Conventional LNG

Despite the fact that liquified natural gas (LNG) has been on the market for several years as an alternative fuel option, there are many technology choices that need to be made depending on specific vessel design and operational requirements.

One of the biggest challenges for LNG-fueled vessels is finding the most efficient use of a vessel’s available space for the fuel tank and the associated systems. LNG storage on board requires more space than conventional fuel oil storage. This is primarily because LNG has a lower energy density than fuel oil, and therefore requires a larger tank to provide the same operational range. In addition, due to the low temperature of LNG, the tank insulation and the required gas handling systems, additional space is needed.
