Shore-side electricity can reduce in-port emissions

摘要

While docked at the port,ships shut off their propulsion engines,but they use their auxiliary engines to power refrigeration,lights,pumps and other equipment.These auxiliary engines are usually powered by high-sulphur marine heavy fuel oil(HFO),or in some cases by lower-sulphur marine gas oil(MGO),resulting in significant emissions of air pollutants,including sulphur dioxide(SO2),nitrogen oxides(NOx),particulates(PM),and volatile organic compounds(VOCs).
