Section 3 Documentation required for design review

3.1 System Operational Concept

3.1.1 The design intent of any escape and emergency access arrangements 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, ESC, ESC★ or ESC★★. 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 escape and emergency access systems/equipment to include environmental conditions together with a description of any escape and emergency access scenarios and their development and application in the design.

  3. Manning levels 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 LR. The Design Disclosure is to include, but is not limited to:

  1. A description of the escape regime, i.e. estimated times to designated places of safety in all foreseeable conditions. This is also to include a declaration of all designated places of safety.

  2. A statement of all design standards used in the design, manufacture, installation and testing of escape and emergency access systems.

  3. 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.

  4. Details of the proposed survey and maintenance regime.

  5. Evidence of compliance with the Objectives and Goals defined in Vol 3, Pt 2, Ch 3, 5 Escape of personnel and Vol 3, Pt 2, Ch 3, 6 Emergency access. This may be in the form of compliance with any specified guidance, 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.

    1. If applying for SOLAS, follow Vol 3, Pt 2, Ch 3, 5 Escape of personnel and Vol 3, Pt 2, Ch 3, 6 Emergency access;

    2. If applying for NSC, follow Vol 3, Pt 2, Ch 3, 6 Emergency access.

  6. 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.

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

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