addition to the increase in power, fuel economy is also enhanced, especially when operating in liquid fuel mode. This, together with the high loading capability and the proven reliability of the Wärtsilä 34DF engine, is seen as giving the new version a strong competitive advantage. By improving both the power and fuel ef? ciency, we aim to maintain the leading position that we have in gas engine technology and as a gas engine manufacturer. It is also important to point out that the environmental perfor- mance of the Wärtsilä 34DF is already excellent, and by lowering the fuel consumption we are also lowering the ex- haust emissions even further,? said Giulio Tirelli, Director, Wärtsilä Ship Power, 4-stroke Portfolio & Applications. The engine is able to operate ef? ciently and economi- cally on low sulphur fuels (<0.1% S), making it suitable for operation in emission-controlled areas. The newly ob- tained certi? cation of emission standard compliance from the United States Environmental Protection Agency (EPA) (17 January 2013) for the Wärtsilä 34DF further under- scores the environmental compliance of this engine. EPA certi? cation applies to United States ? agged vessels. The Wärtsilä 34DF is the ? rst dual-fuel engine ful- ? lling the EPA requirements and this is a very important statutory recognition of Wärtsilä dual-fuel technology,? says Andrea Bochicchio, Director, Product Management & Engineering, Product Centre 4-stroke, Wärtsilä Pow- erTech. With the passing of this compliance milestone, Wärtsilä anticipates that market demand in the USA for its range of dual-fuel engines will further increase. The ? rst engines will equip the Harvey Energy , an offshore supply vessel built for Harvey Gulf International Marine. Four sister vessels will shortly be supplied with the same Wärtsilä engines, thus further demonstrating both the vi- ability of lique? ed natural gas (LNG) as a marine fuel and its growing popularity among ship owners and operators. LNG fuelled vessels offer compelling operational cost sav- ings and signi? cant environmental bene? ts.TWO FOR THE MONEY : VOLVO PENTA S D13 & IPS900Volvo Penta D13 has now further been developed to meet EPA Tier 3 ? the new marine environmental emis- sion standard. The new version of D13 offers improved environmental properties with basically unchanged low- fuel consumption. The D13 is a diesel engine that has been developed within the Volvo Group. It is currently in operation in more than 450,000 heavy-duty applications, including buses, trucks and construction equipment. At Volvo Penta, this engine is further developed for use in in- dustrial applications for both off-road and electricity pro- duction and in unique custom marine applications. The full range of Volvo Penta D13 marine engines is now upgraded to meet the requirements of EPA Tier 3, which will take effect from 1 Jan. 2014. EPA Tier 3 in- volves a 40 percent reduction in particulate matter in the exhaust gases and a 20 percent reduction in NOx and hy- drocarbon. These high standards are met by the new D13 with the same power and basically identical fuel consump- tion. It is world-class fuel ef? ciency together with less en- vironmental impact. The upgrading of the environmental characteristics will neither change the performance, nor the fuel ef? ciency. Nor does it imply any changes in terms of design, size or installation ? in these respects there will be no difference to the boat builder, owner or operator. Volvo Penta D13 is available both as a propulsion engine (D13 MH) or as a marine genset (D13 MG) equipped with different cooling systems as an option.Separately, Volvo Penta is also launching IPS900 with Rating 3 for commercial boats, allowing more commercial boats to take advantage of IPS bene? ts ? improved fuel economy, better maneuverability and lower overall operat- ing costs. The IPS900 ? with a unique IPS, Inboard Per- formance System ? is now available for boats in the Coast Guard & Patrol, Supply Vessels, and Offshore Energy and Passenger Transport segments. This means great handling and operational bene? ts for boats used by, for example, police, customs, coast guard, rescue boats, pilots and sea ambulance, but also smaller passenger vessels and yachts. According to Volvo Penta, the new launch also means easier maintenance, longer lifecycle and higher increased uptime. Combined with superior fuel consumption, this provides a lower total cost of ownership; including extend- ed oil change intervals; longer intervals for propeller seal replacement and increased reliability. The IPS900 package uses the Volvo Penta D13 diesel engine with a power output of 700 hp. It is an ideal solu- tion for boats with Rating 3 (medium-duty use, approx. 2,000 service hours/year). The low-power usage means re- 22 MNJuly 2013MN July2013 Layout 18-31.indd 226/27/2013 1:00:04 PM
