General requirements

This section explains the general requirements. The section states to which vessels these rules apply, and on which underlying regulations these rules are based, such as SOLAS chapter 4 & 5 and COLREGS. It states the information plans and documentation which needs to be provided to LR in order to start the notation process. Additionally, this section highlights certain definitions which are applicable in other sections of this chapter, such as Workstation, Navigation workstation, Conning position, Main steering position, and Voyage planning workstation.

The requirements for navigational arrangements and integrated bridge systems are documented in Lloyd’s Register’s Rules and Regulations for the Classification of Ships, July 2022 - Part 7 Other Ship Types and Systems - Chapter 9 Navigational Arrangements and Integrated Bridge Systems - Section 1 General requirements – Section 2 Physical conditions – Section 3 Workstations – Section 4 Systems. All vessels complying with section 1 to 4 of the requirements of PT 7, Ch 9, will be eligible for the notation NAV1.

It is important to note that the earlier mentioned sections do not state all performance standards that the equipment is required to meet. The performance standards are documented in e.g. SOLAS Chapter V, Regulation 18: Approval, surveys and performance standards of navigational systems and equipment and voyage data recorder, and in regulation 19 - Carriage requirements for shipborne navigational systems and equipment. On the second part there is a comparison to existing DNV rules of the engine room systems.
