CEMS engineering and MARPOL Annex VI compliance for maritime operations.
MARPOL Annex VI sets global limits on SOx and NOx emissions from ships. Compliance requires accurate, documented measurement — whether through fuel oil sulphur content records, exhaust gas cleaning system monitoring, or direct stack CEMS. For LNG dual-fuel vessels, bunkering measurement adds a custody transfer dimension. FUTUREGAZ provides CEMS engineering, emissions data review, and LNG bunkering measurement support for vessel operators and terminal managers.
The maritime emissions compliance challenge
MARPOL Annex VI Regulation 14 limits sulphur oxide (SOx) emissions globally to 0.5% sulphur equivalent and to 0.1% in Emission Control Areas (ECAs). Regulation 13 limits nitrogen oxide (NOx) emissions for new marine diesel engines, with the NOx Technical Code defining certification and monitoring requirements.
Ship operators demonstrate compliance through one of three methods: using compliant low-sulphur fuel oil; using an approved exhaust gas cleaning system (scrubber); or using an alternative fuel such as LNG, methanol, or hydrogen. Each compliance method generates a documentation and data trail that is subject to port state control inspection. Gaps in that trail — missing calibration records, unresolved monitoring exceedances, incomplete data periods — create regulatory risk.
FUTUREGAZ services for maritime operations
CEMS and scrubber monitoring review
Review of exhaust gas cleaning system (scrubber) monitoring data and CEMS installations on board vessels. Assessment of SOx and NOx monitoring performance, data completeness, calibration records, and compliance documentation against MARPOL Annex VI requirements.
LNG bunkering measurement
Measurement review for LNG bunkering operations: ship-to-ship or shore-to-ship LNG transfer quantity determination, GIIGNL method application, custody transfer documentation, and delivered quantity verification for commercial settlement and IMO DCS fuel consumption reporting.
Emissions data verification and record review
Review of emissions monitoring records, fuel consumption data, and voyage reporting documentation for completeness and consistency. Support for IMO Data Collection System (DCS) and EU MRV reporting obligations, and pre-inspection record review.
Applicable regulations for maritime emissions
Air pollution from ships
IMO international convention setting limits on SOx, NOx, and particulate emissions from ships. Regulation 14 (SOx) and Regulation 13 (NOx) define the primary compliance obligations for vessel operators.
NOx certification and monitoring
IMO NOx Technical Code defining the certification requirements for marine diesel engines and the on-board NOx monitoring approach for vessels subject to MARPOL Annex VI Regulation 13.
Monitoring, reporting and verification
EU Regulation 2015/757 requiring monitoring, reporting, and verification of CO₂ emissions for ships calling at EU ports above 5,000 gross tonnage. Annual monitoring plan submission and third-party verification required.
Data Collection System
IMO mandatory data collection system for fuel consumption data for ships above 5,000 gross tonnage, operational from 2019. Annual fuel consumption, distance, hours underway, and transport work data reported to flag state.
