Chapter 4 – LNG Carrier

An LNG carrier, or LNG ship, is a tank ship designed for transporting liquefied natural gas (LNG) under the temperature of −162 °C. It is a product that is internationally known by its high technology, high difficulty, and high value. It has the honor of being called “the crown jewel,” and only 13 shipyards in the world are capable to build this LNG carrier. LNG carriers provide the link in the LNG chain between where the natural gas is liquefied and where it can be turned into gas, and enable large amounts of clean natural gas energy to be transported to the consumer, large distances from the LNG liquefaction plant. This chapter is meant to provide information about the LNG ships such as its cargo cycle, containment systems, structural design, and different maintenance checks needed.
