Standard Club: LNG as a marine fuel

  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 ...

New initiative improves shipping's safety record

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 ...

Yara fights emissions at sea

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.

Shipping must remain energy-efficiency in a low crude price environment

Ship efficiency remains just as relevant and important in a bearish oil market as it does when shipowners have to pay over US$600 for a tonne of Heavy Fuel Oil. “With crude oil prices at their lowest since April 2009, the temptation is to put your foot on the gas and speed up a bit but this is not the way forward. When oil prices are low shipowners can benefit more fully from energy-saving technologies,” said Hakan Ozcan, the Chief Financial Officer of Ecoships, the technical ship management arm of Newport Shipping Group, “Admittedly bunker fuel will continue to be the largest single operational cost for shipowners, but with fuel prices continuing to drop, profit and loss accounts will improve, providing owners with the resources needed to re-invest in new ship designs, equipment and technologies capable of reducing fuel consumption even further. It’s a win-win situation for the merchant fleet.” Whilst Ozcan does not suggest that the industry embarks on the kind of newbuilding spending spree that will prolong or perpetuate over-capacity, he does believe shipowners have a commercially-viable opportunity to replace ageing, less efficient tonnage with vessels capable of meeting increasingly stringent environmental regulations. “It just makes economic sense. ...

Most shipping emissions in ports to quadruple by 2050

According to "Shipping Emissions in Ports" report, issued by International Transport Forum (ITF), shipping emissions in ports are substantial, accounting for 18 million tonnes of CO2 emissions, 0.4 million tonnes of NOx, 0.2 million of SOx and 0.03 million tonnes of PM10 in 2011. Around 85% of emissions come from containerships and tankers. Containerships have short port stays, but high emissions during these stays. Most of CO2 emissions in ports from shipping are in Asia and Europe (58%), but this share is low compared to their share of port calls (70%). European ports have much less emissions of SOx (5%) and PM (7%) than their share of port calls (22%), which can be explained by the EU regulation to use low sulphur fuels at berth. The ports with the largest absolute emission levels due to shipping are Singapore, Hong Kong (China), Tianjin (China) and Port Klang (Malaysia). The distribution of shipping emissions in ports is skewed: the ten ports with largest emissions represent 19% of total CO2 emissions in ports and 22% of SOx emissions. The port with the lowest relative CO2 emissions (emissions per ship call) is Kitakyushu (Japan); the port of Kyllini (Greece) has the lowest SOx emissions. ...

EU Parliament passes law to make ships report climate emissions

For the first time, all shipping companies calling at EU ports will have to measure and publicly report carbon emissions under a law approved by an overwhelming majority of the EU Parliament's Environment Committee. Sustainable transport group Transport & Environment (T&E) says that the law is weak - it only monitors fuel consumption instead of directly reducing it, and only covers CO2 and not air pollutants like SO2 or NOx - but it can still trigger fuel savings indirectly. The EU law will require ship operators to publicly report three metrics to measure the environmental performance of ships: the theoretical energy performance of the ship known as the Energy Efficiency Design Index (EEDI); its real-world fuel consumption; and its energy efficiency, that is, the amount of fuel divided by the amount of cargo. The more cargo a ship can carry using the same amount of fuel, the more efficient and cheaper to run it is. The publication of ships' real energy efficiency will provide shipping users in Europe and worldwide with transparent data to identify the most efficient ships and practices. This can trigger a virtuous cycle of increased competition among operators, which will enable fuel savings and emissions reductions. ...

World’s first low emission gas carriers to cut the environmental impact of chemical transport

Two new liquefied natural gas (LNG) powered sea vessels have recently been named on Teesside .  Operated by ship owner Anthony Veder, the new ships will carry Liquefied Ethylene Gas (LEG) from SABIC’s Wilton facility on Teesside to manufacturing plants in North-West Europe and Scandinavia.  The chemicals will be used to make a range of everyday items such as food packaging, PVC, detergents and adhesives.  The state of the art ships will drastically cut both sulphur oxides (SOx) and nitrogen oxides (NOx) emissions compared to the vessels they are replacing.  Switching to alternative fuels for ships, such as LNG, instead of traditional fuel oils is one of the solutions identified by Anthony Veder to help SABIC further improve its environmental performance.  “As a responsible global company, SABIC is committed to providing high-quality products to its customers while doing all it reasonably can in order to reduce the environmental impact of its operations,” said SABIC’s European Supply Chain Director of Chemicals Wouter Vermijs while attending the naming ceremony.  “We are proud to be the first chemical company in the world to be transporting our products on carriers running on LNG and to have an innovative partner in Anthony Veder.” The new ...

Technology to help maritime industry meet emission standards

Commissioned by TCC Group, researchers at the University of Southern California (USC) Viterbi School of Engineering have made exciting progress in developing a more efficient method to initiate combustion, providing a breakthrough, technological step forward in clean shipping design. The technology, Transient Plasma Ignition (TPI), would allow marine diesel ships to reduce emissions, increase fuel economy and meet the International Maritime Organization's (IMO) stringent emissions mandate with minimal modifications. "We are thrilled to approach the cusp of a true clean shipping solution, especially on the heels of the recent United Nations Climate Summit," said Kenneth Koo, TCC Group chairman. "This epic endeavor strives to achieve reduction in harmful emissions and significant fuel consumption savings without additional investments into peripheral hardware such as scrubbers, chillers, hull coatings or fundamental modifications to the hull. It will be an immense boon for the shipping industry." TPI facilitates combustion by using energetic electrons that break the molecular bonds in fuel and air creating an alternate chemistry. This new environment allows for a more complete combustion, minimizing the amount of remaining unburned hydrocarbons, which translates to significant fuel savings and reduced emissions. TPI – Reversing Efficiency Losses, Recovering Energy & Reducing Emissions The technology aims ...
