In connection with the recent announcement of the construction of three wetfish trawlers for HB Grandi, the Icelandic fishing concern, MAN Diesel & Turbo has announced that the newbuildings’ MAN main engines will also feature its SCR (Selective Catalytic Reduction) system. The company states that the system will enable the trawlers’ IMO Tier II-compliant engines to fulfil the strict IMO Tier III NOx emission requirements. Vilhjalmur Vilhjalmsson, CEO of HB Grandi said: “When we decided to renew our fresh-fish fleet, we immediately focused on the task of curtailing the ships’ power requirements, both in terms of the propulsion plant as well as electricity production, so as to make the exhaust gas as clean as possible.” Vilhjalmsson added that HB Grandi deliberately pursues a green company profile and that its focus on clean and responsible fishing ultimately led to MAN technology being chosen for the trawlers. As such, HB Grandi’s profile suited the minimal environmental footprint from operations, including the cleaner exhaust gasses and NOx reduction that the MAN package offers. A further advantage of choosing MAN was the relatively straightforward integration of engine, propeller, propulsion controls and SCR system that equipment from the same manufacturer entails.

MAN Diesel & Turbo has announced the launch of its PA6 B Offshore GenSet (OG). Aimed at the offshore-drilling segment, the new engine is specifically targeted at semi-submersible drilling rigs. The PA6 B is a four-stroke, medium-speed engine built at MAN Diesel & Turbo’s St. Nazaire, France facility from where the company has successfully sold the engine for many years. St. Nazaire will assemble individual PA6 B OG units together with an alternator in constructing the new, offshore GenSets. Typically, 8 × 16PA6 B OG units are installed aboard a semi-submersible both for main and emergency power supply. In developing the new OG-variant, the original PA6 B engine has been much adapted to meet current market demands. One major innovation has been on the emissions front with the result that the PA6 B OG is now Tier II-compliant and can also meet Tier III regulations with the SCR (Selective Catalytic Reduction) technique. Another key development is that the PA6 B OG now employs SaCoSone, MAN Diesel & Turbo’s proven engine-safety-and-control system, while the range of turbochargers suitable for operation with the new engine has accordingly been updated. The PA6 B OG is a compact, lightweight, and robust powerhouse with low ...

MAN PrimeServ, MAN Diesel & Turbo’s service division, has announced the 100th sale of its PMI (Pressure Measuring Instrument) Auto-tuning retrofit package. The ‘MSC Filippa’, a 2011-built, 13,400-teu container ship owned by Germany’s Peter Döhle Group, will be retrofitted to accommodate the system. Hagen Koslowski, Technical Director of Peter Döhle Schiffahrts-KG, said: “The main driver for us in ordering PMI Auto-tuning was to reduce fuel consumption and therefore become more attractive to the charter market. Taking a broader view, the CO2 reduction and our environmental responsibility, paired with our trust in MAN products, also played key roles in the decision.” The Peter Döhle Group has previous experience with PMI Auto-tuning, having recently installed it aboard a series of 6,800-teu vessels – MV ‘Pangal’, MV ‘Puelche’ and MV ‘Petrohue’ – equipped with MAN B&W 10K98MEC-7 low-speed engines. Of their experience with this, Koslowski said: “On all our vessels, the system runs reliably. The PMI works really well and adjustments can be seen on the CoCoS computer and MOP, while engine parameters are always at the optimal value.” Koslowski also praised an “outstanding performance” by MAN PrimeServ’s service engineers who installed, commissioned and pre-adjusted the PMI Auto-tuning system aboard the container fleet. ...

Hitachi Zosen Corporation has become the first to receive first-time approval (FTA) for an SCR system (Selective Catalytic Reduction system) for marine engines from its licensor MAN Diesel & Turbo SE, in the field of the design and manufacturing of marine diesel engines. The International Maritime Organization (IMO) proposed the standards on the reduction of nitrogen oxide (NOx) and sulfur oxide (SOx) emissions during maritime transportation. In April 2014 The IMO Marine Environment Protection Committee adopted stringent Tier III controls twhich require an 80% reduction of NOx emissions from Tier I (17.0 g/kWh) to be effective within emission control areas (ECA) from 2016. Hitachi Zosen in partnership with MAN, its licensor boasting a more than 80% global share in the marine diesel engine market, embarked to develop a SCR system for marine engines using Hitachi Zosen’s proprietary NOx removal catalyst and system into test engine in 2009. In 2011 the SCR system was certified by Nippon Kaiji Kyokai (NK: Japan Maritime Association) ahead of the competition and fitted in a new vessel for in-service testing ongoing for three years from November 2011. The FTA from MAN verified that Hitachi Zosen’s SCR system for marine engines is fully compliant with Tier ...

United European Car Carriers (UECC) has signed a contract for the construction of two LNG-powered car carriers (PCTCs). A single MAN B&W 8S50ME-GI dual-fuel engine will power each newbuilding. The PCTCs will be capable of operating on LNG fuel, heavy fuel oil or marine gas oil, providing greater flexibility and efficiency. They represent the first such vessels globally to be fitted with an LNG propulsion system. When in service, they will be capable of completing a fourteen-day round trip in the Baltic operating solely on LNG, including main engine and auxiliary power generation. UECC ordered the newbuildings in conjunction with a long-term fleet evaluation process concerning its Baltic fleet. Among the key requirements for new tonnage was an ability to meet all expected environmental legislation (SECA). In this respect, LNG is recognised as the cleanest and most environmentally friendly choice of fuel suitable for marine transport. LNG fuel significantly reduces CO2 and NOx emissions, as well as almost entirely eliminating oxides of sulphur (SOx) and particulate emissions. To this end, UECC has signed an exclusive contract for the supply of LNG fuels to the vessels in the port of Zeebrugge using a dedicated LNG ship-to-ship bunker vessel. The vessels will ...

The HERCULES R&D programme to develop large engine technologies, which was initiated in 2004 as a joint vision by the two major European engine manufacturing groups, Wärtsilä and MAN Diesel & Turbo, is to continue with a new HERCULES-2 project, pending approval under the Horizon 2020 EU Framework Programme for Research and Innovation. The HERCULES-2 project is aimed at developing a fuel-flexible marine engine that is optimally adaptive to its operating environment. The work will focus on four areas of integrated R&D divided into Work Package Groups (WPG), as follows: WPG 1 - a fuel flexible engine; WPG II - new materials (for engine applications); WPG III - an adaptive powerplant for lifetime performance; and WPG IV - a near zero emissions engine. This work will build upon and surpass the targets of the previous HERCULES projects by going beyond the limits set by the regulatory authorities. By combining the very latest technologies, and through the use of integrated solutions, the new project aims to achieve significant reductions in fuel consumption and exhaust emissions. The project includes several full-scale prototypes and shipboard demonstrators that will speed the development of commercially available products. This co-operation between Wärtsilä and MAN Diesel & ...

MAN Diesel & Turbo has been awarded a Tier III-compatibility certificate by the DNV-GL classification society for MAN 8L21/31 four-stroke engine aboard a DFDS Seaways ship with a retrofitted SCR (Selective Catalytic Reduction) system. While the engine alone meets IMO Tier II emission criteria, the SCR system for NOx reduction raises the whole system to the standard demanded by IMO Tier III rules. The vessel in question, the ‘Petunia Seaways' is a cargo ship that sails a regular North Sea route between Gothenburg, and Immingham, respectively Ghent for DFDS Seaways. Its SCR system greatly reduces the level of nitrogen oxides (NOx) from the engine's exhaust gas. Since September 2012, when one of Petunia Seaways' 8L21/31 auxiliary engines was retrofitted with a SCR system, it has played a major role in the testing of this new technology. As such, the system has proven daily that freight ships can now meet the strict emission levels laid down by IMO Tier III where NOx emissions have to be reduced in certain areas by 75% compared to current limits. "For the last 8,800 hours, this particular auxiliary engine of the Petunia Seaways has consistently met Tier III NOx limits under real life operating conditions ...
