Taking Nitrogen Out of the Equation
The Boil-Off Gas (BoG)contains significant non-greenhouse gas nitrogen (N2). IMO allows ship owners to deduct nitrogen consumption from the reported fuel mix. As nitrogen evaporates first, even a small amount in LNG can contribute to a substantial portion (up to 10-15%) of nitrogen in the vessel's fuel. BoG nitrogen consumption varies based on factors like LNG quality, voyage length, vessel speed, weather conditions, and equipment status. Continuous measurement of BoG streamlines documentation for IMO and charterers, offering ship owners a strategic advantage. Accurate BoG measurement is crucial for validating improved Carbon Intensity Indicator (CII) claims, making continuous measurement the most effective way to calculate nitrogen consumed as fuel.
