Lessons learned

When accidents happen at sea, we study them to make shipping safer. These 'Lessons learned' are simple, practical safety tips based on real-world investigations. They help everyone in the industry learn from the past to prevent future accidents.

These Lessons learned capture the essential elements of an incident: what happened, why it happened, the safety issues involved, and the potential preventive measures translated into practical guidance. Their purpose is to simplify complex investigation findings into accessible, actionable knowledge that can help seafarers, Administrations, training institutions, and industry stakeholders better understand the root causes of maritime accidents.

For the maritime industry, Lessons learned offer significant benefits: they enhance safety awareness, highlight recurring human‑element and operational risks, and promote the adoption of preventive practices. By sharing these insights globally, IMO helps reduce the likelihood of similar casualties reoccurring, supports harmonized safety standards, and reinforces the culture of continuous learning. The material serves as an important tool for improving training, updating safety management systems, and informing both regulatory and on‑board decision‑making.

The Lessons learned are reviewed, refined, and approved by the Sub‑Committee on Implementation of IMO Instruments (III) before being circulated to the maritime community. This structured approval process ensures that every Lesson learned is accurate, relevant, and aligned with IMO's objective of preventing future accidents and enhancing global maritime safety.
