[0002] Various anchoring systems are known in the art, including driven, suction and embedded anchoring systems. However, such systems have been found to have several shortcomings. The commonly used anchoring systems are limited to use on specific seabeds. This is costly and time consuming. Floating offshore wind (FOW) projects often experience significant variations in geological conditions within a single site. As a result, traditional anchor systems are not suitable for site-wide use. In addition, offshore wind projects require foundations with many anchors. Therefore, it is costly to use conventional anchor systems. Summary of the Invention

There are one or more sections on the thin part of the main body of the anchor pile, each of which is having a cross section larger than the cross section of the part itself or any one or more of its joints The cross section has a bulge from the top to the bottom of the body, which reduces This forms at least one bearing, which in use forms an annular groove that receives the lock. At least one of the support parts is formed between the support part and the part adjacent to the hole. In this case, the anchor pile is The locking device is secured in the annular groove so that sufficient friction is created on the locking device's base. This friction occurs between the bearing and the soil. The anchor pile is adapted to receive the locking medium in the annular groove. The result of sufficient frictional resistance resulting from the body being in intimate contact with the bearing and the appropriate load-bearing soil layer at the hole. As a result, it is locked into place within the hole.

The protective sheath increases the load-bearing surface of the mooring lines while increasing the frictional resistance. In addition, the protective sheath may incorporate load-bearing components such as steel plates to provide load-bearing support against the formation. This can increase the load and further reduce the axial load in the anchor pile. Such load bearing members may be attached directly to the mooring lines. In one embodiment, the present invention provides an apparatus that is configured to only partially damage when damaged. The anchor system is designed to prevent damage to the entire system. In particular, the thin part of the body is entirely supported by the aggregate in the borehole. During peak loads, the aggregate (which acts as a semi-fluid) and the fine particles of the body The loose part may move axially along the borehole or become dislodged. Each time the load drops below a certain level, the locking medium is reset within the annular groove. This allows the bearing surface at the narrowest part of the body to continue to exert high friction while The hole is then locked into place. [Brief description of the drawings]
