NEW ORLEANS, USA – Rolls-Royce will be presenting its latest MTU-branded propulsion systems for commercial vessels and offshore shipping at the International Workboat Show being held at the Morial Convention Center in New Orleans, USA between November 30 and December 2. The MTU brand is part of Rolls-Royce Power Systems.
To mark the 20th anniversary of the Series 4000, the joint MTU and Rolls-Royce exhibition stand (no. 2601) will be showcasing its gradual transformation from the earliest incarnations to a modern, green, high-tech propulsion system. This will include initial versions of the Series 4000, the “Ironmen” engine, the new improved M05 diesel unit and MTU’s new gas engine.
New M05 Series 4000 diesel
Centre-stage on the MTU stand will be improved diesels meeting IMO III and EPA Tier 4 requirements. These have already racked up more than 4,000 hours of runtime on MTU’s test stands in Friedrichshafen, Germany, and in Aiken, South Carolina. MTU will be supplying them from 2018 as primary propulsion systems for tugboats, ferries and supply vessels, and also as gensets for supplying electrical power to ships and platform installations. Improvements to the engines’ turbocharging, combustion process and injection systems used in combination with the new MTU SCR unit, reduce nitric oxide emissions by 75% compared to IMO II, and particle emissions by 65% compared to EPA 3. A separate diesel particulate filter is not required.
New MTU gas engine for working boats
MTU’s new 16-cylinder gas engine is based on the tried-and-tested MTU 16V 4000 M63 workboat diesel and will be marketed with a power range of 1,500 to 2,000 kW from 2018. An 8-cylinder version is to follow, with a power range of 750 to 1,000 kW. The new gas engine is especially well-suited to tugboats, ferries, push boats and special purpose vessels such as research craft. MTU gas engines come with multi-point gas injection, variable combustion pressure control and improved turbocharging. The combustion design concept ensures efficient use of fuel and enables IMO III emission standards to be met without additional exhaust aftertreatment. A compact, built-on oxidising catalytic converter (oxi-cat) is used to achieve EPA Tier 4 standards. The jacketed design allows the engine room to be fitted out in the same way as for a diesel engine.
Real-life piloting manoeuvres have already been simulated on the test stands, showing the engine to have the fast acceleration characteristics of a diesel. The 3,600 hours of operation already racked up on the test stands have shown that the gas engine is up there with the Series 4000 diesel in terms of reliability.
MTU Ironmen engines
Also on show on the stand will be a cutaway model of the MTU Ironmen 8V 4000 workboat engine – ideal for powering harbour tugboats, fire-fighting vessels, ferries and river barges. Certified to US EPA Tier 3 emissions requirements without exhaust aftertreatment, the Series 4000 Ironmen engines are available in 8, 12 and 16-cylinder configurations. They are to power diesel-mechanical and diesel-electric propulsion systems, onboard power generators and MTU hybrid drive systems. Used as part of diesel-mechanical applications, Ironmen engines meet power demands of 560 to 2,000 kW, with diesel-electric propulsion systems and onboard power generators producing between 650 and 2,000 kW.
Full-lifetime service solutions
As a system provider to the marine industry, MTU also offers comprehensive services during the entire lifetime of its propulsion solutions. The MTU ValueCare range includes customised maintenance solutions, rapid supply of spare parts and consumables such as engine coolant, engine oil and filters and also remanufactured engines and parts.
In 2018 Rolls-Royce will deliver the first certified MTU gas engines for commercial marine applications.Image Download (jpg, 803 KB)
MTU Series 4000 with SCR: Customers benefit from a perfectly integrated concept for IMO Tier III comprising an MTU drive and SCR system which is compact and which offers an excellent power-to-weight ratio. Two different SCR systems are being offered so that, depending on the installation space, the customer can choose between one cubic box or two flat boxes (picture).Image Download (jpg, 3 MB)
The MTU exhibit presented at SMM 2016 shows the development from the origins of the Series 4000 into a modern green and high-tech propulsion system in one engine. This includes the original Series 4000 diesel engine versions M00 to M01 (grey) as well as the engine version M03 commonly known as Ironmen (blue). The new version M05 is also illustrated (green), which will meet IMO III and EPA Tier 4 emission legislation and the new MTU gas engine (yellow).Image Download (jpg, 4 MB)
