2 Page 2 INTERNATIONAL ASSOCIATION OF CLASSIFICATION SOCIETIES (IACS) COMMUNITY OF EUROPEAN SHIPYARDS' ASSOCIATIONS (CESA) SOCIETY OF INTERNATIONAL GAS TANKER AND TERMINAL OPERATORS LIMITED (SIGTTO) INTERFERRY INTERNATIONAL TRANSPORT WORKERS FEDERATION (ITF) Terms of reference for the working group 3 Based on the correspondence group's report (CCC 1/4), taking into account documents CCC 1/4/1, CCC 1/4/3, CCC 1/4/5, CCC 1/4/6, CCC 1/4/8, CCC 1/4/9, CCC 1/4/10, CCC 1/4/12, CCC 1/4/13, MSC 93/21/3, CCC 1/INF.18, CCC 1/INF.24 and CCC 1/INF.25 1 as well as the outcomes of SDC 1, HTW 1, SSE 1 and MSC 93 (CCC 1/2 and CCC 1/2/1) and the comments and decisions made in plenary, the working group was instructed to:.1 finalize the draft International Code of Safety for Ships using Gases or other Low-flashpoint Fuels (IGF Code), focusing on remaining parts identified in document CCC 1/4 (paragraph 8 and annex 2);.2 finalize the draft SOLAS amendments to make the Code mandatory, taking into account MSC.1/Circ.1483;.3 develop a work plan for the next phase in the development of the IGF Code;.4 decide whether the correspondence group should be re-established for facilitating the next phase in the development of the IGF Code and, if so, prepare terms of reference for consideration by the Sub-Committee; and.5 submit a written report by Thursday, 11 September SOLAS amendments on the application of the IGF Code 4 The group decided to start its work with developing the draft amendments to SOLAS in order to make the IGF Code mandatory. It was agreed to use the text of amendments prepared by the correspondence group, as set out in annex 3 to document CCC 1/4, and further editorially amended by the Secretariat as a base document for discussion. Definition of low-flashpoint fuel 5 As instructed, the group discussed the issue of definition of the term "low-flashpoint fuel" for inclusion in SOLAS regulation II-1/2. It was agreed that the definition should be a generic definition capturing possible future fuels and that the detailed requirements related to the various fuels should be set out in SOLAS chapter II-2 and the IGF Code. It was also agreed that rather than defining a fixed temperature, reference should be made to temperatures below the limit defined in SOLAS chapter II-2. 1 Documents CCC 1/INF.24 and CCC 1/INF.25 were referred to the working group for information only.

3 Page 3 Alternative design and arrangements 6 In discussing the draft amendments to part F of SOLAS chapter II-1, the group agreed to the editorial amendments proposed by the Secretariat. The group also agreed to insert reference to MSC.1/Circ.1455 in the footnote to paragraph 3 of SOLAS regulation II-1/55. New part G of SOLAS chapter II-1 7 The group further modified the draft paragraph 1 of SOLAS regulation II-1/56 on application, taking into account the decisions made in plenary. 8 Regarding paragraph 2 of the draft SOLAS regulation II-1/56, it was noted that such a requirement is already contained in paragraph 3 of SOLAS regulation II-1/1 and need not be repeated in part G. Consequently, the group agreed to delete paragraph 2 and renumbered the remaining paragraph accordingly. 9 The group made some editorial modification to the draft SOLAS regulation II-1/56 in order to capture ships that could make use of, for example, low-flashpoint oil without going through a conversion. The group also discussed the possible vague expression on "the date on which such a conversion commenced". In particular, it was proposed to use the date when a ship is "placed into service"; however, after a lengthy discussion, it was agreed to keep the term proposed by the correspondence group as already used in the Convention. During the discussion, concerns were raised that the proposed wording would not capture a situation where changes of fuel and/or machinery arrangements were made for a ship already using low-flashpoint fuel and that there could be a lack of harmonization in application to existing ships. However, the group agreed that it was difficult to foresee all possible alterations and that this is sufficiently covered by paragraph 3 of SOLAS regulation II-1/1. 10 The group agreed, in general, to the proposal by the delegation of Japan to include a separate paragraph under application dealing with ships using their cargoes as fuel and complying with chapter 16 of the IGC Code. The agreed text was included as paragraph 3 in the draft SOLAS regulation II-1/56. Amendments to SOLAS regulation II-2/4 11 In discussing the amendments to SOLAS regulation II-2/4, the group further amended the headings in existing section 2 and agreed that it was outside its terms of reference to amend the existing paragraphs and dealing with flashpoint of not less than 43 0 C. 12 The group further agreed to use the first alternative proposed by the correspondence group for paragraph of SOLAS regulation II-2/4 as a basis for discussion and finalized the amended text. It was unanimously agreed that as the amended paragraph refers back to part G, the grandfathering was covered. 13 In discussing the amendments to SOLAS chapters II-1 and II-2, the group noted that the general application dates for these chapters are 1 January 2009 and 1 July 2012, respectively. However, the intention was that part G of SOLAS chapter II-1 should also apply to ships built prior to those dates. In view of the above, the Secretariat was instructed to develop the necessary text for the ships built prior to the general application dates for inclusion in the draft SOLAS amendments.

4 Page 4 Amendments to the forms of certificates 14 The group had a lengthy discussion on the proposed amendments to the forms of SOLAS certificates. Subsequently, the group, having agreed that the SOLAS certificates are very generic certificates stating that the ship complies with SOLAS without going into a number of details, agreed to a general paragraph to be introduced in the forms of SOLAS certificates. As instructed, three separate sets of amendments were developed by the group to the forms of certificates for SOLAS 1974, the Protocol of 1978 and the Protocol of 1988, accordingly. 15 In this context, the delegation of the Marshall Islands suggested that the supplement to the IAPP Certificate under MARPOL Annex VI may also be used for providing additional information. Having discussed the proposal by the Marshall Islands, the group agreed to invite the Sub-Committee to request MEPC to consider what actions, if any, are needed for low-flashpoint fuels with respect to MARPOL Annex VI certification. 16 With regard to the proposal by the delegation of Japan to develop a separate IGF Code certificate, the group recalled that the proposal was initially meant for cargo ships of less than 500 gross tonnage, and the correspondence group had agreed that a separate certificate was not required as they had proposed to amend the forms of SOLAS certificates. Final text of draft SOLAS amendments 17 Having considered the above issues, the group agreed to the draft amendments to SOLAS to make the IGF Code mandatory, as set out in annex 1, for consideration by the Sub-Committee with a view to submission to MSC 94 for approval and subsequent adoption, together with the draft IGF Code. Development of the International Code of Safety for Ships using Gases or other Low-flashpoint Fuels (IGF Code) 18 As instructed, the group reviewed the draft IGF Code prepared by the correspondence group, as set out in annex 1 to document CCC 1/4, and further editorially revised by the Secretariat, with a view to finalizing it for submission to MSC 94 for approval and subsequent adoption. Specific requirements for ships using natural gas as fuel 19 The group agreed to start the review of the draft IGF Code with finalizing the specific requirements for ships using natural gas as fuel, contained in part A-1. With regard to the draft regulations for fuel cells, as set out in section 10.6 of the draft Code, the group agreed to consider them later in the week, if time permits. 20 The draft text of part A-1 of the IGF Code was finalized according to the list of remaining issues set out in annex 2 of document CCC 1/4, related documents submitted to CCC 1 under agenda item 4 and decisions made in plenary. 21 The group discussed paragraphs and of the draft Code, in particular the routing of fuel pipes through the spaces defined as accommodation spaces in SOLAS chapter II-2. After a lengthy discussion, it was agreed that fuel pipes could be routed through areas of the ship containing general accommodation spaces, given the safety provisions in the Code, but not through the individual accommodation spaces themselves. Finally the group agreed that it was sufficient to retain the requirements in the ship design and arrangement section, therefore, paragraph was deleted.

5 Page 5 22 Regarding paragraphs and of the Code the group agreed to reinstate the sentence "For type C tanks, the hold space may be considered as a cofferdam". The group also agreed that it was sufficient to have the requirements in the fire protection section and consequently paragraph was deleted. 23 With regard to the new paragraph proposed by Japan (CCC 1/4/9), the group recalled that this has been discussed before and resulted in the inclusion of paragraph and decided that the proposed requirements on rollover need not be included in the Code. The group recognized the concerns raised by Japan, and recommended that in the application of section 4.2 of the Code, the Guidelines for prevention of rollover in LNG ships, SIGTTO, 2012 should be considered. The group also noted that there is a possibility to propose amendments to the Code in future. 24 Regarding the proposal by the delegation of Norway (CCC 1/4/6) to include the formulae for acceleration components in the IGF Code, the group decided to refer paragraph of the IGC Code in the footnote to paragraph The group, having seen merits in the proposals to amend paragraph (further renumbered as ), recalled that the regulations for fire protection in section 11.3 of the draft IGF Code were developed by the Sub-Committee on Fire Protection (FP). In view of the above, the group, recognizing that proposal of any amendments to this section may defer the adoption of the IGF Code, agreed to keep the text developed by the FP Sub-Committee. 26 In this context the observer from IACS raised the issue that the monitoring and alarm actions for "Fire detection in fuel storage hold space" in table 1 of chapter 15 should be amended to also include "tank connection spaces". Ultimately table 1 was amended to include "the ventilation trunk for fuel containment system below deck" to be consistent with the text of the requirements under of the IGF Code. The meaning of "the ventilation trunk for fuel containment system below deck" and the alarm and shutdown requirements as now reflected in the IGF Code was unclear to IACS. It was IACS understanding that a fire detection and alarm system is to be provided for fuel storage hold spaces and tank connection spaces. 27 The group made a number of amendments to table 1 of chapter 15 in order to make it consistent with the regulations in the draft IGF Code. Part A General 28 The group considered the remaining issues in part A and made a number of amendments in particular to the definitions in section In discussing section 2.1 the group, having considered pros and cons related to copying the draft text of new SOLAS regulation II-1/56 into the IGF Code, agreed to keep the reference to part G of SOLAS chapter II-1 only, acknowledging that this part of the IGF Code may be amended in future to include regulations for other fuels. 30 With regard to the issue of tank location, the group noted that SDC 1 had introduced a definition of breadth (B) that was different from the one in paragraph (further renumbered as 2.2.2) of the draft IGF Code and the revised IGC Code. For the sake of consistency in the draft IGF Code, the group agreed to use the definition introduced by SDC The group had a lengthy discussion on the definition of control station in paragraph Different from SOLAS, an engine control room has been proposed for inclusion in the definition of the draft IGF Code. Subsequently, it was agreed to include an

6 Page 6 engine control room in the definition, with the understanding that this definition would apply for the requirements of the IGF Code only, and would not affect any of the SOLAS requirements for control station. The delegation of Spain was of the view that an engine room control room installed in the engine room should be considered a control station with regards to SOLAS requirements. 32 The group did not have time to discuss the prescriptive requirements for fuel cells and, therefore, recommended forwarding the fuel cells section to the correspondence group, if established, with a view to reintroduction in the IGF Code. In view of the above, section 10.6 was deleted from the draft IGF Code. In this regard, the delegations of Germany and CESA reiterated the need to finalize the regulation on fuel cells as soon as possible. Final text of draft IGF Code 33 Having considered the above matters, the group agreed to the draft IGF Code, as set out in annex 2, for consideration by the Sub-Committee with a view to submission to MSC 94 for approval and subsequent adoption. Interpretation for obtaining the required distance at the turn of the bilge 34 The group considered document MSC 93/21/3 (France), proposing an interpretation for obtaining the required distance at the turn of the bilge for passenger ships. The group was of the opinion that the proposed interpretation is directly related to tank location and should, therefore, be discussed at MSC 94 together with other submissions on this issue. The group noted that different from the IGC Code, the IGF Code does not contain any guidance or interpretations. In view of the above, the group recommended that this document be forwarded to MSC 94 for consideration together with other documents on tank location. Minor editorial corrections 35 The group agreed to invite the Sub-Committee to authorize the Secretariat, when preparing the final text of the IGF Code and SOLAS amendments, to effect any editorial corrections that may be identified, as appropriate, including updating references to renumbered paragraphs, and to bring to the attention of the Committee any errors or omissions which would require further action. Development of a work plan for the next phase in the development of the IGF Code 36 As instructed, the group discussed the further actions that may need to be included in a work plan for the next phase of development of the IGF Code such as the need to consider future proposals for the use of additional fuels for inclusion in the IGF Code. The work plan agreed by the group is set out in annex 3 for consideration by the Sub-Committee. Re-establishment of the correspondence group 37 Taking into account the progress made at this session, the group recommended that the IGF Correspondence Group be re-established, under the coordination of Sweden, 2 and instructed, based on the work plan for the next phase of development of the IGF Code, to: 2 Coordinator: Mr. Saeed Mohebbi Civil Aviation and Maritime Department Olai Kyrkogata 35, SE Norrkoping, Sweden Tel: saeed.mohebbi@transportstyrelsen.se

7 Page 7.1 using annex 4 to document CCC 1/4 as a basis, further develop guidelines for ships using ethyl or methyl alcohol as fuel;.2 using section 10.6 of annex 2 to document CCC 1/4 as a basis, further develop measures for fuel cells for inclusion in the IGF Code as and when appropriate;.3 using annex to CCC 1/4/12 as a basis, further develop measures for ships using low-flashpoint diesel oil for inclusion in the IGF Code as and when appropriate; and.4 submit a report to CCC In relation to the terms of reference for the IGF Correspondence Group, the delegation of the United States informed the group that they, together with Canada, have submitted document MSC 94/18/5, proposing that the Committee consider at its ninety-fourth session the acceptance of oil fuels with a minimum flashpoint of 52 C, without additional requirements for analysis or supplemental safety equipment. Based on an analysis of hazards and existing protective measures, this paper concludes that the use of 52 C oil fuels is not expected to have a significant impact on fire safety, but will permit a broader range of common transportation fuels to be used in the maritime sector. The United States noted that neither the Sub-Committee nor the IGF Working Group had a substantive discussion on this issue, but instead agreed to add a terms of reference to the agenda while recognizing that MSC 94 would be discussing this issue in response to document MSC 94/18/5. Application of the Interim Guidance on drafting of amendments to the 1974 SOLAS Convention and related mandatory instruments (MSC.1/Circ.1483) 39 As instructed, the group prepared, on a trial basis, the check/monitoring sheet and records in accordance with the Interim Guidance (MSC.1/Circ.1483) for submission to MSC 94 together with the draft amendments to SOLAS and draft IGF Code. The completed check/monitoring sheet and records are set out in annex 4. Action requested of the Sub-Committee 40 The Sub-Committee is invited to approve the report in general and, in particular, to:.1 endorse the group's request to the Secretariat to develop the necessary text for the ships built prior to the general application dates for inclusion in the draft SOLAS amendments (paragraph 13);.2 note the group's decision on the suggestion to use the supplement to the IAPP Certificate under MARPOL Annex VI for providing additional information for ships using low-flashpoint fuels and instruct the Secretariat to advise MEPC 68 on the need to consider what actions, if any, are needed for low-flashpoint fuels with respect to MARPOL Annex VI certification (paragraph 15);.3 agree to the draft amendments to SOLAS in order to make the IGF Code mandatory, for submission to MSC 94 for approval and subsequent adoption (paragraph 17 and annex 1);

22 Annex 2, page 8 1 Preamble The purpose of this Code is to provide an international standard for ships using low-flashpoint fuel, other than vessels covered by the IGC Code. The basic philosophy of this Code is to provide mandatory provisions for the arrangement, installation, control and monitoring of machinery, equipment and systems using low-flashpoint fuel to minimize the risk to the ship, its crew and the environment, having regard to the nature of the fuels involved. Throughout the development of this Code it was recognized that it must be based upon sound naval architectural and engineering principles and the best understanding available of current operational experience, field data and research and development. Due to the rapidly evolving new fuels technology, the Organization will periodically review this Code, taking into account both experience and technical developments. This Code addresses all areas that need special consideration for the usage of the low-flashpoint fuel. The basic philosophy of the IGF Code considers the goal based approach (MSC.1/Circ.1394). Therefore, goals and functional requirements were specified for each section forming the basis for the design, construction and operation. The current version of this Code includes regulations to meet the functional requirements for natural gas fuel. Regulations for other low-flashpoint fuels will be added to this Code as, and when, they are developed by the Organization.

24 Annex 2, page ESD means emergency shutdown Explosion means a deflagration event of uncontrolled combustion Explosion pressure relief means measures provided to prevent the explosion pressure in a container or an enclosed space exceeding the maximum overpressure the container or space is designed for, by releasing the overpressure through designated openings Fuel containment system is the arrangement for the storage of fuel including tank connections. It includes where fitted, a primary and secondary barrier, associated insulation and any intervening spaces, and adjacent structure if necessary for the support of these elements. If the secondary barrier is part of the hull structure it may be a boundary of the fuel storage hold space. The spaces around the fuel tank are defined as follows:.1 Fuel storage hold space is the space enclosed by the ship's structure in which a fuel containment system is situated. If tank connections are located in the fuel storage hold space, it will also be a tank connection space;.2 Interbarrier space is the space between a primary and a secondary barrier, whether or not completely or partially occupied by insulation or other material; and.3 Tank connection space is a space surrounding all tank connections and tank valves that is required for tanks with such connections in enclosed spaces Fuel preparation room means any space containing pumps, compressors and/or vaporizers for fuel preparation purposes Gas means a fluid having a vapour pressure exceeding 2.8 bar absolute at a temperature of 37.8 C Gas consumer means any unit within the vessel using gas as a fuel Gas only engine means an engine capable of operating on gas-only, and not able to switch over to operation on any other type of fuel Hazardous area means an area in which an explosive gas atmosphere or a flammable gas or vapour is or may be expected to be present, in quantities such as to require special precautions for the construction, installation and use of electrical apparatus or any other equipment that may provide potential sources of ignition High pressure means a maximum working pressure greater than 10 bar Independent tanks are self-supporting, do not form part of the ship's hull and are not essential to the hull strength LEL means the lower explosive limit.
