Gas Analysers and sensors – Operators/users
• The good news - Yes! they work, and they are quite robust when maintained
• Main reason for malfunction• Quality of installation• Quality of “instrument air”• Infrequent filter replacement• Service of air preparation units• Lack of cooling
• Total life cost of ownership varies a lot from make to make
• Frequent filter replacement• Cell maintenance /replacements• Calibration

LESSONS LEARNED: WHAT MARITIME CAN LEARN FROM LAND BASED CEMS EXPERIENCE ?
Norsk Analyse CEMS experience
• Land based – 250 + installations • Oil & Gas – 1.100 + installations• Marine – 1.600+ installations
Land based is the easy part
Inaccessibility = > remote support essential
Fast response from service/support department (First line response within 12 hrs)
Short mobilization of S/E globally
Annual service by skilled engineers reduce MTBF

Regulations and how to manage Compliance
MARPOL Annex VI
• Regulation for Air Pollution of Ships
NTC2008 NOx Technical Code
• General Regulation related to NOx
• Current situation:
The maritime air emission regulations are
focusing on what is coming out of the stack of
the ships
• Consequence:
Ship owners and operators need to be in
control of their emissions
• What to do…?
“Measure
emissions”

• Avoid build-up of ABS (Ammonium BiSulfate)
which eventually can foul the stack/boiler
Closed loop
• All of the above + …
• Optimize urea dosing
• Optimize NOx output
• Better transient load response

Scrubber Application – MES 1002 (Scrubber CEMS)
Scrubber installation with
MES 1002 Continuous Emission Monitoring
• Sensor measures SO2/CO2 ratio in accordance with
MEPC.259(68)
• Emission must stay below a certain threshold
• Sensor quality and performance is key, as the ship is not
allowed to operate the scrubber without correct readings
• Data must be recorded and stored for at least 18 months

On-board computer with interfaces Data CenterGeneral
• Data is collected on board from various sensors
• Satellite link for transfer of data
• Data is stored in a data center on shore
• Data can be accessed from “everywhere”
System features:
• Emission overview per ship or across your fleet
• User defined reports
• Pre-defined ECA zones
• Special overview panel for the crew on board
Interesting fact
• Despite having advocated for EmViz over the past
years market interest has just now picked up

Lessons learned from the Field
• Yards must observe correct installation – too many yards neglect
manufacturer's instruction.
• The stack is a very unfriendly place – nothing is maintenance free – too
many yards do not train in proper use and maintenance of the NOx sensor.
• When going to US waters the crew is particular aware of the NOx sensor
performance and maintenance condition (due to NOx ECA).
• SO2/CO2 sensor (scrubber) gets much more attention from the crew than
the NOx sensor (SCR).
• A “not to exceed limit” set by the MARPOL on NOx emissions is desirable
as this will ease in-field compliance measurements and interpretations.
