2. Background
IMO have ratified 200 NM of the North American coastline as a SECA area by the Aug. 2012 – 0.1% Sulphur effective from January 1 st 2015 4

3. Process of HFO/MGO change over
1. Regulate the index of engine, around 25~40%.
2. Shut off steam tracing & steam to pre-heater.
3. Monitor viscosity: 2 cSt ~ 20 cSt.
4. ViscoSense (4~20mA) signal input the control box of DMA cooling system.
5. Start DMA cooling system, the chilled water is available in stand-by.
6. Initiate the change-over on touch screen from HFO to MGO.
Then the MGO will add into circulating line gradually.
7. The rate of temperature drop of fuel inlet to the circulating line is controlled to not exceed 2 ℃ per minute.
8. MGO cooler is ready to cool the fuel oil per the viscosity of fuel oil in circulating line.

4. Principle of MGO Cooler System
Basing on P&ID, the line, whereas the
3-way Valve
is installed in the cooling water
Temperature Sensor
is mounted at the
Plate Heat Exchanger
oil outlet.
The temperature of fuel outlet will be controlled by the
Controller
