56 FOGHORN which caused catastrophic mechanical damage to the engine.” One lesson learned from this incident reminds vessel operators of the need to be vigilant in conducting emergen- cy drills including firefighting. The quick action by the vessel crew to se- cure machinery space ventilation and fuel supply lines resulted in removing two elements of the fire tetrahedron and thus extinguishing the fire. The other lesson learned in this inci- dent is that the manufacturer’s planned maintenance and service schedules such as oil changes need to be followed to mitigate the risk of equipment mal- function or premature failure. NTSB OFFICE OF MARINE SAFETY DATA DASHBOARD The NTSB recently released an inter- active dashboard that summarizes and visualizes NTSB marine investigations occurring from 2012 to the present. According to the dashboard website, data for investigations occurring before 2012 will be added in future releases. Users can view data using the Investi- gation Map and Case Summary dash- board pages. Both dashboard pages can be filtered by event date, vessel name(s), case status (open or closed), NTSB ves- sel group, and NTSB casualty category. Investigation Map: This dashboard page is an interactive map showing NTSB investigations all over the world. The color of each map dot corresponds to the type of vessel(s) involved. Note: While “passenger” vessel en- compasses both foreign and domestic passenger and small passenger vessels, PVA is seeking a delineation between foreign cruise ships and domestic pas- senger and small passenger vessels in a future update to the dashboard. Case Summary: This dashboard page provides statistical graphs show- ing the number of investigations by NTSB vessel group and NTSB casu- alty category. The data table below the map and graphs provides basic casualty infor- mation and links to the investigation page and docket for each selected investigation. More detailed infor- mation for each investigation can be found on the investigation page, linked by NTSB Number in the first column and in the docket URL linked in the second column. PVA staff have a very good working relationship with the NTSB Office of Marine Safety. The NTSB is the only federal organiza- tion that performs independent, com- prehensive, and transparent investiga- tions to determine the probable cause of marine accidents, with the goal of making safety recommendations to prevent similar events from occurring in the future. While operating jointly or concurrently with the Coast Guard on major marine casualties, the NTSB will release their own final reports that may not align with the Coast Guard’s conclusions and recommendations. NTSB is also less constrained by potential or actual criminal investiga- tions by the Department of Justice. SAFETY MATTERS The new NTSB interactive dashboard visualizes investigations by the agency since 2012.
