🔍 Key Concepts

• Viscosity control in a heavy fuel oil (HFO) system • Role of final heaters versus day tank heating in preparing fuel for injection • What the viscosimeter symbol V is connected to in the piping diagram

💭 Think About

• Trace the fuel flow from the purifiers through the final heaters, viscosimeter, and into the main engine. Which component must be adjusted to keep viscosity at the correct value at the engines? • Ask yourself: does viscosity need to control how much fuel is pumped, or how hot the fuel is before it reaches the injection pumps? • Look at where the control valve marked near the heaters is located. Is it on a steam line or a fuel line, and what does that suggest the viscosimeter is modulating?

✅ Before You Answer

• Confirm that the viscosimeter V is located after the final heaters and filters, but before the injection pumps. • Identify which line has a control valve labeled near the heaters – is it the steam supply to the heaters or the fuel delivery line? • Decide whether viscosity is normally adjusted by changing temperature (via steam to heaters) or by changing pump output or metering.
