Passenger Accounting: The Accuracy of the Roll-Call after Costa Concordia

During the Costa Concordia sinking, no one carried out a roll-call or counted the people who had boarded lifeboats and liferafts: a single procedural failure that made it impossible, for days, to know with certainty who was missing.

Operational Explanation

Passenger accounting is the process by which the ship verifies, in an emergency, that all passengers and crew are actually present at their respective assembly stations, comparing the attendance recorded with the passenger manifest and the muster list. The investigation into the Costa Concordia sinking (2012) found that no one carried out a roll-call or counted the people who had boarded lifeboats and liferafts during the evacuation: a failure that made it harder, in the following days, to establish with certainty who was actually missing.

Shipping companies take different approaches to emergency roll-call: some rely on an actual name-by-name roll-call at assembly stations, others arrange a systematic search of every area of the ship by the crew in the absence of an automated counting system. On the regulatory side, in the United States the Cruise Vessel Security and Safety Act (CVSSA) requires companies to report every disappearance to the competent authorities (including the Coast Guard and the FBI for US citizens), with public quarterly reports still ongoing in 2025.

Regulatory Reference

SOLAS Regulation III/8 (Muster list and emergency instructions) as the procedural basis; Cruise Vessel Security and Safety Act (CVSSA), United States: obligation to report every disappearance to the competent authorities (Coast Guard, FBI for US citizens), regardless of the status of investigations, with public quarterly reports from the Department of Transportation still ongoing in 2025.

Scope of Application

Every passenger ship, with particular relevance for emergency counting procedures at assembly stations and for ships subject to CVSSA (embarkation/disembarkation in the United States).

Procedure / How to Complete It

  1. Clearly define, in the emergency procedure, the counting method adopted at assembly stations (name-by-name roll-call against the muster list, or systematic search of the ship's areas).
  2. Ensure that the person in charge of each assembly station has the up-to-date list of people assigned to that station.
  3. Systematically compare the attendance recorded with the passenger manifest and the muster list, immediately reporting any discrepancy to the bridge.
  4. For ships subject to CVSSA, keep the procedures for reporting disappearances to the competent authorities up to date, regardless of the status of internal investigations.
  5. Include the counting discipline in crew training as a mandatory step of evacuation, not as an optional activity if time allows.

Practical Example

Example: during an abandon-ship drill, the person in charge of an assembly station carries out the name-by-name roll-call against the assigned list, immediately reports to the bridge two names found absent, and waits for confirmation before declaring the station complete, following the Company's documented procedure.

Real Cases

The investigation into the Costa Concordia sinking documented that no roll-call or systematic count was carried out during the evacuation, a factor that added to other procedural shortcomings of the emergency; the episode remains the most frequently cited reference case in the industry to illustrate why counting cannot be left to individual initiative at the moment, but must be a written and exercised procedure.

PSC Observations

Although emergency passenger accounting is not typically the subject of direct PSC verification, PSCOs may check the documentation of the counting procedure in the muster list and in recorded exercises, and, for CVSSA ships, the consistency of disappearance reporting procedures.

FAQ

What did the investigation into the Costa Concordia sinking reveal about passenger counting?
That no one carried out a roll-call or a systematic count of the people who had boarded lifeboats and liferafts during the evacuation, making it harder to later establish with certainty who was actually missing.
What does the CVSSA require regarding missing persons on board?
That every disappearance be reported to the competent authorities (Coast Guard, FBI for US citizens), regardless of the status of the company's internal investigations.
What counting methods do cruise companies typically use at assembly stations?
Some carry out a name-by-name roll-call against the muster list, others arrange a systematic search of every area of the ship by the crew, in the absence of an automated counting system.
