Summary
This investigation examines a fatal economiser rupture aboard Island Princess during sea trials. Water heated by engine exhaust overpressurised an isolated, unvented boiler whose safety valves had seized shut. Two people died and three were injured. Findings address valve corrosion, boiler-water quality, unsuccessful venting and corrosion fatigue cracking.
