An electrical technician was killed on October 26, 2025, while working inside an elevator shaft aboard P&O Cruises' Arvia, a Bermuda-registered cruise ship. The UK Marine Accident Investigation Branch (MAIB) has issued interim findings on the incident, classifying it as a "Very Serious Marine Casualty." The central finding is unambiguous: the elevator was not electrically isolated while the technician was in the shaft.
The sequence of events, as described in the MAIB findings, is a textbook lockout/tagout failure. The technician was working on a passenger lift that had a defective door release key on Deck 12. Because the key was defective, the technician could not access the shaft from that level and instead entered the hoistway from Deck 14. The Arvia does not have a Deck 13, following the common maritime superstition. When the shaft doors closed behind the technician, the safety interlocks re-engaged. A stored call signal that had been queued in the elevator controller then sent the car upward. The technician was crushed in the shaft.
The LOTO Failure
Every elevator mechanic who reads this will identify the root cause immediately: the elevator was live. Lockout/tagout exists for exactly this reason. When a technician enters a hoistway, the equipment must be electrically isolated at the disconnect. Not put on inspection, not taken out of service through the controller, not assumed to be safe because the doors are open. Electrically isolated. The power must be off, and the disconnect must be locked in the off position with the technician's personal lock. That did not happen here. A stored hall call sitting in the controller's memory was all it took to move the car once the interlock circuit was restored by the closing doors.
The defective door release key on Deck 12 is a contributing factor that compounded the LOTO failure. If the key had been functional, the technician would have entered the shaft at the intended level. But a malfunctioning key should not force a technician to improvise shaft access from a different floor on a live elevator. The correct response to a defective release key is to lock out the elevator, then address the access problem. The sequence got inverted, and it was fatal.
Not the First Time
This is not the first fatal elevator incident on a cruise ship. In 2015, a crew member was killed in a similar shaft incident aboard the Carnival Ecstasy. The maritime elevator environment presents specific challenges that differ from land-based installations: maintenance crews on ships may not be IUEC-trained elevator constructors, lockout/tagout protocols may not mirror OSHA-regulated jobsite standards, and the organizational separation between the ship's electrical department and the elevator equipment may create gaps in who is responsible for isolation procedures. None of those factors excuse what happened on the Arvia. They describe the environment in which it happened.
For elevator mechanics working on land-based installations, this incident is a reminder that the fundamentals are non-negotiable. LOTO is the single most important safety procedure in the trade. It is the one thing that stands between a technician and a car that can move. The Arvia fatality happened because someone entered a shaft without confirming the equipment was dead. That is the entire story. Everything else, the defective key, the stored call, the deck numbering, is context around a single preventable failure. The MAIB investigation is ongoing, and a final report is expected to include recommendations for the maritime elevator maintenance industry.
