According to Wärtsilä, the scrubber systems have been "specially customised to meet the specific needs’ of the two cruise ships – which included adapting ‘to meet the ships’ restricted space availability".
The 325 metres long ‘Norwegian Breakaway’ and ‘Norwegian Getaway’ vessels will be fitted with Wärtsilä scrubber systems, enabling them to be in compliance with the International Maritime Organization’s (IMO) sulphur restriction legislation while operating on heavy fuel oil (HFO).
"Obviously not all installations are the same and there is no single system that fits all applications. Having the flexibility to adjust the design to meet the customer’s specific needs is an important value-adding feature of our offering," commented Sigurd Jenssen, Director, Exhaust Gas Cleaning, Wärtsilä Marine.
The Wartsila hybrid solution allows flexibility in the cleaning of sulphur from the exhaust gases. When operating in closed-loop mode, the wash water circulates from the scrubber unit to a process tank, with seawater being used as make-up replenishment water as needed.
