Mitsubishi Heavy Industries of Nagasaki, Japan, has ordered
Emsys advanced
laser emissions monitoring equipment from WRSystems Ltd. for
two new-build vessels in construction for Carnival cruise line’s AIDA Cruise
brand.
The two 125,000-ton passenger vessels, which are the largest
ever constructed for AIDA Cruises, feature many innovations that will set
higher standards in vessel environmental performance, WRSystems says.
The Emsys continuous emissions monitoring system has a
unique laser-based emissions sensor, WRSystems says, allowing high accuracy
measurement for up to 10 exhaust stacks. The system also has the capability to
measure smoke (opacity) and particulate matter. The standard configuration
measures NOx, SOx and CO2, and has been awarded Type Approval by ABS to cover
each of these pollutants. Emsys can also be configured to report carbon
monoxide (CO) and methane (CH4). These latter gases are not yet covered under
IMO Regulations, WRSystems says, but are seen as critical going forward, as the
upward trend for using LNG as a marine fuel may bring further challenges
regarding air pollution.
WRSystems have previously announced key contract awards for
Emsys in the cruise sector for monitoring of exhaust gas cleaning systems
(scrubbers) on-board two of Royal Caribbean International Freedom class
vessels. The Emsys system has also achieved major success in the offshore
sector where multiple installations have been undertaken to meet local air
permit requirements, WRSystems says.
“WRSystems are delighted to have been awarded this highly prestigious
contract,” says WRSystems International Maritime Business Director Simon Brown,
in a company press release. “These vessels will be constructed to the highest
environmental standards and feature many new technologies to reduce emissions
and improve efficiency. The implementation of Emsys will provide real-world
verification of the vessels’ emissions footprint and allow optimization of
operating performance through continuous emissions monitoring. 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. WRSystems
is dedicated to setting new standards in performance and reliability in the
emissions monitoring sector, and this latest contract further underlines our
progress.”
‘These vessels will be the most environmentally advanced
cruise ships ever constructed, therefore choosing the correct suppliers is
critically important,” adds Irene Wong, purchasing coordinator of Mitsubishi Heavy Industries America. “We are pleased to
be working with WRSystems of Norfolk, Va., by installing their Emsys laser
emissions monitoring system on this project.”
