Maritime casualty investigation, a key responsibility as a flag and coastal State under various multilateral International treaties including UNCLOS, SOLAS and MARPOL, is the focus for an in-depth national training course on marine accident and incident investigation in Yangon, Myanmar (4-15 May). The two-week training course is based on IMO Model Course 3.11 (Marine Accident and Incident Investigation) and aims to ensure the consistent application of the Code of International Standards and Recommended Practices for a Safety Investigation into a Marine Casualty or Marine Incident (Casualty Investigation Code), in order to establish the root cause of an accident with a view to introducing measures to stop such an accident happening again.
