Rolls-Royce will present its new MTU brand propulsion systems at the SMM in Hamburg this year.

The systems are designed to meet IMO III and EPA Tier 4 emission regulations for commercial, offshore and military vessels and yachts.

Dr Ulrich Dohle, CEO of Rolls-Royce Power Systems AG, said: “With the introduction of our new and advanced diesel and gas engines, in addition to our proven and robust propulsion systems, we are now offering our customers in the maritime industry the latest green and high-tech developments for the coming decades.”

The MTU brand will be marketing Series 4000 engines with the new SCR exhaust gas aftertreatment system, which has also been developed by MTU. The engines will reduce NOx emissions by around 75% and particulate emissions by around 65%.

Series 4000 engines for yachts will be slightly modified and marketed with MTU’s SCR system, which will meet IMO III regulations as of 2017.

The exhaust gas aftertreatment system is extremely compact due to the integration of the reactant preparation section in the SCR box. MTU’s SCR system is adjustable and measures the emissions upstream and downstream of the SCR system.

As of 2018, MTU will deliver the first certified series production gas engines for commercial vessels.

Dr Dohle added: “We can now confirm that the engine meets both our requirements and those of our customers: its performance and its acceleration behaviour are similar to the excellent characteristics of a diesel engine. It is economical, reliable and clean.”

At the SMM, MTU will also be presenting a model of its Series 4000-based diesel genset for submarines. It has a power output of 1,300 kW and is designed to exploit the potential of Li-on battery technology.

The new genset’s lower fuel consumption, the operational range of the vessels with the same size fuel tank has also been increased.

Its stand at the show will also include a model of a vessel with a propulsion system developed by MTU and incorporating a combination of diesel engines and gas turbines (Combined Diesel and Gas Turbine – CODAG).

The system will be exhibited in conjunction with Callosum, a user-friendly automation system developed by MTU.

Rolls-Royce provides MTU product customers with a comprehensive range of services for the entire service life of the propulsion systems. MTU‘s ValueCare portfolio includes fast response replacement parts supply, plus consumables such as coolants, engine oil and filters, in addition to engines and parts.

Rolls-Royce will also be presenting its current portfolio of medium-speed marine engines, bridge systems and propellers on the stand.

Visit them in Hamburg from 6 to 9 September 2016 on Stand 305, in Hall 3A.
