Summary
An ROV dropped to the seafloor during recovery when its umbilical parted at the cursor rail transition. Faulty resin casing and improperly arranged armoured strands compromised the attachment despite a previous successful pull test. BSEE recommends termination inspection procedures, re-termination training and pre-job connection checks. No personnel harm or seabed asset damage occurred.
