A full-flow penetrometer is utilized as a site characterization tool in this paper to estimate the pullout capacity of a deep sea anchor foundation. The penetration of a full-flow (ball) penetrometer is first modeled in an explicit dynamics model to identify the zone over which maximum shear stresses are generated. The soil in this zone is assumed to have reached remolded shear strength, based on soil sensitivity (which was taken between 1.0 and 4.0). The pullout capacity of the anchor is determined in a separate finite element analysis, where the soil is characterized using remolded or undisturbed shear strengths. The results of numerical analyses for a soil sensitivity of 1.0 appear to match published field test data.
