Section 4 General requirements

Parent topic: Chapter 5 Safety of Navigation and Communication

4.1 The Rules

4.1.1 The requirements are arranged in terms of three fundamental objectives which all contribute to the overall performance of safety of navigation and communications arrangements, see Vol 3, Pt 2, Ch 5, 4.2 Safety of navigation and communications objectives.

4.1.2 Each of these three 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 requirement; and ultimately specified guidance.

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 Regulations to satisfy different goals are provided for guidance purposes. Alternative standards consistent with the overall SOLAS philosophy can be applied where the compliance with the objective can be demonstrated to an equivalent level to those in SOLAS.

4.2 Safety of navigation and communications objectives

4.2.1 The safety of navigation and communications objectives to be satisfied by all ships is as follows:

  1. Communication Objective. Every ship is to be capable of communication to avert unnecessary danger to itself and other ships in the vicinity during normal and emergency conditions, see Vol 3, Pt 2, Ch 5, 5 Safety of communication.

  2. Safety of Navigation Objective. Every ship is to be arranged with the necessary equipment to facilitate safe and effective navigation, see Vol 3, Pt 2, Ch 5, 6 Safety of navigation.

  3. Equipment Arrangements Objective. All navigation and communications equipment is to be arranged to allow safe and effective task performance, see Vol 3, Pt 2, Ch 5, 7 Safety of navigating and communication equipment arrangements.
