1.1.1 The
                                 purpose of this Chapter is to provide a methodology for confirming
                                 that the arrangements on board a naval ship provide for navigation
                                 and communication equipment and arrangements which provide for safe
                                 and effective task performance and to meet the requirements of international
                                 regulations.
                              
                              
                              
                            
                           
                           
                           
                           
                           
                           
                              
                              
                              1.1.3 In general,
                                 demonstration of satisfactory levels of safety of navigation and communication
                                 will be achieved through compliance with the relevant requirements
                                 of these Rules and the documents referenced therein. Where navigation
                                 and communication arrangements deviate from the technical requirements
                                 of this chapter they are to be suitable to satisfy the objectives
                                 of and goals of this Chapter.
                              
                              
                              
                            
                           
                           
                           
                              
                              
                              1.1.4 In addition
                                 to the requirements for ships to be furnished with the necessary equipment
                                 for effective navigation and communication, SOLAS requires the contracting
                                 Governments to provide certain shore-based facilities and services.
                                 These services assist the ships in maintaining effective navigation
                                 and communication. It is beyond the scope of these Rules to mandate
                                 that a Government is to provide such services, however it must be
                                 noted that they are an essential part of the ship’s operation.
