Wartsila has been contracted to supply the engines and exhaust gas cleaning system for a new 104-metre-long exploration cruise vessel.

The ship is being built at the China Merchants Heavy Industry (Jiangsu) Co shipyard in China for Miami-based Sunstone Ships Inc. There are options for an additional nine vessels.

The contract with Wartsila 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 full Wartsila scope of supply comprises two six-cylinder Wartsila 20 engines fitted with the Wartsila NOR (NOx Reducer) exhaust gas cleaning system, and two eight-cylinder Wartsila 20 engines. The Wartsila NOR is based on selective catalytic reduction (SCR) technology. The system is said to be compliant with various nitrogen oxide emission reduction needs, such as the IMO Tier III rules.

"We are delighted to be cooperating with the Ulstein company in this newbuild project. The Wartsila 20 engine is a very good product fit for this vessel, while the NOR system is optimised and validated for all our medium speed engines in terms of reliability, flexibility and size," said Cato Espero, Sales Director, Wartsila Norway.

"Reliability and performance are important criteria for cruise vessels since they are mostly operating to strict schedules. At the same time, environmental sustainability is today an essential element in the cruise sector. Wartsila's reputation speaks for itself in all these areas," remarked Ove Dimmen, Sales manager, Ulstein Design & Solutions AS.

The Wartsila equipment is due to be delivered to the yard in January 2018, and the ship is expected to begin operations in September 2019.
