The use of LNG in the marine industry has been available for quite a few years and is known to be a popular and cleaner alternative to traditional marine fuel. However, it is quite complex to find a solution that suits the specific tank requirements on various LNG fuel tanks. One of the challenges in using LNG as fuel is storage. Type C tanks, which are designed to withstand cryogenic temperatures, are often considered a feasible option for LNG storage on marine vessels. Type C tanks, commonly 300-1000 m3, -162°C below 10 bar and less than 20 m in height are feasible to be used for LNG. Radar technology is ideal for this application since it has a vertical cold box with process connections on top of the tank. Solutions used for this applications must be IGF code compliant and approved by marine class societies.
