Abstract
The suction bucket foundation is installed on the seabed under combined self-weight and under-pressure. In this case study, four submersible monitoring structures for the active sensors were constructed on the ultra-soft seabed using suction bucket foundations. After construction, the excessive displacements of the column top due to the external excitation were measured. The cause analysis of the problem carried out and the reinforcement method to reduce the excessive displacement were applied. As the review results, the excessive displacements were developed for the connection rigidity problem between suction foundation and upper part column. Adopted reinforcing method was additional bettered stiffener mounting. Finally, the angular displacements at the same underwater excitation test after the reinforcement were reduced nearly designed value.n bucket foundations.
