Summary
An investigation examines an oxygen manifold rupture during diving support aboard a lift boat at South Pass 28. Fragments injured a contract diver testing the new system. Findings identify non-oxygen-clean ball valves and rapid pressurisation, despite prior controlled testing. The report discusses missing written procedures and a temporary return to single-cylinder supply.
