Description

Technical Field

[0001] The present disclosure relates to the field of wind power technology, and in particular to a floating foundation dynamic positioning device. Background Art

[0002] Floating foundations are widely used in deep-sea oil and gas, wind power and other energy development. Floating foundation types generally include Spar type, TLP type and semi-submersible foundation. Among them, Spar type mainly controls its water entry depth and stability through ballast tanks, TLP type provides buoyancy through central columns and buoys, and semi-submersible foundations provide buoyancy through columns and beams. All three types of foundations rely on anchor mooring. Floating foundations are subject to heaving and swaying motions under the influence of ocean currents, wind and waves, and long-term motions may cause damage to mooring systems, superstructures, etc.

[0003] Existing technical methods generally reduce the heave and swing amplitude of the floating foundation to avoid the risk of structural damage by optimizing the structural design, layout design, mooring system design, etc. However, considering the complexity of marine environmental loads, there may be uncontrollable factors that cause the movement amplitude of the floating foundation to exceed the expected value, and the early optimization design cannot provide later assistance.
