Case Studies

High-voltage submarine power cables are used extensively in offshore energy. To mitigate risks associated with laying power cables on the seabed, cables are typically buried in the top layer of sediment. To ensure cable integrity is maintained, the safe working...

Subsea power cables are integral to the offshore energy industry. The consideration of risks associated with a cable’s intended route will include the level and type of vessel activity in the area, with design mitigations such as trenching likely to...

Offshore environmental conditions can lead to localised changes in seabed levels, exposing buried subsea power cables, resulting in unintended free spans. Free spanning cable sections present a risk to the operator as loading imparted on the exposed cable could lead...
