“For shipping companies, maritime security professionals and regional policymakers assessing piracy risk in the Gulf of Guinea, this Ambrey Insight is an evidence-based analysis of counter-piracy legislation and enforcement across Nigeria, Cameroon, Togo and Ghana. Unlike assessments focused solely on legal reform, it compares statutory powers with recorded naval responses, arrests and prosecutions—showing that stronger laws improve the prospects of conviction but cannot materially reduce maritime risk without faster interdiction, sound evidence handling and disruption of shore-based criminal networks.”

EXECUTIVE SUMMARY

• Ambrey assesses that the counter-piracy legislation adopted by Nigeria, Cameroon and Togo has strengthened national legal capacity across the region to prosecute piracy and related maritime offences. Ghana’s Parliament passed the Maritime and Related Offences Bill 2026 on 30 June 2026. As of 29 July 2026, Ambrey had not identified public confirmation that the Bill had received presidential assent.
• Nigeria and Togo provide the clearest regional evidence that arrests connected to maritime attacks can progress to prosecution and conviction. Ambrey has not identified comparable outcomes under Cameroon’s 2022 legislation, while Ghana’s proposed framework remains untested.
• Between 22 July 2019 and 29 July 2026, Ambrey recorded 28 kidnapping, boarding or extended-duration robbery incidents involving merchant vessels in Nigeria, Cameroon, Ghana and Togo. A national naval response was reported in 16 incidents.
• Between the same dates, Ambrey identified limited evidence of arrests following reported naval responses. Nine suspected perpetrators were arrested during Nigerian operations associated with the assessed incidents, while no confirmed arrests were identified following responses in Cameroon, Ghana or Togo. Of the nine arrested, three were successfully prosecuted.
• The Nigerian navy have posted arrests recorded on-shore, this study focuses on arrests occurring at sea during an incident.
• Ambrey assesses that the legislation improves the prospects of prosecution after suspects and evidence have been secured. It is unlikely to materially reduce the immediate threat to shipping without corresponding improvements in surveillance, response readiness, evidence preservation and investigations targeting shore-based criminal networks.

THREAT CONTEXT

Following the passage of Ghana’s Maritime and Related Offences Bill 2026 by Parliament, Ambrey assessed the counter-piracy legislation and demonstrated enforcement capabilities of Ghana, Nigeria, Cameroon and Togo.

Piracy in the Gulf of Guinea is enabled by shore-based networks that provide intelligence, finance, weapons, transport and access to negotiators. Naval intervention can disrupt an attack or recover a vessel, but its longer-term effect depends…
