Pipelines, cables and Scour Protection Services

Pipelines and Scour Protection

We have extensive knowledge and experience in offshore seabed and coastal sediment movements and the interactions of offshore pipelines and cables with the seabed. We apply this experience to improve the design of pipelines and scour protection measures. Please see the drop down menu for more detail on these services.

Our services include, but are not limited to:

Seabed mobility, sand waves migration and pipeline burial criteria
Landfall morphology and trench sedimentation
Pipeline free span evolution and pipeline burial
Local scour assessment and scour protection design
Offshore pipeline and cable risk assessment
Wind Farms and cables
Ambient and extreme metocean conditions
Detailed atmospheric modelling

Approach

We apply a variety of models and tools for predicting coastal evolution and free span behaviour (e.g. PIPESIN, CROSMOR and LONGMOR). Using the outputs from the models, in conjunction with analysis of wave, current, sediment composition and historical depth data, we can predict the autonomous sea-bed development and how it is likely to interact with structures and pipelines.
