Section 4 General requirements

Parent topic: Chapter 4 Life-Saving and Evacuation Arrangements

4.1 The Rules

4.1.1 The requirements are arranged in terms of four fundamental objectives which all contribute to the overall performance of the life-saving and evacuation arrangements, see Vol 3, Pt 2, Ch 4, 4.2 Life-saving and evacuation arrangements objectives.

4.1.2 Each of the four objectives has a series of Rule requirements attributed to them, these Rules are arranged in a ‘top-down’ manner such that the objective is stated as the highest level requirement. At the next level, a goal or series of goals, are detailed; the goals are then developed as performance requirements; and ultimately specified guidance where applicable.

4.1.3 In general, a system is to be compliant with the SOLAS - International Convention for the Safety of Life at Sea convention; however, where this cannot be achieved, the performance criteria, goals and objectives are to be satisfied by assignment of a Concession or through the application of an Alternative Design Justification Report, see the Naval Survey Guidance. The referenced SOLAS - International Convention for the Safety of Life at Sea Regulations to satisfy different Goals are provided for guidance purposes. Alternative standards consistent with the overall SOLAS - International Convention for the Safety of Life at Sea philosophy can be applied where the compliance with the objective can be demonstrated to an equivalent level to those in SOLAS - International Convention for the Safety of Life at Sea.

4.1.4 These Rules are based on the requirements of SOLAS Chapter III - Life-saving appliances and arrangements and all terms and definitions are referenced therein. All references to the Code refer to the LSA Code - International Life-Saving Appliance Code – Resolution MSC.48(66) .

4.1.5 The evacuation systems are to be designed so as to support evacuation of all personnel in a pre-determined time. Where a pre-determined time for evacuation is specified, based on the design and operational role of the ship then it is to be validated by full-scale trials or by a simulation acceptable to LR and the Naval Administration.

4.2 Life-saving and evacuation arrangements objectives

4.2.1 The objectives to be satisfied by all life-saving and evacuation systems are as follows:

  1. Evacuation Objective. Arrangements are to be provided to enable personnel to evacuate the ship safely and in a specified time, see Vol 3, Pt 2, Ch 4, 5 Evacuation of personnel.

  2. Personnel Protection Objective. Evacuated personnel are to be kept protected until such time as they can be rescued from the survival craft, see Vol 3, Pt 2, Ch 4, 6 Personnel protection.

  3. Rescue Objective. Every ship is to be suitably equipped to rescue personnel from the water, see Vol 3, Pt 2, Ch 4, 7 Rescue of personnel.

  4. Command and Control Objective. Every ship is to be equipped and manned so that command of all evacuation and life-saving situations can be maintained, see Vol 3, Pt 2, Ch 4, 8 Command and control.
