The 0400-0800 watch is usually the quietest time on the bridge, but as the sun begins to rise over the horizon near the Jawaharlal Nehru Port Trust (JNPT), the Master walks onto the bridge with a stack of checklists. He doesn't look at the radar; he looks straight at the ECDIS and then at you. "The internal auditor is boarding at the pilot station," he says. "He’s focusing on the navigation department this time." For a Second Officer, this is the moment where your months of meticulous record-keeping and passage planning are put to the ultimate test. A navigation audit isn't just a check on the ship’s equipment; it is a direct assessment of your professional competence and your ability to maintain shipboard safety under scrutiny.
Mastering the Passage Plan: Beyond the Software
The Passage Plan (PP) is the primary document any auditor—whether internal, SIRE 2.0, or RightShip—will scrutinize. As the Second Officer, you are the designated Navigation Officer, and the PP is your signature. It must be Berth-to-Berth. An auditor will immediately look for gaps between the pilot station and the actual berth. If your plan ends at the "Alpha" anchorage but the ship is alongside, you have already failed the first check.
Ensure that your Appraisal includes all relevant Provisional and Preliminary (P&P) Notices and Temporary and Preliminary (T&P) Notices. In the Indian context, ensure you have checked the Nautical Adviser circulars if applicable to your specific trade route. Your Under Keel Clearance (UKC) calculations must account for Squat, increase in draft due to Heel, and the specific Safety Contour settings on your ECDIS.
When setting the Safety Depth, remember the formula: Safety Depth = Draft + Static UKC + Squat + Sea Margin - Tides. If the auditor asks why your Safety Contour is set to 10 meters when your draft is 8 meters, you must be able to justify it using your company’s Safety Management System (SMS) guidelines. Companies like Synergy Marine or Anglo Eastern have very specific SMS requirements for these settings; knowing them by heart shows the auditor you are aligned with the company’s safety culture.
ECDIS Compliance and Electronic Record Keeping
In 2025, paper charts are almost a relic of the past, making ECDIS the centerpiece of any navigation audit. The auditor will check your ENC (Electronic Navigational Charts) update status. You must demonstrate that your charts are updated to the latest Notice to Mariners (NtM). Check the Update Log and ensure the IHO S-52 Presentation Library is the current version (4.0 or later).
A common trap for Second Officers is the Route Check function. An auditor will pick a random leg of your current voyage and ask you to run the route check. If there are 50 "Safety Contour Crossed" or "Navigational Hazard" alarms that you haven't individually reviewed and cleared, it indicates a lack of monitoring. You must show documented evidence that every alarm triggered by the ECDIS during the planning stage has been assessed.
Furthermore, ensure your User Maps or Manual Updates are clean. If there is a Navtex warning about a sunken trawler off the coast of Visakhapatnam, it should be plotted manually on the ECDIS if it isn't already in the latest ENC update. Also, verify the Sensor Input status; if your Positioning System (GPS) has a high HDOP (Horizontal Dilution of Precision), you should know how to switch to the secondary source or use Radar Positioning (PI indexing) to verify your fix.
Bridge Equipment and GMDSS Readiness
While the passage plan is the "brain" of the audit, the bridge equipment is the "body." You are responsible for the maintenance and testing of all navigational aids. The Magnetic Compass is a favorite for auditors. They will check your Compass Error Log against the Deck Log Book. If the error hasn't been taken once every watch, or at every large alteration of course, it’s a major non-conformity. Ensure the Deviation Card is valid and that the lifeboats' compasses have been checked during drills.
For GMDSS equipment, the auditor will look at the GMDSS Log Book. You must have records of:
* Daily Tests: Battery voltages and printer checks.
* Weekly Tests: DSC internal loopback tests and handheld VHF checks.
* Monthly Tests: EPIRB (Emergency Position Indicating Radio Beacon) and SART (Search and Rescue Transponder) physical inspections and self-tests.
Check the expiry dates on the HRU (Hydrostatic Release Unit) for the EPIRB and the batteries for the GMDSS handheld radios. If you are preparing for an MMD Mumbai or MMD Kolkata survey, these details are non-negotiable. The AIS (Automatic Identification System) data must also be current—ensure the destination, ETA, and current draft are updated as soon as the "Standby" is called.
The Human Element: Logs, Checklists, and Standing Orders
An audit often reveals more about the bridge team’s discipline than the ship’s hardware. The Deck Log Book must be a clean, chronological narrative of the voyage. Avoid excessive use of correction fluid; if a mistake is made, cross it out with a single line, initial it, and write the correct entry.
The auditor will verify if the Master’s Standing Orders and Night Orders are signed by all OOWs. This isn't just a formality; it proves that you have read and understood the Master’s expectations for the watch. During the audit, you might be asked: "What are the Master’s calling-in points?" You should be able to point to the posted orders immediately.
Familiarize yourself with the Bridge Procedures Guide (BPG). If the auditor asks about your actions during "Restricted Visibility," don't just say "I'll call the Master." Mention the specific steps: inform the engine room, start manual steering, turn on navigation lights, begin fog signals, and increase the bridge lookout. Showing that you follow a systematic Checklist approach (as mandated by DGS and international standards) gives the auditor confidence in your shipboard safety management.
Preparing for the Auditor’s Interview
The final stage of the audit is often a face-to-face discussion. The auditor isn't looking for a robot; they are looking for a thinking officer. When asked a question, be direct. If you don't know the answer, don't guess. Say, "I will refer to the SMS Manual or the Manufacturer’s Manual to give you the exact answer." This shows you know where to find information, which is more important than memorizing every technical specification.
Ensure your INDoS number and CoC (Certificate of Competency) details are updated in the DGS e-governance portal, as some auditors now verify the validity of officer certification online during the audit process. Keep your CDC and training certificates (like ECDIS Type Specific) organized in a clear folder. If you’ve recently completed a course or a renewal at an MMD center, ensure the physical copies or verified digital versions are ready for inspection.
A successful navigation audit is the result of 90% preparation and 10% performance. By treating every watch as if it were an audit, the actual inspection becomes just another day on the bridge.
