The Port State Control (PSC) officer boards the vessel at Mundra Port, his eyes scanning the deck for any signs of non-compliance before he even reaches the ship’s office. After a brief introduction and a quick look at the certificates, he asks for the one document that causes more deficiencies than almost any other: the Garbage Record Book (GRB). As the Second Officer or Chief Officer, you hand it over, knowing that even a single missing signature, a wrong coordinate, or a slight discrepancy in estimated weight can lead to a formal observation or, worse, a detention. The inspector flips through the pages, cross-referencing the entries with the Bridge Logbook and the Engine Room Logbook. This is the moment where meticulous record-keeping pays off or where a career-stalling mistake is uncovered.
Maintaining the Garbage Record Book is not just a clerical task; it is a critical component of MARPOL Annex V compliance. For Indian seafarers working on high-standard fleets like Synergy Marine or Anglo Eastern, the expectation is zero-defect documentation.
Understanding the Structure: Part I and Part II
Since the 2018 amendments to MARPOL Annex V, the Garbage Record Book has been divided into two parts. Understanding the distinction is the first step toward error-free reporting.
Part I is applicable to all ships. This section covers all garbage types except cargo residues. It includes categories such as Plastics (Category A), Food Wastes (Category B), Domestic Wastes (Category C), Cooking Oil (Category D), Incinerator Ashes (Category E), Operational Wastes (Category F), Animal Carcass(es) (Category G), Fishing Gear (Category H), and E-waste (Category I).
Part II is specific to ships carrying solid bulk cargoes. This section records the discharge of Cargo Residues (Category J and K). Category J covers residues that are not harmful to the marine environment (Non-HME), while Category K covers residues that are harmful (HME).
When you are filling out these sections, remember that every entry must be made in English, French, or Spanish, though English is the universal standard for international trade. Each completed page must be signed by the Master of the ship. This is a common point of failure—if the Master’s signature is missing from a page that was completed three days ago, the PSC inspector will mark it as a deficiency.
Precise Entries: Avoiding the "Estimated Weight" Trap
One of the most frequent questions during MMD Oral Exams in cities like Mumbai or Chennai revolves around how to estimate the weight of garbage. PSC inspectors look for consistency. If your vessel consistently records exactly "0.5 m³" for food waste every single day, it raises a red flag. It looks fabricated.
When recording a discharge, you must provide the date and time of the operation, the ship’s position (latitude and longitude), and the estimated amount discharged or incinerated in cubic meters (m³).
For Food Waste (Category B), the rules change based on your location. If you are outside a Special Area, discharge is permitted at more than 12 nautical miles from the nearest land while the ship is en route. If the food waste has been passed through a comminuter (able to pass through a screen with openings no greater than 25mm), the distance is reduced to 3 nautical miles.
In the Garbage Record Book, you must clearly state the position. If you are discharging at 13 nautical miles, ensure your coordinates match the GPS log at that exact time. Discrepancies between the GRB and the Bridge Logbook are a "low-hanging fruit" for inspectors. If the logbook says you were at 10 nautical miles but the GRB says 13, you are in violation of MARPOL Annex V.
Handling Shore Disposal and Incineration
Discharging garbage to a shore reception facility is the safest way to ensure compliance, but it requires the most paperwork. Every time you hand over garbage to a barge or a truck—whether it’s in Kolkata, Singapore, or Rotterdam—you must obtain a Garbage Receipts or a Waste Delivery Receipt (WDR).
The entry in the GRB must match the receipt exactly. If the receipt from the vendor at Kandla Port says 4.0 m³ of plastic and domestic waste, do not write 3.5 m³ in the book. You must also record the name of the facility and the date of the transfer. These receipts must be kept on board for at least two years.
For Incineration (Category E), you must record the start and stop times of the incinerator, the position of the ship at both times, and the estimated amount of garbage incinerated. Remember, Incinerator Ash must never be discharged into the sea. It must be recorded as a transfer to a shore facility. A common mistake is forgetting to record the disposal of the ash itself; if you incinerate 5.0 m³ of waste, the inspector will eventually want to see where the resulting ash went.
The Single-Use Plastic (SUP) and Indian Context
The Directorate General of Shipping (DGS) has been particularly stringent regarding the ban on Single-Use Plastics (SUP) on Indian-flagged vessels and foreign vessels in Indian waters. As an Indian seafarer, you must be aware of DGS Order No. 05 of 2019 and subsequent circulars.
When a PSC officer boards in an Indian port, they may check your Garbage Management Plan (GMP) to see how you are managing the phase-out of SUPs. Ensure that your GRB reflects this. For example, if you have received stores in Chennai, and those stores came with excessive plastic packaging, your records should show how that plastic was segregated and stored for shore disposal.
If there is an Accidental Loss of garbage—for example, if a collection bin is washed overboard in heavy weather—this must be recorded in the GRB with a detailed explanation of the circumstances and the precautions taken to prevent a recurrence. This is a "Category L" entry in some modern electronic formats, though officially it is recorded under the "Exceptional Discharge" section of the manual book.
PSC Inspection Tips: The Final Walkthrough
Before arrival at any port, the Chief Officer should conduct a "pre-PSC" audit of the Garbage Record Book. Check for the following:
1. No Gaps: Every day that garbage was handled must have an entry. If no garbage was discharged or incinerated over a long period (rare but possible), some companies require a "nil" entry to show the book is being maintained.
2. Signatures: Ensure the officer in charge signs each entry at the time of the operation, and the Master signs every page.
3. Correct Categories: Ensure that Cooking Oil is never mixed with Food Waste. Cooking oil is Category D and must be handled separately (often landed ashore or incinerated).
4. Special Areas: Be hyper-aware if you have been sailing in the Mediterranean, the Red Sea, or the Persian Gulf. The discharge rules in these Special Areas are much stricter (generally zero discharge for almost everything except food waste under specific conditions).
5. Cleanliness: A physical book that is stained with coffee or grease suggests a lack of professional care. Keep the book in a dedicated folder in the ship’s office.
A well-maintained Garbage Record Book tells the inspector that the vessel is run by a disciplined crew. It is often the "litmus test" for the rest of the inspection. If the GRB is perfect, the inspector is less likely to spend hours digging through your Oil Record Book or testing your OWS.
