Services

Field asset emission measurement services
built for GCC industrial reality.

Two service tiers — both grounded in the same rigorous field methodology and MCERTS-certified instrumentation. Tier 1 delivers a full exhaust chemistry audit. Tier 2 adds the mass flow measurement and unit conversion needed for GHG Protocol Tier 3 reporting and EPA Tier classification.

TIER 1

Combustion Health & Emissions Concentration Audit

On-site measurement of exhaust gas concentrations for each combustion asset, using the Testo 350 MCERTS-certified portable analyser. Results benchmarked against World Bank EHS Guidelines and Oman Ministerial Decision 18/2009 emission limits.

Tier 1 is the entry point for any operator who needs to know what their assets are actually emitting — without the complexity of mass flow measurement. It delivers a complete exhaust chemistry profile for each unit, a signed Asset Health Passport, and a clear pass/flag/elevated status against international benchmarks.

TIER 2

GHG Mass Emissions Inventory & EPA Tier Classification

Everything in Tier 1, plus exhaust mass flow measurement and fuel consumption cross-check — converting concentration readings (ppm) to mass emissions (g/kWh), the unit required for ISO 8178-4 test cycle compliance, EPA CFR Part 1039 Tier classification, and GHG Protocol Tier 3 Scope 1 reporting.

Tier 2 is the right choice for operators who need to report Scope 1 emissions to ESG auditors, project owners, or financing institutions — and for assets where EPA Tier compliance status needs to be formally established rather than estimated from manufacture year alone.

The process

From site visit to permanent record — four steps.

A structured, repeatable process that delivers a defensible emissions record on every engagement.

Asset scoping

Asset register review, ISO 8178 test cycle assignment (C1, D2, E3), and measurement scope definition for each asset class.

Field measurement

MCERTS-certified Testo 350 deployed on-site. Pre-test ASTM D6522 calibration check. Steady-state measurements. Full ambient and engine load documentation.

Passport issued

Signed report and updated Asset Health Passport per asset. Readings benchmarked vs. WB EHS Guidelines, Oman MD 18/2009, and EPA Tier limits.

Programme continues

Scheduled return visits build trend lines. Scope 1 data kept current. Client portal updated after every visit.

Add-on programmes

Ongoing monitoring and specialist services.

Both service tiers can be combined with ongoing monitoring programmes and specialist maritime compliance measurement.

Annual Monitoring Programme

Biannual site visits — summer and winter baseline — with full programme management, updated asset passports, cross-asset benchmarking, trend analysis, and a sustainability-ready data package for annual ESG and Scope 1 reporting cycles.

Maritime Vessel Compliance

Exhaust emissions measurement for marine vessels using the Testo 350 Maritime variant. Aligned to MARPOL Annex VI NOx and SOx technical limits, ISO 8178-E3 marine engine test cycle, and IMO DCS/CII data collection and reporting requirements.
