“We are ready for IMO Tier III”, said Dr Stephan Timmermann, MAN Diesel & Turbo Executive Board Member responsible for Marine Systems and After Sales. “We have the technologies in place to support our customers for this new era of environmentally efficient shipping."
The company’s Chief Technology Officer, Dr. Hans-O. Jeske, underpinned its technological readiness: “Exhaust Gas Recirculation and Selective Catalytic Reduction are technologies we not only have available but have operational experience with.”
MAN explain that Danish vessel Petunia Seaways is equipped with an MAN SCR system that has reliably operated for 9,000 hours to date and follows the world’s first Tier-III-compliant, two-stroke engine that was built by Hitachi Zosen Corporation in Japan for a general cargo carrier in 2011.
Similarly, the company received its first commercial order for an EGR system, to be applied aboard a 4,500-teu Maersk Line container newbuilding, in 2012. The system will be fully integrated with the vessel’s main two-stroke engine, to be built by Hyundai Heavy Industries’ engine & machinery division.
The marine engine builders say they have also met the Tier III challenge by introducing dual-fuel engines that can operate on clean-burning gas. The two-stroke, high-pressure ME-GI and four-stroke, 51/60DF engines were introduced with success in 2013 and 2012 respectively and give shipowners and operators the option of using either HFO or gas, depending on emission and price parameters.
Experts across all disciplines at MAN reckon that emissions regulation will remain a key driver for maritime technology development. “For MAN Diesel & Turbo, it is important to offer a variety of solutions so that customers can best balance their needs in terms of cost efficiency, environmental efficiency and operational profile”, Jeske explained. “For decades to come, we will see a rivalry of fuels. Versatility will be key. This is why we offer highly efficient, dual-fuel, two- and four-stroke engines, emission-control equipment and highly developed propeller designs.”
