About us
Marine Emissions Monitoring
The Emsys ‘Classic’ was originally introduced to the maritime industry at SMM 2010 . Following successful market acceptance, a 2nd generation marine emissions monitoring system, the ‘Emsys-iS’, was launched in January 2015.
The Emsys Classic was developed by WR Systems of Norfolk, Virginia. The second generation Emsys-iS was developed from a shipowner request for a smaller, more flexible Emsys which could provide reliable and accurate compliance monitoring of the scrubbers in their fleet. Extensive feedback from in-service operation and specific requirements from the shipowner ensured the evolution of our EMS technology into the Emsys-iS. Developed, prototyped and type tested in the UK, the Emsys-iS has been built in our modern UK manufacturing facility since its launch.
In September 2016, Emsys Maritime Ltd acquired the Emsys product Intellectual Property Rights (IP) from WR Systems Ltd.
Former Director of Commercial Maritime Programs at WR Systems, Simon Brown, joined the team as Managing Director. Mr Brown is a qualified Marine Engineer and held the position of Chairman of the IMO Working Group of experts which revised the NOx Technical Code as part of the MARPOL Annex VI revisions.

Vast experience in monitoring ship emissions and marine scrubbers
Emsys systems have been installed on 7 different types of marine scrubber and we currently monitor over 70 scrubbers for compliance applications.
Emsys EMS technology is suitable for deployment on all ships types. Emsys has been installed on board cruise ships, LNG carriers, container ships, drillships, semi-submersibles and tankships. Emsys can monitor all types of marine engine (2-stroke and 4-stroke diesels), marine boilers, waste incinerators and gas combustion units (GCUs).
Emsys emissions monitoring systems have been supplied to many of the worlds’ major shipbuilders including Fincantieri, Samsung Heavy Industries (SHI), Hyundai Heavy Industries (HHI), Mitsubishi Heavy Industries (MHI), STX Offshore & Shipbuilding and Daewoo Shipbuilding and Marine Engineering (DSME). Emsys Maritime’s project team are flexible and highly responsive to customer needs. We understand the challenges faced by shipbuilders in the current economic environment and our mission is to deliver a stress-free project, on-time and on-budget.
In 2012 Emsys was awarded a U.S Patent for measurement of Particulate Matter (PM) in marine applications. Although not regulated as an individual species, PM is becoming more of a global health concern and is being chosen as an additional monitoring parameter by many progressive shipowners. The Emsys-iS can additionally monitor opacity, ideal for measuring visible black smoke emissions for applications including Alaska Marine Visible Emissions Standards 18 AA 50.070.
In 2013, the team at Emsys were rewarded for their development efforts by winning the ‘Seatrade Award for Clean Shipping’. Known as the maritime ‘Oscars’, the awards are held annually and the nominations include a ‘who’s who’ of the worlds’ most prestigious shipowners and technology suppliers.
Emsys is trusted by the worlds biggest shipowners and shipbuilders. Contact our team to find out how we can help you with your marine emissions monitoring requirements.
Emsys-iS Marine Emissions Monitor
Emsys-iS
QCL Multi-Gas Laser Sensor | Small Footprint | Low Power requirements | Calibration-Free | Type Approved | Mass Emissions Reporting | Particulate Matter | Black Smoke Detection | MARPOL Annex VI NOx Technical Code | Direct Measurement and Monitoring
Key features:
- IP56 stainless steel grade 316L enclosure rating allows Emsys to be installed on the weather deck or in the upper funnel section/above the scrubber. This means we can install close to the measurement points keeping the sample line lengths to a minimum and response times rapid
- Extremely low power requirements >3kW typically. Only a single power supply is required to the Emsys enclosure. Stack probe and heated sample line power are distributed from the main enclosure to each stack measurement point contained within a single umbilical
- Emsys operates in temperatures up to 55 degrees C ambient which means our systems don’t need to be sited in a cooled space or require a self-contained air conditioning unit to keep them cool
- Emsys’s compact size (800mm x 600mm x 300mm) and low weight (>60kg) makes it extremely easy to install as a retrofit item, even in the tightest of spaces
- The drift free Quantum Cascade Laser (QCL) sensor only requires mandatory calibrations as per the monitoring manual or Flag/Class requirements. This means you require less of the expensive calibration gas (and the headaches of shipping it to your vessel) that marine EMS systems typically consume
- The Emsys-iS features SO2 and CO2 gases as a standard supply. Additional gases including NO, NO2, CH4, CO, O2, NH3 and PM are available by ‘plugging in’ new laser modules into the existing sensor, combined with a simple software upgrade
- Type Approved by ABS and accepted by all IAC’s Class Societies including DNV-GL and Lloyds Register for multiple scrubbing applications
- Unique Type Approved emissions mass measurement capability can be used for EU MRV reporting. Emsys is the only EMS technology to feature exhaust gas mass flow measurement by all 3 allowable methods in the NOx Technical Code (2008):
- → Carbon Balance method Air-Fuel method
- → Direct Measurement method using a Type Approved mass flow sensor
- Our QCL laser sensor is drift and cross interference free making it ideal for scrubber applications where cold and wet gases are required to be measured. Traditional IR and UV based systems can read incorrectly in these aggressive cold and high moisture applications. It is also up to 10x faster to respond to changes in concentration than traditional emissions monitoring analysers. This is a big benefit in multi-scrubber applications where the guidelines require monitoring each stack every 4.75 minutes
- The QCL sensor is highly accurate. The standard Emsys ‘scrubber’ system measures accurately to a lower detectable limit of 3 ppm SO2 making it suitable for MEPC.184 (59) applications. We also offer an extended range version which can measure down to a lower detectable limit of 1 ppm SO2 where required.
- Emsys is modular technology meaning the standard system can measure up to 4 stacks from a single enclosure, however we can use differing configurations to expand the system to measure up to 16 stacks
- Emsys is supplied with a comprehensive software reporting suite. EmChart meets all the mandatory maritime air emissions regulatory reporting requirements. It also features a user-friendly graphical user interface (GUI) to display, record, trend and print emissions data to meet your own specific requirements
- Emsys captures a wide variety of data in addition to gaseous emissions. We have standard MODBUS based interfaces which allow Emsys to integrate with the vessels automation and alarm system. The interface can also be configured to provide emissions feedback for scrubber and SCR control loops
Emsys-PM Smoke Density Monitor
Emsys-PM is a combined Opacity (smoke density) and Particulate Matter (PM) sensor. Using cross-stack LED optical technology, the sensors are ideal for monitoring smoke density and PM for maritime applications.
The sensors can be configured as a stand-alone devices which directly interface to the vessels automation system using MODBUS, or alternately as a discrete monitoring system with recording and reporting capability. Either configuration is capability of interfacing with our Emsys-iS emissions monitoring technology allowing a greater array of reporting formats.
The sensors are marine Type Approved by Lloyds Register and have been extensively tested for suitability in the marine environment. Emsys-PM’s robust construction and reliable operation have resulted in a reference list of over a thousand installations in the maritime sector.
Emsys-PM can be used to monitor smoke density or PM in all types of marine diesel engines (2-stroke & 4-stroke), marine boilers (main and auxiliary), incinerators and inert gas (IG) generators.
Using cross stack technology, Emsys-PM can be supplied for newbuilds or in kit form for retrofit to existing vessels. The kit includes all items such as the sensor heads, flanges, air purge blower, cabling and detailed installation instructions to allow the ships crew to install themselves.
The sensors are virtually maintenance free. Housed in robust stainless steel IP65 enclosures, they only require occasional cleaning of the lens reducing workload on the vessels crew.
