DNV GL has issued statutory alert to remind that IMO NOx Tier III requirements will take effect in the North American and US Caribbean Emission Control Areas (ECAs) from January 1st 2016. The new requirements are applicable to all vessels with keel-laying on or after January 1st 2016 with an engine output of ≥130kW. DNV GL highlights that it is important to be aware of how to prove compliance and how the requirements will be enforced.

The slow steaming practice resutls in fuel saving and cuts in nitrogen oxides (NOx) emissions

EU Commission plans for more ambitious national caps on emissions of six key pollutants, including NOx, particulates and sulphur dioxide, were endorsed by Parliament. Air pollution causes about 400,000 premature deaths in the EU yearly, and the plans could save up to €40bn in air pollution costs by 2030.“Air pollution imposes enormous human and economic costs. It also damages the natural environment, through eutrophication and acid deposition, and it doesn’t stop at EU member states’ borders”, said lead MEP Julie Girling (ECR, UK). Her report was approved by a show of hands.“This legislation will help at all levels of governance in the member states, including the regional and sub-regional authorities who have engaged so vigorously in the process. There is a real bottom-up demand for action”, she added.“My report also pushes the Commission to ensure that the Real Drive Emissions (RDE) procedure is agreed on as soon as possible. We all agree that NOx must be dealt with urgently. The public are demanding action in this area following the recent revelations on the car industry”, she concluded.More ambitious capsMEPs approved the proposed caps for sulphur dioxide (SO2), nitrogen oxides (NOx), non-methane volatile organic compounds (NMVOC), methane (CH4) ammonia (NH3), and ...

 DNV GL has issued Statutory News regarding the upcoming environmental regulations for emissions to air.The IMO Tier III requirements reduce nitrogen-oxide emissions (NOx) by approximately 76% in comparison to a Tier II engine. This requirement only applies to new vessels and engines. It poses a significant challenge to engine designers, as they need to apply NOx-reduction measures with the help of other engine technologies.Relevant for all vessels with keel-laying on or after 1 January 2016 with engine output of 130kW and above, when operating in North American and US Caribbean Sea Emission Control Areas.The IMO NOx-emission limits apply to diesel engines and depend on an engine’s maximum operating speed (n, rpm), as presented in the table below. Tier I and Tier II are global requirements, whereas Tier III standards only apply to current existing Emission Control Areas (ECAs) for NOx (North American and US Caribbean Sea).In future ECAs that regulate NOx emissions, the Tier III standards will apply to ships with keel-laying on or after the date of adoption of such an ECA.When the global Tier II limits came into force in 2011, engine-makers were able to tune the engines to comply with these new emissions limits. Tier III poses ...

  The Fairplay Towage shipping company officially launched a new harbour tug featuring diesel gensets certified to IMO Tier III in Rotterdam on 10 July 2015. Powered by MTU Series 4000 engines featuring an SCR exhaust aftertreatment system, these diesel gensets are some of the first gensets in the world already certified as complying with IMO Tier III emission levels which come into force in 2016. Rolls-Royce delivered the two MTU 16V 4000 M63L main propulsion engines, each delivering 2,000 kW, one Series 4000 M23F 16-cylinder diesel genset with 1,520 kW and the MTU-developed SCR system. The exhaust aftertreatment system featuring selective catalytic reduction technology is combined with the diesel genset. MTU is a Rolls-Royce Power Systems brand which belongs to the Land & Sea Division of Rolls-Royce. “We're rather proud of being able to demonstrate the capabilities of this pre-series, space-saving solution to our client in the course of these trials”, says Nadine Buhmann, Head of Marine & Offshore Business at MTU. With trials in the Fairplay tug lasting some 10,000 hours, MTU is advancing its series solution for IMO Tier III marine engines. As of 2016, new vessels operating in the so-called Emission Control Areas off the North ...

  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 ...

Parker Procal, part of the Parker Hannifin Corporation and the supplier of Continuous Emissions Monitoring Systems (CEMS) for marine applications, has announced that its Procal 2000 emissions analyser has been certified by DNV-GL having met the requirements of MEPC 184(59) Chapter 6 on emission testing of CO2 and SO2, as well as the requirements of the revised MARPOL Annex VI and NOx Technical Code 2008. The certification of the analyser aids ship owners in providing robust evidence to demonstrate compliance with ECA regulations. The Procal 2000 is an in-situ analyser which analyses the gases from the combustion of residual and distillate fuel. It also measures the water content of the exhaust so that CO2 and SO2 can be reported on both a wet and a dry basis, demonstrating compliance with ECA regulations in port and in international waters. To achieve certification, the Procal 2000 analyser was rigorously tested to prove the effective measurement of emissions required to determine compliance with the updated MEPC 184(59) Chapter 6 and Marpol Annex IV and NOx Technical Code 2008 regulations. Changes to these regulations include updates on the measurement of CO2 and SO2, the testing of NOx emissions in gas and dual-fuel engines, calculation ...

  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 ...

  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 ...
