IMO 2026 Amendments, a Nigerian Compliance Checklist for Shipowners, Ports and P&I Clubs

Last updated: 2 June 2026

A raft of amendments to the International Maritime Organization’s core conventions, SOLAS, MARPOL, STCW and the Maritime Labour Convention, entered into force on 1 January 2026, creating immediate compliance obligations for every vessel trading in or through Nigerian waters. For operators subject to IMO amendments in Nigeria, the challenge is not simply understanding the new rules but mapping them to domestic implementation by the Nigerian Maritime Administration and Safety Agency (NIMASA), the Federal Ministry of Marine and Blue Economy, and the parallel legislative reforms now moving through the National Assembly.

This article provides a step-by-step shipowner compliance checklist, a port and terminal action plan, and P&I club guidance, all calibrated to the Nigerian regulatory environment, including the Nigerian Ports and Harbours Authority reform under the proposed NPERA and the Maritime Zones Bill currently before lawmakers.

Operators who delay risk Port State Control (PSC) detentions, coverage disputes with insurers, and regulatory penalties that are becoming progressively harder to reverse once a vessel’s detention record is flagged in the Abuja MoU database. The sections below provide a practical 30/60/90-day roadmap, sample clauses for charterparty redlines, and downloadable templates that compliance teams can deploy immediately.

What Changed at the IMO in 2026, Quick Instrument Map

The IMO confirmed that the amendments taking effect from 1 January 2026 constitute one of the most significant packages of regulatory changes in recent years, touching safety of life at sea, marine environmental protection, seafarer welfare and operational reporting. Below is a concise instrument-by-instrument summary of the changes most relevant to Nigerian operators.

SOLAS Amendments, Lifting Appliances, Certificates and Survey Timing

The headline SOLAS amendment for 2026 is the revision to Regulation II-1/3-13, which introduces enhanced requirements for lifting appliances and winches on board ships. Vessels must now hold valid test and examination certificates for all cranes, derricks and associated gear, verified at prescribed intervals aligned with the ship’s survey cycle. For existing ships, compliance is required no later than the first renewal survey on or after 1 January 2026.

Practical implications for Nigerian-flagged or Nigeria-trading vessels include:

• Certificate audit. Masters and designated persons ashore (DPAs) must verify that every lifting appliance certificate on board matches the updated SOLAS format and has been issued or endorsed by a recognised organisation.
• Survey scheduling. Shipowners should confirm the date of their next renewal or intermediate survey with their classification society and ensure that any outstanding lifting appliance inspections are completed before that date.
• Safety Management System (SMS) update. The vessel’s SMS must reference the new regulation and include procedures for periodic testing, record-keeping and deficiency reporting for lifting gear.

MARPOL Amendments, Tanker Operations and Environmental Compliance

The 2026 MARPOL amendments span multiple annexes. Key changes include revised discharge and reporting requirements under Annex I (oil), updates to cargo residue and tank-washing procedures under Annex II (noxious liquid substances), and refined provisions under Annex VI relating to energy-efficiency measures and carbon-intensity indicators. For tankers calling at Nigerian oil export terminals, Bonny, Brass, Forcados and Qua Iboe, the operational impact is direct.

Nigerian port operators and ship agents should note:

• Oil Record Book entries. Bridge and engine-room teams must ensure that all discharge entries comply with the revised Annex I format.
• Waste reception coordination. Terminals must confirm that their waste reception facilities can process the categories of residue now subject to stricter discharge controls under the amended annexes.
• CII record-keeping. Ships must maintain updated records demonstrating compliance with carbon-intensity indicator (CII) operational thresholds, which NIMASA inspectors may request during PSC inspections.

STCW, MLC and Other Instruments, Crew Welfare, Training and Container Reporting

Amendments to the STCW Convention introduce mandatory training requirements addressing harassment and bullying at sea, reflecting a broader industry push towards improved seafarer welfare. The Maritime Labour Convention (MLC) amendments reinforce these obligations by requiring that shipowners demonstrate documented anti-harassment policies and training logs during flag-state and port-state inspections.

A separate but significant change involves the mandatory reporting of containers lost at sea, adopted through MSC resolution. Masters must now file electronic reports in the prescribed format whenever containers are lost overboard, and coastal states, including Nigeria, are expected to designate a receiving authority for these reports.

For compliance officers, the actionable items are:

• Crew training records. Verify that all seafarers have completed harassment and bullying awareness training and that certificates are current.
• Company policy update. Amend the company’s onboard policy documents to reflect the anti-harassment requirements and ensure copies are posted in crew common areas.
• Lost container reporting protocol. Establish an electronic reporting template on the bridge and identify the NIMASA contact point for container-loss notifications.

How IMO Amendments Become Nigerian Maritime Law, Adoption Route and Timeline

Understanding the domestic adoption pathway is essential for any operator assessing when and how IMO 2026 amendments will be enforced in Nigeria. Nigerian maritime law draws its authority from a combination of international treaty accession, federal legislation (principally the Merchant Shipping Act and the NIMASA Act), and subsidiary instruments issued by the Minister or NIMASA.

International Accession and NIMASA’s Role

Nigeria has been proactive in depositing accession instruments at the IMO. NIMASA has publicly confirmed that the Federal Government has deposited accession instruments for several IMO conventions and their protocols, a step that signals intent to be bound by the latest amendments. The IMO Secretary-General has commended Nigeria for its implementation track record, a diplomatic signal that creates practical expectations for enforcement. Once an amendment enters into force internationally through the IMO’s tacit acceptance procedure, Nigeria is bound unless it has lodged an objection, which it has not done for the 2026 package.

Domestic Legislative and Executive Steps

Even where an amendment is internationally binding, its domestic enforcement typically follows a sequence that compliance teams should track:

• Federal Gazette publication. The Federal Ministry of Marine and Blue Economy may publish a notice confirming the amendments’ applicability in Nigeria. Monitor the Gazette for these notices.
• NIMASA circulars and Marine Notices. NIMASA issues Marine Notices to the industry specifying compliance expectations, deadlines and inspection guidance. These are the primary operational documents for day-to-day compliance.
• Subsidiary regulations. Where the Merchant Shipping Act requires specific regulations to give effect to an amendment (for example, new certificate forms), NIMASA drafts subsidiary instruments for ministerial approval.
• Internal compliance cut-off. Industry observers expect that NIMASA will issue Marine Notices for the 2026 amendments within the first half of 2026. Operators should not wait: international entry into force means PSC inspectors can already cite deficiencies against the amended standards.

Compliance teams should designate a regulatory watch officer to monitor NIMASA’s website and the Federal Gazette. A sample internal memo requesting confirmation from NIMASA on specific amendment implementation timelines is included in the templates section below. Operators familiar with Nigeria’s regulatory compliance approach in the oil and gas lifecycle will recognise a similar pattern of phased domestic adoption.

Immediate Shipowner Compliance Checklist, Who Must Act and When

The following 30/60/90-day checklist breaks down priority actions by entity type. It is designed to be printed, assigned to responsible officers and tracked to completion.

Shipowner and Ship Manager Checklist

Within 30 days:

• Conduct a fleet-wide audit of all lifting appliance certificates against SOLAS Regulation II-1/3-13 requirements. Flag any certificates expiring before the next renewal survey.
• Confirm with classification society the date of the next renewal or intermediate survey for each vessel and request a gap analysis against the 2026 amendments.
• Issue a fleet circular to all masters instructing immediate review of Oil Record Book entry formats under revised MARPOL Annex I.
• Verify that every seafarer’s training record includes documented harassment and bullying awareness training compliant with the STCW amendments.

Within 60 days:

• Update the Safety Management System (SMS) to incorporate references to the amended SOLAS, MARPOL, STCW and MLC provisions. Submit the updated SMS to the company’s Document of Compliance (DoC) auditor.
• Establish an electronic lost-container reporting template on the bridge of every vessel and distribute the NIMASA contact point for notifications.
• Review and update the company’s anti-harassment policy. Ensure that copies are distributed to all vessels and that crew acknowledgement signatures are collected.
• Instruct the company’s P&I correspondent to confirm that existing cover responds to the amended regulatory framework, particularly for lifting appliance incidents and pollution liabilities.

Within 90 days:

• Complete any outstanding lifting appliance tests, load tests and certification renewals. Retain copies of all test reports on board and ashore.
• Conduct a tabletop exercise simulating a PSC inspection focused on the 2026 amendments. Identify and close any remaining gaps.
• File a compliance status report with the company’s board or management committee, documenting all steps taken and any residual risks requiring escalation.

Port and Terminal Operator Checklist

Within 30 days:

• Audit all port-side crane and lifting equipment certificates to ensure they meet the updated SOLAS standard. Coordinate with the terminal’s classification or inspection body.
• Confirm that waste reception facilities can handle the revised categories of residues under the MARPOL Annex II amendments. Contact NIMASA if facility upgrades are needed.
• Designate a local contact point for lost-container reports from vessels and ensure the contact details are communicated to shipping agents and NIMASA.

Within 60 days:

• Update berth contingency and emergency response plans to reference the 2026 amendments, particularly for pollution response and container salvage.
• Coordinate with local content compliance teams to ensure that any new equipment procurement or service contracts triggered by the amendments satisfy Nigerian Content Development and Monitoring Board (NCDMB) requirements.

P&I Club Priorities

• Coverage review. Clubs should circulate a member advisory confirming that Rule changes triggered by the 2026 amendments, particularly around lifting appliance liabilities and pollution, are addressed by existing terms or require endorsement.
• Claims handling update. Update claims-handling protocols for container-loss incidents, which now carry mandatory reporting obligations that may generate documentary records usable in subsequent litigation or arbitration.
• Vetting guidance. Revise vetting questionnaires to include specific questions on 2026 amendment compliance, lifting appliance certificates, CII records, and crew training documentation, for both owned and chartered tonnage.

Port State Control in Nigeria, Focus Areas and IMO 2026 Inspection Points

Nigeria participates in the Abuja Memorandum of Understanding on Port State Control, which coordinates inspections across West and Central African states. The IMO 2026 amendments will likely trigger concentrated inspection campaigns, as has been the pattern following previous major amendment packages. Understanding the probable focus areas is essential for avoiding detentions.

Likely PSC Focus Areas Tied to IMO 2026 Amendments

Based on prior Abuja MoU campaigns and the substance of the 2026 changes, industry observers expect inspectors to prioritise:

• Lifting appliance certificates and test records (SOLAS Reg II-1/3-13)
• Oil Record Book accuracy and revised Annex I discharge entries (MARPOL)
• Crew training certificates for harassment and bullying awareness (STCW)
• Lost-container reporting readiness and bridge procedures (MSC resolution)
• CII operational records and Ship Energy Efficiency Management Plan (SEEMP) updates (MARPOL Annex VI)
• Onboard anti-harassment policy documentation and crew acknowledgement records (MLC)

Detention Triggers and Remediation Playbook

A detention occurs when a PSC inspector finds a deficiency serious enough to warrant the vessel being held in port until it is rectified. For the 2026 amendments, the most likely detention triggers include missing or expired lifting appliance certificates, absence of crew training records, and failure to demonstrate a functioning lost-container reporting system.

If a deficiency is identified, the recommended remediation sequence is:

• Immediate acknowledgement. Accept the deficiency finding without dispute at the initial inspection stage. Contesting findings on the spot rarely succeeds and may escalate the inspector’s stance.
• Rectification plan. Present a written rectification plan within 24 hours, specifying the corrective action, responsible officer and completion date.
• Class society involvement. If the deficiency relates to a certificate or survey matter, contact the vessel’s classification society immediately to arrange an emergency attendance or remote verification.
• NIMASA liaison. Engage NIMASA’s Maritime Safety Department to confirm that the rectification plan meets the regulator’s expectations and to request release authorisation once the deficiency is closed.

Interaction with Nigerian Reforms, NPERA, Maritime Zones Bill and Tax Changes

The IMO 2026 amendments do not land in a vacuum. Nigeria is simultaneously pursuing domestic maritime reform that will reshape the regulatory landscape. Two legislative initiatives deserve particular attention from compliance teams.

The Nigerian Ports and Harbours Authority Reform (NPERA) is expected to restructure port governance, potentially transferring certain regulatory oversight functions, changing fee structures and redefining the relationship between terminal operators and the federal authority. If enacted, NPERA may alter which entity is responsible for ensuring that port-side waste reception facilities meet the updated MARPOL standards, a practical question that operators should raise with NIMASA and legal counsel now, before the reform takes effect.

The Maritime Zones Bill seeks to define Nigeria’s maritime boundaries and jurisdictional zones in line with UNCLOS. Its interaction with IMO 2026 amendments is significant because enforcement jurisdiction, the geographic reach of NIMASA’s PSC and flag-state inspection authority, is determined by the zones recognised under domestic law. Once enacted, the Bill may expand the areas within which Nigerian inspectors can exercise port-state or coastal-state powers, increasing the enforcement surface for the 2026 amendments.

Operators should also review the interaction between Nigeria’s maritime regulatory environment and the Cabotage Act, which imposes local content and local crewing requirements on vessels trading within Nigerian coastal waters. The 2026 STCW amendments on crew training create a potential overlap: operators must now demonstrate both Cabotage Act crewing compliance and updated STCW training records, a dual obligation that requires coordinated legal and operational planning.

Industry observers expect that recent tax and fee reforms affecting businesses operating in Nigeria will also interact with the cost of IMO 2026 compliance, particularly where equipment upgrades, additional crew training or enhanced waste-handling facilities are required.

Contractual, Insurance and Operational Drafting, Immediate Redlines

The IMO 2026 amendments trigger the need for prompt review of commercial agreements across the shipping chain. Parties who fail to update their contractual provisions risk bearing liabilities that could have been allocated or mitigated through timely drafting.

Charterparty and Liner Terms

Owners and charterers should review the following clause areas:

• Certification warranty. Insert or update a warranty confirming that the vessel holds all certificates required under the 2026 SOLAS, MARPOL, STCW and MLC amendments. Sample language: “Owners warrant that the Vessel complies with all IMO instruments in force as at the date of delivery, including but not limited to amendments effective 1 January 2026, and that all certificates required thereunder are valid and current.”
• Compliance covenant. Add a mutual obligation to cooperate on regulatory compliance, including a duty to share documentation required for PSC inspections. Sample language: “Each party shall promptly provide the other with copies of any certificate, survey report or regulatory notice relevant to the Vessel’s compliance with applicable IMO amendments.”
• PSC detention allocation. Clarify which party bears the cost and delay consequences of a PSC detention arising from non-compliance with the 2026 amendments.

Bill of Lading and Terminal Clauses

Carriers should review their bill of lading terms to ensure that container-loss reporting obligations are addressed, particularly the duty to file electronic reports under the new MSC resolution. Terminal operators should update their standard terms to reflect any new obligations relating to waste reception, crane certification and emergency contact designation.

P&I Coverage Notes

P&I correspondents and members’ brokers should notify the club of the 2026 amendments and confirm that the following areas remain within the scope of cover:

• Liabilities arising from lifting appliance failures on board, including third-party injury and cargo damage
• Pollution liabilities under the revised MARPOL discharge and reporting regime
• Defence costs associated with PSC detentions and regulatory proceedings initiated by NIMASA

All redlined clauses should be reviewed by qualified maritime counsel within 30 days. Operators with fleet-wide charterparty portfolios should prioritise vessels on time-charter, where the allocation of compliance costs between owner and charterer is most commonly disputed.

Practical Templates and Remediation Checklists

To support immediate implementation, the following templates are available for download and adaptation:

• 30/60/90-day compliance action checklist (PDF). A printable version of the checklist set out above, formatted for assignment to responsible officers with sign-off columns and target dates.
• Sample regulator notification letter to NIMASA. An editable letter requesting confirmation of specific amendment implementation timelines, designated contact points and Marine Notice availability.
• Internal compliance certification form. A one-page form for vessel masters to certify that all 2026 amendment requirements have been reviewed, actioned and documented on board.
• PSC remediation log. A structured log for recording deficiencies identified during PSC inspections, rectification actions taken, classification society involvement and NIMASA communications.

These templates are designed as starting points. Each should be reviewed and adapted by the operator’s legal and compliance teams to reflect the specific circumstances of the fleet, the trading pattern and any flag-state-specific requirements. Operators who have navigated Nigerian licensing processes in other sectors will find the regulatory engagement approach familiar.

Conclusion, IMO Amendments Nigeria: Act Now, Not Later

The IMO 2026 amendments are already in force. Every vessel entering Nigerian waters, whether Nigerian-flagged or foreign-flagged, is subject to inspection against the updated standards. The practical effect is that delayed compliance is not a scheduling inconvenience but an active risk: PSC detentions, coverage gaps, commercial disputes and reputational damage in the Abuja MoU database are all foreseeable consequences of inaction.

Operators, terminals and P&I clubs should treat the 30/60/90-day checklist as a minimum standard, adapt the templates provided above, and engage qualified maritime legal counsel to review their contractual, regulatory and insurance positions. The interaction between the IMO 2026 amendments and Nigeria’s domestic reform agenda, including the NPERA and the Maritime Zones Bill, adds a further layer of complexity that justifies early, expert-led compliance planning.
