Summary
Divers investigating leaks at a subsea manifold followed approved procedures based on incorrect client information. Fault-finding revealed a different jumper configuration, leaving only one unproven barrier during intervention. Work stopped pending confirmation of safety; the client investigated without identifying how the error arose, and amended drawings were formally approved.
