The 0400-0800 watch is usually the quietest time on the bridge, but today the atmosphere is different. The vessel is twelve miles off Mundra Port, and the Master has just informed you that a company internal auditor—or worse, a SIRE inspector—will be boarding with the pilot. As the Second Officer and designated Navigation Officer, the bridge is your domain. Every corrected chart, every entry in the GMDSS Logbook, and every setting on the ECDIS is about to be scrutinized. An audit isn't just a test of the ship’s equipment; it is a direct evaluation of your professional competence and attention to detail.
In the modern maritime industry, especially within high-standard vetting regimes, the "Navigation Audit" has become a rigorous process. For an Indian officer, the stakes are high. Your performance reflects not only on the ship’s safety record but also on your reputation as you look toward your Chief Mate or Master (FG) orals at MMD Mumbai or MMD Chennai.
Mastering the Passage Plan: Berth-to-Berth Compliance
The Passage Plan is the first thing any auditor will pull. It is the blueprint of the voyage, and if it’s flawed, the audit is lost before it begins. As the 2/O, you must ensure the plan is truly Berth-to-Berth. A common observation is a plan that starts at the pilot station and ends at the next pilot station. This is a major non-conformity.
Your plan must include detailed Abort Points and Point of No Return (PNR), especially when navigating restricted waters like the Hooghly River or the Gulf of Kutch. Auditors look for specific Safety Contours and Safety Depths calculated based on the vessel’s current static and dynamic Under Keel Clearance (UKC) policy.
Ensure that the CATZOC (Category Zone of Confidence) is factored into your safety margins. If the chart data is ZOC U (Unassessed) or ZOC D, you must increase your safety depth settings. Furthermore, verify that all Temporary and Preliminary (T&P) Notices are manually plotted on the ECDIS. Many 2/Os rely solely on the weekly update disc, but manual T&Ps are a frequent "low-hanging fruit" for auditors.
ECDIS Management and Sensor Integrity
In 2025, the transition to "Paperless Navigation" is complete for most of the fleet. However, the ECDIS is only as good as the data it receives. During an audit, you will likely be asked to demonstrate the Route Check function. If there are 500 "Safety Contour" or "Prohibited Area" alarms that you’ve ignored, you will fail the audit. You must be able to justify why certain alarms are ignored or how they are being managed.
Check your sensor inputs. Ensure the Positioning System (GPS/GNSS), Gyro, and Log are all feeding correctly into both ECDIS units. An auditor might ask you to demonstrate what happens if the primary GPS fails. Can you switch to the secondary? Do you know how to perform Dead Reckoning (DR) or use Radar Overlay for position verification?
Another critical area is the Safety Settings. The Safety Contour must be set according to the Master’s Standing Orders. If the Master’s orders say 12 meters and your ECDIS is set to 10 meters, it shows a lack of Bridge Team Management (BTM). Always ensure the Look-ahead (Anti-collision) settings are appropriate for the current visibility and traffic density.
The Paper Trail: Logs, Certificates, and Maintenance
The "Paper Trail" is where most 2/Os get caught. Even in a digital age, the GMDSS Logbook, Compass Error Book, and Chronometer Log remain vital legal documents.
1. GMDSS Log: Ensure all daily, weekly, and monthly tests of the DSC, Reserve Source of Energy (Batteries), and EPIRB/SART are recorded. If you are in an Indian port, ensure your Radio License is valid and displayed.
2. Compass Error Book: You should be taking a compass error on every watch, or at least once every major course alteration. If the auditor sees a week of "Cloudy" entries while the vessel was transiting the sunny Indian Ocean, they will doubt your integrity.
3. Charts and Publications: Verify that your ALRS, ATT, and Sailing Directions are updated to the latest Notice to Mariners (NTM). For Indian officers, ensure you have the latest DGS Circulars relevant to navigation and safety equipment.
4. Bridge Equipment Maintenance: The Annual Performance Test (APT) for the VDR and the Radio Survey certificates must be within their validity dates. Check the Battery Expiry Dates on your GMDSS handheld VHFs and SARTs.
The Human Element: Watchkeeping and Communication
An auditor isn't just looking at screens; they are watching you. They will observe how you interact with the Rating on Watch (AB/OS) and how you handle VHF communications.
When the auditor asks a question, be direct. If you don't know the answer, know exactly where to find it in the Bridge Procedures Manual (BPM) or the Safety Management System (SMS). Never guess. For example, if asked about the procedure for "Navigation in Restricted Visibility," don't just give a vague answer—refer to COLREG Rule 19 and your ship-specific SMS requirements for calling the Master and posting a lookout.
Demonstrate a clear understanding of Master’s Standing Orders and Night Orders. These should be signed by all OOWs. If you are transiting a high-traffic area like the Singapore Strait or approaching JNPT, the auditor will look for evidence that the bridge was adequately manned according to the vessel’s Minimum Safe Manning Document.
Finally, ensure your INDoS and CDC are ready for inspection. While these are personal documents, a missing or expired STCW endorsement (like your ECDIS Type-Specific Training) can lead to a vessel detention.
