Truls Helevik, a 31-year-old Norwegian diver serving on the Byford Dolphin oil rig, died in a decompression accident upon resurfacing from underwater in a diving bell. The chamber-lock was released prematurely which caused his environment inside the bell to go from nine atmospheres of pressure to one in a fraction of a second, causing the gasses and blood in his internal organs to undergo sudden rapid expansion. Helevik’s body violently exploded with his remains being blown-through a 24 inch diameter hole at the top of the diving bell, rocketing 30 feet into the air and raining blood, organs and bone-fragments over the oil rig. Three other divers and four technicians were also killed in the event.
