its product line-up is fresh and ahead ofthe curve. ?Where should I start? We have the dual fuel engine L35/44 on the test bedwhich is running, intended for use inmaritime and power plant applications. We have working on a two-stroke, we have a gas engine, meeting Tier III which is coming; we have a new high speed en- gine,? said Dr. Umlauft. ?On the engine side, we have a lot of development, from the high speed through the two stroke low speed, moving toward environmentally friendly initiatives but also working to- wards greater engine efficiencies.? In fact, from the fulfillment of tech- nologies to comply with evolving envi- ronmental rules, Dr. Umlauft is confident his company is up for the task. ?From the technical point of view, I am sure we are able to solve (the environmental) issues. The question is: are our customers ableto invest in the new technology based on the new legislation, particularly in light of the ongoing sluggish world econ- omy??MAN Diesel & Turbo introduced its L35/44DF engine, the latest addition toits four-stroke portfolio, at SMM 2012 in Hamburg. Spurred on by developments in environmental legislation and the strict emission limits resulting from that, theengine offers dual diesel fuel-gas running and can also be introduced as a retrofit to engines already in service. The first prototype entered its test phase at the beginning of 2012?s second quar- ter at MAN Diesel & Turbo?s Augsburg facility. A V-type engine version is being developed simultaneously that will en- large the power-output range of the com- pany?s dual-fuel engine portfolio as part of MAN Diesel & Turbo?s market strat- egy. The company is introducing the L35/44DF engine at a time where sepa-rate emissions legislation for harbors is set to come into play, in addition to the upcoming IMO Tier III emission regula- tions for marine applications. Accord- ingly, MAN Diesel & Turbo views the introduction of another engine that offers the option of operation on gaseous fuels as timely, also in the context of ship own- ers? increasing environmental awareness. With the L35/44DF engine, MAN Diesel & Turbo is continuing the expansion of its product program with a dual-fuel en-gine based on common rail technology. MAN Diesel & Turbo?s development objective with the new engine was to pro- duce a high efficiency/ high specific power output unit that complied with IMO Tier II emission limits in diesel mode and IMO Tier III limits in gas op- eration. A high degree of fuel flexibility (HFO, MDO, MGO and natural gas) was another primary objective. With an out- put of 530kW/cylinder, the inline 35/44DF is available in 6 ? 10 cylinder configurations, equivalent to total power outputs from 3.2 MW to 5.3 MW. This represents the highest power output avail- able in the segment and complements that offered by the larger L51/60DF type. The company also announced an addi- tion to its engine program: the D7 high-speed engine which delivers a 1.5 ? 5 MW output at 1,000 ? 2,000 rpm and isdesigned to serve a broad range of appli- cations. The company contends that the D7 closes the gap between its smallest medium-speed and largest high-speed en- gines and sets new standards in fuel effi- ciency, power/weight ratio and TBO-intervals. It has targeted tugboats, workboats, off- shore service and supply vessels, navy patrol boats, super yachts and fast ferries as its core applications. The new engine will additionally serve non-marine mar- kets such as the offshore, onshore power generation and rail segments. It will also be available as a gas-powered version for certain applications. The D7 will play a central role in a new propulsion train de- vised by MAN Diesel & Turbo. Cus- tomers will be offered the engine as part of a package that includes gearboxes, propellers, switchboards, auxiliarygensets, and energy storage solutions. Or- ders for the new engine can be placed starting in 2014.12Maritime Reporter & Engineering News INTERVIEWDR.
