Summary
A saturation diver sustained a left-arm lost-time injury during subsea high-pressure water jetting when the gun failed and a component detached. The flash identifies loose locking bolts, inadequate nut retention, unavailable manuals and maintenance shortcomings. Actions included management of change, equipment-condition checks and a dive-team awareness briefing.
