Suction Bucket Foundation (Multi-type) Experiments
【Soil tank experiment (Insertion and pull-out)】
As in the mono-type experiment, we verified the penetration of the bucket by pumping and draining water inside the bucket. We also conducted an experiment to control the inclination and vertical penetration by adjusting the drainage volume of each bucket.
【Hydraulic model experiment (Scour)】
Since multiple suction bucket foundations (multi-legged type) are installed on the seabed in close proximity to each other, the water flow around the foundation is more complicated than that of a mono-legged type foundation. Hydraulic model experiments were conducted to understand such scouring characteristics.
【Field demonstration test】
After conducting laboratory soil tank tests, we conducted a demonstration test of a suction bucket test model (multi-type) about a 1/5 scale model size in order to verify the workability of a larger-scale model.
Since the multi-type can independently control the amount of penetration by adjusting the drainage volume of each individual bucket, we confirmed that the structure has sufficient control capability for the vertical accuracy required for offshore wind power foundations.
