Cruise ships to feature laser emissions monitoring

Mitsubishi Heavy Industries (MHI) in Japan is to install Emsys laser emissions monitoring equipment from WR Systems onboard two newbuild vessels under construction for Carnival cruise line’s AIDA Cruise brand.

The continuous emissions monitoring system to be implemented on the two 125,000-ton passenger vessels, the largest ever constructed for AIDA Cruises, will feature laser-based emissions sensors, allowing measurement of up to 10 exhaust stacks.

The system also has the capability to measure smoke (opacity) and particulate matter (PM). The standard configuration measures NOx, SOx and CO2, and has been awarded type approval by ABS.

WRSystems says it can also be configured to report carbon monoxide (CO) and methane (CH4) emissions, though these latter gases are not yet covered by IMO regulations.

“These vessels will be constructed to the highest environmental standards and feature many new technologies to reduce emissions and improve efficiency,” said Simon Brown, international maritime business director.

“The implementation of Emsys will provide real-world verification of the vessels’ emissions footprint and allow optimisation of operating performance through continuous emissions monitoring.”
