First sea trial of gas-to-liquids synthetic diesel onboard

  Feadship recently completed the first sea trial of gas-to-liquids synthetic diesel onboard Feadship Kiss. Gas-to-liquids (GTL) synthetic diesel, developed by Shell, proved to be a highly suitable energy carrier for the combined reformer/fuel cell installation envisioned for the year 2020. Shell’s large GTL facility in Qatar only started production in 2011, and pure GTL diesel fuel has only recently become available on the market. The Netherlands is a pioneer in this respect, and is leading the way with a worldwide introduction. The characteristics that make GTL an interesting option for conventional combustion engines originate in the way it is produced. Natural gas is broken down into syngas, from which all different GTL products are synthesised. As syngas contains very few contaminants, the resulting fuel is pure in its composition – free from sulphur, for instance – and gives a highly controllable burn. Another interesting factor is that syngas can also be generated by gasifying biomass, allowing for an operation that is close to CO2 neutral. An R&D project was set up on the recently launched Kiss to explore the possibility of switching to GTL as the fuel for all Feadship sea trials. One of the generators was run on GTL and ...

CAN: Emission reduction target difficult to meet

  EPD has released the latest Emission Inventory for 2013. It was showed in the Inventory that marine and road traffic has been the major sources of emission. Clean Air Network (CAN) believes more radical measures needed to be taken in order to reach the emission reduction target set for 2015. CAN is particularly concerned by the 4% increase in emission of nitrogen oxides (NOx) between 2010 and 2013. Queries have been raised on whether significant progress in reduction of emission could be made in the following two years, so that the target of reducing NOx reduction by 10% in 2015 could be met. Marine emission still accounted for 31% of NOx emission, which is the major contributing factor together with public electricity generation. In the latest paper on onshore power supply, the government suggested scrubber as a measure to reduce SO2 and PM from cruise ships. However, this technology cannot reduce NOx emission. CAN urges the government to employ onshore power supply to different cruise terminals and container terminal to effectively reduce NOx. Emission reduction 2013 and 2015 Recution Target  Marine transport continues to be the number one source of SO2 emission. The reduction in emission between 2010 and ...

VISEDO to Power Up World’s Largest Electric Ferry

  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.

Onshore power supply needed to protect public health

  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 ...

A look at LNG shipping

  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 ...

Emission Limits: Time to Act

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 ...
