Suction Bucket Foundation Experiment (Mono-type)

【Soil tank experiment (Insertion and pull-out verification)】
We conducted insertion and pull-out tests to verify penetration and pull-out only by draining and injecting water into the bucket. Flow rate, water pressure, ground resistance and displacement were measured, and the mechanism was analyzed.

【Hydraulic model experiment (Scour)】
“Scouring” is caused when the soil around the foundation is washed away by currents, and it can cause the foundation to become unstable. We conducted hydraulic model experiments to understand the scour characteristics of suction bucket foundations as well as other foundations (monopile, jacket) and studied the characteristics of each type of foundation.

【Field demonstration test】
Subsequently, we conducted a demonstration experiment in an actual sea area to verify the workability of a larger scale model (1/4 scale). For the penetration and pull-out work, a pump system developed in-house was installed on the bucket and the amount of water being pumped was operated and controlled from a control room on a work vessel.
