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)
