Offshore geotechnical problems involving an object penetrating in clay is commonly considered under undrained condition. It is known that the Tresca constitutive model can be modified to include rate-dependent and strain-softening (RDSS) soil strength. Currently many researches adopt the RDSS in total stress analysis and do not compute the excess pore-pressure generated during penetration. This study demonstrates a successful integration of an incompressible effective stress analysis (IESA) to simulate excess pore-pressure generation and RDSS in re-meshing and interpolation technique with small-strain (RITSS) framework. Commonly encountered offshore geotechnical problems such as pipeline installation and punch-through of spudcan penetration are employed to demonstrate the robustness of the proposed integration.
