Wärtsilä Hamworthy has signed a deal with German shipbuilder Meyer Werft for the delivery of hybrid scrubbers for Royal Caribbean’s (RCL) new Sunshine Class ships.
Under the deal, Wärtsilä Hamworthy will provide four hybrid scrubber systems for the two vessels being built at Meyer Weft’s shipyard in Papenburg, Germany.
Installation of the scrubbers will help remove sulphur emissions and harmful particulates from the vessel’s exhaust, making them compatible with the 2015 emission control area (ECA) 0.1% sulphur limit, the worldwide 0.5% limit from 2020 and the upcoming North American ECA.
The company said that the hybrid approach enables switching between open-loop and closed-loop scrubbing, which will allow vessels to perform scrubbing operations with sea water. In the ports the system can be closed, re-circulating the water already within the scrubber.
RCL ordered the first cruise ship in February 2011 and the second vessel in the first quarter of this 2012, both of which will join the company’s fleet as a new class of ships under Project Sunshine.
The 158,000gt vessels will be capable of carrying around 4,100 passengers, and will be equipped with the latest energy efficiency and environmental technologies, in addition to redesigned spaces to optimise capacity and fuel use.
The first vessel is scheduled to be delivered from Meyer Werft’s Papenburg shipyard to RCL in autumn 2014, while the second will be delivered in spring 2015.
