Though this  video is a bit dated, it does a great job illustrating the installation process. Over time, the subsea interconnecting array cables require periodic reburial. In a recent release, London Array wind farm in the UK highlights the need to monitor and rebury cable that has become exposed over the last few years.

“Cable reburial is required at some locations and care should be taken within the wind farm site to avoid snagging array cables. Although not expected, natural seabed variation may reduce the depth of burial over buried cables without London Array’s immediate knowledge. Snagging cables not only pose a risk to health and safety, but could also cause a serious risk of damage to wind farm assets.”
