  3. 1. DMA Introduction • DM Alscott • Factory established in 2003 • JV established in 2008 Together, we do more.

  4. 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 1st 2015

  5. 2. Background

  6. 3. Process of HFO/MGO change over Change-over valve Preferential position for Cooler Optional position for Cooler

  7. 3. Process of HFO/MGO change over • Regulate the index of engine, around 25~40%. • Shut off steam tracing & steam to pre-heater. • Monitor viscosity: 2 cSt ~ 20 cSt. • 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.

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