What happened

A fire destroyed a variable-speed drive in Sleipner B's high-voltage room, causing smoke, soot and firefighting-water damage and a prolonged production shutdown. The normally unmanned platform was empty, so nobody was endangered. Havtil considered an electrical fault the most likely cause but could not determine it conclusively, and identified seven regulatory breaches.

When cited sources give different casualty, damage or spill figures for this event, they’re reported side by side above rather than merged into one number. See how confidence levels work.
