The technology group Wärtsilä will supply Hybrid Scrubber system packages, specially customised to meet the specific needs of two cruise vessels. The ships are owned and operated by Norwegian Cruise Line (NCL).
The 325m Norwegian Breakaway and Norwegian Getaway 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).
The legislation became effective in January 2020. Customization of the system was required in order to meet the ships’ restricted space availability.
“Wärtsilä’s technical and engineering capabilities are once again emphasised with this tailor-made exhaust gas cleaning solution. 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,” says Sigurd Jenssen, Director,
The Wärtsilä 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.
The Wärtsilä equipment is scheduled for delivery in the first half of 2020. For the past seven years, Wärtsilä has had an engine maintenance agreement with NCL, and four new NCL cruise ships, currently under construction, will be fitted with Wärtsilä engines and scrubber systems.
