RPM & Fuel Monitoring System

With this array of Flow meters in place, the rest of the work is done within the system to do the calculations to give a better picture of the fuel usage while the vessel is on voyage, thus reducing the need for the vessel operators to be physically present to curb pilfering of fuel. This system allows the crew to see the bunkering of the fuel which is F1 while the rest of the reading (F2 F4) will be sent to the operators and vessel managers via system.

The FM3 placed strategically between the outlet of day tank and before the manifold gives the actual amount of usage on the main engines as well as the generator sets. While this is being done there is always a certain amount of unused fuel that returns back to the day tank. This reading is captured onto the FM4.

The FM2 measures the amount of fuel that flows into the day tank which is required for usage for the day. The amount of fuel required is normally determined by the chief engineer and the sometimes the vessel manager (based on the voyage requirements).

The FM1 measures the fuel that is bunkered into the vessel. The system displays the mass, temperature, volume and density. With the help of the display, the total fuel bunkered and the quality of the fuel (using the density function) can be analyzed real-time.

The fuel monitoring systems primary function of to ease the Vessel Managers work. Automating the system reduces human interferences thus increasing the accuracy. The primary components used will be Mass Flow meters with an accuracy level of 0.5%. These flow meters are used as an array to monitor the total incoming fuel (FM1), fuel used on a day to day basis (FM2- fuel to day tank), fuel from the day tank that flows into the main engines and the generator sets (FM3) as well as the calculating the unused fuel that flows back through the return lines (FM4).
