Megastar Bunkering Experiences MEGASTAR BUNKERING EXPERIENCES Sergei Jefimov Klaipeda 15.11.2017 CONTENTS 1. Eesti Gaas in brief 2. Why LNG? 3. Bunkering of Megastar 4. LNG supply chain 5. LNG quality 6. Conclusion EESTI GAAS IN BRIEF 1. The oldest estonian energy company, roots in 1948. 2. Sale of natural gas, electricity, CNG (8 stations) and LNG. 3. Owner of the largest gas distribution network in Estonia (1 500 km). 4. Two subsidiary companies: - Gaasivõrgud (gas distribution service), - EG Ehitus (construction and renovation of gas-, heat-, and water distribution networks). 5. Revenue of EUR 116 million in 2016. 6. 217 employees (10.11.2017). INFORTAR bought out the Eesti Gaas from Fortum, Gazprom and Itera in April 2016. WHY LNG? WHAT IS LNG? • LNG - liquefied natural gas • LNG consists of up to 98% of methane, which has been cooled down to the liquefying temperature of -162°C (and ambient pressure). • The volume of natural gas is reduced during liquefaction by approximately 600 times. • LNG is used in maritime and road transport, as well as energy production • LNG is used either as is (in transport) or it is regasified prior to injection into the gas distribution network. WHY LNG? • According to the protocol of IMO with MARPOL and EU Directive 1999/32/EC, EU Member States have to ensure that ships in the Baltic, the North Sea and the English Channel are using fuels with a sulphur content of no more than 0.10% starting from 2015 (SECA) • This regulation creates gradually significant market for LNG as marine fuel. LNG VERSUS HFO LNG KEEPS ON GROWING IN MARITIME INDUSTRY BUNKERING OF MEGASTAR MEGASTAR - THE NEWEST LNG FERRY Built in: Meyer Turku Shipyard Gross tonnage: 49 000 Length: 212 meters LNG powered fast ferry for the Tallinn - Helsinki shuttle service Capacity: 2800 passengers, 800 cars Engine: Dual fuel (LNG/MGO) Service speed: 27 knots The vessel cost is app. EUR 230 million Production of the vessel started on 4th of August 2015.

Pre-bunkering actions 2. Bunkering procedure 3. Post-bunkering actions 1. PRE-BUNKERING ACTIONS • Parking of semi-trailers • Marking the safety zone with cones • Connecting ESD and earthing cables • Blocking the trucks wheels • Covering the opened hatches • Electricity is turned off in the safety zone 1. PRE-BUNKERING ACTIONS • Filling the check-list • Connecting and inerting/purging the hoses • Pressure and leak test of the whole system • Cooling down of pump • Increase the pressure in the semi-trailer 2. BUNKERING PROCEDURE • Duration of bunkering 4 times a week between 2-6 a.m. • 3-4 trucks per night 3. POST-BUNKERING ACTIONS • Purging the hoses and system with nitrogen • Disconnecting hoses • Repeal the safety zone • Departure of trailers • Final filling of check-list, CMR and custom doc. All operations before, during and after bunker activities will be carried out in accordance with the check-list. DCC CONNECTIONS – ONE STANDARD • Easy to handle Push and turn – free flow Turn and pull – closed. • Safe The valve cannot be opened until the unit is coupled and closes automatically when disconnecting. • Environmentally friendly Accidental spillage eliminated • Reliability No loss or spillage of liquids at connection and disconnection SAFETY PPE • The personnel wear special work clothes and portable gas detectors LNG QUALITY LNG QUALITY FOR BUNKERING Тemperature ≤ -155 oC Pressure ≤ 1.5 bar The provider undertakes, Propane ≤ 1.5% Mol warrants and quarantees Nitrogen ≤ 0.8% Mol that each shipment of LNG Carbon ≤ 0.006% Mol dioxide (СО2) meets the following Ethane ≤ 7.0% Mol parameters at the point of Methane ≥ 90% Mol delivery. Methane number ≥ 80 Density ≥ 420 kg/m3 Oil content, heavy Not allowed hydrocarbon condensate RISK OF DELIVERING „OFF SPEC“ LNG A key issue in LNG transportation is the generation of Boil-Off Gas (BOG). The “boil-off” of the volatile components in the LNG stored leads to a change in composition of LNG. BUNKERING PIONEERING Film Bunkering Pioneering 500.mp4 More than 500 bunkering operations sucessfully done by 30.01.2017! CONCLUSION 1. EG has got unic experience to do TTS LNG bunkering. 2.

  • Energy Policies Beyond IEA Countries
    Estonia 2013 Please note that this PDF is subject to specific restrictions that limit its use and distribution. The terms and conditions are available online at http://www.iea.org/ termsandconditionsuseandcopyright/ 2013 Energy Policies OECD/IEA, © Beyond IEA Countries Energy Policies Beyond IEA Countries Estonia 2013 One of the fastest-growing economies in the OECD, Estonia is actively seeking to reduce the intensity of its energy system. Many of these efforts are focused on oil shale, which the country has been using for almost a century and which meets 70% of its energy demand. While it provides a large degree of energy security, oil shale is highly carbon-intensive. The government is seeking to lessen the negative environmental impact by phasing out old power plants and developing new technologies to reduce significantly CO2 emissions. The efforts on oil shale complement Estonia’s solid track record of modernising its overall energy system. Since restoring its independence in 1991, Estonia has fully liberalised its electricity and gas markets and attained most national energy policy targets and commitments for 2020. It has also started preparing its energy strategy to 2030, with an outlook to 2050. Estonia is also promoting energy market integration with neighbouring EU member states. The strengthening of the Baltic electricity market and its timely integration with the Nordic market, as well as the establishment of a regional gas market, are therefore key priorities for Estonia. Following its accession to the Organisation for Economic Co-operation and Development (OECD) in 2010, Estonia applied for International Energy Agency (IEA) membership in 2011.

  • EPRG Working Paper 1009
    Gas Supply Security in the Baltic States: A Qualitative Assessment EPRG Working Paper 1009 Sachi Findlater and Pierre Noël Abstract In a setting of increasing European concern over gas supply security, this article provides an empirical assessment of the gas supply security situations of three of the most gas dependant nations in Europe: Latvia, Lithuania and Estonia. The analysis challenges existing security indices and places an emphasis on having a detailed understanding of a country’s specific gas supply set up, the structure of its gas consumption and, in particular, policies in place designed to mitigate the effects of a disruption. Keywords Natural Gas, security of supply, Baltic States JEL Classification Q40, Q48 Contact [email protected] Publication March 2010 EPRG WORKING PAPER Financial Support EPSRC www.eprg.group.cam.ac.uk Gas Supply Security in the Baltic States: A Qualitative Assessment Sachi Findlater1 and Pierre Noël Electricity Policy Research Group (EPRG), University of Cambridge March 2010 . 1. The context Energy security has been moving up the European policy agenda over the last decade, recently becoming a prominent theme of the European political debate. This has been driven largely, though not entirely, by the rise in concern about the security of natural gas supply to Europe, particularly supplies from Russia. The crises of January 2006, and especially January 2009, where supplies of Russian gas to Europe via Ukraine were entirely disrupted for two weeks in the middle of a cold winter, have been key milestones in this process. The three Baltic States (Estonia, Latvia and Lithuania) were not impacted by the crisis of January 2009 as none of them rely on transit through Ukraine for their gas imports.

  • Increasing Role of Underground Gas Storages
    23rd World Gas Conference, Amsterdam 2006 INCREASING ROLE OF UNDERGROUND GAS STORAGES FOR RELIABE SUPPLY OF GAS TO LATVIA, LITHUANIA, ESTONIA, FINLAND AND NW RUSSIA AND PROSPECTS OF DEVELOPMENT OF INCUKALNS UNDERGROUND GAS STORAGE Dr.sc.ing A. Davis, M.sc. ing. A. Jesinska, Joint Stock Company “Latvijas gaze” Prof., Dr.habil. Sc. ing. Andris Kreslins, Riga Technical University Prof., Dr.habil. sc. ing. V. Zebergs, Prof., Dr. habil. sc. ing. N. Zeltins, Institute of Physical Energetics of Latvian Academy of Science Latvia ABSTRACT According to the estimates done by specialists of OAO “Giprospecgaz”, daughter company of OAO “ Gazprom”, in their feasibility study regarding regional development of gas supply system in Baltic Countries, Northwest Russia and Finland, needs for natural gas will reach in year 2015 in Latvia 2.8.10 9m3, Lithuania 5.25, Estonia 1.3 10 9m3, Finland 6.0710 9m3 and Russia 39.9810 9m3. Total gas demand of this region in year 2015 will reach 39.98. 10 9m3, and in year 2020 even 41.76. 10 9m3. At the same time, due to the fact that natural gas in the region is and according to prognosis will be extensively used for heating purposes, huge difference between gas consumption in summer and winter will remain, and, for example in 2015 monthly consumption of gas in July, according to the forecasts, will be only 36% of the one in January. In our opinion, potential of Latvian underground gas storages can be well used to meet increasing and changing demands for natural gas in the region and, therefore, Joint Stock Company “ Latvijas Gaze”, which owns and operates Incukalns Underground Gas Storage in Latvia, currently with the active gas volume of 2.3.
