SUBDIVISION AND DAMAGE STABILITY 
Amendments to SOLAS regulations II-1/6 and II-1/8-1 
Computerised stability support for the master in case of flooding for existing passenger ships 
Guidelines on safe return to port for passenger ships 
Amendments to SOLAS chapter II-1 and associated guidelines on damage control drills for passenger ships 

(items 3, 4, 5 and 9) ( WP 4) 

The Sub-Committee: 

  • agreed to finalised draft amendments to SOLAS regulations II-1/1, II-1/2 and II-1/35-1, with a view of approval by MSC 96 and subsequent adoption, related to the application of these new regulations (expected to enter into force in 2020 and apply to new ships, with the three dates system) 
  • agreed to draft amendment to SOLAS regulation II-1/6, related to the survivability of passenger ships, and agreeing on a compromise increased R index 
  • agreed to draft amendments to chapter 2 of the 2008 SPS Code, with a view of adoption by MSC 96. It replaces the SPS Code reference to SOLAS regulation II-1/6.2.3 with the current R so that the draft amendments to SOLAS regulation II-1/6 shall not apply to special purpose ships 
  • agreed to draft amendment to SOLAS regulations II-1/1.2, to draft new SOLAS regulation II-1/19-1 and to draft amendments to regulations III/1.4, III/30 and III/37, to establish requirements for damage control drills for all passenger ships 
  • agreed to continue the work on availability of a passenger ship's electrical power supply in cases of flooding from side raking damage (Amendments to SOLAS regulations II-1/6 and II-1/8-1) (double hull in way of engine rooms or equivalent protection) 
  • agreed to the finalised draft Revised guidelines on operational information for masters of passenger ships for safe return to port and instruct the Secretariat to prepare the draft associated MSC circular, with a view of approval by MSC 96 as an MSC Circular updating MSC.1/Circ.1400 
  • noted that the draft amendments to the Explanatory Notes remain to be finalised, while the package of draft amendments to Ch.II-1 is completed and submitted to MSC. 

INTACT STABILITY 
Finalisation of second-generation intact stability criteria 
Amendments to part B of the 2008 IS Code on towing, lifting and anchor handling operations 

(items 6 & 7) (WP5) 

The Sub-Committee: 

  • noted the minor improvements/adjustments made to the finalized draft amendments to the 2008 IS Code regarding vulnerability criteria and the standards (levels 1 and 2) for pure loss of stability and surf-riding/ broaching 
  • agreed, in principle, to the draft amendments to the 2008 IS Code regarding vulnerability criteria and the standards (levels 1 and 2) related to dead ship condition and excessive accelerations 
  • noted the progress made by the working group on the development of the draft explanatory notes for pure loss of stability, parametric roll, surf-riding / broaching, dead ship condition and excessive acceleration failures 
  • noted the progress made on the development of the draft Guidelines of direct stability assessment procedures and operational limitation/guidance 
  • agreed to draft amendments to part B of the 2008 IS Code regarding vessels engaged in towing and lifting operations for submission to MSC 96 for approval 

FIRE PROTECTION 
Amendments to SOLAS and FSS Code to make evacuation analysis mandatory for new passenger ships and review of the Recommendation on evacuation analysis for new and existing passenger ships 
Guidelines for use of Fibre Reinforced Plastic (FRP) within ship structures 

(Items 8 and 17) (WP 6) 

The Sub-Committee: 

  • agreed to draft amendment to paragraph 2.1.2.2.2.1 of chapter 13 of the FSS Code, that clarifies the crew distribution in public spaces, for submission to MSC 96 for approval and subsequent adoption 
  • agreed to the draft Revised guidelines on evacuation analyses for new and existing passenger ships, and the associated MSC circular, for submission to MSC 96 for approval 
  • in this context, noted that the WG agreed that the company and/or the Administration should decide the way of presenting the outcome of the evacuation analysis to the crew (eg in the ISM system) 
  • in this context, noted that the group further developed the simulation case for Open Decks in the draft Revised guidelines on evacuation analyses for new and existing passenger ship 
  • also agreed that their is no intention that ro-ro passenger ships constructed before the date of approval of these Revised Guidelines and already evaluated (with MSC.1/Circ.1033 or 1238) will need to be re evaluated using these Revised Guidelines. 
  • agreed to establish a Correspondence Group on Development of Interim Guidelines for use of Fibre Reinforced Plastic (FRP) elements within ship structures 


CARRIAGE OF MORE THAN 12 INDUSTRIAL PERSONNEL ON BOARD VESSELS ENGAGED ON INTERNATIONAL VOYAGES 
Classification of offshore industry vessels and a review of the need for a non-mandatory code for offshore construction support vessels 
Mandatory instrument and/or provisions addressing safety standards for the carriage of more than 12 industrial personnel on board vessels engaged on international voyages 

(Items 11 and 16) (WP 7) 

The Sub-Committee: 

  • agreed to forward the eight options identified by the WG on the regulatory regimes and procedures for transporting industrial personnel and table on comparison of criteria within proposed options, together with the group's views under criteria "Scope", "Time frame/interim/mandatory", "Existing code/new code", "Definition of Industrial Personnel" and "Ship type", "Road map", "Advantages", "Disadvantages" and "Potential way forward" to MSC 96 for consideration 



AMENDMENTS TO THE 2011 ESP CODE
