LNG Carriers utilize boil-off gas (BoG) from the cargo as fuel. The BoG composition varies with LNG cargo and also changes during a voyage. Being able to measure the composition of the BoG is of importance for the shipowner/charterer, since it is used to calculate the fuel value of the fuel consumed from the cargo. In addition, knowing the composition of the fuel can be used to optimize engine performance.
Solution
Tunable's natural gas analyser is designed for accurate and continuous gas analysis with gas composition data fed directly into the power management system. The instrument identifies the amount of all major hydrocarbons (C1 to C5) and calculates the calorific value and methane number. The data is streamed continuously. Condition monitoring and upgrades can be done remotely via a datalink.
