Abstract
According to the new regulations of the International Maritime Organization (IMO), starting from January 1, 2020, large ocean shipping vessels (types of ships used to transport goods through the oceans) must use use low-sulfur fuel, only 0.5% such as MGO (marine gasoil) or ULSFO (ultra-low sulfur fuel oil) to replace heavy oil with sulfur content 3.5% (or the rest of the bunker oil) is being widely used today. This transformation aims to cut sulfur-dioxide emissions (SO2) in shipping operations. Currently, the global shipping industry accounts for 13% of global SO2 emissions every year. If not converted to clean fuels with low sulfur content, air pollution due to SO2 toxic gas from shipping vessels will increase 570,000 premature deaths worldwide in the period 2020-2025. The new IMO regulation will affect at least 60,000 ocean freight vessels and make the shipping industry cost $ 50 billion more annually. This cost burden led to warnings and noisy arguments about the quality and availability of new fuels as well as calls to delay implementation of the new IMO regulations.
