Emissions Monitoring for the Marine and Offshore Sectors

MARINE SECTOR – COMPLIANCE 1  LNGs and FPSOs  Scrubber installations  Engine optimisation and non-original parts replacement  Tier III compliance

ENERGY SECTOR – COMPLIANCE 2 Air Permits

EMSYS – SECOND GENERATION TECHNOLOGY 3  Combined emissions and PM measurement  Single penetration per stack  Patented ‘outside the stack’ PM measurement  Funnel space mounting  Approved for engines and boilers  Solid state sensors – no moving parts  Virtually maintenance free PATENTED ‘PARTICULATE MATTER’ SENSOR

4 EMSYS – SOLID STATE LASER EMISSIONS SENSOR  Calibration free design (only MARPOL verification checks necessary)  Four standard gases + water fraction  NO – NO 2 – CO 2 – SO 2 – H 2 0  Optional CO, CH 4 and NH 3  Laser sensor has no internal moving parts  Virtually maintenance free CALIBRATION FREE !

5 EMSYS – EXTRACTIVE HOT AND WET SAMPLING Emsys Rack PM Chamber 4. Hot gas returned to nearest stack 1. Hot gas extracted from stack 2. PM measured in patented PM chamber 3. QCL laser measures emissions concentrations

6 EMSYS – INSTALLED IN THE FUNNEL SPACE  Single penetration for PM and emissions, filter free stack probe  Short sample line, high flow rate  Large bore and inert sample lines  Low power consumption  Automated remote calibration  Funnel space mounting – no air conditioning required Emsys Rack Ethernet Out 10 stacks monitored by one Emsys system

7 EMSYS – SIMPLE INSTALLATION 3 DAYS RETROFIT

8 EMSYS – MULTIPLE SENSORS INTO A SINGLE SERVER

EMSYS – SIMPLE INTERCONNECTION VIA ETHERNET 9

EMSYS – PROVEN SCRUBBER MONITORING TECHNOLOGY 10

EMSYS – BUILT FOR THE TOUGHEST ENVIRONMENTS 11 Patented PM chamber High reliability ball valvesLaser emissions sensor High reliability vacuum pump Robust single unit enclosure

EMSYS – INTEGRATES INTO EXISTING SYSTEMS 12  Integrates directly into vessel’s automation and alarm system  Suitable for all engine types and test cycles  Configurable emissions reports  SQL-based software allows historical trending  Selectable fuel type (HFO – MDO – LNG ETC.)

13 EMSYS – COMPREHENSIVE ACCREDITATION  MARPOL Reg. 13 (NO X )  IMO MEPC. 184 (59), EGCS (Scrubbers)  IMO MEPC/CIRC.471 CO 2 INDEX mass emissions (NO X, SO X, CO 2 ) measurement of PM  MED wheelmarked  EPA permit approval (Region 4 G.O.M)

EMSYS – THE LOWEST COST INSTALLATION 15  Three day installation ‘in-service’  Low cost installation with minimal interconnects  Server can be positioned in ECR/bridge  Integral GPS or integration into vessel system  One day commissioning

EMSYS – THE LOWEST MAINTENANCE EMS AVAILABLE 16  No consumable parts – two washable filters  System operation from remote location (ECR)  Calibration free – only MARPOL verification check required  Annual maintenance costs of $2K – 6× less than competitor  Minimal spares holding required

EMSYS – SECOND GENERATION DESIGN TECHNOLOGY 17  Hot wet operation means no toxic condensate produced  Extractive design is significantly simpler to maintain than in-stack systems (only one laser sensor and one PM sensor)  Patented PM chamber eliminates PM sensors in each stack (along with labour-intensive cleaning regimes) and purges air system on each sensor  Unique design eliminates the requirement for continuous instrument grade air associated with dilution systems  Solid state laser is drift free – no continual use of calibration gas to correct calibration curve
