IMO3 – John Deere

John Deere marine engines IMO Tier III compliant

Any John Deere marine engine can be easily retrofitted with a modular SCR unit to comply with the legislation and further reduce NOx levels. NPS Driven can provide these modules and also offer assistance with application and, if necessary, additional certification. In most cases, no additional certification is needed. The John Deere Marine Engines below can all be fitted with the Xeamos SCR unit by NPS Driven.

Xeamos – SCR unit

Xeamos after treatment by NPS Driven

Since January 1st, 2016, vessels over 24 meters in length must comply with IMO Tier III emission rules in the NECA areas. The MARPOL Annex VI regulation 13 (2008) sets the NOx emission requirements. US coastal waters, the Baltic Sea and North Sea are designated as Nitrogen Emission Control Areas (NECAs). Engines above 130 kW are restricted to approximately 2 g/kWh NOx, achieving a 75% reduction compared to IMO Tier II. Diesel engines require a Selective Catalytic Reduction (SCR) method to reduce the concentration of polluting nitrogen oxide (NOx) in the exhaust gases below the emission regulations set by IMO Tier 3.

With Xeamos after treatment  NPS offers heavy duty solutions for the current EPA Tier III John Deere engine lineup for both the propulsion ratings as for the 50Hz and 60Hz genset ratings
