The new NOx regulations are applicable for diesel engines installed on either:
- Imported vessels (acquired second-hand from international owners) or
- Chinese-flagged, international sailing vessels
which are only involved in Chinese domestic transport (either coastal or inland). They are required to comply with the IMO Tier II emission limits. This limitation applies to vessels imported after 1 September 2018 and to vessels converted to be engaged in domestic trade only after 1 September 2018. The NOx emission regulations cover vessels operating within the following waters:
- Chinese National 12 nm zone
- Hainan Island waters
- All navigable waters of Yangtze River
- All other inland navigable waterways of major cities
RecommendationsIf your vessel has a keel laying date before 1 January 2010, it might be a challenge to convert some diesel engines to the Tier II emission limits, and without a conversion, it may be more difficult to sell your vessel to Chinese owners for domestic trade. However, some engine manufacturers offer a solution to upgrade engine(s) to the Tier II emission limits.
