Port State Control and Bunkering Compliance in Nigeria
Port State Control is one of the most consequential realities of modern maritime operations. A single deficiency notice can delay a vessel by hours. A detention can cost days, threaten charter commitments, and trigger a cascade of financial and reputational consequences that outlast the original inspection. And yet, a significant number of vessel operators still treat bunkering compliance in Nigeria as a secondary concern, separate from the broader PSC risk picture.
It is not. The fuel a vessel takes on in Nigerian waters, the documentation that accompanies that fuel, and the supplier responsible for delivering it are all directly relevant to how a PSC inspection plays out.
What Port State Control Is and How It Works in Nigeria
Port State Control is the system by which a coastal country’s maritime authority inspects foreign-flagged vessels visiting its ports to verify compliance with international maritime conventions. The core conventions being checked are SOLAS (Safety of Life at Sea), MARPOL (Marine Pollution), STCW (Standards of Training, Certification and Watchkeeping), MLC 2006 (Maritime Labour Convention), and the Load Line Convention.
According to the Port State Control Inspection 2026 guide, PSC is organised through nine regional Memoranda of Understanding (MoUs). Nigeria operates under the Abuja MoU, which covers West and Central Africa. Detention data is shared between all regions, so a detention recorded in Nigerian waters is visible to inspectors worldwide.
Nigeria takes PSC seriously. NIMASA, the Nigerian Maritime Administration and Safety Agency, is the body responsible for conducting PSC inspections in Nigerian ports and has consistently set the inspection benchmark for other African countries under the Abuja MoU. Vessels are selected for inspection based on a risk profile that considers the ship’s age, flag state performance, classification society, company detention history, and time since the last inspection.
Where Bunkering Fits Into PSC Risk
MARPOL Annex VI is the international convention that directly governs the sulphur content and emissions-related properties of marine fuel. Under MARPOL Annex VI, vessels are required to use fuel that meets the applicable sulphur limit for the waters they are operating in: 0.50% globally since January 2020, or 0.10% in designated Emission Control Areas.
PSC inspectors can and do check MARPOL compliance during inspections. This includes reviewing the vessel’s oil record book, checking BDNs from recent bunkering operations, and in some cases requesting fuel samples for laboratory testing. A BDN that does not comply with MARPOL requirements, or one that cannot be produced, is a deficiency that can escalate quickly during an inspection.
The relevance of bunkering compliance in Nigeria is therefore direct: every stem taken on in Nigerian waters generates documentation that may be reviewed by a PSC inspector, whether in Nigeria itself or in a subsequent port of call anywhere in the world.
The BDN: Your First Line of Compliance
The Bunker Delivery Note is the foundational document of fuel compliance. Under MARPOL Annex VI, BDNs must be retained on board for three years from the date of delivery and must contain specific information: the vessel’s name and IMO number, the port and date of bunkering, the supplier’s name, the type and quantity of fuel delivered, the sulphur content, and the supplier’s declaration that the fuel meets the applicable standard.
In Nigeria, the quality of BDN documentation varies between suppliers. Reputable, NMDPRA-licensed suppliers who operate to international standards will provide BDNs that meet full MARPOL requirements. Less regulated suppliers may produce documents that are incomplete, inconsistent, or that do not meet the technical specifications that a PSC inspector would expect to see.
For vessel operators, this means that supplier selection is a compliance decision, not just a commercial one. Accepting fuel from a supplier who cannot provide a MARPOL-compliant BDN is not a minor administrative shortcut. It is a compliance failure that can be cited during a PSC inspection months later.
Fuel Quality and Off-Spec Risk
Off-spec fuel creates both operational and compliance risk. Operationally, fuel that falls outside specification can cause machinery damage, filter blockages, combustion problems, and unplanned maintenance. From a compliance standpoint, fuel that does not meet the applicable sulphur standard is a direct MARPOL violation.
Industry data from mid-2026 shows that bunker-related claims rose sharply in the first half of the year, with a significant increase in cases involving fuel quality disputes that carry compliance implications for the receiving vessel.
The safeguard is independent sampling. When bunkering in Nigeria, vessel masters should ensure that representative fuel samples are taken at the point of delivery in accordance with the standard MARPOL sampling procedure. These samples are the vessel’s primary defence in the event of a quality dispute or a PSC inquiry about fuel compliance.
Supplier Credentials and Their PSC Relevance
A PSC inspector reviewing a vessel’s bunkering records may consider not only the BDN but also who supplied the fuel and whether that supplier is authorised to operate in the relevant jurisdiction. Bunkering from a supplier who is not licensed by the NMDPRA, or who cannot produce documentation confirming their regulatory standing, creates an additional layer of risk for the vessel operator.
Requesting a copy of the supplier’s current NMDPRA operating licence before confirming a stem is a reasonable due diligence step. Checking for ISO 9001:2015 certification adds further assurance that the supplier operates a quality management system that reduces off-spec risk.

The Abuja MoU and What It Means for Nigerian Port Calls
The Abuja MoU covers 27 member states across West and Central Africa. Under this regime, PSC inspection records, detentions, and deficiency reports are shared among member states and linked to global systems that inspectors in other regions can access.
For vessel operators, the implication is that a bunkering-related deficiency found during a PSC inspection in Nigeria does not stay in Nigeria. It travels with the vessel’s inspection record. A BDN discrepancy identified in Lagos may be the trigger for a more detailed inspection in Lomé, Abidjan, or a European port on the vessel’s next voyage.
Practical Steps for Operators Bunkering in Nigeria
The compliance checklist for bunkering compliance in Nigeria is not complicated. But it requires consistent application.
Verify supplier licensing before confirming a stem. Ask for the NMDPRA licence number and confirm it is current. Check whether the supplier holds ISO 9001:2015 certification.
Review the BDN before signing it. Confirm that all required fields are complete and accurate, including the sulphur content declaration. Do not sign a BDN that contains errors or omissions.
Take and retain fuel samples. Use the standard MARPOL drip sampling method during delivery. Retain samples for three years alongside the BDN.
Record the bunkering operation in the oil record book promptly and accurately. Raise quality concerns immediately before the barge departs, and note any concern in writing to the supplier.
