Ship Systems and Equipment IMO Sub-Committee 10 to 14 March 2014

The IMO’s Sub-Committee on Ship Systems and Equipment held its 1st session from Monday 10 through Friday 14 March 2014 under the chairmanship of Dr S Ota (JAPAN) and his Vice-Chair, Mr K Hunter (UK) both were subsequently re-elected for 2015.

2014.03.17 - Ship Systems and Equipment IMO Sub-Committee 10 to 14 March 2014

Three working groups (WG) and a drafting group (DG) were formed as follows:

  1. WG1       Fire Protection, Mr Eberly (USA)
  2. WG2       Life-Saving Appliances, Mr Yoshida (JAPAN)
  3. WG3       Onboard Lifting Appliances and Winches, Mr Lakeman (NL)
  4. DG1        Consideration of IACS Revised Unified Interpretations and proposed amendments to MARPOL Annex 1, Mrs Kristensen (NORWAY)

In general, among others, the following have been discussed during this meeting:

Ships Carrying Hydrogen And Compressed Natural Gas, Vehicles. WG1 produced a draft MSC Circular, subsequently agreed by the Sub-Committee for submission to MSC 93, which recommends that the shipper should provide a signed certificate or declaration that the vehicle fuel system, as offered for carriage, has been checked for leak-tightness and the vehicle is in proper condition for carriage prior to loading.

Smoke Control and Ventillation. The Sub-Committee noted WG 1’s considerations on development of a draft Performance Standard, that it would be best to first develop broad functional requirements to benchmark intended smoke control system objectives and then to develop a recommended list of action items as the basis for future work. This translates to possible amendments to SOLAS Chapter 11 – 2.

Developments Of Amendments To SOLAS Regulation 11 – 2/20 and Associated Guidance On Air Quality Management for Ventilation of Closed Vehicle Spaces, Closed Ro-Ro and Special Category Spaces. It was agreed that the air quality control system should not be applicable to the new SOLAS regulation 11 – 2/20-1 (requirement for vehicle carriers carrying motor vehicles with compressed hydrogen or natural gas in their tanks for their own propulsion as cargo) since the current SOLAS requirements consider gasoline and diesel as fuel only.

Sample Extraction Smoke Detection System in FSS Code. A draft Unified interpretation on the requirement for sample extraction in chapter 10 of the FSS code was agreed for submission to MSC 94.

Use o Flexible Bellows. Noting that flexible bellows (not made of steel or equivalent material) protect the ventilation duct most effectively, especially in that they absorb machinery vibration, it was agreed that a short length, not exceeding 600 mm, of flexible bellows constructed of combustible material may be used for connecting fans to the ducting in the air conditioning room;  this recommendation will be forwarded to MSC 93 for consideration.

Development of Life Safety Performance Criteria for Alternative Design and Arrangements for Fire Safety. It was decided to establish a Correspondence Group under the coordination of the US. It will seek to review available research, methodologies and standards vis-à-vis human exposure to fire effluent and consider whether safety margins in shore-side building design are adequate for use in ships.

2009 MODU Code. Draft amendments to the MODU Code were agreed for submission to MSC 94. These related to Practice musters and drills and in addition, a set of associated draft Guidelines on alternative methods for lifeboat drills on MODUs was developed.

GISIS Database Regarding the Evaluation of Hooks under the Requirements of MSC.1 / Circ.1392. The intent behind this MSC Circular is that existing on load release hooks are only re-approved when the function of the hook itself is safe without the use of additional operating mechanisms or devices similar to ‘fall preventer devices’.  Such devices should be considered as being in addition to, and not form part of, the original hook’s mechanism.

Development of Requirements for On-Board Lifting Appliances and Winches. In light of the number of accidents, the Sub-Committee noted WG 3s views on the need for further consideration of available data involving on-board lifting appliances and winches in order to determine the scope and application of measures necessary for potential future regulations. Based on presently available incident data, the following items were noted:

insufficient safety procedures in place

lifting hooks not engaging properly

training in operation and maintenance

operational and maintenance conditions that could induce failure of on-board lifting and winches, particularly that of wire rope

IACS Unified Interpretations (UIs). This is a continuous item on the biennial agenda, established by MSC 78, so that IACS can submit any newly developed or updated UIs for consideration by the Sub-Committee. Assembly 28 expanded the output to include all the proposed UIs to provisions of IMO safety, security, and environment-related Conventions. Some of them are mentioned below:

Agreement to a draft UI and associated draft MSC circular (for approval at MSC 94) on the load testing of hooks intended for the primary release of lifeboats.

The expectation that MSC 93 will adopt mandatory requirements for periodic servicing and maintenance of launching appliances and on-load release gear however there is no indication as to limitation regarding service providers.

The establishment of a drafting group to finalise the draft text of proposed amendments to MARPOL regulation I/12 and prepare consequential amendments to relevant UIs for approval at MEPC 67.

Agreement of a draft UI and associated draft MSC Circular on the embarkation station and stowage location of the life-raft together with adequate means of illumination.

The forwarding to MSC 94 of a draft UI relating to the provisions in Chapter 9 of the FSS Code on Fixed Fire Detection and Fire Alarm Systems and likewise for Chapter 5, a draft UI relating to the release operation of the CO2 System.

An invitation to IACS to prepare a draft MSC circular on fixed gas fire-extinguishing systems and fixed fire detection and fire alarm systems.  This will seek to clarify the number of setting points to the discharge control for the fire-extinguishing medium and also, the time period of the power supply to the latter system.

The Polar Code. It was generally agreed that additional performance or test standards may be necessary but that detailed discussion should not be started until after MSC 93 has finalised the Polar Code.
