For site verification, a prototype GFRP suction pile was produced, and a field test was performed in the field. The prototype hada diameter of 1.8 m and height of 3.0 m. To reduce the penetration resistance and buckling, the tip was reinforced with steel. The test-bed was located international water near the An-ma islands in the West Sea of Korea. The target layer was sedimented sand with SPT N-values of 20~40. The test-bed application showed a self-weight penetration of 0.5 m and a final penetration induced by suction of 2.2 m, which indicated that 96% of its entirebody was successfully penetrated. After penetrating the GFRP suction pile, a diver confirmed the good penetration. Averticality of 1.6° satisfied the criterion of 2.0°. For effective site installation, the site condition (depth, ground condition, etc.) had to be considered carefully to select the suction pressure to apply. The hybrid suction foundations were the group type. Thus, the seafloor condition, waves, and tidal current affected the caisson installation process (e.g., pile installation sequence, suction pressure, and amount of penetration). Therefore, further studies are required to improve the reliability and efficiency.
