Emsys Chosen for Scrubber Monitering

As 2015 approaches, the anticipated rush to install scrubbers has started and announcements of major scrubber contracts are commonplace. Emsys, the laser based emissions monitoring system from U.S. technology firm WR Systems, Ltd. (WR), have now been selected as the compliance monitor system on five differing scrubber types.

There are various scrubber designs currently being installed for owners keen to become both compliant and efficient. Depending on the vessel type and intended application, these include seawater, freshwater, hybrid, dry, open loop and closed loop amongst other novel designs.

WR designed their Emsys system using laser sensor technology; this means that the exhaust gas is measured in the same form as in the stack and not conditioned, cooled or dried. The laser allows the system to accurately measure the emissions at low gas temperatures with high humidity present in the exhaust stream. Significant benefits of the technology are based around the elimination of consumable spare parts and regular maintenance.

Although scrubbers only require monitoring of the SO2/CO2 ratio for compliance, the Emsys system has found favor with shipowners due to its capacity to measure multiple gases including NOx, SOx, CO2, CO, CH4 and PM. Applications using a combination of an SCR and scrubber, combined with possible operation of engines using LNG, require a wide range of data necessary to optimize performance and provide compliance. Simple scrubber monitors are not suited to provide this level of reporting.

“Scrubbers are complex systems and when combined with other emissions reduction devices/alternate fuels become an important part of the vessel’s efficiency and compliance calculations. The cost of operation for these systems can be optimized if you have accurate feedback from the top of the stack,” explained Simon Brown, WR’s Director of International Maritime Business. “Many of these systems are ‘tuned’ using pumps, fans or consumables such as caustic soda. These are quantifiable running expenses and need to be used sparingly to maximize the operational efficiency. Being able to accurately optimize the assets whilst having the knowledge that Emsys is providing a highly accurate, validated and Flag State Approved compliance record is one of the main factors for Emsys success with ship-owners.”

WR is bound by confidentiality on most of their scrubber projects, but they have disclosed that in addition to the installations of Emsys on Royal Caribbean International announced last year, the Emsys system is to be installed on multiple cruise ships and cargo vessels. Amongst an influx of recent contracts for Emsys including awards from Far East shipyards for both scrubber and traditional monitoring applications, these projects seem to underline the shipping industry’s confidence in emissions reduction technology.

WR claims an order book stretching into 2015 and an ever expanding customer base which has understood the benefits gained from installing their laser monitoring system. WR further explains that installing technology such as Scrubbers is not the total solution; the ability to optimize efficiency and maintain operational compliance is paramount in delivering a competitive advantage.
