Heavy Fuel Oil (HFO)

The generic term heavy fuel oil (HFO) describes fuels used to generate motion and/or fuels to generate heat that have a particularly high viscosity and density. In the MARPOL Marine Convention of 1973, heavy fuel oil is defined either by a density of greater than 900 kg/m³ at 15°C or a kinematic viscosity of more than 180 mm²/s at 50°C. [...]
