A 341-foot (104m) exploration cruise vessel being built for Sunstone Ships Inc. of Miami, Florida, will be equipped with Wärtsilä engines and exhaust gas cleaning systems, according to the Finland-based global technology group. The contract was placed by Ulstein Design and Solutions of Norway, the company responsible for delivering the design and equipment package to the shipyard in Jiangsu, China.
The ship will be outfitted with two 6-cylinder Wärtsilä 20 engines fitted with the Wärtsilä NOR (NOx Reducer) exhaust gas cleaning system, and two 8-cylinder Wärtsilä 20 engines. The NOR system is based on selective catalytic reduction technology and is compliant with various NOx (nitrogen oxide) emission reduction requirements, such as the IMO Tier III rules.
“The Wärtsilä 20 engine is a very good product fit for this vessel, while the NOR system is optimized and validated for all our medium-speed engines in terms of reliability, flexibility and size,” Cato Esperø, Wärtsilä sales director, said in a company statement.
