JULY 19, 2016 — Rolls-Royce will be presenting new MTU brand propulsion systems designed to meet IMO III and EPA Tier 4 emission regulations for commercial, offshore and military vessels and yachts at this year's SMM event, to be held in Hamburg, Germany, September 6-9.
"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," says Dr. Ulrich Dohle, CEO of Rolls-Royce Power Systems AG.
Rolls-Royce will also present its current portfolio of medium-speed marine engines, bridge systems and propellers at the show.
IMO III/ EPA Tier 4 MTU propulsion systems
With a number of technical advances in the turbocharger system, the combustion process and the fuel injection system, MTU will be marketing Series 4000 engines in 2018 that have been further optimized and will deliver increased performance (1,380 – 3,200 kW) 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. MTU has developed a new SCR exhaust gas aftertreatment system that will enable the advanced engines to meet IMO III and EPA Tier 4 emission requirements, reducing NOx emissions by around 75 percent and particulate emissions by around 65 percent; an additional diesel particulate filter will not be required.
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 new SCR system from MTU
The integrated system for IMO Tier III and EPA Tier 4 consisting of MTU's propulsion system and SCR aftertreatment system, customers is optimally matched. It requires a minimum of installation space and features an excellent power to weight ratio.
The exhaust gas aftertreatment system is extremely compact thanks to the integration of the reactant preparation section in the SCR box.
MTU's SCR system is not preset 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.
New MTU gas engine for work boats and ferries (IMO III)
The new MTU gas engine for marine applications has already successfully completed 3,000 hours on the test bench.
"We can now confirm that the engine meets both our requirements and those of our customers: its performance and its acceleration behavior are similar to the excellent characteristics of a diesel engine," says Dr. Dohle. "It is economical, reliable and clean."
Asof 2018, MTU will deliver the first certified series production gas engines for commercial vessels. The new MTU gas engine will meet IMO III emission standards with no additional exhaust gas treatment. As a result of its dynamic acceleration behavior, its low environmental impact, reliability and economy, it is well suited to tugboats, ferries, push boats and special purpose vessels such as research vessels.
Advanced-design diesel genset for submarines
At SMM, MTU will also present a model of its advanced-design, Series 4000-based diesel genset for submarines, with a power output of 1,300 kW.
The company began delivering the first units this year.
Designed to exploit the potential of Li-on battery technology to the full, it provides significantly reduced charging cycles.
As a result of the new genset's lower fuel consumption, the operational range of vessels with the same size fuel tank has also been increased.
Combined diesel and gas propulsion systems and automation systems
As a systems provider, MTU is also able to develop and supply propulsion solutions that include ship automation systems.
Its SMM display will include a model of a vessel with a propulsion system developed by MTU and incorporating a combination of diesel engines and gas turbines for maximum operational efficiency and flexibility (Combined Diesel and Gas Turbine – CODAG).
It will be displayed in conjunction with Callosum, the latest, user-friendly automation system developed by MTU. Callosum allows monitoring and optimized control of the vessel's propulsion system as well as all on-board ship systems and has proved its effectiveness in operational assignments with numerous navies and coast guards.
Diesel genset for on-board power supply
A genset model based on the Series 4000 is offered by MTU as a diesel-electric propulsion unit or on-board power generator specifically for commercial applications such as supply vessels for offshore oil and gas platforms.
Gensets in this product family comprise a working vessel engine of the proven Series 4000 "Ironmen" design with either 8, 12 or 16 cylinders, a generator and the electronic control system all mounted on a common base frame and offering electrical outputs ranging from 720 to 2,140 kWe.
MTU Service to present reman engines and remote services
Rolls-Royce also offers MTU customers a comprehensive range of services for the entire service life of the propulsion systems. MTU's ValueCare portfolio, in addition to customer specific maintenance contracts, also includes fast response replacement parts supply, plus consumables such as coolants, engine oil and filters, in addition to remanufactured engines and parts. MTU additionally provides remote services to support the effective operation of the vessels and optimized maintenance services by making operational data and its evaluation available on a web-based portal.
