Increased focus on the environmental impact from the marine industry has led to a general increased focus on regulations related to emissions from several places on the ship.
In an effort to reduce Sulphur pollution, the International Maritime Organization has agreed that ships’ fuel must be limited to a maximum of 0.5 percent sulphur in the fuel as of January 1st 2020, globally. As consequence, decisions on how to comply with this limit must be considered.
There are overall three methods as for staying in compliance with the regulation. The ship can either sail on the more expensive low sulphur fuel oil (LFO), it can have engines running on alternative fuels such as natural gas installed, or an exhaust gas cleaning system scrubber can be installed to wash out particles and sulphur.
The scrubber solution enables the possibility of using the cheaper high sulphur fuel oil (HFO), which makes it an attractive solution for compliance. Using the scrubber solution requires monitoring of the exhaust, to ensure that the sulphur emission limit is held and that the scrubber is working, as well as monitoring the washwater discharged from the scrubber, which also must be within limits on certain parameters (pH, PAH and turbidity).
Danfoss IXA is one solution provider of emissions monitoring solutions, providing measurement and documentation of compliance of emissions of the ship.
Visit stand 1877 at this coming Seatrade Cruise Global event 9-11 April 2019 at the Miami Beach Convention Center and learn more about our marine emission sensors and our newly launched washwater monitoring system that will help you document your compliance with the 2020 global sulphur regulation.
