Summary
A diver was fatally struck by a high-pressure water jet while relocating a marker buoy beside a leaking live injection pipeline. Reduced visibility and extreme noise hindered the dive. The flash discusses risk understanding, initial ROV inspection, safe depressurisation, task-specific hazard analysis and formal communication of work instructions.
