Project Backgroud

International Maritime Organization (IMO) has set the maximum allowable content of sulfur in fuel used by ships through MARPOL73/78 ‘International Convention for the Prevention of Pollution from Ships’ that entered into force in 2005. All ships operating in SECA (Sulfur Emission Control Area) have been required to use fuel with the sulfur content of 1% or less since July 2010 and to use fuel with the sulfur content of 0.1% or less since 2015. In addition, regulatory requirement of using fuels with the sulfur content of 0.5% or less in all oceans throughout the world is to take effect in 2020.
To meet the requirements on the permitted sulfur levels in ships’ fuels, ships must use fuels with low sulfur content or be equipped with the desulfurization system equivalent to meet IMO, MARPOL 73/78 regulations.
