Submarine Landslides

Offshore infrastructure like wind farms, telecommunication cables, pipelines, and oil and gas facilities encompass vast areas and are therefore subject to a wide range of geohazards (Figure 1). In planning, designing, and building offshore infrastructure, integrated site characterizations are required to understand local and regional features and develop the data needed to design and identify geohazard exposures. Because of the complexity of these projects, we rely on these integrated marine site investigations using field and laboratory data, modeling and simulation outputs, and experts’ knowledge to identify and characterize submarine threats and produce earth models that can guide risk-based decision-making. In doing so, we can conduct seabed investigations in stages, refining structure locations as the presence and risk of geohazards are confirmed.
