Marine Geomechanics

The design of offshore and nearshore foundations, submarine cables, pipelines, and other marine infrastructure requires specialized expertise to address the complex geologic, hydraulic, and environmental conditions encountered in the coastal and offshore environment. Successful projects depend on a thorough understanding of seabed conditions, soil behavior under cyclic wave and current loading, installation methods, long-term performance, and constructability considerations unique to marine settings.
