2 IGF Code update

3 Rules & Standards overview for ship design IGF Code 3

4 Rules & Standards overview for LNG as fuel LNG Supply Facilities LNG Bunkering Facilities Receiving Ship ESD ESD Standards and regulations for shore facilities EN 1473/13645 ISO Onshore supply Onshore mobile supply Offshore supply Shore -to-ship bunkering Truck-to-ship bunkering Ship-to-ship bunkering IGF Code 4

5 Scope of IGF Code Address Natural Gas Regulations for other low flashpoint fuels (FP<60 C), in particular; LPG Methanol Ethanol Hydrogen synthetic fuels will be developed later on. Storage: liquid or compressed All energy converters types: Low and high pressure internal combustion engines, gas turbines, boilers, fuel cells 5

6 IGF Code v/s IGC Code: some differences Segregation issues Location of fuel gas tanks Separation between high fire risks spaces and fuel storage / preparation spaces Use of Ro-ro spaces for fuel storage in mobile tanks Hazardous areas Dimensions and shape of the hazardous areas 6

7 IGF Code - Content The Draft Part A-1 of the IGF Code is addressing safety measures for natural gas fuelled ships as follows: Ship design and arrangement Fuel containments system Material and general pipe design Bunkering Fuel supply to consumers Power Generation [including propulsion and other energy converters] Fire safety Explosion protection Ventilation Electrical installations Control monitoring and safety systems 7

8 Bunkering operations Bunkering operations are not covered by IGF Code. Other standards are to be considered: ISO Guidelines for systems and installations for supply of LNG as fuel to ships (ISO/TS 18683) prepared by Technical Committee ISO/TC 67, BV guidelines on LNG bunkering (NI 618). 8

9 Tank arrangement for gas only installations Number of tanks IGF draft: For single fuel installations the fuel supply system shall be arranged with full redundancy and segregation all the way from the gas tanks to the consumer, so that a leakage in one system does not lead to loss of propulsion and/or power to essential consumers For single fuel installations (gas only), the fuel storage should be divided between two or more tanks. The tanks should be located in separate compartments. 9

10 Gas safe machinery spaces vs. ESD concept Arrangement of gas plant in machinery spaces : 2 possible solutions Gas safe machinery spaces : double walled piping system and monitoring of the primary barrier integrity. 4 arrangements possible: prevent gas leakage gas leakage occurs but is contained and detected: leakage towards inert gas leakage towards air leakage towards vacuum ESD protected machinery spaces: protected by means of gas detection and disconnection of all equipment that are not suitable for hazardous areas zone 1. This arrangement is permitted only when the pressure in the fuel supply system does not exceed 10 bar. 10

11 Location of LNG fuel tanks 11

12 Tank location - gas fuel tanks below accommodation Gas carriers: cargo area separated from accommodations Location of the tanks below accommodations is not precluded by the Interim Guidelines MSC.285(86). Tank location has been one of the most contentious and debated issue within the industry. Quite mandatory for some projects (e.g. passenger ships or ferries). According to Draft IGF Code, LNG fuel tanks can be located below accommodations provided that risks are properly identified and addressed. USCG Policy Letter Tanks must not be placed under accommodation, service or control spaces 12

13 Collision risk 13 13

14 Tank location distance from ship side Interim Guidelines : requirements similar to IGC Code Passenger ships: B/5 Other ships: 760 mm Are these requirements suitable for any type of gas fuelled ship? Question was asked to IMO Sub-Committee in charge of stability (SDC) SDC 1 outcomes : 2 possible approaches: Deterministic Probabilistic 14

15 Tank location Draft IGF Code 5.3 Shall be protected against mechanical damage. On open deck shall ensure sufficient natural ventilation. Shall be protected from external damage caused by collision or grounding with minimum distance of B/5 or 11.5 m. For passenger ships: B/10. Alternatively, following calculation method may be used to determine the acceptable location from shipside: fcn = fl x ft x fv Length shall not exceed [9][12]% of ship's length for passenger ships and [12][18]% for cargo ships.. Lowest boundary shall be located above the minimum distance of B/15 or 2.0 m. Shall be aft of transverse plane at 0.08L measured from forward perpendicular for passenger ships, and abaft of collision bulkhead for cargo ships. 15

16 Tank location Deterministic approach L L i l 16

17 Tank location Probabilistic approach f CN reflects the probability that the damage is not extending within the tank boundaries. L L i l Crashworthiness may also be recognized. IGF : For ships with a hull structure providing higher collision and/or grounding resistance, fuel tank location regulations may be specially considered in accordance with section 2.3 Alternative Design of this Code. 17

18 Experience from «Paul Kayser» LNG carrier grounding Grounding in June 1979 (Strait of Gibraltar) Severe damages of the double hull (speed: 19 knots) 18

19 Experience from «Paul Kayser» LNG carrier grounding Important deformations of the insulation, second barrier damaged Primary barrier remained tight 19

20 IGF Tank location different submissions Norway (SDC 1/24 and MSC 94/11/3): 1. Proposing probabilistic approach as an alternative to deterministic approach (SDC1/24). 2. Proposed tank length 9%Lfor deterministic approach and fcn = 0.01 for passenger ships and 12%L and fcn = 0.02 for cargo ships (SDC1/24) 3. Proposal for considering a longitudinal distance [0.3Ls] for non-overlapping fuel when calculating fcn (MSC 94/11/3) France (SDC1/24/5 and MSC 94/11/5): Supporting the probabilistic approach but with fcn = 0.02 for passenger ships; and fcn = 0.04 for cargo ships (SDC 1/24/5 and MSC 94/11/5) SDC 1 working group based on the proposals in SDC1/24 and SDC1/24/5 propose: The following two options should be decided on: 1. 9%L and fcn = 0.01 for passenger ships; 12%L and fcn = 0.02 for cargo ships; or 2. 12%L and fcn = 0.02 for passenger ships; 18%L and fcn = 0.04 for cargo ships. 20

21 IGF Tank location different submissions Bahamas, Canada and the United Kingdom (CCC 1/4/2): 1. It is proposed that the probabilistic calculation method is not included in the IGF Code and reference is made to the existing SOLAS provisions. 2. United Kingdom drew attention to existing provisions under SOLAS to allow LNG fuel tank location closer to the side of a ship by providing justification through Alternative Design & Arrangement (AD&A) provisions, as noted in section 2.3 of the draft IGF Code. Canada, the Marshall Islands and the US (MSC 94/11/7) 1.Do not agree to directly align the deterministic option with the probabilistic provisions 2.No provisions to limit the tank length when the tank is located inside the minimum offset from the side shell. Marshall Islands (MSC 94/11/17): 1.No provisions to limit the tank length when the tank is located inside the minimum offset from the side shell. 2.Probabilistic approach, produces results similar to the deterministic method. There is evidence that it produces an equivalent level of safety for fuel tank placement in larger gas fueled ships and its application should be limited to ships over 100 metres (Ls = 100 m). 3.Prefer the smaller values for Fcn 21

22 IGF Tank location different submissions Germany (MSC 94/11/18): 1.Outcome of validation calculations performed so far by different member states does not support the proposed draft provisions entirely. 2. There needs to be a discussion on whether the risk of a collision and its consequences should be looked at solely or possibly the combination of accidental situations and normal operation of the fuel tanks taking into account tank size and tank location in order to lead to a single criterion or multiple criteria to be included in the IGF Code. 3.Finalize the first version of the IGF Code containing the tank location criteria as per the Interim Guidelines 4.Further work on different kinds of gases and low-flashpoint fuels in order to widen the scope of the IGF Code; 5.Allow the relevant Sub-Committee to have an in depth appreciation of the proposed riskbased provisions for tank location. 22

23 LNG Bunkering

24 Bunkering LNG needs an hollistic approach 24

25 Availabilities in ECA and SECA zones 25

26 Existing and planned LNG bunkering facilities in North America LNG bunkering facilities planned in: Louisiana (Port Fourchon, 1 st bunkering facility in the US) Florida (Jacksonville) US Richmond, BC Canada Canada s West Coast and Quebec Other facilities proposed in Great Lakes, Gulf Coast, Pacific coast (Tacoma), In Port of Los Angeles, for trucks Several projects of LNG bunker barge or vessels in development 26

27 LNG Bunkering Situation in Europe Norway The NOx funds have supported for many years different types of LNG-fuelled ships, from coastal ferries to OSV and trans ocean tankers, as new buildings or conversion to LNG LNG as fuel is available at terminals (Stavanger, Flora, Bergen, Risavika), Numerous satellite stations / Since March 2014 LNG bunkering of 2 large ferries at Olso. Sweden LNG bunkering of Viking Grace by barge in Stockholm Brofjorden pilot project (BV is partner) New LNG bunkering terminal scheduled in Gävle (2015) Denmark LNG bunkering of Fjord Lines ferries Germany. In Hamburg, a 7.5 MW LNG Hybrid barge will deliver energy to a cruise ship as part of a joint project with AIDA Cruises. 27

28 LNG Bunkering Situation in Europe Netherlands Up to now only inland shipping could bunker LNG. But Rotterdam is offering the possibility to bunker LNG as fuel for ocean going ships based on a specific and case by case approach. Belgium In Zeebrugge, LNG bunkering by barge will be possible by the end of GDF SUEZ, Mitsubishi and NYK will develop the LNG bunkering market through an LNG bunkering vessel to be built by Hanjin Heavy Industries. LNG bunker by truck is practised on case by case. Antwerp Port Authority is continuing its focus on LNG with the aim of setting up a permanent bunkering station at the port by the beginning of Truck-to-ship bunkering is already possible at the port a truck collects LNG from the import terminal in Zeebrugge which is then delivered to the barges on the quayside. 28

29 LNG Bunkering Situation in France DUNKERQUE LNG, Air Liquide and Exmar make up the consortium that presented its successful project during a Call for Expressions of Interest (CEI). * As part of the project, Dunkerque LNG and Air Liquide will be responsible for the preliminary studies, the engineering and investments. Exmar will handle the preliminary studies, the engineering and the building of a bunkering vessel, the capacity of which is yet to be defined according to LNG requirements. NANTES SAINT NAZAIRE Elengy is bringing on stream the liquefied natural gas (LNG) road tanker loading station at the Montoir de Bretagne LNG terminal.. It thereby enables its energy supplier customers to come and load road tankers with LNG, for onward transportation to the point of use. The product then serves to supply industrial users or outlets for the distribution of LNG fuel for vehicles or vessels. 29

30 Inland Navigation Cooperation Agreement in Europe: between the ports of Antwerp, Mannheim, Rotterdam, Strasbourg and Switzerland for the distribution of LNG in the European network of inland navigation along the entire Rhine - Main Danube network. European Union has allocated 40 million to support this project. 30

31 LNG bunkering procedures

32 Existing IMO Regulation on LNG bunkering IGF Code : entering into force in 2016 / 2017 IGF Code Ship design Risk evaluation (chapter 4) Bunkering station: functional requirements and design, flexible manifold (Chapter 8) Ventilation of the bunkering station (chapter 13) Control systems, monitoring and safety of bunkering (chapter15) Operations (chapter18) Responsabilities, Tests to realise before starting bunkering operations Communications between bunkering facilities and receiving ship Acces to the different spaces that could contain gas Inerting and venting of bunkering installations 32

33 ISO Technical Specifications ISO / DTS Guidelines for systems and installations for supply of LNG as fuel to ships Ensuring the safety of personnel (crew, fueling operators, third party involved) Minimize / eliminate emissions of natural gas in the atmosphere Promote the standardization of equipment (connectors and instrumentation) and procedures Provide functional requirements based on principles (which will allow for improvements and further developments) and not prescriptive requirements based on existing solutions and limited experience 33

34 Initiatives from ESSF (EMSA), SGMF and IAPH The ESSF (EMSA) has the following objectives : Develop consistent rules with international regulations Filling the regulatory gaps and identify areas where it is necessary to go beyond SGMF (SIGTTO) is commited to produce guidelines for LNG bunkering to the industry Maintain the excellent level of safety in current LNG transport industry IAPH finalizes checklists for LNG bunkering vessels covering different refueling scenarios: By bunker vessel By fixed installation ashore By truck 34

35 Initiatives from IACS In July 2014, IACS decided to launch a Project Team on development of Unified LNG Bunkering Guidelines with the following objectives : Elaborate a set of guidelines for ensuring the safety of LNG bunkering operations. Help to develop the LNG bunkering process by providing an unified regulatory framework in a tentative for clarity and homogeneous level of safety Consider a voluntary submission to IMO in view of adoption by the Industry. The objective is to deliver comprehensive technical safety guidelines (based on existing documentation) - To be comprehensive and technically consistent in view of a large adoption by the Industry. - Feed back from recent LNG bunkering incident is taken into account. - in liaison with stake holders forum and professional associations (SGMF, IAPH, ESSF). - Focus first on safety, not really on commercial aspects such as quality of LNG except when safety may be undirectly impacted. - Training will be discussed. 35

36 BV Guidelines on LNG bunkering (NI 618) Objective : To provide a framework for the development of the various procedures to be implemented to ensure safe operation of LNG bunkering The Guidelines cover the following points: 1. Safety aspects of LNG bunkering 2. Typical descriptions of LNG bunkering station, receiving vessel and LNG fueling facility 3. General framework to be put in place before starting a project of LNG bunkering of a ship 4. Compatibility between the receiving vessel and the LNG fueling facility 5. Guidelines for the development of a procedure for LNG bunkering 6. Guidelines for the safety assessment of the LNG bunkering 7. Guidelines for the development of a management plan for emergency situations 36

37 Setting up a ship bunkering project The key actions to be performed before setting up a ship bunkering project include: Ensure that the receiving ship and the bunkering facility are compatible Develop the LNG bunkering procedure for the concerned ship and bunkering facility Perform the Safety assessment and HAZOP Develop a Management Plan for emergency situations in connexion with the Safety assessment Set up the organization in charge of the bunkering operations and provide adequate information, instructions and supervision to the persons involved in the LNG bunkering operations Establish a training program 37
