Cruise Company, Norwegian Cruise Line has announced that two more ships in its fleet are now retrofitted with a new exhaust gas cleaning system (EGCS): Norwegian Sun and Norwegian Jade.

The technology also called scrubbers, is used to remove sulfur dioxide from a ship's engine exhaust, allowing ships to use lower-cost fuel with a high sulfur content and still meet international anti-pollution regulations.

In 2014, Norwegian Cruise Line was the first cruise company to announce its plans to retrofit six vessels with EGCS and has boosted that commitment with additional two vessels making it eight ships now. In conjunction with the line's Sail & Sustain environmental program, the new systems are aimed at significantly reducing air emissions and, subsequently, the ships' environmental footprints.

The company said that in each ship, 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.

Norwegian Jade and Norwegian Sun’s new technology will reduce the equivalent of around 3,000 tons of sulfur oxide (SOx) gas in the years to come, NCL added.

Yara Marine Technologies developed the lightweight hybrid technology in-line scrubbers which are able to operate in open loop, closed loop and closed loop with bleed off mode.

Norwegian eight ships with scrubbers are Norwegian Jade, Norwegian Sun, Norwegian Pearl, Norwegian Gem, Norwegian Escape, Norwegian Joy, Pride of America and the company’s newest ship sailing in June 2018, Norwegian Bliss.

The company led the industry by being the first cruise line to install scrubbers with a state-of-the-art water membranes filtration unit in 2016. 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. 

Norwegian Cruise Line said it is on track to meet its goal under the MARPOL Annex VI regulations of reducing its global sulfur cap from 3.5 percent to 0.5 percent by 2020.
