The CE Delft report and its findings follow two additional studies released in 2019 which were conducted to further understand the impact of EGCS on marine environments. This includes a two-year study conducted by DNV GL, which found washwater samples from 53 cruise ships equipped with EGCS to be below the limits set by major international water quality standards. Another recent study, conducted by the Japanese Ministry of Land, Infrastructure, Transport and Tourism, found the impact of scrubbers on water quality and marine life to be negligible.
Taken together, the association asserts that these studies further support the use of EGCS technology as a viable means for compliance with the IMO’s 2020 sulphur requirements, which went into effect 1 January 2020 and mandate that emissions from maritime vessels do not exceed 0.5% sulphur content, compared to 3.5% previously.
Additional means of compliance with IMO’s 2020 regulations include the use of LNG fuel, which has virtually zero sulphur emissions, and use of compliant fuel such as Marine Gas Oil. The CLIA ocean-going cruise fleet includes two ships that are currently using LNG for primary propulsion, with another 25 under construction or on order.
