  The Finnish electric drive train specialist VISEDO has been selected as the sole electric-system supplier for the world's largest fully electric ferryboat to be built by the Danish shipbuilder Søby Shipyard Ltd. The ferry will be introduced in June, 2017 to transportation of vehicles and passengers between the island Ærø and the mainland in Denmark. The Finnish ground-breaking innovative electric drive specialist was preferred over the industry giant Siemens which was the previous candidate for the delivery. As one of the Top 5 projects in the EU Horizon 2020 initiative, a program with a total budget of 21 million euros, this initiative is part of the Danish Natura project, which guarantees local people green transportation in these areas. The ferry will be a state-of-the-art design and will achieve efficiency gains by optimizing weight by integrating lighter materials and equipment. It will reduce the CO2 emission by 2000 tons and NOx emissions by 41,500 kg per year. The silent electric propulsion system from Visedo will also reduce the emitted noise level compared to diesel engine operation. In addition, the vessel will reduce wake waves right behind the ferry by 60-70% and it will be able to navigate in the EU ...

  The government of Hong Kong has released the administration’s paper on “Provision of on-shore power supply at Kai Tak Cruise Terminal” to the LegCo. Clean Air Network (CAN) stated its disappointment that the authorities has decided to shelve the installation of onshore power supply for Kai Tak Cruise Terminal. According to the 2012 Emission Inventory for Hong Kong published by the Environmental Protection Department, ocean going ships became the number one source of respirable suspended particulates, nitrogen oxides and sulphur dioxide in Hong Kong. Cruise ships accounted for 2.4% of SO2, 0.9% of NOX and 1.5% of PM respectively. As estimated by Hedley Environmental Index, in 2014, air pollution caused 2,616 premature deaths and 32.657 billion in lost dollars. Thus, we can calculate that by installing onshore power supply, the death number could be reduced by 42 and 523 million could be gained annually Clean Air Network CEO Sum Yin Kwong says, “The government tends to calculate cost benefits without considering external social costs. Comparing similar community projects such as spending 600 million for a gymnasium, the building of onshore power facilities is certainly worthwhile in order to protect public health.” In the paper, it is estimated that the growth ...

  Tenneco introduced  its large engine selective catalytic reduction (SCR) system for marine applications. The system features an integrated soot blower option, which ensures effectiveness of NOx reduction and overall catalyst performance when high sulphur fuels are used or engines operate at low exhaust temperature levels. Tenneco’s SCR aftertreatment system features a complete dosing control solution specifically designed for marine engine applications up to 7,500 kW or 10,000 hp. The system enables auxiliary and propulsion engines to meet EPA Tier IV and IMO Tier III regulatory requirements and provides precise and reliable delivery of liquid urea via a proprietary, high-performance injector design, a precision mechatronic fluid delivery pump, and customizable remote monitoring and controls. The integrated soot blower is designed for use with a range of high-sulfur fuels, including marine diesel oil (MDO), and heavy fuel oil (HFO),  and enables the SCR aftertreatment system to deliver consistent emissions reduction performance by preventing ash and soot from blocking  the catalyst. The result is more effective NOx reduction and overall catalyst performance over the life of the system “We’re committed to developing diesel engine aftertreatment solutions that meet important marine regulatory requirements and deliver the performance expectations of global marine market customers,” said ...

  Worldwide sourcing and distribution of LNG has grown into a major industry player while seeking to balance the growing global appetite for affordable energy with environmental concerns.  MAN Turbo and Diesel created an infographic regarding LNG shipping which is a booming market, driving growth at every stage of the process chain. Lower emissions Natural gas burns far cleaner than other fossil fuels do, producing 30% less carbon dioxide than petroleum and 45% less than coal, as well as significantly lower levels of sulfur and nitrogen oxides. “Natural gas and air are mixed before entering the combustion chamber and ignited via a small quantity of injected MDO/MGO pilot fuel. The combustion process according to the Otto-cycle ensures the lowest nitrous oxide (NOx) emissions when operating in gas mode, which are lower than projected future emission limits. For the sake of fuel flexibility, the engine can operate alternatively in liquid mode, where fuel oil is injected via conventional main pumps as in the 48/60B HFO engine,” explains Dietmar Zutt, Head of Sales Merchant Marine at MAN Diesel & Turbo. A booming market The booming LNG market is driving more than ship production, however. There is significant growth and investment at every stage ...

Image Credit: DNV GL - Maritime Update Issue 01-15, page 53 (Click to enlarge picture)  The challenges for the shipping industry are not getting any easier. New emission limits, while not coming unexpectedly, require substantial investments in technology; and time is running out. A look at the available options The shipping industry has been going through turbulent times. For a sector accustomed to planning decades ahead, the sequence of unexpected major events, from the financial crisis to depressed freight and charter rates, and from dropping fossil fuel prices to new international tensions, has certainly added plenty of headache to investment decisions. Many shipowners delayed investing in new anti-pollution technology hoping for a clearer field of vision, while others took action early to gain competitive advantage. With new sulphur limits now in force for European Emission Control Areas (ECAs), and the North American and US Caribbean Sea ECAs also regulating NOX and PM, those who chose to wait must act now. Further regulations will take effect soon, and additional regional and national regimes are emerging around the globe (refer to info box). Investing now will save shipowners money and protect their reputation. However, the substantial capital requirement, a lack of mature technology and uncertainty regarding compliance documentation add to the complexity of this decision. The IMO’s new ECA regulations, in effect for Northern Europe and ...

Mitsubishi Heavy Industries Marine Machinery & Engine (MHI-MME) released UE Engine Technical Data on its website. The new Technical Data can be browsed and downloaded from the company's website. The new search system, which complies with IMO NOx Tier III regulations, is designed to provide a broad range of useful information to our customers planning new vessels with UE engine. Formerly, MHI-MME shared the UE Engine Technical Data which comply with IMO NOx Tier II regulations, with a limited number of customers on the dedicated website. However, in order to provide better user-friendliness, MHI-MME renewed the system for IMO NOx Tier III compatible engines by improving the format, contents or design, and released the data widely on the website. At this moment, the data for two engine types, UEC50LSH-Eco-C2 and UEC45LSE-Eco-B2, are released to the public. Furthermore, MHI-MME is planning to release the data for all UE Engines that are control subjects of the IMO NOx Tier III regulations, on the website by the end of 2016. Meanwhile, MHI-MME will continue to provide the Technical Data which comply the IMO NOx Tier II through the existing dedicated site. On the strength of this renewal of UE Technical Engine Site, MHI-MME ...

  The Standard P&IClub issued an article outlining club's considerations regarding LNG (Liquefied Natural Gas) as a marine fuel. Compared to road transportation, inland shipping has been considered to have a lower carbon footprint. Since January 2011, EU regulations have required low sulphur fuel for inland shipping, but the next raft of regulations is for emission reductions for nitrous oxides (NOx) and particulate matter (PM). As an interim step towards zero emission fuels, LNG has come out as a valuable solution. Coupled with investment for LNG bunkering infrastructure in North Europe, it is becoming more commercially and economically viable and the first LNG inland ships have started operating. LNG powered ships is not new technology. The LNG tanker fleet has used boil off gas since the 1980’s. LNG tankers have a good safety record and are designed and operated within established IMO regulations and recommendations: IGC – Safe Carriage by Sea of Bulk Liquefied Gasses; Resolution MSC 285(86) Interim Guidelines on Safety for Natural Gas-Fuelled Engine Installations in Ships (2009); and the recently accepted draft “International Code for Ships using Gas or other Low Flash-point Fuels” (IGF Code) Rules and regulations For ships operating on the European inland waterways, mostly the ...

Dr Pierre C. Sames from DNV GL introduced the Vessels for the Future initiative at the European Shipping Week in Brussels Looking ahead to 2020 and beyond, both maritime and inland waterways will be under ever increasing pressure, as we use them for transport, recreation and commercially. At European Shipping week (ESW), Dr Pierre C. Sames, Chairman of the European Research Association and Director of Maritime Technology, Research and Development at classification society DNV GL, introduced a new initiative - Vessels for the Future - which aims to improve shipping's safety record, sustainability and global competitiveness. Launched in November 2014, over 50 companies, research institutes, academic organizations and interested associations have already signed up to take part in the initiative to work towards a more sustainable European transport system. "Aiming at a private public partnership is important not only as it allows us to have a coordinated research, development and implementation (RDI) programme which covers both vessels and waterborne operations, but it demonstrates a clear commitment from all stakeholders to meet the ambitious goals of the initiative," said Dr Sames. The initiative focuses on the three key areas for the maritime transport cluster: safe and efficient waterborne transport and competitiveness ...

Commercial ships are heavy emitters of harmful nitrogen oxides NOx and sulphur oxides (SOx). These exhaust gases are created when burning fossil fuels. They have negative consequences for our health (asthma) and the environment (acid rain). Yara has over the past years expanded its emissions to air (E2A) portfolio through a combination of innovation projects and acquisitions.The acquisitions of H+H and Green Tech Marine enabled Yara to become a total solution provider for both NOx and SOx emissions at sea. They provide Yara with technology uniqueness. H+H is the market leader in marine NOx reduction technology, while Yara Marine Technologies (formerly Green Tech Marine) has developed an innovative high-performance and energy-saving solution for reducing the SOx emissions in the maritime and offshore industries. The smallest scrubber in the market make it easy to retrofit any seagoing vessel by simply replacing ship’s exhaust silencer without the need of structural modifications. As a consequence the installation and commissioning of the scrubber can even be done while sailing. Yara is taking steps to improve on  internal emissions and a good example for that is the new ammonia ships, which will be equipped with Yara's emissions control technology.
