Some owners are already investing in them, but there are still doubts about the readiness of such systems.
A study from the International Maritime Organization (IMO) says the installation of scrubbers is likely to accelerate in the second half of 2018 to meet the low-sulphur fuel deadline. It expects about 3,800 ships to have them fitted by 2020.
Many shipping companies are already making the move to use scrubbers due to sulphur restrictions in the emission control areas (ECAs) of North America and Europe.
