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. In operation since 30th of January 2017 LOCATION OF MEGASTAR BUNKERING Estonia, Port of Tallinn, Quay No 5 HIGHEST BUNKERING SAFETY STANDARDS • Preparation – HAZID, HAZOP and QRA • All applicable standards are met (ISO 20519:2017) • Technical safety: • Trailer tanks with highest level of insulation • Duplicated protection from overpressure • Emergency Shut-Down (ESD) protection • Break-Away-Couplings (BAC) protection • Dry Crygenic Couplings (DCC) HIGHEST BUNKERING SAFETY STANDARDS • Operational Safety: • Safety zones are evaluated according to risk assessment • 0-emission operations – only DCC are used • Full set of PPE is worn by every driver-operator • Bunkering school - multistage training and examination of bunkering driver-operators LNG TRAINING PROGRAMM THEORY I LNG-TRAINING Emergency response THEORY II ASSISTED BUNKERING TRAINING THEORY III UNTILL EXAME COMFORT LEVEL REACHED Trained Bunkering Operator Training certificate Signed Sergei Danilov logbook Issue date: 10.02.2017 Approved by: Valid date: 10.02.2018 Sergei Jefimov SECURITY AND SAFETY ZONES • Safety zone – area around the bunkering station where only dedicated and essential personnel and activities are allowed during bunkering • Security zone – area around the bunkering station and ship where ship traffic and ohter activities are monitored (and controlled) to mitigate harmful effects. LNG SUPPLY CHAIN SOURCES OF LNG Porvoo Hamina • There are several LNG import- export terminals/production in the region and on the coast of Paldiski Muuga Baltic Sea. in operation Skulte planned LNG SUPPLIES • Eesti Gaas supplies LNG mainly from the Pskov liquefaction plant (2x350 km, 24-36h) • Some supplies has made from Pori (Finland) and Świnoujście (Poland) terminals LNG SEMI-TRAILERS FLEET • Eesti Gaas has 8 modern semi-trailers from GOFA in order to transport and bunker LNG • The semi-trailers have powerful Cryostar 1000 l/min cryogenic pumps TRUCK-TO-SHIP (TTS) BUNKERING Truck-to-ship bunkering - typical arrangement of LNG fuelled ship with type C tank TTS BUNKERING • Available everywhere (in all harbours) Flexibility • Flexible to logistics solution • Flexible to operate • Volumes - not more than 200 m3 per bunkering Limited • Flow rates 60 -120 m3/h • Used at a distance from the source of LNG to 500-600 km • Relatively small investments (CAPEX) Inexpensive • Competitive logistic price MAIN STEPS OF TTS BUNKERING 1. 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. EG is ready to offer TTS bunkering to other harbours in the region. A lot of LNG ships are coming – a lot of opportunities for all! THANK YOU! Sergei Jefimov AS Eesti Gaas [email protected].
