7 Enhanced Fuel Switch Module (EFS) Fuel switch not standardized on most ships SECA compliance requires fuel switch from HFO to MGO SECA fuel switch could cause loss of propulsion power if the fuel supply system is not optimized. < 7 >

9 Enhanced Fuel Switch Module (EFS) Fuel switch HFO to MGO Standard - Switch over time depending on: Total volume of fuel system (booster circuit) Fuel consumption of running engine(s) during switch over Sulfur content of HFO and MDO EFS - Negligible parameters: Total volume of fuel system (booster circuit) Switch over time vs. Sulfur content Sulfur [wt.%], time [sec] 3 2,5 2 1,5 1 0,5 0 Standard EFS Fuel consumption of running engine(s) during switch over Sulfur content of HFO and MDO (as long as <0.1%S) EFS switch time Standard switch time Max. change in temperature 2K/min, Viscosity between 2-14 cst < 9 >

10 Enhanced Fuel Switch Module (EFS) Safe (Sox compliance) and beneficial fuel switch is possible! EFS by MAN 1. Lower OPEX due to lower MGO consumption at fuel switch 2. Fully automated system 3. Less documentation for IMO inspection 4. Defined switch over time 5. Reliable and safe vessel operation Enhanced Fuel Switch Module (EFS) by MAN available now for a safer fuel switch < 10 >
