This was a joint Industry Project (JIP) to study the response of clay soils to the deflection of a pile with large, lateral cyclic loading and erosion of stiff clay due to repeated lateral loading. Studies involve an evaluation of the continuum mechanics and the finite element methods, and the P-Y method, in solving the problem of determining soil response for offshore structures. In-situ data and undisturbed samples for laboratory testing will be obtained from sites where major pile experiments were conducted.

To study designs of tension-leg platforms (TLP); to understand how platform foundations interact with the soil to influence the stability and reliability of the platform; to identify research topics and to initiate work on topics identified as being critical.
