Floating-type foundation for supporting a wind power generation system and including a stabilized power cable, system of floating-type foundations, and a method of stabilizing the power cable

A floating foundation for supporting a wind turbine, the floating foundation comprising:

• a column extending upwardly and couplable at a top end thereof to a base of the wind turbine;
• and
• a station keeping system, wherein the station keeping system comprises:
• at least one semi-taut or taut mooring line detachably attached to the floating foundation at one end and detachably attached to a seabed anchor at an other end thereof;
• and
• fittings that connect the semi-taut or taut mooring line to the floating foundation and to the seabed anchor,
• wherein the at least one semi-taut or taut mooring line is configured to connect, disconnect, and reconnect to the fittings of the mooring line and of the seabed anchor, and
• wherein when the semi-taut or taut mooring line is connected to the floating foundation and the seabed anchor, a departure angle of the at least one semi-taut or taut mooring line is between 35 and 55 degrees with respect to a vertical axis of the column.

A system of floating foundations for supporting a plurality of wind turbines that generate power, the system comprising:

• a plurality of floating foundations;
• and
• at least one power cable that is an inter-array power cable for transferring generated power between the plurality of floating foundations and/or an export power cable for exporting the generated power to an offshore/onshore station,
• wherein each of the plurality of floating foundations comprises a column extending upwardly and couplable at a top end thereof to a base of a wind turbine;

A method of stabilizing a power cable connected to a floating foundation supporting a wind turbine, the method comprising:

• determining an optimal number and position of a plurality of buoyancy modules to be disposed on at least one power cable;
• installing the plurality of buoyancy modules in the at least one power cable according to the determined optimal number and position;
• deploying the floating foundation and the at least one power cable into a water body,
• wherein the at least one power cable is an inter-array power cable for transferring power generated by the wind turbine to or from another floating foundation and/or an export power cable for exporting the generated power to an offshore/onshore station,
• wherein the optimal number and position of the plurality of buoyancy modules are determined based on at least a distance between the floating foundation and the another floating foundation or the offshore/onshore station, and
• wherein the at least one power cable with the plurality of buoyancy modules is positioned in an optimal submergence range of the water body due to the number and position of the plurality of buoyancy modules.
