We provide focussed solutions in pipeline design for projects in which pipe-soil interaction is a key design driver. Our expertise in soil and pipe-soil interaction behaviour, coupled with our numerical analysis experience offers advanced pipeline-soil interaction analyses. As part of the SAFEBUCK JIP, we have helped the industry to develop better soil models for lateral buckling behaviour of pipelines.

We have also combined our pipeline, soil and seismic expertise to offer analysis and verification solutions to the problems of seismic induced seabed hazards on pipelines.

As a recognized expert, we provide clients with state-of-the-art pipeline-soil response models which are calibrated to our extensive database of laboratory and in-situ tests.

Pipeline analysis

Our combined understanding of the soil and the pipeline system is a significant asset in the understanding of pipeline behaviour in difficult soil conditions.

At Cathie, we deliver solutions for wherever offshore infrastructure interacts with the seabed. From basic analytical design according to established codes through to advanced and innovative computational methods using the most advanced finite element, finite difference and emergent methods in conjunction with machine learning. Designing with the express intent of lowering CAPEX, managing installation risk and improving reliability.
