ESA has padeye on its side wall so as to be pulled out in any direction. In addition, embedded suction anchor2 (ESA2) that has padeye on both sides can be pulled out in vertical direction. A series of centrifugal tests were conducted to evaluate the maximum vertical pullout capacity of a suction pile embedded in sand by varying the diameter and the length of the anchors. The loading point was located at the top. An experiment shows that the maximum pullout capacity increases as the length and diameter of ESA2s increases.
The results show that the pullout capacity increases with increasing diameter and length of suction pile. The effect of length of ESA2 on the pullout capacity seems to be negligible, while diameter has meaningful effect. From this observation it might be concluded that it is more efficient to increase the diameter of ESA2 rather than length to improve the capacity.
