The technology group Wärtsilä has been contracted to supply the engines and exhaust gas cleaning systems for a new 104m long exploration cruise vessel.
The ship is being built at the China Merchants Heavy Industry shipyard in China for Sunstone Ships of Miami, USA. There are options for an additional nine vessels.
The contract with Wärtsilä was placed by Ulstein Design and Solutions of Norway, the company responsible for delivering the design and equipment package to the yard. The order was booked in June 2017.
The supply comprises two 6-cylinder Wärtsilä 20 engines fitted with the Wärtsilä NOR exhaust gas cleaning system, and two 8-cylinder Wärtsilä 20 engines.
The Wärtsilä NOR is based on SCR (Selective Catalytic Reduction) technology. The system is compliant with various NOx (Nitrogen Oxides) emission reduction needs, such as the IMO Tier III rules.
The Wärtsilä equipment will be delivered to the yard in January 2018, and the ship is expected to begin operations in September 2019.
