Mitsubishi Heavy Industries (MHI) has placed an order with WR Systems for its Emsys advanced laser emissions monitoring equipment to be installed on two new cruise ships.
The two 125,000t cruise vessels are the largest ever built for Carnival cruise line's AIDA cruise brand..
WR Systems said that the Emsys monitoring system has a laser-based emissions sensor that enables high accuracy measurement of up to 10 exhaust stacks for NOx, SOx, and CO2.
Emsys can also be configured to measure smoke (opacity), particulate matter (PM), carbon monoxide (CO), and methane (CH4).
Currently, carbon monoxide and methane are not covered under IMO Regulations but could be critical in future, as the extensive use of LNG as a marine fuel may bring further challenges regarding air pollution.
WR Systems international maritime business director Simon Brown said that the vessels will be built to high environmental standards and feature new emission-reducing and efficiency-improving technologies.
"The implementation of Emsys will provide real-world verification of the vessels' emissions footprint and allow optimisation of operating performance through continuous emissions monitoring," Brown said.
"Emsys has now been implemented in many critical environmental monitoring applications; we believe our combination of high accuracy laser technology and low operating costs to be a significant contributor to the award of this contract."
Previously, WRSystems had won contracts for Emsys in the cruise sector for monitoring of exhaust gas cleaning systems (scrubbers) on two of Royal Caribbean International's 'Freedom' class vessels.
Emsys was developed to help vessel-owners comply with MARPOL Annex VI maritime emissions regulations.
The system can leverage data via GPS and electronic charting to help in-voyage compliance management in Emission Control Area (ECA) zones.
