Environmental Alert 01/2015: Inspection and Monitoring of BOP control lines (link)
This DECC Environmental Alert reports on a recent incident on a MODU in which both the yellow and blue multiplex (MUX) control lines of the installation’s primary BOP control system were found to be impaired.
Operators and drilling contractors are reminded of the requirement to critically review the configuration of the assembly used to attach the BOP MUX cables to the slip joint and to otherwise ensure that the arrangement of these lines in the moon-pool area is sufficiently robust to prevent damage even during severe weather conditions.
