Four-scrubber retrofit for cruise ship

The scrubbers will replace the silencers of the ship’s four 8MW engines, which Green Tech says makes it the largest marine scrubber installation to date. The hybrid scrubber system will operate in both open loop and closed loop modes, while the compact dimensions are said to avoid sacrificing any accommodation space. The equipment will be delivered in March 2013, for installation during a scheduled drydocking at the Pearl Harbor Naval shipyard.

“The contract is another important step towards convincing ship owners that exhaust gas cleaning systems is a feasible and less expensive alternative to running on low sulphur fuel,” says Peter Strandberg, president and CEO of Green Tech Marine. He adds that the system’s other benefits include reduced PM emission, compared with the MDO alternative.
