Answer
Finding out that your bunkered fuel is of more than 0.5% Sulphur (exceeding the standard MARPOL Annex VI global cap of 0.50%) , is a major regulatory emergency requiring immediate management-level intervention:
- Immediate Fuel Isolation: Order the Second Engineer to instantly isolate the non-compliant bunker tank. Do not transfer or mix this fuel with compliant fuel, as this constitutes willful dilution, which is heavily penalized under international and local maritime laws like the Indian Merchant Shipping (MS) Act, 2025.
- Switch to Compliant Fuel: Change over the fuel system to an alternative, validated compliant fuel tank (VLSFO or LSMGO) from your remaining stock on board (ROB).
- Formal Internal Notifications: Verbally brief the Master, log the exact timeline in the Engine Room Logbook, and notify the company's technical superintendent and DPA.
- Issue a Letter of Protest (LOP): Draft an immediate legal LOP to the charterers, fuel supplier, and bunkering port authorities, attaching the certified laboratory analysis report.
- File Statutory Notifications (Flag & PSC): Through the Master, send an immediate notification of non-compliance to the ship's Flag State administration and the Port State Control (PSC) of your next destination port.
- Commercial Strategy (If Compliant Stock is Insufficient): If the vessel does not have enough compliant fuel to reach the destination,
The Correct Statutory Path: MEPC.1/Circ.882 (Contingency Measures)
Instead of a FONAR, this situation is governed by MEPC.1/Circ.882 (Guidance for port State control on contingency measures for addressing non-compliant fuel oil). As Chief Engineer, the exact protocol to defend in your oral exam is:
1. Issue a Formal "Notification of Non-Compliant Fuel"
Instead of a FONAR form, the Master/Chief Engineer must send a standard regulatory notification detailing the off-spec lab results to:
- The vessel's Flag State Administration.
- The Port State Control (PSC) authority of the next destination port.
- The Bunkering Port State Administration (so they can investigate the rogue bunker supplier under MARPOL Annex VI Regulation 18).
2. Formulate an Agreed "Contingency Plan"
Under MEPC.1/Circ.882, the ship, Flag State, and the destination port must work together to agree on a solution. You must declare your current fuel status:
- If you have enough compliant alternative stock (ROB): Inform them that the off-spec tank has been isolated and you are burning compliant fuel for the remainder of the voyage.
- If you do not have enough compliant stock: You must seek permission within the Contingency Plan framework to burn the off-spec fuel strictly for the safe navigation of the vessel until the next port is reached.
3. Prepare for the Destination Port Outcome
Because of the MARPOL Carriage Ban, carrying fuel exceeding 0.50% sulfur without an exhaust gas cleaning system (EGCS/Scrubber) is illegal. Be prepared for the next port's PSC to mandate one of the following:
- Permitting the vessel to sail to a specific port where de-bunkering can be safely executed.
- Mandating immediate de-bunkering of the 0.55% fuel at your arrival port before cargo operations can be completed.
