The Investigations Division carries out all the statutorily mandated investigations of commercial vessel casualties and reports of violation that require a determination for apparent cause and culpability (fault). The findings of Coast Guard Marine Casualty Investigations are used to create safety recommendations to prevent future marine casualties. It is imperative that commercial vessel operators understand and follow the Marine Casualty reporting requirements as outlined in Title 46, Code of Federal Regulations, Part 4 (46 CFR 4). Without timely and truthful reporting, the Coast Guard is hampered in its ability to conduct an accurate investigation. Therefore, responsible parties that fail to report Marine Casualties as required by regulations are subject to civil penalties.

U.S. law, specifically Title 46, U.S. Code, Chapter 61 (Reporting Marine Casualties), Chapter 63 (Investigating Marine Casualties), and Chapter 77 (Suspension and Revocation) provide the core concepts governing the Coast Guard's responsibilities for Marine Casualties and Personnel Actions. The statutes, as written, are broad in nature and are supplemented by more extensive regulatory requirements set forth in Title 46, Code of Federal Regulations, Part 4 (Marine Casualties and Investigations) and Title 46, Code of Federal Regulations, Part 5 (Marine Investigation Regulations - Personnel Actions).

The primary purpose of an investigation is to ascertain the cause or causes of an accident, casualty, or personnel behaviors to determine if remedial measures should be taken and to determine whether any violation of Federal Law or Regulation has occurred. The results of such investigations play a major role in changing current and developing new laws and regulations, as well as implementing new technologies in areas of U.S. Coast Guard concern.
