Section 3 Documentation required for design review

Parent topic: Chapter 2 Fire Protection

3.1 System Operational Concept

3.1.1 The design intent of any fire protection system is to be submitted in the form of a System Operational Concept and is to include but not be limited to:

  1. The required class notation, FIRE, FIRE★ or FIRE★★. If a military distinction (MD) notation is required this is also to be declared, see Vol 1, Pt 1, Ch 2, 3.8 Military Distinction notations.

  2. Details of the intended mode of operation of the fire protection systems/equipment to include environmental conditions together with a description of any fire scenarios and their development and application in the design.

  3. Manning levels, drills, exercises and operator competencies/authorisations required.

  4. Indication of whether or not alternative design assessment is being sought, if the proposed design deviates from the specified guidance identified in these Rules.

The System Operational Concept is to be agreed by the designer and Owner, see also Vol 3, Pt 2, Ch 1, 2.3 Documentation required for design review 2.3.2.

3.2 Design disclosure

3.2.1 In addition to submission of an acceptable System Operational Concept, a Design Disclosure is required for submission to and acceptance by Clasifications Register (hereinafter referred to as 'LR'). The Design Disclosure is to include, but is not limited to:

  1. A statement of all design standards used in the design, manufacture, installation and testing of fire protection systems.

  2. A proposed list of all surveyable items together with any additional recommendations from equipment/component manufacturers. Evidence is also to be provided that all surveyable items of equipment have approval certificates.

  3. Details of the proposed survey and maintenance regime.

  4. Evidence of compliance with the Objectives and Goals defined in Vol 3, Pt 2, Ch 2, 5 Fire prevention. This may be in the form of compliance with specified guidance/technical references, Concessions, Alternative Design Justification Reports or an acceptable combination of all three. See also Vol 3, Pt 2, Ch 1, 2.3 Documentation required for design review and Vol 3, Pt 3, Ch 1 Pollution Prevention.

  5. Details of the Hazard Identification process and Class related hazards are to be submitted. A hazard identification system is to be in place at the design stage whereby all hazards identified are recorded. If application of these Rules has been identified as a hazard avoidance/mitigation measure, then details are to be submitted.

  6. Details of equipment configurations that are safe for operators and users.

  7. Details of the proposed test procedure required to demonstrate functionality at the time of commissioning.

  8. Details of system interaction, see Vol 3, Pt 2, Ch 2, 10 System interaction.

3.3 Plans

3.3.1 To support the Design Disclosure and for the purposes of assessing compliance with design requirements, for inspection installation and testing, guidance on the plans and details to be submitted for assessment and review are detailed in Vol 3, Pt 2, Ch 2, 3.3 Plans 3.3.2 and Vol 3, Pt 2, Ch 2, 3.3 Plans 3.3.4.

3.3.2 For fire safety arrangements, the following plans and information:

  1. A statement of the method of structural fire protection adopted and prevention of fire spread.

  2. A general arrangement plan showing main fire zones, escape routes and the fire compartmentalisation bulkheads and decks within main fire zones, including the machinery spaces, magazine spaces, equipment spaces, vehicle and aircraft spaces, accommodation areas, galleys, paint stores, inflammable substance stores, navigating bridge, weapon/aircraft operating/ control rooms, store rooms, fuel tanks, fire-fighting control room and emergency generators. The plan should also include location of fire command and control stations. Where fire parties are utilised, the location of each control station in each fire zone is to be indicated.

  3. A plan showing the details of construction of the fire protection bulkheads and decks and the particulars of any surface laminates employed.

  4. Copies of certificates of any approval in respect of fire divisions, non-combustible materials and materials having low flame spread properties, etc. which are to be used but have not been approved by LR.

  5. A plan showing the construction and operation of fire doors.

  6. A ventilation plan showing ducts, any smoke extractor facilities and any dampers in them, and the position of controls for operation.

  7. A plan showing the location and arrangement of the emergency stop for flammable oil unit pumps and for closing the valves on pipes from flammable oil tanks.

  8. An arrangement plan of the fire alarms if applicable.

3.3.3 For fire-extinguishing arrangements, the following plans and information:

  1. A general arrangement plan showing the location of all the fire-fighting equipment including the fire extinguishing water system, the fixed fire-extinguishing systems in magazines, vehicle and aircraft spaces, on deck and in the machinery spaces; the disposition of the portable and non-portable extinguishers and the types used; and the position and details of the fire-fighters’ outfits.

  2. A plan showing the layout and construction of the fire extinguishing water system, including all the designated fire pumps, isolating valves, pipe sizes and materials, the international shore connections and the cross-connections to any other systems.

  3. A plan showing details of each fixed fire-fighting system, including calculations for the quantities of the media used and the proposed rates of application.

  4. A plan showing any sprinkler and/or detection equipment locations, as applicable.

  5. Details of fire parties and availability of fire-fighters’ outfits.

3.3.4 A fire control plan that is to be permanently exhibited for the guidance of the ship's crew, showing clearly for each deck the control stations, the various fire sections together with particulars of the fire detection and alarm systems, the sprinkler installation, the fire-extinguishing appliances, means of access to different compartments, decks, etc. the ventilating system, including particulars of the fan control positions, the position of dampers and identification numbers of the ventilating plans serving each station.
