Emissions regulations are a critical component of the shipping industry’s efforts to reduce its environmental impact. IMO tier III and EU stage V are two important standards that are designed to address harmful emissions from vessels.
When it comes to emissions regulations, there are two key standards to consider: IMO tier III and EU stage V. The main difference between them is that IMO tier III applies to sea-going vessels, while EU stage V diesel emissions apply to inland waterway vessels.
In terms of installation, the requirements for reducing NOx emissions are simpler for IMO tier III vessels. A selective catalytic reduction (SCR) system is typically all that’s needed. However, EU stage V regulations for inland waterway vessels are more stringent. To meet the soot particle emission regulations, these vessels require both an SCR system and a diesel particulate filter (DPF).
So, while both standards aim to reduce harmful emissions, the specific requirements vary depending on the type of vessel and the type of environment it operates in.
