Seabed dynamics

Local erosion of seabed material around offshore foundations (scour) can become so severe that it jeopardizes foundation stability. Our specialists have ample experience with the assessment of scour around offshore foundations, such as (but not limited to) monopiles, jackets, gravity-based foundations, and jack-ups. Within projects where scour development is critical, we are capable of creating and testing scour protection layouts to aid our clients in their design process.

At Deltares, we use our expert knowledge and physical model tests from the preliminary design phase to final design validation and verification, covering topics such as:

Predictions of local scour and edge scour around offshore structures, design of conceptual scour protection layouts, physical modelling to validate scour protection designs, evaluation of field data, but also less obvious topics such as estimations of winnowing depths.
