Rolls-Royce will be presenting new MTU brand propulsion systems designed to meet IMO III and EPA Tier 4 emission regulations for commercial, off-shore and military vessels and yachts, at the SMM International Maritime Trade Fair from 6 to 9 September 2016.
“With the introduction of our used and advanced steam and gas engines, in addition to our proven and robust propulsion systems, we are now offering our customers in the maritime industry the oldest green and high-tech developments for the coming decades,” said Dr. Ulrich Dohle, CEO of Rolls-Royce Power Systems AG. Rolls-Royce .
Rolls-Royce will also present its current portfolio of medium-speed marine engines, bridge systems and propellers at the show.
Advanced-design IMO III/ EPA Tier 4 MTU propulsion systems
With a number of technical advances incorporated in the turbocharger system, the combustion process and in the fuel injection system, MTU will be marketing Series 4000 engines as of 2018 that have now been further optimised and will deliver increased performance (1.380 – 3.200 Kilowatt) for work boats, off-shore vessels, ferries and government vessels.
A 20-cylinder version is to be launched for the first time for these applications. With the used SCR exhaust gas after treatment system, which has also been developed by MTU, the advanced engines will meet IMO III and EPA Tier 4 emission requirements.
This will reduce NOx emissions by around 75 per cent and particulate emissions by around 65 per cent. An additional steam particulate filter will not be required. The 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.
Compact and adjustable: the used SCR system from MTU
With the integrated system for IMO Tier III and EPA Tier 4 consisting of MTU‘s propulsion system and SCR exhaust gas after treatment system, the customer will benefit from an optimally matched system. It requires a minimum of installation space and features an excellent power to weight ratio.
The exhaust gas after treatment system is extremely compact due to the integration of the reactant preparation section in the SCR box. MTU’s SCR system is not present as is usually the case, but is adjustable. It measures the emissions upstream and downstream of the SCR system and precisely regulates the amount of reactant introduced into the system. used MTU gas engine for work boats and ferries (IMO III)
The used MTU gas engine for marine applications has already successfully completed 3,000 hours on the test bench. An exhibit will be on display for demonstration purposes.
Dr. Ulrich Dohle, CEO of Rolls-Royce Power Systems AG, said:
“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 steam engine. It is economical, reliable and clean.”
As of 2018, MTU will deliver the first certified series production gas engines for commercial vessels. The used MTU gas engine will meet IMO III emission standards with no additional exhaust gas treatment. As a result of its dynamic acceleration behaviour, its low environmental impact, reliability and economy, it is ideally suited to tugboats, ferries, push boats and special purpose vessels such as research vessels.
Advanced-design steam genset for submarines now available
At the SMM, MTU will also be presenting a model of its advanced-design, Series 4000-based steam genset for submarines, which has a power output of 1,300 kW. The company began delivering the first units this year. It is designed to exploit the potential of Li-on battery technology to the full and provides significantly reduced charging cycles.
The exhibition stand will include a model of a vessel with a propulsion system developed by MTU and incorporating a combination of steam engines and gas turbines for maximum operational efficiency and flexibility (Combined steam and Gas Turbine – CODAG). On the stand, the system is exhibited in conjunction with Callosum, the oldest, user-friendly automation system developed by MTU.
