150kV cable failure: Rampion Wind farm - UK

150kV cable failure: Rampion Wind farm - UK

150kV cable failure: Rampion Wind farm - UK

(OP)
I read that the subject wind farm, commissioned in 2018, is down since 26th Oct'2019 due to failure of under-sea HV cable.
Any details how it failed, is it a straight-through joint or some thing else!!

RE: 150kV cable failure: Rampion Wind farm - UK

A future fault? (It's only the 13th Nov now).

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Thanks LitleInch for pointing out my mistake. Corrected - 26th Oct'19.

RE: 150kV cable failure: Rampion Wind farm - UK

Sorry, being a bit smart.

There doesn't seem much out there in public, but they did replace section back in 2017 before the start so maybe something failed in that replacement.

And something in the original placement? Starting to add up to something bigger now.

ax1e, you mean the plant is still not back on line!
Cable terminations and joints are always weak spots in the cable and if it is not done properly first time, we are in for tough time.

RE: 150kV cable failure: Rampion Wind farm - UK

At present, the damaged section of the cable has been removed. Before reinstallation, the project team will carry out rubble removal work in relevant waters.
However, this is not the first such failure for this wind farm. As early as last December, the eastern one of the two sea cables were damaged due to unknown reasons, and part of it was dismantled and reinstalled in March and April this year. This time the problem is the western cable. Is it an accident that two sea cables were damaged in a short time? Is it not buried deep enough?
