Description

Technical Field

[0001] This invention belongs to the field of mooring system technology, and particularly relates to a mooring device for a multi-functional floating wind power platform at sea. Background Technology

[0002] With the rapid development and maturation of seawater desalination and hydrogen production technologies, offshore platforms are evolving towards larger sizes and more multifunctional applications. In offshore wind power systems, a platform with a certain distance (called an air gap) from the water surface is typically installed inside the offshore wind farm for functions such as pressurization, seawater desalination, or hydrogen production. This platform is generally referred to as a multi-functional platform and usually has a multi-layered structure. In shallow waters, it is typically secured to the seabed using pile foundations.

[0003] However, in deep waters, the increased depth means that continuing to use fixed foundations would significantly increase the construction costs, difficulty, and time required for offshore wind farms. Therefore, when the water depth exceeds a certain value (such as 80m), the platform is usually configured as a floating platform.

[0004] Floating wind turbine platforms differ from traditional floating structures in two ways: 1) they incorporate a wind power generation system on the floating body, thus subjecting them to significant wind-induced tilting moments; 2) the large mass, height, and distance from the water surface of the wind turbine nacelle cause substantial changes in the platform's motion characteristics under extreme wave action, placing higher demands on the stress distribution and stress on the mooring system. These issues lead to significant pitching motion in floating wind turbine platforms, posing significant challenges to their structural safety and power generation efficiency.
