Forget all the worries about how industry would be able to comply with the coming changes to the regulatory scheme that affects marine propulsion and related emissions. De- mand has met supply and it has done so robustly and in impressive form. And, if the past month is any indication, the innovation in the market is more than keeping up. This month, we provide just a sampling of the impressive devel- opments in marine propulsion. Clearly, workboat operators now have a cornu- copia of options for the repower and newbuild market, alike. CATERPILLAR : MAK DUAL FUEL ENGINEAt the end of May, Caterpillar Ma- rine Power Systems announced the development of a second High Perfor- mance MaK Dual Fuel Engine. Accord- ing to Caterpillar, the MaK M 34 DF, a new marine dual fuel engine platform for the commercial marine industry, boasts a power rating of 500 kW per cylinder at 720 and 750 rpm in diesel and gas modes, and will share the same footprint as the highly successful M 32 C engine series. The M 34 DF will be capable of running on natural gas as an alternative to marine diesel oil or large and complex scrubber installations for Emission Control Areas (ECA) opera- tion as of 2015. First engine deliveries are foreseen for October 2014. Were pleased to continue to de- liver on our commitment to bring innovative, ef? cient solutions to the commercial marine market,? said Carsten Seeburg, MaK product de? ni-tion manager. Our customers want a fuel-ef? cient, sustainable propulsion product with operational ? exibility for both IMO and EPA regulated waters and were aiming to exceed their ex- pectations with the M 34 DF engine.? Driven by upcoming fuel sulfur and NOx regulations in ECA, the M 34 DF will provide full ? exibility for vessels operating in regulated and/or lesser regulated areas without major changes to the engine room or ex- haust gas system, supporting the ease and simplicity of engine installation and certi? cation. Although designed for unlimited operation on LNG, ma-rine diesel oil and heavy fuel oil, the M 46 DF will reach industry- leading ef? ciency in gas mode. With a bore of 340 millimeters and stroke of 460, the engine was designed to be the preferred choice for gas electrical and mechanical propulsion applications notably in the offshore and cargo segments. The engine de- sign features new real-time combus- tion monitoring, Flexible Camshaft Technology functionality as well as a lower valve train and several innova- tive monitoring and component solu- tions to ensure maximum safety dur- ing operation. Caterpillar will offer its renowned service and support for the new MaK dual fuel engine, including installation and application, system in-tegration support, as well as customer and crew training. The M 34 DF will pass customer acceptance tests and classi? cation approvals in Rostock, Germany and will be sold through Caterpillars MaK dealer network. WÄRTSILÄ LAUNCHES NEW, POWERFUL 34DF ENGINEWärtsilä has further developed its dual fuel technology and has intro- duced a more powerful version of its Caterpillar, Wärtsilä and Volvo Penta introduce new, ef À cient and environmentally compliant engines. A crowded market becomes even more competitive. Edited by Joseph Keefe Good News Comes inThrees July 201320 MNMN July2013 Layout 18-31.indd 206/27/2013 12:59:48 PM
