MAN Energy Solutions’ after-sales division in Augsburg, Germany—MAN PrimeServ Augsburg—has developed a selective catalytic reduction (SCR) solution that will be retrofitted aboard the MS Amadea, a cruise ship chartered by PHOENIX Reisen GmbH Bonn (Germany) and managed by BSM Cruise Services. Also known as Das Traumschiff, the Amadea is well-known in Germany as the main filming set for a very popular television series.The retrofit calls for the integration of two of MAN’s SCR systems…

As one of the largest, most widely known naval architecture and marine engineering firms in the world—celebrating its 90th anniversary in 2020—Robert Allan Ltd. is no stranger to being approached by marine engine manufacturers seeking input on their products. But no one’s ever come to the Vancouver, Canada-based company as early in the process as Caterpillar did during the development of its U.S. Environmental Protection Agency (EPA) Tier 4 Final solutions.Like many in the industry, the team at Robert Allan Ltd.

Designed for heavy duty propulsion and genset applications, Volvo Penta has revealed a D8 engine and after treatment system that meets the International Maritime Organization (IMO) Tier III at the Nor-Shipping international exhibition and conference in Norway.Volvo Penta is launching a new D8 engine and after-treatment concept to comply with the International Maritime Organization (IMO) Tier III standards. The IMO Tier III regulation will stipulate a reduction in nitrogen oxides (NOx) emitted of around 75 per cent – depending on engine size – when compared to current IMO Tier II levels.

In October of 2014, news of Oceaneering’s purchase of GE Transportation’s newest marine engine offering was making waves. These engines – ones which meet EPA Tier 4i and IMO Tier III Emissions standards – without the need for a Selective Catalytic Reduction system (SCR) exhaust gas after-treatment, had workboat operators everywhere looking at new possibilities. Before that, Harvey Gulf International Marine also entered into a contract to construct a new Multipurpose Field Support Vessel (MPFSV) at Eastern Shipbuilding, this one also powered by GE’s Tier 4 compliant, EGR main engines. That’s important because Harvey Gulf, the recognized North American leader in rolling out LNG and dual fuel propulsion vessels, in this case, selected a pure diesel engine.

Volvo Penta’s new IMO Tier III concept was revealed for the marine sector at the Nor-Shipping international exhibition and conference in Norway, ahead of further regulations coming into force in Europe. Volvo Penta is launching a new engine and aftertreatment concept to comply with the forthcoming implementation of IMO Tier III standards, enabling a global solution for commercial marine operators. The solution is based on both the company’s own experience along with expertise from the Volvo Group in leading selective catalytic reduction (SCR) technology…

On the way to Tier IV compliance, it turns out that experience counts. In late February, the nation’s first Tier IV, Selective Catalytic Reduction (SCR) tugboat was christened. That’s probably not earthshaking news all by itself – after all, SCR isn’t all that new – but the event likely ushers in a new era of powerful domestic workboats that also come with a greener environmental footprint. How all of that comes together is a bigger story, and one which will play out again and again in the coming year or two. At the heart of it all is Crowley subsidiary Jensen Maritime Consultants, who today lead the design field with no less than seven Tier IV, SCR versions in development. Digging deeper, it isn’t hard to see why. The new Tier IV hull comes with a silver lining.

MAN Diesel & Turbo has signed a contract with Sembcorp Marine in Singapore to supply the dual-fuel propulsion system – including exhaust-gas after-treatment – for a New Semi-submersible Crane Vessel (NSCV) for Heerema Offshore Services. The scope of the contract – signed on 30 October, 2015 – provides for 12 × MAN 8L51/60DF four-stroke engines + 12 × MAN SCR (Selective Catalytic Reduction) systems. MAN Diesel & Turbo states that the total power output of the engines is some 96 MW and believes it – with the exception of power barges – to be one of the largest engine installations the world has ever seen aboard a single ship. Certainly, it is the first vessel of this size to feature dualfuel technology and, upon completion, will be the largest vessel of its kind globally.

Today’s workboat operators must navigate increasingly stringent IMO and EPA environmental and emissions regulations in and around ports and rivers. As the drama unfolds, selective catalytic reduction or SCR is emerging as a viable vehicle to do just that. At the same time, fears about space constraints for smaller vessels and the hassle of carrying and handing urea for these systems are rapidly evaporating, as well. Two different firms – both familiar names in propulsion markets – have embraced SCR as the way forward. Both, Tenneco and Volvo Penta, rely on deep roots in these markets and significant experience in the effort to reduce emissions from engines.

GE Marine’s (NYSE: GE) 12V250 marine diesel engine received U.S. EPA Tier 4 Certification. GE met the emissions requirements through non-Selective Catalytic Reduction (SCR) technology that requires no urea-based after-treatment. The company is also working towards U.S. EPA Tier 4 and IMO Tier III Certification for additional models and families of its marine engines utilizing the same non-SCR technology. “Achieving this certification validates our unique ability to meet Tier 4 emissions requirements without the disadvantages of after-treatment.

At the International Workboat Show, GE Marine will unveil its ecomagination-qualified 12-cylinder V250 Marine Diesel engine that reduces emissions by 50 percent to meet EPA Tier 4i and IMO Tier III emission compliance. GE’s breakthrough technology eliminates the need for a urea-based after-treatment emissions reduction system. In addition, the 12V250 engine offers increased power of 3,150 kW at 900 rpm and 3,500 kW at 1000 rpm while maintaining low life-cycle cost, reliability and fuel efficiency.

Tenneco and Cormetech sign agreement to design marine engine ultra-large diameter selective catalytic reduction (SCR) catalysts. The MARPOL Annex VI and EPA Tier IV regulations require an 80% reduction in NOx emissions, thus driving the need for engines to include aftertreatment strategies such as SCR. Tenneco’s SCR solution, incorporating the Cormetech catalyst, will be designed to help the marine industry comply with the new emission regulations. “Tenneco is an established leader in designing and developing diesel aftertreatment solutions, supplying commercial vehicle and engine manufacturers globally,” said Tim Jackson, Tenneco chief technology officer. “For more than 20 years, Cormetech has provided reliable state-of-the-art SCR catalyst for the reduction of NOx emissions.

The engine, an MAN B&W 6S46MC-C8 type capable of an output of almost 7 MW, was constructed in autumn 2010 by Hitachi Zosen Corporation at its Ariake works in southern Japan. The engine is bound for a general cargo carrier, to be built at the Nakai shipyard and scheduled to enter active service later this year. The vessel was ordered by Japanese customer,  BOT Lease Co. Ltd., and is operated by Nissho Shipping Co. Ltd. The first engine-start took place in January 2011. In connection with this…
