The Port State Control Officer (PSCO) climbs the gangway at Jawaharlal Nehru Port Trust (JNPT), his clipboard already heavy with the morning’s inspection notes. After a cursory glance at the bridge wing and the fire main, he heads straight for the Ship’s Office. He doesn't ask for the SMS manual first; he asks for the Garbage Record Book (GRB). As a Chief Officer, you know the drill. You hand over the folder, but your mind races: Did the Third Officer record the incinerator ash from two nights ago? Is the estimated volume of food waste consistent with the number of crew on board? In a high-stakes inspection environment, the GRB is often the "low-hanging fruit" for a PSCO to issue a deficiency that could lead to a detention or a heavy fine from the Directorate General of Shipping (DGS).
Maintaining a flawless Garbage Record Book is not just about neat handwriting; it is about demonstrating a culture of compliance with MARPOL Annex V. Here is how you ensure your record-keeping stands up to the toughest scrutiny.
Master the Art of Accurate Entries and Categories
The most common reason for a PSC deficiency isn't a lack of equipment; it’s a lack of consistency. Under MARPOL Annex V, garbage is divided into specific categories, and misclassifying an entry is an immediate red flag.
Every entry must include the date, time, the ship’s position (latitude and longitude), and the Category of Garbage. Ensure your junior officers are intimately familiar with the distinction between Category A (Plastics) and Category J (Incinerator Ash). A frequent mistake occurs when "Operational Waste" is used as a catch-all. If you are discharging dunnage, it must be logged correctly, and if that dunnage is treated with chemicals, it might even fall under HME (Harmful to the Marine Environment) cargo residues, which requires Part II of the GRB for bulk carriers.
The Estimated Amount must be recorded in cubic metres (m³). Avoid using "bags" or "drums" as units of measurement. If the PSCO sees "4 bags of plastic" instead of "0.4 m³," you are already inviting a deeper audit. Furthermore, the "Start" and "Stop" positions for discharge at sea must be logged precisely. If the vessel's speed was less than 12 knots during a food waste discharge, or if you were within a Special Area like the Red Sea or the Mediterranean without following the stricter discharge criteria, the GRB will be the evidence used against you.
Syncing the Engine Room and Deck Logs
A savvy PSCO will cross-reference the Garbage Record Book with the Engine Room Logbook and the Bridge Movement Book. This is where many Indian seafarers get caught during MMD Mumbai or MMD Chennai oral exams and, more importantly, during actual inspections.
If the Incinerator was running from 0800 to 1200 according to the Engine Log, there must be a corresponding entry in the GRB under "Incineration." More importantly, the resulting Incinerator Ash (Category J) must be accounted for. You cannot incinerate five cubic metres of operational waste and record zero ash. The volume of ash should generally be around 1% to 10% of the load, depending on the waste type.
Similarly, ensure the GPS positions in the GRB match the Bridge Log exactly. Discrepancies of even a few miles can suggest that entries were "back-dated" or fabricated while the ship was already alongside. Always sign each completed page. The Master’s signature at the bottom of every page is a mandatory requirement; an unsigned page is an automatic deficiency.
Managing Port Reception Facilities (PRF) and Receipts
When you discharge garbage to a shore facility, the entry in the GRB is only half the battle. The Garbage Receipt provided by the contractor is the legal proof of the transaction. In many Indian ports, such as Kandla or Haldia, the quality of receipts provided by local contractors can vary.
As the officer in charge, you must ensure the receipt contains the following:
1. Date and time of reception.
2. Name of the port and the facility.
3. The specific categories of garbage collected.
4. The volume of each category in m³.
If a port facility refuses to provide a receipt in the IMO Standard Format, you must report this to the ship’s Flag State and the port authorities. Keep a copy of this report (often called a "Letter of Protest") attached to your GRB. This protects the vessel from being penalized for the port's inadequacy. Never leave a port without a signed and stamped receipt. If the PSCO sees a discharge entry in the GRB with no corresponding receipt, they will assume the garbage was illegally dumped at sea.
The "E-Waste" and "Cooking Oil" Trap
Since the 2018 amendments to MARPOL Annex V, E-waste (Category I) and Cooking Oil (Category K) have become high-priority items. Many older ships still struggle with how to record these.
E-waste includes everything from spent fluorescent tubes to old circuit boards from the bridge. These must never be incinerated or thrown overboard. They must be landed ashore. If your GRB shows zero entries for E-waste over a six-month period, a PSCO will find it suspicious. Every ship generates some form of electronic waste; ensure you have a designated bin for it and that it is logged when landed.
Cooking Oil is another trap. It must be collected in the galley and either landed ashore or burned in the incinerator (if the incinerator is certified for it). It should never be poured down the galley sink, as this leads to the grease trap, which eventually goes to the sewage holding tank or overboard, potentially causing an oily sheen. Ensure the volume of cooking oil landed matches the realistic consumption of the galley.
Indian Context: DGS Compliance and MMD Orals
For Indian officers, the Directorate General of Shipping (DGS) has issued several circulars regarding the "Swachh Sagar" initiative and the mandatory use of the DGS E-Governance portal for certain filings. When preparing for MMD Orals for Class 2 or Class 1 CoC, remember that the examiners are now focusing heavily on the Garbage Management Plan (GMP).
You must be able to explain how your specific vessel segregates waste. If you are on a Synergy Marine or Anglo Eastern managed vessel, your company-specific SMS will likely have stricter requirements than MARPOL. Always follow the more stringent rule. In Indian ports, the Indian Coast Guard also has the authority to inspect your GRB. Ensure that the INDoS numbers of the officers signing the book are clearly recorded if required by your company’s SMS, although MARPOL only strictly requires the signature and rank.
The GRB is a reflection of the ship’s discipline. A clean, accurate, and cross-referenced book tells the PSCO that the crew is professional and that the vessel is likely compliant in other, more complex areas like the OWS or the Ballast Water Treatment System.
