Structural-geotechnical Interaction of Moorings of Floating Systems
Anchoring systems are key components of the support structure of floating platforms and their design includes many opportunities for innovation and challenges to delivering reliable performance. Mooring systems are known in the oil and gas industry to be a potential source of reduced reliability, and implementation of mooring systems for floating platforms will require deeper understanding of the interaction of structural and geotechnical behavior. Among the challenges to the design of new mooring systems, the following are prioritized for discussion in this panel: cyclic loading and soil uncertainty, optimization of mooring architecture, and mooring and anchor design for intermediate and shallow water depths.
