Wartsila will retrofit its Open Loop Scrubber systems on three additional vessels
Wärtsilä has been contracted to retrofit itsOpen Loop Scrubber systems on three additional vessels owned by Color Line, Norway's largest cruise and ferry operator.
The new contract covers the company's SuperSpeed I, Color Magic and Color Fantasy ships. SuperSpeed I sails between Norway and Denmark, while the other two vessels link Oslo, Norway with Kiel, Germany.
Each vessel will be fitted with four systems designed to rid the ships' exhaust gases of harmful sulphur oxide (SOx) and particulate emissions. The Wärtsilä systems will enable the vessels to comply with current and anticipated environmental legislation, and to operate without restrictions in Emissions Control Areas (ECAs).
The system operates in an open loop using seawater to remove SOx from the exhaust. Exhaust gas enters the system and is sprayed with seawater in three different stages. The sulphur oxides in the exhaust react with the water to form sulphuric acid. Chemicals are not required since the natural alkalinity of seawater neutralizes the acid.
Wash water from the system is treated and monitored at the inlet and outlet to ensure that it conforms to all applicable discharge criteria. It can then be discharged into the sea with no risk of harm to the environment.
