Why Emissions Compliance Matters for New Vessel Builds

As maritime environmental regulations tighten, vessels operating in Emission Control Areas (ECAs) and low emission zones must meet stringent IMO Tier III or Stage V Inland Waterways emissions standards. Single vessel approval (SVA) is critical for new builds to achieve compliance with MARPOL Annex VI and UK port authority regulations.

What is Single Vessel Approval (SVA)?

Single vessel approval enables custom or one-off vessels to be certified for emissions compliance without type approval. Following the Scheme B Approval process involves:

  • Engine and propulsion system assessments
  • Emissions testing and verification
  • Certification by a flag state or classification society
Scheme B Approval Guide

Key Compliance Requirements for ECAs and LEZs

  • IMO Tier III NOx standards (MARPOL Annex VI)
  • UK implementation of EU Sulphur Directive 2016/802
  • Local emissions control mandates (e.g., Stage V IWW)

Step-by-step guide to Scheme B Approval

  1. Adopt an early emissions strategy in the design process
  2. Upgrade your preferred engine with an exhaust aftertreatment compliant to IMO/EPA standards
  3. Engage with classification societies
  4. Conduct emissions modelling and PEMS testing
  5. Prepare a comprehensive compliance file

Designing for the future

Preparing for a low and zero emission future now will provide you with long-term benefits.

More stringent enforcement of emissions regulations is happening across the maritime industry. Therefore, achieving SVA ensures compliance, operational continuity and environmental credibility.
