To study the feasibility and efficiency of underwater suction anchors in soil, the performance of eight model anchors was evaluated in a 30 in. (76.2 cm) by 72 in. (183.0 cm) by 32 in. (81.3 cm) deep test tank. The soils studied were a medium fine sand, a silt and a clay. A gantry-type loading mechanism was used to apply the vertical breakout force. A pullout rate of approximately 0.1 in/min (0.25 cm/min) was used for all tests. For the range of conditions studied, the test results indicate that the underwater suction anchor is feasible and effective. The breakout behavior of the suction anchors depends upon the anchor geometry including anchor diameter and skirt length, soil strength properties, soil-anchor friction and adhesion, and suction; i.e. the difference between the pressure underneath the porous plate and the ambient pressure.
