Norwegian Cruise Line announced today the completion of the retrofitting of a new exhaust scrubber system on Norwegian Jewel, aimed at reducing air emissions.

Norwegian Jewel’s new lightweight in-line scrubbers are a hybrid technology developed by Yara Marine Technologies that are able to operate in Dry mode, Open loop and Closed loop, said the company in a statement.  Five scrubbers were installed, one per engine, covering the whole propulsion system.

“Collectively, they are capable of reducing the emission of sulfur to air up to 99 percent and also reduce 85 percent particulate emission to the air,” said Norwegian.

“Norwegian is firmly dedicated to upholding the highest standards of excellence in environmental protection practices, as well as leading the industry in seeking out technology that makes our ships not only an enjoyable vacation experience, but also ensures that we continuously protect the environment that our guests love to explore,” said Robin Lindsay, Executive Vice President of Vessel Operations for Norwegian Cruise Line Holdings.

Norwegian is the first cruise line to install scrubbers with a state-of-the-art water membranes filtration unit. This sophisticated water cleaning system uses Ultrafiltration technology to clean the recirculated water during the closed loop operation down to clear water.  The by-product is collected and removed in drums.
