Navigation Audit Project – Bridge & Navigational Safety
Independent technical navigation audit project covering bridge navigation equipment, navigational procedures, safety systems, operational records, documentation and compliance within the agreed technical inspection scope.
Navigation Audit Project Overview
A navigation audit project provides an independent technical assessment of a vessel's bridge and navigational arrangements, with particular attention to navigation equipment condition, operational readiness, bridge procedures, documentation, records and navigational safety.
PAMS Pacific Admiralty Maritime Services conducts navigation audit projects as independent marine technical consultancy assignments. The scope is adapted to the vessel type, navigation equipment configuration, operational profile, available documentation and the client's technical requirements.
The project may combine physical bridge inspection, equipment verification, document review, operational checks, navigation record assessment and identification of technical or procedural deficiencies.

| AIS | Equipment status, configuration, static and dynamic data, available test information and operational readiness. |
| Gyro Compass | Available heading information, repeaters, alarms, maintenance records and comparison with other heading references. |
| Magnetic Compass | Physical condition, deviation information, correction arrangements and available certification or records. |
| GNSS / GPS | Equipment status, displayed information, available alarms, antenna arrangements and operational readiness. |
| Echo Sounder | Display, operational indications, depth information, alarm settings and available maintenance records. |
| Speed Log | Equipment status, indications, alarms and available calibration or maintenance information. |
| BNWAS | Equipment condition, operational controls, alarm indications and available testing records. |
| Navigation Lights | Physical condition, operational indications, control arrangements and available maintenance records. |
GMDSS & Bridge Communication Assessment
Where included in the agreed audit scope, GMDSS and bridge communication arrangements may be reviewed as part of the overall navigational safety assessment.
GMDSS Equipment
Review of available GMDSS equipment condition, certification, maintenance information, operational indications and relevant records.
Radio Documentation
Review of radio certificates, maintenance records, test records, battery information and other applicable documentation.
Emergency Communication
Assessment of emergency communication arrangements and the availability of relevant procedures and operational information.
Bridge Communication
Review of communication arrangements supporting safe bridge operations, including internal and external communication systems where applicable.
Navigation Documentation Review
Technical documentation is an important component of the navigation audit because equipment condition and operational readiness should be considered together with maintenance, certification and operating records.
Certificates
Review of relevant navigation equipment certificates, statutory documentation and available certification records.
Maintenance Records
Review of planned maintenance, equipment defects, corrective actions, service reports and outstanding technical items.
Navigation Manuals
Review of applicable navigation procedures, equipment manuals, bridge instructions, standing orders and related documentation.
Navigation Records
Review of relevant passage plans, navigation records, equipment testing records, chart updates and bridge logs.
Navigation Audit Project Methodology
Pre-Audit Documentation Review
Available vessel particulars, navigation equipment lists, certificates, maintenance records and relevant procedures are reviewed before or during the attendance.
Bridge Inspection
Physical examination of accessible bridge navigation equipment, controls, displays, associated systems and safety arrangements.
Operational Verification
Equipment operation may be observed or functionally checked where safe, practicable, permitted and included within the agreed project scope.
Records Cross-Check
Physical observations are compared with available certificates, maintenance records, testing documentation and navigation procedures.
Technical Findings
Observable deficiencies, technical concerns, documentation gaps and operational issues are categorized according to their significance and the agreed reporting methodology.
Final Technical Report
Findings are presented in a structured technical report with supporting observations, photographs where applicable and recommendations for further attention.
