With Nigeria’s maritime sector growing in size and complexity, managing ship-generated waste has become a critical environmental and regulatory concern. From international cargo vessels to offshore support ships and naval fleets, every vessel operating in Nigerian waters is responsible for disposing of waste according to MARPOL and local environmental laws.

This article examines the state of ship-generated waste management in Nigeria, the regulations governing it, the types of waste involved, and how Wigmore Trading supports compliant waste handling through logistics, equipment sourcing, and port infrastructure services.

What Is Ship-Generated Waste?

Ship-generated waste refers to any waste produced during the normal operation of a vessel. Under the International Convention for the Prevention of Pollution from Ships (MARPOL), ship waste is classified into several categories:

1. Oily Waste (Annex I)

Includes bilge water, oil sludge, and waste lubricants from engine rooms. Requires proper segregation, treatment, and offloading at port reception facilities.

2. Noxious Liquid Substances (Annex II)

Primarily relevant for chemical tankers, this includes cargo residues and cleaning agents.

3. Harmful Substances in Packaged Form (Annex III)

Items such as expired chemicals, batteries, or toxic substances stored onboard.

4. Sewage (Annex IV)

Black water from toilets and medical facilities, which must be treated or safely offloaded.

5. Garbage (Annex V)

Food waste, plastics, packaging materials, and other solid refuse generated by the crew.

6. Air Pollution and Emissions (Annex VI)

Although not physically collected, this includes emissions regulations for fuel and exhaust systems.

Regulatory Environment in Nigeria

Nigeria enforces ship-generated waste regulations through both international and national frameworks:

• NIMASA (Nigerian Maritime Administration and Safety Agency): The lead agency for MARPOL enforcement, vessel inspection, and monitoring of Port Reception Facilities (PRFs).

• Federal Ministry of Environment / NESREA: Ensure proper environmental protection measures for waste disposal.

• Nigerian Ports Authority (NPA): Manages port waste reception facilities and contractor oversight.

• Licensed Waste Management Firms: Collect and treat waste in compliance with MARPOL and Nigerian law.

Vessels operating in Nigerian waters must log and report waste generation and discharge activity, with failure to comply resulting in fines, detention, or blacklisting.

Challenges in Nigeria’s Ship Waste Management

• Insufficient Port Reception Facilities (PRFs) in some smaller ports

• Delay in waste barge clearance and logistics bottlenecks

• Lack of onboard waste treatment systems on older vessels

• Non-compliance due to knowledge gaps or cost-cutting

• Illegal dumping offshore due to poor enforcement in some zones
