Designed for marine engine applications up to 7,500 kW or 10,000 hp, Tenneco’s SCR aftertreatment system is designed to enable propulsion and auxiliary engines to cut NOx emissions and meet with IMO Tier III requirements, as well as US Environmental Protection Agency (EPA) Tier 4.
Recently Tenneco conducted saltwater sea trials on Texas A&M Maritime Academy ship General Rudder in the Gulf of Mexico, installed on a 33-year old 800 hp Tier 0 engine that was operational for the duration of the Academy’s summer cruise training period, enabling the vessel to meet with US EPA Tier 4 requirements in all conditions.
The AIP certificates cover key components of the system including the complete urea dosing and control system, injectors, load sensors and the human machine interface (HMI) remote monitor, as well as catalyst and reactor hardware configurations for IMO Tier III applications.
“Tenneco’s high horsepower SCR technology is designed to meet IMO Tier III NOx reduction requirements that take effect in 2016 and this classification further demonstrates our readiness to deliver these solutions for ships or vessels anywhere in the world,” said Jay Kedia, Tenneco md, large engine.
