(NEW ORLEANS) — Caterpillar Marine Power Systems is pleased to announce the EPA Tier 2 Certification of all MaK™ engine platforms with cylinder volumes of above thirty liters. Included in the certification are the M 32 C, M 43 C, M 46 DF as well as the recently announced M 34 DF engine platform. The certification of the broad range of MaK power solutions provides customers operating in the American market, specifically in the commercial and offshore marine markets, a wide spectrum of power nodes to meet emissions regulations on U.S. flagged vessels.
“At Caterpillar, we recognize the needs of our customers to have flexible power solutions for any market, regardless of emissions regulations. We understand the market they are operating in is evolving in terms of environmental and performance requirements and strive to offer timely, innovative products that continue the Caterpillar legacy of proven performance,” Carsten Seeburg, Caterpillar Marine product definition manager said. “Building on that legacy is the recently introduced M 34 DF engine, which was designed and engineered based on high demand from our offshore customers.”
The M 34 DF dual fuel engine 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) operation as of 2015. Driven by upcoming fuel sulfur and NOx regulations in ECA, the M 34 DF will provide full flexibility for vessels operating in regulated and/or lesser regulated areas without major changes to the engine room or exhaust gas system, supporting the ease and simplicity of engine installation and certification. Although designed for unlimited operation on LNG, marine diesel oil and heavy fuel oil, the M 34 DF will reach industry-leading efficiency in gas mode, while operating as EPA Tier 3 certified.
“The M 34 DF engine will provide customers familiar with the legendary M 32 C platform a sense of ease in operation as the two platforms feature not only the same footprint but a large amount of shared components,” Seeburg continued. “The proven performance record of the M 32 C is well regarded throughout the industry with nearly 1,500 engines in the field populations. Vessel operators in the offshore segment, including platform supply vessels, anchor handling tug supply vessels and platform supply vessels, can confidently invest in the new M 34 dual fuel solution based on the success of the M 32 C.”
