The International Maritime Organization’s (IMO) latest amendments to the NOx Technical Code introduce strengthened requirements for the testing, certification, documentation, and onboard verification of marine diesel engines. These updates reinforce global enforcement under MARPOL Annex VI and place additional responsibilities on shipowners and operators, particularly in relation to engine modifications, onboard parameter checks, and continuous compliance.
As emission regulations continue to evolve, Albion Marine Solutions remains committed to supporting shipowners, managers, and operators with comprehensive engineering and regulatory services to meet the enhanced NOx compliance requirements efficiently and with confidence.
Understanding the Latest NOx Technical Code Amendments
The revised NOx Technical Code places greater emphasis on consistency, transparency, and verifiable compliance across the global fleet. Key aspects of the amendments include:
- Stricter verification of Tier I, Tier II, and Tier III engine compliance
- Updated testing and measurement procedures for NOx emissions
- Enhanced documentation requirements for NOx-critical engine components
- Revised requirements for EIAPP certificates and Engine Technical Files
- Stronger expectations for onboard emissions verification and monitoring
- Expanded controls related to SCR, EGR, and other NOx-reducing technologies
- Clear re-certification triggers following major engine conversions or modifications
These measures are designed to ensure reliable NOx performance throughout an engine’s operational life and to improve uniformity in compliance enforcement across flag states and classification societies.
