More than 60 % of new orders at Korean shipyards have been for ships fitted with scrubbers , exhaust cleaning systems that meet international standards for sulphur emissions , compared to just 25 % of orders in 2017 and 2018 . Even large companies that said they had opted for low sulphur fuel were considering scrubbers , said Korean Register senior editor Yong - Tae Kim . “If they had a lot of trouble in the operation of scrubber they would not extend the installation of scrubbers to the rest of their fleet.” There are uncertainties over the price difference between low and high sulfur fuels and an international standard for low sulfur was not expected before 2022 , he said .
