1 Working together for a safer world IMO Ships Systems & Equipment (SSE 1) Summary Report Introduction The 1st session of the IMO Sub-Committee on Ship Systems and Equipment (SSE 1) was held from 10-14, at the IMO headquarters in London. This briefing summarises subjects discussed that are relevant to the work of Lloyd's Register. It should be noted that the SSE Sub-Committee was created from elements of the previous Design and Equipment (DE), Fire Protection (FP) and Stability, Load line and Fishing Vessels (SLF) sub-committees. Summary of discussions The following agenda items are relevant to the work of Lloyds Register: Decision of other IMO Bodies (agenda item 2) SSE 1 considered the outcomes of the Marine Environment Protection Committee (MEPC) 65, Marine Safety Committee (MSC) 92, Standards for Training and Watchkeeping (STW) Sub-Committee 44, Navigation (NAV) Sub- Committee 59, Dangerous Goods, Solid cargoes and Containers Sub-Committee (DSC) 18, Council 110, Assembly 28 and Ship Design and Construction Sub-Committee (SDC), most notably: Amendment to the MARPOL Annex I regulation 12 (Agenda item 20) Requirements for periodic servicing and maintenance of lifeboats and rescue boats (Agenda item 12) Development of amendments to the IMDG Code and supplements Outcome of discussions on the polar code at SDC 1 (see also Agenda item 20) These items will be covered under the relevant Agenda items. Development of requirements for ships carrying hydrogen and compressed natural gas vehicles (agenda item 3) SSE 1 discussed the draft MSC circular Recommendation on safety measures for existing pure car carriers transporting motor vehicles with compressed hydrogen or natural gas in their tanks for their own propulsion. This circular has been developed in support of the draft amendments to SOLAS regulations II-2/1, II-2/3 and II-2/20-1, which were approved by MSC 92 with a view for adoption at MSC 93. One delegation supported by others raised the concern that it is not practical for the ship operator to check all the vehicles but that it should be the responsibility of the shipper. SSE 1 agreed that the inspection and leak testing of vehicles is the responsibility of the shippers. Reference was made to SOLAS Chapter II-2 regulation 20-1 in its entirety. It will be up to the flag administration to consider which parts of the regulation apply, however it is expected most administrations will only mandate the retrospective parts of the regulation. Development of amendments to SOLAS regulation II-1/40.2 concerning general requirements on electrical installations (agenda item 4) The proposals submitted to the DE Sub-Committee to address the issue of electrical equipment being built to a standard were generally supported; however, they were unable to agree on the correct terminology of such a proposal Lloyd s Register Briefing Note SSE 1 Summary Report 1

2 2 in order to amend SOLAS. It has also been noted that this proposal may be better addressed by a method other than amendments to SOLAS. There was no support for the proposal to amend SOLAS and it was agreed that this issue is already covered sufficiently by SOLAS, ISM and Class Rules. MSC 93 will be informed that work on this issue is now completed. Smoke control and ventilation (agenda item 5) The issue of smoke control and ventilation has been extensively discussed previously by the FP Sub-Committee, however the matter is still pending. SSE 1 considered submissions on smoke management systems (SSE 1/5, SSE 1/5/1) at this session but no conclusions were determined. SSE 1 finalised functional requirements for a smoke control system. The functional requirements aim to give a framework for a smoke management system while maintaining the prescriptive requirements of SOLAS. A correspondence group was formed to continue this work and to outline performance criteria. Proposed future actions on this item were agreed by the working group including; Prepare proposed amendments to SOLAS Chapter II-2. Consider the suitability of detailed performance criteria that may be adapted from existing sources/standards Further develop the draft performance standard for the assessment of smoke control system Work on this item is ongoing and will continue at SSE 2. Development of amendments to SOLAS regulation II-2/20 and associated guidance on air quality management for ventilation of closed vehicle places, closed ro-ro and special category spaces (agenda item 6) Amendments to SOLAS regulations II-2/ and II-2/ are proposed to introduce air quality management for the ventilation of closed vehicle spaces, closed ro-ro and special category spaces together with proposed draft amendments to design guidelines and operational recommendations for ventilation systems in ro-ro cargo spaces (MSC/Circ.729). SSE 1 considered the recommendations in the Report of the Correspondence Group and concluded: Agreed amendments to SOLAS Chapter II-2 allowing the optional use of an air quality management system in lieu of prescriptive requirements for ventilation of ro-ro and special category spaces. The group also agreed that the amendments to SOLAS should apply to all vessels (both existing and new build). Modifications to the draft guidelines for MSC Circ.729 (design guidelines and operational recommendations for ventilation in ro-ro spaces). Development of life safety performance criteria for alternative design and arrangements for fire safety (MSC/Circ.1002) (agenda item 7) SSE 1 considered proposals to revise MSC/Circ.1002 (Guidelines on Alternative Design and Arrangements for Fire Safety. After a brief discussion it was decided to take this work forward by Correspondence Group to report at SSE 2. Development of a new framework of requirements for safety objectives and functional requirements for the approval of alternative design and arrangements for SOLAS chapter II-1 (parts C, D and E) and III (agenda item 8) SSE 1 continued the work on the development of safety objectives and functional requirements for the approval of alternative design and arrangements for SOLAS chapters II-1 and III, continuing the work of the DE Sub-Committee. The following was considered: Investigation of SOLAS chapter III requirements based on draft goal-based guidelines (SSE 1/8), including; Gap analysis referencing the amendments to SOLAS chapter III and to the LSA Code as well as related guidelines for the evaluation of existing on-load release and retrieval systems (MSC.1/Circ.1392), (SSE 1/8/1) SSE 1 discussed that the circular is, in some cases, not being implemented as intended and that the information contained in the GISIS database regarding the evaluation of hooks under the requirements of MSC.1/Circ.1392, only provides a limited use because frequently the information provided advises that a particular hook has been found to be compliant after modification without also including details of the modification. Following extensive discussion it was decide that SSE is not in the position to amend the structure of and the contents of the GISIS Module on Evaluation of Hooks and decided to take no further action.

3 3 Goal-based standards safety-level approach Exercise (SSE 1/8/2, SSE 1/INF.5) SSE 1 agreed that: MSC.1/Circ.1455 on guidelines for the approval of alternatives and equivalents as provided for in various IMO instruments should be used for the purpose of approval of alternative design and arrangements for SOLAS chapters II-1(Parts C, D, and E) and III. for the purpose of paragraph of that MSC circular, the framework requirement in SOLAS chapters II-1 (Parts C, D, and E) and III should be developed. updated the work plans for the new framework of requirements for life-saving appliances and for the draft safety objectives and functional requirements of the guidelines on alternative design and arrangements for SOLAS chapter II-1 and chapter III. recommended that a correspondence group on life-saving appliances be established to continue the work intersessionally. The correspondence group will also be asked to consider the scope of application and drafting amendments to the LSA Code (DE57/23/5) (See Agenda item 20) any amendments to SOLAS Chapter III and LSA Code are planned to enter into force in Guidelines on alternative design and arrangements for SOLAS Chapter II-1 and III are planned to be approved at MSC 96. SSE 1 also considered a proposal to make the provisions of MSC.1/Circ.1206/Rev.1 mandatory (SSE 1/8/3). SSE 1 offered no support for this issue. However, the concerns of at least one delegation were noted and the views will be brought to the attention of MSC 93. Development of amendments to the LSA Code for thermal performance of immersion suits (agenda item 9) The development of amendments to the LSA Code for thermal performance of immersion suits was considered under this agenda item. SSE 1 continued the work of the DE Sub-Committee based on the report of the Correspondence Group which due to lack of time at DE 57 was deferred to DE 58 now SSE. The target completion date for this agenda item was 2014 however, after some discussion Member States supported the proposal that further discussion should be postponed and the issue should be removed from the active agenda pending the completion of ongoing practical work by Member States. Development of amendments to the LSA Code for free-fall lifeboats with float-free capability (agenda item 10) SSE 1 reviewed a paper from DE 57 submitted by the International Life-saving Appliance Manufacturers Association (ILAMA) which provided a summary of the status of the development of new requirements and guidelines for free-fall lifeboats with float free capabilities and which concluded that the technical challenges involved in developing such a lifeboat would compromise safety requirements. Although one Member State offered to provide papers for discussion at SSE 2 it was agreed that this issue should be removed from the work programme of SSE and the associated draft amendment to SOLAS Chapter 12 deleted. Development of amendments to the 2009 MODU Code concerning lifeboat drills (agenda item 11) SSE 1 discussed amendments to paragraph of the 2009 MODU Code referring to the requirements in SOLAS regulation III/ , with a view to allowing an alternative procedure for lifeboat tests exclusively for Mobile Offshore Units in operational areas. The outcome of the discussions concluded with: A drafted amendment to paragraph of the 2009 MODU Code for adoption by MSC Practice musters and drills In paragraph a new sub-paragraph ".3" is added with the following: ".3 alternatively, the provisions regarding launching and manoeuvring may be considered as having been met for those units that have, (a) implemented the Guidelines developed by the Organization and they are included in the unit's operating procedures or, (b) by other equivalent means acceptable to the Administration." developed draft Guidelines on alternative methods for lifeboat drills on MODUs for approval by MSC 94. The group also noted that the draft guidelines may be used in conjunction with the provision of on-board training and instructions in paragraph of the 1979 MODU Code and in paragraph of 1989 MODU code.

4 4 Revision of the Recommendation on conditions for approval of servicing stations for inflatable liferafts (resolution A.761 (18)) (agenda item 12) SSE 1 considered the development of amendments to Resolution A.761 (18) and the amendments to Guidelines under MSC.1/Circ.1328 concerning the expiry date of items in the contents of packaged inflatable liferafts. The majority supported the amendment to Resolution A.761 (18) paragraph 5.11 to read Items of equipment should be checked to ensure that all are in good condition and dated items should be replaced in cases where the expiry date falls before the next service date of the liferaft for adoption by MSC 94. Development of requirements for onboard lifting appliances and winches (agenda item 13) Over the last 10 years there have been a number of accidents (107) involving onboard lifting appliances, some of which have resulted in fatalities. Recognising that this is unacceptable the IMO has been looking at ways to improve the situation. A correspondence group reported that it has identified that the root cause of the majority of accidents is lack of maintenance or poor/incorrect operation. SSE 1 decided that there should be a further period for collection and analysis of additional data and corroborative evidence before any decision could be taken on whether there is a need to take any measures. The scope, extent and application of any measures (whether this should be mandatory through amendments to SOLAS or non-mandatory guidance) could then be considered and agreed by SSE. The Correspondence Group, under the co-ordination of New Zealand will be reformed to undertake this work. All Member States and international organisations are encouraged to seek further incident data and make it available to the Correspondence Group. The Correspondence Group will make recommendations with regard to types of equipment, types of ships, focus of the measures and applicability to existing and/or new ships. The scope of any measures (a) will not be limited to cargo handling appliances, i.e. stores cranes, engine room cranes, A- frames, hose handling cranes etc. may also be included; however, elevators, escalators and LSA equipment will be excluded, except for LSA equipment having a dual purpose which qualifies it for inclusion (b) will apply to all types of ship essentially covered by SOLAS (c) may apply to both new and existing ships. LSA s on MODUs should not be included in the scope of application. The collection and analysis of additional incident data will be reviewed and analysed and a framework for potential measures shall be proposed by the correspondence group. A draft shall be submitted to Sub-Committee by 2017 for approval. Consideration related to the double sheathed low-pressure fuel pipes for fuel injection systems in engines on crude oil tankers (agenda item 14) MEPC requested that SSE 1 consider how to proceed with regard to Risk Control Option (RCO) 9 (MEPC 58/17/2 & MEPC 58/INF 2) (double sheathed low-pressure fuel pipes for fuel injection systems in engines) of the Formal Safety Assessment (FSA) study on crude oil tankers, for application to new ships only. SSE 1 was asked to submit concrete proposals and comments on the way forward for this issue to SSE 2 restricting the scope to new build crude oil tankers. Development of amendments to the provisions of SOLAS chapter II-2 relating to the secondary means of venting cargo tanks (agenda item 15) Proposed amendments to SOLAS regulations II-2/4.5, II-2/11.6.1, II-2/11.6.2, and II-2/ were considered to clarify the provisions relating to the secondary means of venting cargo tanks. In general terms, the proposal will require new tankers to install full flow P/V valves on each cargo tank in order to ensure adequate safety against over-and-under pressure in the event a cargo tank isolation valve is damaged or inadvertently closed. After a brief discussion SSE 1 agreed to the draft amendment to SOLAS for approval by MSC 94 and subsequent adoption. Development of amendments for the requirements for foam type fire-extinguishers in SOLAS regulation II- 2/10.5 (agenda item 16)

5 5 A proposed amendment to SOLAS regulation II-2/ was discussed with SSE 1 divided. While some delegations supported the proposal to reduce the requirement for foam type fire extinguishers in the described circumstances, others were concerned that experience had proved that the additional protection should not be compromised. As no consensus could be reached any decision on this issue was postponed with a view to requesting MSC for an extension to the deadline for the output and for Member States to submit papers with their comment s to SSE 2. Consideration of IACS unified requirements (agenda item 17) While this agenda item is set for interpretation ; amendments to the MARPOL Annex I, regulation 12 were discussed with a view to formalising the interpretation given in MEPC.1/Circ.753 and MEPC.1/Circ.753/rev.1 (see below). In addition, the following IACS Unified Interpretations were submitted for approval: Sample Extraction Smoke Detection System (IACS UI SC260) (SSE 1/17/2) It was agreed that providing an indicating unit is available on the navigation bridge then the control panel for a sample smoke extraction system could be placed in the CO 2 room. Fixed fire detection and fire alarm systems (FSS Code, chapter 9) (IACS UI SC 35) (SSE 1/17/3) This was fully supported and a draft MSC circular was prepared for submission to MSC 94 Testing and approval of pipe penetrations and cable transits, which do not utilize conventional components, for use in A class divisions (part 3 of annex 1 to the 2010 FTP Code (IACS UI FTP 6) (SSE 1/17/4) Clarification and guidance for the laboratory testing of penetrations was agreed to prohibit loose materials from being used in pipe and cable penetrations. The use of the 6mm gap gauge as defined in the FTP Code Annex 1 Part 3 was also confirmed as a suitable method to ensure no visible openings are present in the penetration at the start of the test. Ventilation ducts (SOLAS regulation II-2/9.7) (IACS UI SC99) SSE1/17/5 It was agreed that a short length not exceeding 600mm of flexible bellows constructed of combustible material may be used for connecting fans to the ducting in the air conditioning room. As the amendment to the regulation is not yet adopted SSE will recommend to MSC that they consider a modification to the draft amendment. The UI will still be necessary for those ships to which the existing text applies. Gaskets used in fixed gas fire-extinguishing systems (SOLAS regulation II-2/10.4 and FSS Code chapter 5) (IACS UI SC 263) (SSE 1/17/6) Not supported by SSE 1, it was questioned both the need for the UI and suggested that it exceeded the requirements of SOLAS II/ Load testing of hooks intended for the primary release of lifeboats (resolution MSC.81 (70), part 2, paragraph 5.3.4) - further revision to UI SC244 (SSE 1/17/7) Supported by SSE 1 and a draft MSC circular was prepared for submission to MSC 94. Embarkation station and stowage location of the liferaft as required by SOLAS regulation III/ (IACS UI SC 213) (SSE 1/17/8) This was agreed with slight amendments, notably the deletion of paragraph 6 as SSE 1 could not support the removal of the requirement for the application of 10% of trim to the calculation of length of the embarkation ladder. A draft MSC circular was prepared for consideration at MSC 94. Amendments were also made to the text to ensure that it reflected the need to illuminate the embarkation point. Release Operation of the CO2 System (FSS Code, chapter 5) (IACS UI SC132) (SSE 1/17/9) SSE 1 fully supported this item and a draft MSC circular was prepared for consideration at MSC 94. Fixed foam fire extinguishing systems foam-generating capacity (FSS Code, chapter 6, paragraphs and ) (IACS UI SC 262) (SSE 1/17/10) The majority who commented supported the UI, however some had concerns that it had some ambiguity. IACS was requested to revise the interpretation and re-submit at SSE 2. IACS raised questions on the interpretations for the following matters:

6 6 The Fire Safety Systems (FSS) Code pertaining to the sizing of the pumps and pressure tank for automatic sprinkler systems (SSE 1/17/1) SSE 1 agreed that the approach detailed in paragraphs 5 & 6 of the paper were preferred and IACS was instructed to prepare a UI for submission to SSE 2. International Code for Fire Safety Systems (FSS Code) Fixed gas fire- extinguishing systems (chapter 5, paragraph ) and Fixed fire detection and fire alarm systems (chapter 9 paragraph 2.2.4) (SSE 1/17/11) There was much discussion as to whether the phrase at the end of the period referred to the last 30 minutes of the period specified in SOLAS or 30 minutes subsequent to the period specified in SOLAS with some delegates referencing discussions previously held in the FSS Working Group which supported the latter. No decisions were reached and SSE 1 requested more time to consider this. IACS was requested to submit two texts for consideration by SSE 2 as an IMO Interpretation rather than a UI. Installation of Manually-Operated Call Points in way of Bosun Stores (SSE 1/17/12) Many delegations supported the UI although some felt that it was unnecessary and others questioned the use of the term bosun s store (it was felt that this store or service space could have other names on some vessels). No decision was made and SSE 1 invited papers to be submitted to SSE 2 for consideration. Implementation of the FSS Code, chapter 14 Fixed Deck Foam Systems (SSE 1/17/13) SSE agreed to amend MSC Circ.1120 as proposed and prepared the amendment for MSC 94. Location of the fire main isolation valves in tankers under SOLAS regulation II-2/ (SSE 1/17/14) This submission was fully supported. Amendments to MSC Circ.1456 were prepared for consideration at MSC 94. DE 57/3/8 Revision of UI SC 145 regarding public address systems including request for clarification on the application of SOLAS regulation III/6 regarding the requirement for general emergency alarm and public address systems in ro-ro spaces. It was agreed that the PA system was necessary for ro-ro spaces in passenger ships but not cargo ships. IACS was asked to prepare the revisions to the UI and submit it to SSE 2. SOLAS regulation III/20.11 Periodic servicing of launching appliances and on-load release gear - further revision of UI SC144 (SSE 1/17/15). It was suggested that it was premature to discuss the UI until after MSC Circ.1206/Rev.1 was adopted at MSC 93. IACS was invited to reconsider the revision of the UI and resubmit it to SSE2. In addition, the following amendment to the convention was considered: Proposed amendments to MARPOL regulation I/12 (SSE 1/17) The amendments to MARPOL regulation I/12 as proposed by SSE1/17/16 & SSE1/17/16/Corr.1 were agreed in principle by SSE 1. The application for the amendments was determined as Ships constructed before [1 January 2017], shall be arranged to comply with regulation not later than the first renewal survey carried out on or after [1 January 2017] The draft amendments will be sent to MEPC 67 for approval. Any other business (agenda item 20) The following items were discussed under Any other business : Consideration of casualty reports (SSE 1/20) SSE 1 was reminded that a recent decision of IMO Council was that Sub-Committees should only consider Casualty Reports when there was a clear link to an existing output. Consideration of the amendments to the EmS Guidelines (SSE 1/20/1) SSE 1 noted the outcome of DSC 18 and there was no further discussion. Clarification of a vague expression in chapter 9 of the FSS Code on Fixed Fire Detection and Fire Alarm Systems (SSE 1/20/2) SSE 1 noted the paper and there was no discussion Inspection and Maintenance of Fixed Carbon Dioxide Fire-Extinguishing System (SSE 1/20/3)

7 7 While some delegations felt that the proposal to carry out an internal inspection of the control valves in the delivery manifold of the fixed carbon dioxide fire-extinguishing systems the valves had merit, others reported that the disassembling of these valves in the field posed real practical difficulties. Comments on the Guidelines for evaluation and replacement of lifeboat on load release mechanisms (MSC.1/Circ.1392) referred to in SOLAS regulation III/1.5 (SSE 1/20/4). The proposed amendments were not supported, and no further action will be taken by SSE. Possible errors in the International Code for Application of Fire Test Procedures, 2010 (2010 FTP Code) (SSE 1/20/5) SSE 1 agreed that the error existed and that the period mentioned should be 3 minutes. An erratum will be issued. Inert gas system using nitrogen generator (SSE 1/INF.7 SSE noted the information provided. SSE1/INF 8 Development of a Mandatory Code for Ships Operating in Polar Waters: Review of Chapters 8 & 9. SSE was reminded that these two Chapters of the Code were finalised at SDC 1 and had been referred to SSE 1 to consider whether it is necessary to develop performance standards. It was decided that performance standards may be required but until the term polar service standard has been defined these cannot be determined. Delegations with more detailed comments were asked to submit papers to MSC93. DE 57/2/2 Draft International Code of Safety for Ships using Gas or other Low- Flashpoint Fuels SSE1 decided against additional LSA requirements for IGF ships. DE 57/23/1 Application of paragraphs , , and of the 2000 HSC Code SSE 1 agreed with the proposal that an alternative to the rescue boat should be carried on High Speed Crafts (HSC) of less than 30 metres in length, noted the possible discrepancy and invited IACS to bring this to the attention of MSC 94. MSC 90/9/2 Safe working load and lowering test load for launching appliances SSE 1 discussed whether the davits on cargo vessels needed to be re-tested to take account of the additional maximum weight of lifeboats. It was decided that if the safe working load of the davit is not exceeded by the maximum weight of the lifeboat then it is not necessary to re-test it. If this is not the case and the maximum weight of the lifeboat exceeds the safe working load of the davit, then the davit should be re-tested. No further action was deemed necessary. MSC 57/23/5 Scope of Application and drafting of amendments to the LSA Code The Sub-Committee was advised that the LSA Code is outside the scope of work currently under consideration by MSC and decided to instruct the LSA Correspondence Group to consider this paper and advise SSE 2 accordingly. DE 57/23/2 Amendments to the Guidelines for construction, installation, maintenance, and inspection/survey of means of embarkation and disembarkation (MSC.1/Circ.1331) Although there was some general support for the proposals SSE has no planned output referring to this item and was advised that no action could be taken without it going first to MSC. DE 57/23/4 Correction to resolution MSC.81 (70) as revised by resolution MSC.323 (89) It was noted that the testing requirements in resolution MSC.81 (70) had some errors which were revised by resolution MSC.323 (89). The proposal that a further revision of paragraph MSC.81(70) was necessary was fully supported. A corrigendum will be issued to modify paragraph of part 1 of resolution MSC.81 (70) as follows: "When inherent buoyant material is required, the material should be subjected to the tests prescribed in 2.6 (but with exclusion of 2.6.8), except that in high-octane petroleum spirit should be substituted for diesel oil." MSC 92 /INF.10 Testing of automatic sprinkler systems on passenger ships SSE noted the information on findings from the testing of automatic sprinklers on passenger ships and expressing the view that the scope of testing in MSC.1/Circ.1432 may not adequately assess the actual condition of automatic sprinkler systems. Member States were requested to advise the results of the application of MSC.1/Circ.1432.

8 8 FP 56/20/3 Proposed consequential amendments to SOLAS regulation II-2/18.5 and related instruments No discussion took place. SSE 1 was invited to consider this item at the next session and members were encouraged to submit papers..
