World's biggest scrubber system sets sail
On a sunny day in the German harbor-town of Hamburg, M/V Norwegian Escape, a brand new cruise ship, sets sail for the first time. On board are five Yara SOx scrubbers – one for each engine. The scrubbers ensure that the cruise is not just pleasurable, but also environmental friendly.
Yara Marine Technologies has developed a simple and cost-efficient solution to fight air pollution at sea: the inline scrubber. An inline scrubber is basically a “gas washing machine.” A simple cylinder that replaces the silencer of a ship engine and cleans the exhaust gas, reducing SOx emissions by up to 99%.
To make her voyages from Miami (U.S.) to the Caribbean and beyond as environmental-friendly as possible, the owners of the Norwegian Escape teamed up with Oslo-based Yara Marine Technology to install the world’s biggest marine SOx scrubber system, with a capacity to clean emissions from 76.8 MW engine power. She has of course also additional environment protection systems onboard for other pollutants (e.g. ballast- waste- and bilge water).
M/V Norwegian Escape is the newest fleet member of one of the world’s largest cruise ship operators: Norwegian Cruise Line. She can carry up to 4,248 passengers and 1,731 crew- members. Diesel consumption at full cruising load is about 11 tons per hour, fueling an engine capacity equivalent to about 1,000 cars.
About Yara Marine Technologies
Yara Marine Technologies (former Green Tech Marine) supply small, lightweight in-line scrubbers, replacing existing silencer, able to operate in Dry mode, Open loop and Closed loop as per customer requirements. Thanks to our scrubber’s small footprint and low weight, Green Tech Marine® scrubbers are suitable for virtually any kind of vessel, whether it is a new build or a retrofit.
The scrubbers can be custom-made for any engine size, both 2-stroke and 4-stroke engines. The scrubber requires about the same space as the silencer it is replacing. When operating in closed loop. The Green Tech Marine® scrubber applies harmless Magnesium Oxide as alkali additive, in lieu of the hazardous Caustic Soda - Safety is always our top priority.
