Marine Accident Investigations
Marine accident investigations typically refer to investigations involving selected marine accidents on or under the navigable waters, internal waters, or the territorial seas of the United States (US) and accidents involving US flagged vessels that occur beyond US waters.

Assistance for Marine Accident Investigations
Although there is no requirement for the NTSB TDA Division to respond to marine accidents, TDA Specialists work with the NTSB’s Investigator-In-Charge (IIC) who is responsible for leading the safety investigation, the NTSB highway investigative team, and local and state agencies to coordinate assistance and information for survivors, family, and friends, either by telephone or on-scene if launched to the accident. The NTSB TDA Division remains a primary point of contact to survivors, family, and friends during the course of the investigation and provides updates on the release of information associated with the investigation.
Short-term Counseling & Referrals
Short-term emotional support services and referrals are available at the request of survivors, families, or friends at no cost through our partners, the American Red Cross. Please contact the NTSB TDA Division directly for more information or to request this support.
Victim Identification Process
In the US, medical examiners and coroners are responsible for identification, determination of cause and manner of death, and death certification for individuals that either die within their jurisdiction or are transported to their jurisdiction if a death occurs over water. The NTSB TDA Division can provide contact information for the appropriate authority upon request.
The NTSB may take custody of personal effects like personal electronic devises or other items relevant to the investigation. Depending on condition, these items may be returned to the owner or a designed family member typically at the conclusion of the investigation. Personal effects not collected by the NTSB may be collected by the medical examiner or coroner, law enforcement or another agency involved in the response. The NTSB TDA Division can assist with questions about personal effects retained by the NTSB or provide contact information for other agencies that may have personal effects in their custody if known.
The NTSB has the authority to retain control of and manage access to the vessel involved in the accident during the investigation. Inquiries regarding status of the vessel or any vessel components under NTSB control may be directed to the NTSB TDA Division.
The NTSB does not coordinate interviews with media for family members, friends, or survivors. However, media representatives may attempt to contact you after a crash. The NTSB will not release the identities of victims or survivors of accidents. Such information may be released by the transportation operator involved or local authorities.
Marine Accident Investigation Process
Due to the possible complexity of marine accidents and the extensive nature of the investigation process, a marine accident investigation often requires 12 to 24 months to complete. Depending on the circumstances of the accident, the IIC along with other NTSB investigators and party members may travel to the accident location to collect information. The NTSB has the authority to designate organizations, corporations, or agencies as parties to the investigation. Only representatives who can provide technical or specialized expertise are permitted to serve as a party member and report directly to the NTSB. The NTSB will not determine the cause of an accident while on scene.
The following are reports that can be issued during the course of the investigation and accessible on the NTSB’s Marine Accident Reports webpage:
- The preliminary report provides a synopsis of factual information collected during the on-scene phase of the investigation. This report is typically available a few weeks after the accident.
- The final report provides a summary of relevant factual information, analysis, findings, probable cause, and safety recommendations issued or reiterated as a result of the investigation; or an accident brief that consists of a short accident narrative, probable cause, and if issued, safety recommendations. Briefs are normally limited to factual information but may contain analysis. The report or brief replaces the preliminary report and is typically available 12 to 24 months following the accident.
An accident docket contains relevant factual information collected during an accident investigation that is used in the development of reports, briefs, and safety recommendations. The docket is available to access at an appropriate time during the investigation, or at its conclusion.
If safety recommendations or safety alerts are issued because of an investigation, these can be issued at any time during the investigation process.
