Mitsubishi Heavy Industries (MHI) of Nagasaki, Japan has ordered Emsys advanced laser emissions monitoring equipment from WR Systems, Ltd. (WRSystems) for two newbuild vessels under 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.
The Emsys continuous emissions monitoring system has a unique laser-based emissions sensor, allowing high accuracy measurement for 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 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 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.
