Summary

The port exhaust gas boiler (economiser) of the UK registered Princess Cruises liner Island Princess ruptured killing two people and injuring three others during sea trials in the Bay of Naples on 7 December 1997. No passenger were onboard at the time.

Safety Issues

  • safety valves on the port economiser had remained shut throughout the entire episode and did not lift under pressure because the spindles had seized in their guides
  • poor quality boiler water and leaking safety valves created the conditions that weakened the spindles corrosion resistance
  • there was a previous history of safety valve seizures and economiser overpressure and rupture

Recommendations

Multiple recommendations to a number of parties have been made as a result of this investigation.
