7 Documentation

  7.1 Because the alternative design process may involve substantial deviation from the regulatory prescribed requirements, the process should be thoroughly documented. This provides a record that will be required if future design changes to the ship are proposed or the ship transfers to the flag of another State and will also provide details and information that may be adapted for use in future designs. The following information should be provided for approval of the alternative design or arrangements:

• .1 scope of the analysis or design;

• .2 description of the alternative design(s) or arrangements(s), including drawings and specifications;

• .3 results of the preliminary analysis, to include:

  • .3.1 members of the design team (including qualifications) ;

  • .3.2 description of the trial alternative design and arrangements being evaluated;

  • .3.3 discussion of affected SOLAS chapter II-2 regulations and their functional requirements;

  • .3.4 fire hazard identification;

  • .3.5 enumeration of fire hazards;

  • .3.6 selection of fire hazards; and

  • .3.7 description of design fire scenarios;

• .4 results of quantitative analysis:

  • .4.1 design fire scenarios:

    • .4.1.1 critical assumptions;

    • .4.1.2 amount and composition of fire load;

    • .4.1.3 engineering judgements;

    • .4.1.4 calculation procedures;

    • .4.1.5 test data;

    • .4.1.6 sensitivity analysis; and

    • .4.1.7 time-lines;

  • .4.2 performance criteria;

  • .4.3 evaluation of trial alternative designs against performance criteria;

  • .4.4 description of final alternative design and arrangements;

  • .4.5 test, inspection, and maintenance requirements; and

  • .4.6 references.

  7.2 Documentation of approval by the Administration and the following information should be maintained onboard the ship at all times:

• .1 scope of the analysis or design, including the critical design assumptions and critical design features;

• .2 description of the alternative design and arrangements, including drawings and specifications;

• .3 listing of affected SOLAS chapter II-2 regulations;

• .4 summary of the results of the engineering analysis and basis for approval; and

• .5 test, inspection, and maintenance requirements.

  7.3 Reporting and approval forms

  7.3.1 When the Administration approves alternative design and arrangements for fire safety, pertinent technical information about the approval should be summarized on the reporting form given in appendix B and should be submitted to the International Maritime Organization for circulation to the Member Governments.

  7.3.2 When the Administration approves alternative design and arrangements on fire safety, documentation should be provided as indicated in appendix C.
