MANThe International Maritime Organization’s decision to move forward with Tier III rules have been welcomed by German-based diesel engine and turbomachinery provider MAN Diesel & Turbo.

“We are ready for IMO Tier III,” said Dr Stephan Timmermann, 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. I am pleased that the adoption of the IMO regulations will save us from mushrooming national regulations. Now we have a clear set of rules.”

The company’s Chief Technology Officer, Dr Hans-O Jeske, also commented on MAN’s technological readiness for the new emission standards, which will affect newbuildings from 2016 onwards, saying: “Exhaust Gas Recirculation and Selective Catalytic Reduction are technologies we not only have available but have operational experience with.”

He said Danish vessel Petunia Seaways is equipped with a MAN SCR system that has reliably operated for over 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 4,500teu 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 and machinery division.

MAN Diesel & Turbo has also met the Tier III challenge by introducing dual-fuel engines that can operate on clean-burning gas and experts at MAN believe emissions regulation will remain a key driver for maritime technology development.

Dr Jeske said: “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. For decades to come, we will see a rivalry of fuels. Versatility will be key.”

Ole Grøne, Senior Vice President, Marketing & Sales for MAN’s Low-Speed business unit, said: “While fuel prices remain high and emissions become ever more stringent, ship owners look for the most efficient solutions for newbuildings and existing ships.”

While IMO Tier III will come into force for newbuildings from 2016 onwards, already today retrofits can significantly enhance fuel efficiency for existing fleets, he said.

“Any percentage point of fuel saving means lower operational costs and lower emissions – it’s a win-win situation.”
