Clean Marine provides high-quality exhaust gas cleaning systems for all vessel types, enabling shipowners to comply with international emission control regulations in a cost-effective way.
The IMO’s Sulphur 2020 cap is leading to changes in global maritime fuel consumption. Prior to 1 January 2020, ships ran primarily on high-sulphur fuel oil (HSFO). HSFO emissions contain toxic levels of sulphur oxides (SOₓ). Emissions of SOₓ, NOₓ and particulate matter lead to 50 000 premature deaths a year in Europe alone. SOₓ emissions also cause acid rain.
IMO compliance can be achieved by switching to very low sulphur fuel oils (VLSFO), or to continue burning HSFO by installing a certified scrubber – called an exhaust gas cleaning system (EGCS).
There are many uncertainties linked to burning VLSFO, the most common being availability, compatibility, high prices and risk of engine failure.
Although scrubbers are highly effective, installation has been time-consuming and costly, as modifications to the vessel may be needed to compensate for the added weight. In some coastal areas, open-loop scrubbers – scrubbers that release clean gas into the air and wash water into the sea – are prohibited due to concerns about the impact on the marine environment of effluent water discharge.
Due to improvements in scrubber technology and an increase in the price spread between high and low sulphur fuels, Clean Marine scrubbers are a cost-effective solution for complying with IMO regulations. The company’s new-generation scrubbers feature real advances, with a 40 per cent shorter installation time and no need for vessel modification.
Clean Marine’s hybrid EGCS units switch seamlessly between open and closed-loop modes, allowing flexibility in and out of emission control areas. When used in open-loop mode, vessels can transition between high and low alkalinity and salinity water without loss of SOₓ cleaning efficiency. Before being discharged, wash water is closely monitored and treated to exceed the strict limits set by the IMO.
Installation of a Clean Marine scrubber enables ships to run on standard fuels while capturing SOₓ emissions. Depending on fuel price spread, fuel consumption and other factors, the return on investment ranges between just six and 18 months.
Clean Marine offers the only open-loop EGCS which complies with Clean Design – DNV GL’s most stringent Environmental Class notation. This ensures that ships equipped with Clean Marine scrubbers are prepared to meet future emissions reduction targets.
Approximately 3 500 vessels were fitted with scrubbers in time to meet the 2020 cap. The International Energy Agency estimates that about 5 200 vessels will have scrubbers fitted by 2024.
Clean Marine is a market leader in EGCS technology, with offices in Bulgaria, China, Norway, Singapore and the US, and service hubs in all major ports worldwide.
Clean Marine is participating in the pioneering DeCarbonICE research project on carbon capture and storage on board ships. The new solution will use a cryogenic process to turn captured CO₂ and other GHGs into dry ice for storage.
