Reference Answer
### Objective of Fuel Treatment
The primary objective of treating heavy fuel oil (HFO) on board a ship is to remove harmful impurities and condition the fuel to a state suitable for injection into the main or auxiliary engines. This process is critical to prevent damage to expensive engine components, ensure efficient combustion, and comply with environmental regulations.
The key goals are:
1. **Removal of Water:** To eliminate both free and emulsified water, which can cause poor combustion, corrosion of fuel system components, and reduce the fuel's calorific value.
