Estimating and calculating the speed, power and fuel consumption of LNG carriers

As seaborne trade is an international business and its economic structure is highly complex, it is rather demanding to produce forecasts and estimates of the maritime shipping market. However, these tools are considered necessary to assist in making decisions influencing the performance of the shipping business in future. There are a number of elements affecting both the cost and the safety of transporting energy-generating products by sea. They include the ship's size and price, consumption and price of fuel, the ship's daily fuel consumption, crew wages, costs of maintenance of the ship and her equipment, etc. Hence it is necessary to know the main features of a vessel. This paper presents the main characteristics of two different designs of ships built for transporting liquefied natural gas (LNG) – Moss type LNG carrier and SPB type LNG carrier – providing the estimation of their speed, power and fuel consumption over a one-year period, including the monthly breakdown, which is of great importance given the climate conditions in which these carriers may operate.
