5926187197 9f54d6b30e C

(WASHINGTON) — The International Maritime Organization (IMO) Subcommittee on Ship Systems and Equipment (SSE) held its ninth session Feb. 27- March 3 in London. Brandi Baldwin, chief of the Coast Guard’s Lifesaving and Fire Safety Division in the Office of Design and Engineering Standards, led the U.S. delegation, comprised of members from the Coast Guard and technical advisers from government and private sectors.

Key topics discussed at SSE 9 were:

• New requirements for the ventilation of survival craft.
• Development of amendments to the LSA Code (life-saving appliances) to revise the lowering speed of survival craft and rescue boats for cargo ships.
• Revision of SOLAS Chapter III and the LSA Code.
• Review of SOLAS Chapter II-2 and associated codes to minimize the incidence and consequences of fires on ro-ro spaces and special category spaces of new and existing ro-ro passenger ships.
• Development of amendments to the LSA Code for thermal performance of immersion suits.
• Development of amendments to the LSA Code and resolution MSC.81(70) to address the in-water performance of SOLAS life jackets.
• Development of amendments to SOLAS Chapter II-2 and the FSS Code (fire safety systems) concerning detection and control of fires in cargo holds and on the cargo deck of containerships.
• Development of amendments to SOLAS Chapter II-2 and MSC.1/Circ.1456 addressing fire protection of control stations on cargo ships.
• Revision of the Code of Safety for Diving Systems (resolution A.831(19)) and the guidelines and specifications for hyperbaric evacuation systems (resolution A.692(17)).
• Validated model training courses.
• Unified interpretation of provisions of IMO safety, security and environment-related conventions.
• Development of provisions to prohibit the use of firefighting foams containing perfluorooctane sulfonic acid (PFOS) for firefighting on board ships.
• Amendments to the LSA Code concerning single fall and hook systems with on-load release capability.

New requirements for ventilation of survival craft

The subcommittee agreed to finalize draft amendments for ventilation requirements for totally enclosed lifeboats, which are expected to be adopted at Maritime Safety Committee (MSC) meeting 107. This will facilitate a planned entry into force date of Jan. 1, 2026. Regarding partially enclosed lifeboats and life rafts, the subcommittee agreed that more discussion on the need for new ventilation requirements is necessary. The subcommittee intends to discuss this further during SSE 10.

Development of amendments to the LSA Code to revise the lowering speed of survival craft and rescue boats for cargo ships

The subcommittee agreed to draft amendments to the LSA Code regarding minimum safe lowering speed and noted that the draft amendments should be applied to new installations only. Regarding maximum safe lowering speed, the subcommittee agreed in principle to the draft amendments to the LSA Code and recommended to MSC 107 that the scope of this output should be expanded accordingly.

Revision of SOLAS Chapter III and the LSA Code

During this session, the subcommittee supported terms of reference for a possible subsequent in-person intersessional working group that will focus on developing the hazard identification matrix in support of this agenda item. A subsequent intersessional working group will first require authorization by the Maritime Safety Committee.

Review of SOLAS Chapter II-2 and associated codes to minimize the incidence and consequences of fires on ro-ro spaces and special category spaces of new and existing ro-ro passenger ships

The subcommittee finalized draft amendments to SOLAS Chapter II-2 and the FSS Code concerning fire safety on ro-ro passenger ships. Work at this session included finalizing proposed draft amendments to the FSS Code which add relevant EN 54 and IEC standards to the code and allow for linear heat detectors to be used as an alternative to point heat detectors on all ships (this was previously limited to ro-ro passenger ships). The subcommittee also finalized draft amendments to MSC.1/Circ.1430/Rev.2 concerning the term “free height.” All amendments have a view to submission for approval by MSC 107.

Development of amendments to the LSA Code for thermal performance of immersion suits

The subcommittee finalized draft amendments to MSC.81(70) covering prototype tests for immersion suits, which clarified a time requirement for stopping a test under certain conditions. It was noted that additional test requirements are being developed and may need to be incorporated in the future; hence the subcommittee recommended the output remain on the agenda for SSE 10.

Development of amendments to the LSA Code and resolution MSC.81(70) to address the in-water performance of SOLAS life jackets

The subcommittee finalized draft amendments to the LSA Code, MSC.81(70) and test forms which will be sent to MSC 107 for approval and subsequent adoption. These amendments clarified portions of the water performance test, and reflected these changes in the test forms.

Development of amendments to SOLAS Chapter II-2 and the FSS Code concerning detection and control of fires in cargo holds and on the cargo deck of containerships

The subcommittee noted that an FSA experts group will be established to review the outcome of a Cargosafe FSA study as well as two papers that were submitted by Qatar, the Republic of Korea and others under this agenda item this session. This item will remain on the agenda for consideration during SSE 10.

Development of amendments to SOLAS Chapter II-2 and MSC.1/Circ.1456 addressing fire protection of control stations on cargo ships

The subcommittee finalized draft amendments to SOLAS regulation II-2/7.5.5 and MSC.1/Cir.1456 with respect to the protection of accommodation and service and control stations. The subcommittee also noted that the work on this output had been completed.

Revision of the Code of Safety for Diving Systems (resolution A.831(19)) and the guidelines and specifications for hyperbaric evacuation systems (resolution A.692(17))

The subcommittee finalized the draft MSC resolution on “International Code of Safety of Diving Operations, 2023 (2023 Diving Code),” which will be sent to MSC 107 for approval and adoption.

Validated model training courses

The subcommittee reviewed Model Course 3.03, Survey of Machinery Installations, and agreed to a draft revision of the course in principle with a view to validation. The next model course to be reviewed is Model Course 3.04, Survey of Electrical Installations, this will be completed by a drafting group and be considered during SSE 10.

Unified interpretation of provisions of IMO safety, security and environment-related conventions

Eight unified interpretations were submitted and 13 carried over from SSE 9. Of these, four were agreed to, 10 were referred to correspondence groups and seven were not agreed to. The approved draft interpretations will be sent to MSC 107 for final approval. They cover several topics including separation of ducts from spaces, reliability of single essential propulsion components, cable and wiring in hazardous locations, and the use of LED torches in survival craft.

Development of provisions to prohibit the use of firefighting foams containing perfluorooctane sulfonic acid (PFOS) for firefighting on board ships

The subcommittee expects MSC 107 to adopt amendments to the FSS Code and SOLAS to ban PFOS. The working group discussed prohibiting other environmentally harmful foams besides PFOS and agreed to expand the output to be “Development of provisions to consider prohibiting the use of fire-fighting foams containing fluorinated substances, in addition to PFOS for firefighting on board ships,” pending approval from MSC 107.

Amendments to the LSA Code concerning single fall and hook systems with on-load release capability

The subcommittee agreed to draft amendments to the LSA Code regarding single fall and hook systems which will be sent to MSC 107 for approval and subsequent adoption by MSC 108.

Correspondence groups established

The following correspondence groups were established at this session:

• The Life-Saving Appliances Correspondence Group will continue work on unified interpretation on launching rescue boats on cargo ships and development of resolution MSC.402(96).
• The Fire Protection Correspondence Group will continue work on multiple unified interpretations as assigned during this session and consider draft amendments to the Revised Guidelines for the Performance and Testing Criteria, and Surveys of Foam Concentrates for Fixed Fire-Extinguishing Systems (MSC.1/Circ. 1312).

Finally, the subcommittee re-elected U. Şentürk (Turkey) as chairman and elected C. Aliperta (Palau) as vice chairman. The 10nth session of the SSE is tentatively scheduled for March 4-8, 2024.
