Nigeria Safety Investigation Bureau Launches Inquiry into Major Maritime Incident
The Nigeria Safety Investigation Bureau (NSIB) has initiated an investigation into the collision involving the Singapore-flagged container ship MV Maersk Valparaiso and the Nigerian-flagged oil tanker MT Lady Martina. This incident occurred on May 20, 2026, at Bonny Anchorage in Rivers State, and has been classified as a serious maritime accident.
The designation of “serious maritime accident” aligns with definitions set by the International Maritime Organization (IMO), indicating that the incident could involve total loss of the vessel, loss of life, or significant environmental damage.
Following the collision, five crew members aboard the MT Lady Martina sustained varying degrees of injuries. They were subsequently evacuated to the FOB Bonny Sick Bay for medical treatment. The accident also resulted in an oil spill in the vicinity, raising environmental safety concerns.
Within two days of the incident, the NSIB deployed its “go teams” to board both vessels and interview captains and essential crew members as part of the preliminary investigation. The agency has secured operational records and navigational data pertinent to the incident.
In a report released on Friday, the NSIB confirmed that data from the Voyage Data Recorder (VDR) and the Electronic Chart Display and Information System (ECDIS) of the MV Maersk Valparaiso had been successfully retrieved. This data will undergo comprehensive forensic and navigational analysis. The NSIB has also formally engaged with the Singapore Transport Safety Investigation Bureau (TSIB), identifying it as a crucial stakeholder in this investigation.
The NSIB assured the public and the maritime community of its commitment to conducting the investigation with the highest standards of professionalism and independence. The agency aims to thoroughly identify the causes and contributing factors of the incident, which is essential for enhancing maritime safety protocols.
The conclusion of the investigation will see the release of a final report that discourages speculation about the incident. The NSIB has emphasized that it is premature to draw conclusions at this time and has urged all interested parties to avoid making assumptions while the investigation is ongoing. Should urgent safety concerns come to light during the process, the department will promptly issue recommendations designed to prevent similar occurrences and strengthen maritime safety standards.
