Buoyancy resistance pile for subsea structure installation

A buoyancy-resistant pile for subsea structure installation, the buoyancy-resistant pile comprising:

• a pile main body including:
• one end configured to be buried in a seabed or a concrete foundation;
• a hollow portion;
• an inner tube surrounding the hollow portion;
• an outer tube surrounding the inner tube;
• a concrete material filled between the inner tube and the outer tube;
• and
• at least one through-hole defined to penetrate an outer circumferential surface of the pile main body and extending to the hollow portion;
• and
• at least one pull-out resistor coupled to the outer circumferential surface of the pile main body by being inserted into the at least one through-hole, and configured to be buried in the seabed or the concrete foundation,
• wherein a ratio of an exposed length of the at least one pull-out resistor that is exposed outside of the pile main body to a total length of the at least one pull-out resistor is between 0.5 to 0.65, and
• wherein the at least one pull-out resistor includes a plurality of pull-out resistors spaced apart around the outer circumferential surface of the pile main body.
