Reducing the impact of geohazards
Our approach centres on integrating multidisciplinary datasets within a framework of knowledge, based on our vast global experience in all types of environments.
The combination of remote sensing data – including seismic, acoustic and laser imagery – and geological and geotechnical samples often forms the basis for our work. Specialist logging, testing and analysis provide further detail. Total integration of all information enables us to determine geohazard risk and complete site-specific probabilistic and post-event analyses.
When geohazards can’t be avoided they must be mitigated and their impact reduced to an acceptable level. We provide the platform for geohazards specialists to work seamlessly with geotechnical engineers to address these risks. As well as informing and guiding the engineering design process, based on the sensitivities and parameters of soil units, we advise on the design of remedial actions to rectify immediate issues and mitigate against future potential risks.
If you’re selecting the optimal location for a structure on land or on the seabed, the risks of exposure to quantified geohazards will be a constraint. The same is true if you’re choosing a route for a linear installation, such as a pipeline or road, where there will also be installation constraints to consider.
By applying sophisticated probabilistic approaches to assess the relative importance and sensitivity of individual constraints, we can address these concerns and help guide your decision-making process towards the lowest-cost solution.
