficient. The LNG supply chains complexity has been substantially increasing and it is becoming more disintegrated which allows for more flexibility and better contract conditions. On the other side, the ratio of spot and short-term contracts in the overall LNG trade has also been increasing, even though short-term prices are higher than the one determined by long-term contracts.
