2. Inspecting fuel valve positions

• Ensure that the heating media is not turned on.

• Open the required fuel valves according to the PI diagram.

• Select MDO.

• Ensure that Seal Guard has a functional gas cartridge and oil.

• Activate the pump lubricator (Seal Guard) 24 hours before starting for the first time by turning the switch to 9.

• Not all pump models come with Seal Guard – if you are using one without Seal Guard, please go straight to Section 2.

1. Activating pump shaft seal lubrication (Seal Guard)

If Seal Guard is not activated in time, it may cause the pump shaft seals to leak.

There are also inlet and outlet valves on the outside of the unit.

Start-up and testing are done using MDO.

4. Inspecting instrument valves

• Open the air valves and ensure that there is adequate air pressure.

• Check the automatic filter air pressure gauge to see whether the air pressure rises to approximately 4 bar. (Note! Not all filter models come with a pressure gauge.)

3. Venting suction filters

• Open the venting screw (Figure 1) and ensure that the oil is flowing.

• The suction pressure gauge (Figure 2) should read > 0 bar (usually 0 –1 bar).

Figure 1 Figure 2

Remember to vent all suction filters and then close them after venting.

6. Starting feeder/supply pumps5. Activating fuses and thermal relays

• Ensure that the main switches are set to zero – otherwise, the cabinets will not open (1).

• Activate the electrical cabinet fuses (2) and thermal relays (3).

• Ensure that the drive switches are set to zero (4).

• Turn on the power with the main switch (5).

• Reset the alarms.

• Ensure that MDO is flowing into the pump (see Section 3).

• Test run the electric pumps. Ensure that the motors are rotating in the right direction. If the rotation direction is wrong, contact an electrician.

• If the rotation direction is right, leave one of the pumps running.

tEnsure that all drive switches are set to zero before switching on the main power.

After resetting, one of the alarms may still be active – this is normal. The lights should go off when the unit is started.

Ensure that the electric motor is rotating in the right direction (always clockwise).

Never run the pump ”dry”.

7. Venting the deaeration tank

A. Automatic venting

• Low level alarm sounds – venting starts.

• If you have this type of device, venting will run automatically.

B. Manual venting (pictured)

• Low level alarm sounds – the tank is vent by opening the valve.

• When the alarm shuts off, close the valve. (The deaeration tank may only be checked during the initial pump start-up.)

• Open all gauges by turning the yellow tip.

• The suction side pressure should drop to approx. 0 bar (Figure 1).

• The feed pressure should rise to 3 – 5 bar (Figure 2).

• If the connections are wrong, the feed pressure gauge (Figure 2) will not display any values.

8. Checking suction and feed pressure

Figure 2Figure 1

When manually venting the deaeration tank, the valve is opened only when the low level alarm sounds. Otherwise, the valve must stay closed.

Parallel feeder and booster pump pairs are connected from different cabinets.

One pump is in standby mode. Remember to test both pumps.

Never touch the pump relief valves! If necessary, pressure can be adjusted using the pressure regulator valve downstream from the pumps, not with the relief valves!

Page 7: Auramarine HFO Quick Start Guide

• Ensure that oil return circulation is allowed to the unit deaeration tank.

• Test run the electric pumps. Ensure that the motors are rotating in the right direction. If the rotation direction is wrong, contact an electrician.

• If the rotation directions are right, leave one of the pumps running.

9. Starting the booster/circulation pump 10. Checking booster/circulation and outlet pressure gauges

• Vent the unit’s external fuel system.

• The ship’s diesel engine fuel feed pressure should be the same as the unit’s outlet pressure.

• Also ensure that the fuel flow returns to the unit.

tEnsure that the electric motor is rotating in the right direction.

Never touch the pump relief valves! Outlet pressure is adjusted with the pressure regulator valve located outside the unit, not the pump relief valves!

Turn the switches for feeder and booster pumps being shut down to the standby position.

• Activate the viscometer on the control panel (1) and select Adjust viscosity (2). Also turn on the automatic filter (3).

• Check the display to ensure that the viscosity is 4 – 8 cSt.

Note! The display can also be placed outside the unit (engine control room).

• Ensure that the steam/thermal oil regulator valve is closed or the electric heaters are switched off.

• Ensure that the heat tracing valves are closed or electric tracing is shut off.

• If the regulator valve is open, contact an electrician, who will switch the feed phases.

• Temperature regulation is a safety function, which is only available with HFO.

11. Adjusting viscosity 12. Checking the steam/thermal oil regulator valve

14. Starting and running the engine on MDO

• Ensure that heat tracing is not on for unit outlet and inlet pipelines.

• Start the engine.

Ensure that heat tracing is not on for unit outlet and inlet pipelines.

13. Testing equipment and alarms

• Test equipment and alarms.

• Test functions according to the alarm panel; also test remote control.

• Also ensure that the alarms are being sent to the engine control room.

16 17

Page 10: Auramarine HFO Quick Start Guide

16. Switching to the use of MDO

• Turn off heat tracing for the unit’s outlet and inlet pipelines.

• Switch the change-over valve to MDO.

15. Switching to the use of HFO

• Open the valve for the unit’s external heat source.

• Open the valves (steam/thermal oil) for the heat exchanger in use. Use only one heat exchanger.

• Switch the change-over valve to HFO. The switch to HFO may take around 1 – 3 hours.

• Viscosity will be automatically set to the setpoint value. Check this value against the motor’s technical specifications (10–20 cSt). Regulation of the value may take several hours.

• Open the unit’s external fuel line heat tracing valves.

Be careful of hot surfaces – use protective safety gear.

A rise of more than 50°C in MDO temperature may damage the system.

The viscosity alarm monitors the setpoint. It is ± 3 cSt of the selected setpoint. The low viscosity alarm will be triggered when switching to HFO. This is normal. The oil temperature will rise to approx. 135 – 150°C.

18 19

Page 11: Auramarine HFO Quick Start Guide

17. Shutting down the system

• It is possible to shut down the ship’s diesel engine when viscosity decreases. The unit may also be shut down after this.

If the unit must be shut down when using HFO, turn on the unit’s heat tracing!

The system should always be shut down when using MDO – never HFO. Switching too quickly may damage the unit pumps.

Notes

Page 12: Auramarine HFO Quick Start Guide

PumpsThe pumps are equipped with mechanical shaft seals. The mechanical seals must leak to operate properly. The mechanical seals consist of two highly polished, very flat surfaces. The surfaces may not run dry, as they will otherwise fail very quickly. Therefore, they are designed to allow a very thin film of liquid to exist between them. Some of the liquid will leak out of the seal. When pumping HFO, the leaking HFO will visibly accumulate on the pump. This is normal and does not indicate

a manufacturing defect. It is not a guarantee issue.

A leakage rate of 10 drops of oil per hour or less is considered normal. Please note that seals will sometimes require a “run in” period, with leakage gradually diminishing over several hours of operation after the initial start-up.

Start-ups can be particularly hard on mechanical seals. Never start a pump without priming. Always make sure that the Seal Guard lubricator is activated, if the pump is equipped with one.

Automatic filterDuring the initial start-up of the fuel system, the automatic filter may get clogged. This does not indicate a defect in the automatic filter. The tanks and pipes of the fuel oil system contain a lot of dirt and debris. The automatic filter will catch the dirt, but there may be so much of it that the filter cannot clean itself anymore. The clogging of the filter will also depend on the quality of the oil. Poor quality oil contains particles, tar, paraffin and

IMPORTANT POINTS TO REMEMBER – PLEASE READ!

other impurities, and tends to clog the filter elements. As a result, the automatic filter will need to be stripped and the filter elements cleaned, in some cases repeatedly. When the dirt has been flushed from the system, the automatic filter will operate normally. This is all normal and not a guarantee issue.

ViscometerDuring the initial start-up of the fuel oil unit, the viscometer may indicate an unexpected viscosity. Should this happen, the value will tend to be too high. This is typically caused by a dirty sensor, i.e. the pendulum. Poor quality oil will worsen this, thus requiring a cleaning of the pendulum. Flush the pendulum with diesel oil or a mild detergent. Be extremely careful when handling the pendulum, as it is a sophisticated instrument.

GuaranteeAlthough all Auramarine fuel booster unit contracts offer a guarantee of quality, normal wear parts are not included in the guarantee. The following are considered wear parts:• Mechanical shaft seals of the pumps• All gaskets, rubber pistons and o-rings• Filter candles and elements• Couplings and coupling elements• Ball bearings for pumps and electric motors
