Offshore Cables and Wind Farms

Accurate weather forecasts are essential to the operational 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 BMT Ship & Coastal Dynamics is highly experienced in assessing seabed dynamics at the landfall for offshore cables and wind farms.

They achieve this by analysing:

  • Satellite-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 landslides and turbidity flows
  • Environmental impact

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)
