Offshore Cables & Wind Farms

Accurate weather assessments are essential to the safety of offshore cables and wind farms. A thorough assessment of water depth, distance to shore and wind speeds will increase performance and help lower costs. Our specialists at Aktis Hydraulics are highly experienced in assessing seabed dynamics at the landfall for offshore cables and wind farms.

They achieve this by analysing:

- (Satellite or survey based) shallow water bathymetry;
- Long-term and short-term seabed dynamics at landfall areas;
- Depth and stabilisation requirements;
- Installation technique, cost optimisation and risk assessment;
- Geo-hazards, including effects of underwater landslide
  s and turbidity flows;
- Environmental impact.

Approach

By combining statistical analysis of seabed data and risk analysis for a cable or wind farm, our experts can define a burial depth that is technically feasible and cost-effective, while securing long-term pipeline and cable integrity.

This involves:

Determining seabed variation for the short term (seasonal and yearly) and long term (over ten years)
Combining both short and long-term variations to calculate the lowest seabed level during the design life
Determining the required burial depth based on the long-term integrity (stability, free span and risk analysis)
