The Chief Engineer stands by the fuel flow meters in the engine room of a 50,000 DWT bulk carrier anchored off Jawaharlal Nehru Port Authority (JNPA). He is cross-checking the noon report data against the mass flow meter readings before the vessel begins its coastal run to Haldia. On the bridge, the Second Officer is calculating the distance over ground, ensuring every nautical mile is accounted for. This isn't just routine record-keeping; this is the front line of MARPOL Annex VI compliance. Since January 1, 2023, the stakes for fuel efficiency have moved beyond company profits and into the realm of mandatory international law through the Carbon Intensity Indicator (CII) and the Ship Energy Efficiency Management Plan (SEEMP) Part III.
For Indian seafarers working on Indian-flagged vessels or international tonnage, understanding the mechanics of SEEMP Part III is no longer optional. It is a critical competency required for MMD oral exams and, more importantly, for the daily operational survival of the ship.
Understanding the Regulatory Framework of SEEMP Part III
The International Maritime Organization (IMO) introduced SEEMP Part III as a mandatory requirement under MARPOL Annex VI for all ships of 5,000 gross tonnage (GT) and above engaged in international voyages. While SEEMP Part I focused on corporate-level energy management and Part II dealt with the Data Collection System (DCS), Part III is a "living document" that outlines exactly how a ship will achieve its required CII rating.
The CII rating is an operational efficiency metric that measures how carbon-intensively a ship carries goods or passengers. It is expressed in grams of CO2 emitted per cargo-carrying capacity and nautical mile. Based on this, every ship is given an annual rating ranging from A (Major superior) to E (Inferior).
For an Indian officer, the technicality lies in the Required Annual Operational CII. This target becomes progressively more stringent every year until 2030. If your vessel receives a 'D' rating for three consecutive years or an 'E' rating for a single year, you are legally mandated to develop a Plan of Corrective Actions to achieve the required 'C' rating or higher. This plan must be integrated into the SEEMP Part III and verified by the Recognized Organization (RO)—which, for most Indian flag vessels, is the Indian Register of Shipping (IRS).
Practical Data Collection and the Role of the Noon Report
Accuracy in the engine room and bridge logs is the foundation of SEEMP Part III compliance. The CII rating is calculated based on the data submitted through the IMO DCS. If the data is flawed, the rating is flawed, and the vessel could face commercial and regulatory sanctions.
Onboard an Indian vessel, the responsibility often falls on the Second Engineer and the Second Officer. You must ensure that every drop of fuel—whether it is Very Low Sulphur Fuel Oil (VLSFO), High Sulphur Fuel Oil (HSFO) used with a scrubber, or Marine Gas Oil (MGO)—is recorded accurately. The Bunker Delivery Notes (BDNs) must match the tank soundings and the flow meter readings.
One common pitfall is the failure to account for "corrections" allowed under the CII framework. The IMO allows for certain fuel consumptions to be deducted from the total before calculating the rating. This includes fuel used for cargo heating, tank cleaning, or during periods of ship-to-ship (STS) transfers. As an officer, you must maintain a separate, verifiable log for these consumptions. If you are discharging at Kandla and running high-capacity hydraulic pumps or boilers for cargo heating, that fuel should not penalize your vessel’s CII rating. Without precise logging, the vessel appears less efficient than it actually is.
Developing and Implementing the SEEMP Part III Action Plan
The SEEMP Part III is not a document that should sit in a binder in the Master’s office; it is an operational roadmap. It must contain a description of the methodology used to calculate the ship’s Attained Annual Operational CII and the process for reporting this data to the Directorate General of Shipping (DGS) or the IRS.
The core of the document is the Implementation Plan. This section lists the specific measures the ship will take to stay within its target rating. These measures typically include:
1. Speed Optimization: This is the most effective way to improve a CII rating. Reducing speed by even one knot can significantly lower fuel consumption and CO2 emissions.
2. Weather Routing: Utilizing currents and avoiding heavy weather to maintain a steady speed-over-ground without increasing engine load.
3. Hull and Propeller Maintenance: Scheduling regular underwater inspections and cleanings, especially after long stays in tropical waters like the Bay of Bengal, where biofouling is rapid.
4. Trim and Draft Optimization: Ensuring the vessel is at its most efficient hydrodynamic profile for the given cargo load.
For the Chief Officer, this means coordinating with the charterers and the engine room. If the charterer demands a speed that will push the vessel into a 'D' or 'E' rating, the Master must refer to the SEEMP Part III and the company’s environmental policy to negotiate a more sustainable speed.
The Indian Context: DGS, IRS, and MMD Compliance
For vessels flying the Indian flag, the Directorate General of Shipping (DGS) oversees the enforcement of MARPOL Annex VI. The DGS has delegated the verification of SEEMP Part III to Recognized Organizations like the IRS.
The process begins with the vessel’s management company submitting the SEEMP Part III to the IRS for approval. Once approved, the vessel is issued a Confirmation of Compliance (CoC). This document must be kept on board and is subject to inspection during Port State Control (PSC) at international ports or Flag State Inspections (FSI) at Indian ports like Mumbai or Chennai.
During MMD (Mercantile Marine Department) exams for Class 1 or Class 2, surveyors often ask about the "Statement of Compliance." It is vital to distinguish between the CoC (for the plan) and the Statement of Compliance (SoC) for fuel oil consumption, which is issued annually after the data for the previous year has been verified.
Furthermore, Indian seafarers must be aware of the DGS e-governance portal. While the company handles the bulk of the filing, the Master is responsible for ensuring that the Oil Record Book (ORB) and the MARPOL logs are consistent with the digital data being uploaded. Discrepancies between the physical logs and the digital CII reporting can lead to severe deficiencies during an audit at the MMD Mumbai office or during a vetting inspection.
Operational Strategies for Junior Officers and Ratings
While senior officers handle the planning, junior officers and ratings are the ones who execute the SEEMP Part III measures. For a Fourth Engineer or a Junior Engineer, this means ensuring that the auxiliary machinery is running at peak efficiency. Are the air compressors leaking? Is the boiler burner tuned correctly? Even small inefficiencies contribute to the total fuel consumption, which impacts the CII.
For the bridge team, it involves meticulous record-keeping of the "distance traveled" and "hours underway." In the CII formula, distance is the denominator. If the distance is under-reported due to poor logging of drift or deviations, the carbon intensity appears higher.
In my experience, the most successful ships are those where the SEEMP Part III is discussed during the monthly safety and environmental meetings. Instead of just reading out a circular, the Chief Engineer should show the crew the current CII trajectory. "Team, we are currently at a high 'C'. If we optimize our generator usage in port, we can hit a 'B'." This level of transparency turns a bureaucratic requirement into a collective goal.
