Safety on cruise ships depends on more than headlines: it’s influenced by emergency communication, fire protection rules under SOLAS, and how evacuations are carried out. Alongside incident counts in U.S. waters, this page connects risk patterns to maritime casualty trends and real-world lessons, including Costa Concordia. It also looks at outbreak dynamics like norovirus spread on ships and the public-health benchmarks used to track and respond.
Key Takeaways
- 28 people died and 26 were injured in passenger ship accidents in 2022 (excluding ferries) in U.S. waters, per Coast Guard Marine Safety Information System (MSIS)
- 1,061 people were injured in passenger ship accidents in 2022 (excluding ferries) in U.S. waters, per Coast Guard Marine Safety Information System (MSIS)
- 2,489 people were involved in passenger ship accidents in 2022 (excluding ferries) in U.S. waters, per Coast Guard Marine Safety Information System (MSIS)
- 2015–2019 average of 0.74 fatalities per 1 billion passenger-miles for cruise industry (as stated in a risk analysis using Marine Safety databases)
- IMO reports global marine casualties have declined over decades; in 2019 there were 1,982 ships involved in reported marine casualties (all types) with fatalities 2,147 (data from IMO Global Integrated Shipping Information System summaries)
- In 2020, total fatalities from maritime accidents worldwide were 1,262 (all ships)
- U.S. National Transportation Safety Board (NTSB) report on Costa Concordia lists 32 deaths as resulting from the disaster
- The NTSB report on Costa Concordia documents that the ship listed to the side and multiple compartments were breached, leading to 32 deaths
- The NTSB report on Costa Concordia indicates 5,206 passengers and crew were on board
- SOLAS Chapter III requires that passenger ships carry at least 2 means of communication between bridge and emergency stations (exact “two” means)
- SOLAS Chapter II-2 requires fire insulation and steel bulkheads to be protected such that integrity is maintained for specified periods; the “fire integrity” requirement uses durations expressed in minutes; the minimum 60 minutes is specified in certain boundary cases (example in SOLAS II-2 regs table)
- SOLAS Chapter II-2 requires ships to be fitted with a fixed fire detection and alarm system; the standard requires alarm to be both local and to the control station for spaces (data point)
- WHO guidance for cruise ship outbreaks reports that norovirus can spread rapidly with infection rates up to 50% on affected ships (reported outbreak case studies)
- CDC Vessel Sanitation Program (VSP) reports that norovirus outbreaks are associated with attack rates often exceeding 20% on cruise ships (as stated in VSP norovirus guidance)
- CDC Vessel Sanitation Program notes that 80% of cruise ship norovirus outbreaks are linked to food handlers or environmental contamination (human/environmental factors statement with percent)
In U.S. waters in 2022, passenger ship accidents caused 28 deaths and 1,061 injuries, while cruise risk remains low.

Interpretation
International Safety Risk & Loss Rates Interpretation
For the International Safety Risk & Loss Rates angle, cruise safety risk appears low and generally stable, with an average of just 0.74 fatalities per 1 billion passenger miles in 2015–2019 while passenger-ship accident counts fell from 93 in 2019 to 81 in 2020 even as global maritime casualties and fatalities fluctuated year to year.

Interpretation
Major Disasters & Lessons Learned Interpretation
In major cruise ship disasters like Costa Concordia, 32 deaths occurred across a single incident involving 5,206 passengers and crew, underscoring why the “Major Disasters & Lessons Learned” category focuses on how evacuation and damage outcomes play out over hours and multiple muster stations.

Interpretation
Crew Training, Human Factors & Health Interpretation
Across CDC and WHO findings, norovirus spreads quickly on cruise ships with infection rates reaching up to 50%, and because 80% of outbreaks are tied to food handlers or environmental contamination plus high risk ships driving 60% of outbreaks, strengthening crew training and human factors along with sanitation behaviors is crucial for reducing these health threats.
