Summary
This fatal diving incident update examines secondary life support activation after a trapped umbilical interrupted primary breathing gas during subsea spool relocation. Delayed completion of two-stage activation accelerated gas depletion. It reports equipment testing, refresher training and drills, and a decision to replace two-stage systems with single-stage activation.
