LNG ships are specialized modes of transportation of natural gas as cargo, which by its very delicate nature of being carried in cryogenic liquid form, dictates efficient and safe cargo management on-board. LNG cargo, due to its volatility and special nature, is affected greatly by temperature and movement, causing continuous boil-off. This means the boil-off needs to be continuously dealt with on-board. Traditionally it has been burnt off in the main boiler used for propulsi

With sensor information on board LNG vessels and enrichment using the laws of physics and mathematics, companies have developed the technology to precisely ascertain the real time rate of boil-off on an LNG vessel at any instant and in any situation that the vessel finds itself. The LNG rate of boil-off is not an unknown entity as such, as it can be calculated in test conditions in a laboratory. This has however not until recently been attempted on board in a scientific manne
