^aIn the model, a 3% increase in fuel consumption is considered for the scrubber system: the use of a scrubber increases the energy consumption which is calculated to raise fuel consumption by 3% in case of seawater scrubber (open loop) and by 1% in case of freshwater scrubber (closed loop) (den Boer & Hoen, 2015). Therefore, for fuel consumption of main/auxiliary engine of scrubber (tons/hour), the following equation is used: [(fuel consumption of main/auxiliary of HFO) + (fuel consumption of main/auxiliary of HFO * (3%))]
