Handling Cold vs. Saturated LNG

Since 1941, when the first pilot LNG liquefaction plant was set up in Cleveland, US, the LNG industry has amassed a huge body of experience that has enabled the near perfect public safety record that it has earned. Today, the global LNG supply capacity has grown to more than 240 million tpy, with over 430 LNG carriers in operation, with a projected growth to approximately 350 million tpy by 2020.

In those early days of the industry, equipment was not available for handling LNG, so a new special equipment industry was born. These developments largely originated from the experience of a group of scientists and engineers based at California Institute of Technology (Caltech), who were involved with the early US aerospace industry.
The LNG supply chain has been growing ever since with the latest new market segments being the small scale LNG plant and LNG as a transport fuel [Figure 1]. These developments have resulted in the introduction of new technologies and solutions over the traditional large scale LNG approach.
