This tool assists maritime engineers and ship operators in determining the optimal timing for switching between different fuel types, typically heavy fuel oil (HFO) and marine gas oil (MGO), during vessel operation. It factors in parameters such as fuel viscosity, density, temperature, and flow rate, alongside engine specifications, to calculate the necessary lead time for a safe and efficient transition. For instance, considering the vessel’s fuel consumption rate and the volume of fuel in the service tank, the application computes the duration required to deplete the HFO and introduce MGO before entering Emission Control Areas (ECAs).
The implementation of such a calculation is critical for regulatory compliance, minimizing operational costs, and preventing potential engine damage. Historically, fuel changeovers relied heavily on manual calculations and estimations, increasing the risk of errors and non-compliance. These automated systems enhance precision and ensure adherence to environmental regulations, such as those stipulated by the International Maritime Organization (IMO), while also optimizing fuel consumption and reducing the likelihood of thermal shock or other adverse effects on the engine.
