Following protracted de-trenching operations, the cable has
been cut and one of the ends recovered onto the repair vessel for fault
location testing.

Probably nicked by copper thieves in scuba kit...

"On 26th June 2011 at 0417 a fault was recorded on one of two 250 MW
cables that comprises the Moyle electricity interconnector, which
connects the electricity systems of Northern Ireland and Scotland. As a
result, the Interconnectors capacity for the transfer of electricity
between Scotland and Northern Ireland has been halved. The fault has
been confirmed as a short circuit between the integrated return
conductor and earth. Testing has shown the fault to be located offshore,
approximately 17km from the Northern Ireland shoreline in a water depth
of 140m."

"Due to the nature of working offshore, a typical repair schedule for
this type of fault could be in the region of six months."

Wonder if they used something similar to TDR to locate the fault?

To lose one 450MW cable could be regarded as unfortunate, to lose two
looks like carelessness. :-)
