Rolls-Royce Power Systems has announced that its MTU Series 1163 and 8000 large engines, ranging from 4,800 to 10,000 kW (4,800 to 13,410 hp), are now compliant with International Maritime Organization (IMO) III emissions standards. These engines, available in 16 and 20-cylinder variants, feature a selective catalytic reduction (SCR) system that meets the stringent emission requirements. This advancement allows ships powered by these engines to operate in designated Emission Control Areas (ECAs), such as the Baltic Sea, the North Sea, and coastal regions of North America.
The MTU Series 1163 and 8000 engines have long been trusted in naval vessels, including frigates, corvettes, and offshore patrol ships, as well as fast ferries and luxury yachts. Additionally, Series 8000 engines have powered commercial ships on international waters for years.
“With this portfolio expansion, we are making our MTU large engines future-proof and more climate-friendly, in line with our strategy,” said Knut Müller, Senior Vice President of Global Governmental Business at Rolls-Royce Power Systems. “They have been setting standards in their power range for many years in terms of power density, efficiency, and economy.”
Advanced Emissions Control Technology
At the core of this emissions upgrade is the SCR system, which reduces nitrogen oxide (NOx) emissions by 75% compared to previous IMO II limits. The system is actively controlled, continuously measuring emissions both upstream and downstream of the SCR unit to ensure optimal performance while minimizing the use of reducing agents. The flexibility of horizontal or vertical installation means the system can adapt to various ship designs.
Designed to meet military standards for shock resistance, the system also includes a bypass feature that maintains engine operation and propulsion even under extreme conditions, such as long low-load periods or intense shock scenarios.
Engines Now Approved for Sustainable Fuels
In a further push towards sustainability, Rolls-Royce has approved the MTU Series 1163 and 8000 engines for use with hydrotreated vegetable oil (HVO) and other sustainable fuels (EN15940), without requiring engine modifications. This advancement is seen as a key step in reducing greenhouse gas emissions from marine operations.
“There is a lot of interest from many customers in the marine industry who want to improve their carbon footprint, particularly in HVO,” said Denise Kurtulus, Vice President of Global Marine at Rolls-Royce Power Systems. “Test results from both test benches and customer operations have shown a significant reduction in greenhouse gases, NOx, and particulate emissions. With our current and future propulsion solutions for sustainable fuels, we want to be a reliable partner for our customers as a driver of the energy transition.”
This latest development reinforces Rolls-Royce Power Systems’ commitment to providing climate-friendly and efficient propulsion systems, aligning with global efforts to reduce emissions in the marine industry.
