The Wildrake diving accident was an incident in Scotland in August 1979 that killed two American commercial divers. During a routine dive in the East Shetland Basin of the North Sea, the diving bell of the diving support vessel MS Wildrake became separated from its main lift wire at a depth of over 160 metres (520 ft). Although the bell was eventually recovered by Wildrake, its two occupants, 32-year-old Richard Arthur Walker and 28-year-old Victor Francis "Skip" Guiel Jr., died of hypothermia. The accident resulted in extensive subsequent litigation and led to important safety changes in the diving industry.
