Truls Hellevik from Top 10 Worst Deaths in History

The most known accident is connected with the Byford Dolphin, a semi-submersible, column-stabilized drilling rig. In 1983, during drilling operations, a group of divers, together with Truls Hellevik, were inside a decompression chamber system when the chamber explosively decompressed from a pressure of nine atmospheres to one atmosphere. 3 of them, including Truls, died immediately.
