The standard is designed to be applicable to all materials, but with a significant caveat. For materials with anisotropic properties (where wave propagation speed varies with direction) or other structural properties that affect wave physics, special care shall be taken , and a specific assessment is required to determine if the guideline is adequate.

Engineers begin with simplified analytical equations to check the pipeline’s susceptibility. This stage evaluates the seabed slope profile, expected temperature profiles, and pipe-soil friction coefficients. If the driving forces (e.g., gravity on a steep slope combined with thermal expansion) exceed the stabilizing friction capacity during a thermal cycle, the pipeline is flagged for advanced analysis. 2.
