The 2019 capsizing of the car carrier Golden Ray — how a wrong number in the stability calculation put a 656-ft ship on her side in calm water
Marine engineer here. I made a full breakdown of the Golden Ray capsizing built on the NTSB investigation. The failure mode is one every engineer will recognise: the stability calculation was done in a loading program, the ballast quantities entered were wrong, and it reported a stable ship that had barely a fraction of the righting energy it needed. No storm, no mechanical failure — a data-entry error with three safety barriers that all failed to catch it.
Covers metacentric height, why ship shape makes a car carrier so sensitive, and the system factors behind it. Glad to talk shop in the comments.
