The 0400-0800 watch is just ending as the vessel approaches the pilot station at Mundra Port. The Master enters the bridge, not with his usual coffee, but with a thick folder and a grim look. "The company is sending an internal auditor for a remote navigation audit, and we have a SIRE 2.0 inspection scheduled for the next port," he tells you. As the Second Officer and the designated Navigation Officer, the weight of the bridge’s compliance rests squarely on your shoulders. It is no longer enough to simply draw a line from Point A to Point B; you must prove that every mile of that journey was planned, executed, and monitored according to the highest safety standards.
A navigation audit is not a "gotcha" game played by the office. It is a critical health check of your bridge team’s culture. For a Second Mate, mastering the navigation audit is the difference between a smooth career progression toward Chief Mate and a stressful contract filled with deficiency reports.
The Foundation: Berth-to-Berth Passage Planning
The most common observation in any navigation audit—whether internal or by a Port State Control (PSC) officer—is a flawed Passage Plan. An effective audit starts with verifying that the plan is truly Berth-to-Berth.
Your plan must be executed on the ECDIS but backed by a comprehensive appraisal. Check that you have accounted for the latest T&P (Temporary and Preliminary) Notices. Many Second Mates forget to plot these on the ECDIS, or they fail to delete expired ones. During your self-audit, verify that the UKC (Under Keel Clearance) calculation includes factors like Squat, increase in draft due to rolling/pitching, and the specific gravity of the water.
In the Indian context, if you are transiting the Gulf of Khambhat or the Hooghly River, your passage plan must reflect the extreme tidal ranges and siltation issues specific to these regions. Auditors look for evidence that the OOW (Officer of the Watch) has read and understood the Master’s Standing Orders and the specific Bridge Order Book for that voyage. Ensure every officer has signed the plan before the voyage commences.
ECDIS Management and Safety Settings
In 2025, the ECDIS is the centerpiece of any navigation audit. An auditor will immediately look at your Safety Settings. You must be able to justify why you chose a specific Safety Contour and Safety Depth.
A common mistake is setting the Safety Contour equal to the Safety Depth without considering the available depth increments on the ENC (Electronic Navigational Chart). If your required Safety Contour is 10.5 meters, the ECDIS will default to the next deeper contour (e.g., 15 meters) available on the chart. You must demonstrate that you understand how this affects the "gray area" on your display.
Check your CATZOC (Category Zone of Confidence) settings. If you are navigating in areas with a low CATZOC (like certain stretches of the Indian Ocean or coastal areas near Kakinada), your XTD (Cross Track Distance) and safety margins must be wider. During your audit, pull up the Check Route function. If there are 200 ignored alarms for "Caution Area" or "Deep Water Route," the auditor will flag it as poor passage monitoring. You must review every alarm and document why it was deemed acceptable.
Bridge Equipment and Logbook Consistency
The Bridge Log Book is a legal document. Auditors perform "vertical audits," where they cross-reference the logbook entries with the VDR (Voyage Data Recorder), the AIS data, and the ECDIS playback.
If the logbook says "Testing of Bridge Equipment carried out one hour prior to arrival at JNPT," but the ECDIS shows the vessel was still at full sea speed with no steering gear tests recorded on the course recorder, you have a major non-conformity.
As the Second Officer, you must audit the following:
* Magnetic Compass Error Book: Ensure errors are taken at least once a watch, or after every major course change. Inconsistent entries are a red flag.
* GMDSS Logbook: Verify that daily, weekly, and monthly tests are not just ticked off, but actually performed. Check the DSC reserve source of energy (batteries) and ensure the entries match the physical battery readings.
* Chronometer Log: Ensure the error is tracked consistently. Even in the age of GPS, the Directorate General of Shipping (DGS) and MMD examiners expect a Second Mate to maintain traditional time-keeping records.
The Human Element and Bridge Team Management
A navigation audit isn't just about paper; it’s about performance. An auditor will often observe the bridge team during a period of high workload, such as a pilotage transit or a Ship-to-Ship (STS) transfer.
They are looking for effective BTM (Bridge Team Management). Are the junior officers or cadets empowered to speak up if they notice a deviation? Is the OOW distracted by administrative tasks or their mobile phone?
During your internal audit, check the Look-out arrangements. If the vessel is in restricted visibility and the logbook doesn't reflect that an additional look-out was posted, the audit will fail. Ensure that the Master/Pilot Exchange (MPX) is not just a signed paper but a verbal briefing that actually happened. Auditors now look for specific mentions of the "Point of No Return" and "Emergency Anchorage" in the MPX.
For Indian seafarers preparing for their Phase II MMD Orals in cities like Mumbai, Kolkata, or Chennai, remember that examiners often ask how you would handle a Master who ignores the passage plan. Your answer must reflect the SMS (Safety Management System) procedures for "Master’s Overriding Authority" versus "Challenge and Response."
Physical Inspection and Pyrotechnics
Finally, do a physical sweep of the bridge and bridge wings. This is the easiest part of the audit to pass, yet many fail it due to laziness.
* Check the expiry dates on Line Throwing Apparatus (LTA), Parachute Flares, and Smoke Signals.
* Ensure the Emergency Steering instructions are posted and legible.
* Verify that the Battery Room for the GMDSS is well-ventilated and the gravity of the electrolyte is within limits.
* Check the ALRS (Admiralty List of Radio Signals) and List of Lights to ensure they are updated with the latest supplements.
If you are operating in Indian waters, ensure you have the latest Indian Notices to Mariners and that your Navtex is tuned to the correct stations (like Mumbai or Chennai) to receive local coastal warnings.
