Abstract
The great efficiency and deep-sea suitability of floating offshore wind turbines (FOWTs) have led to their rapid development. It is also extremely difficult to regulate FOWTs. Two major obstacles are the increased component failure rate and the difficulty of accurately modelling FOWTs. For that reason, this study suggests a model-free adaptive fault-tolerant control strategy to deal with problems caused by blade root moment sensors. In order to sidestep the need to mathematically describe FOWT, a fault compensation and individual pitch controller are developed using a model-free adaptive control technique. Instead of requiring fault detection and isolation, the suggested fault-tolerant control scheme turns fault dynamic compensation into a nonlinear system's control issue that has to be solved in real-time. By simulating and testing the suggested control method using FAST, we find that it not only keeps the wheel's bearing load balanced, but it also greatly reduces the FOWT's bearing load and the floating platform's movement. Also, the strategy's great fault tolerance capabilities under numerous blade root moment sensor failures is confirmed by the fact that the output power is closer to the rated power.

Description of the data and file structure
From 2015 to 2019, 6,924 wind turbines from more than 10 countries were located in this dataset, which offers geocoded information on OWTs worldwide. With data accessible at a spatial resolution of 10 m, an explicit dataset is provided for the purpose of maritime space planning, monitoring, and management. The global dataset is referred to as the WGS84 data. Each record consists of seven characteristics: continent, nation, centroid latitude and longitude, sea area, appearance year, and appearance monthcord.

Description: This dataset contains detailed geospatial and temporal information on 6,924 offshore floating wind turbines (OWTs) located across more than 10 countries. The data are specifically designed to support maritime spatial planning, monitoring, and management activities. Data were acquired between 2015 and 2019, providing a comprehensive global view of OWT distributions at a high spatial resolution of 10 meters.
The dataset includes the precise geocoded location of each OWT, along with key metadata, including the country, continent, sea area, and the time of appearance (in year and month) for each wind turbine. All geospatial data are recorded using the WGS84 coordinate system, which ensures consistency in global positioning.

Offshore wind turbines (FOWTs) have grown significantly due to their deep sea suitability and high power generating efficiency. However, FOWT control is challenging. FOWT modelling accuracy and component failure rates are the key issues. This research suggests a model-free adaptive fault-tolerant control strategy for blade root moment sensor failures. Using model-free adaptive control, an individual pitch controller and fault compensator are created to circumvent mathematical modelling of FOWT. Our fault-tolerant control technique eliminates the requirement for fault detection and isolation, turning fault dynamic compensation into a real-time issue for nonlinear systems. FAST simulations demonstrate that the proposed control technique effectively balances wheel bearing load, reduces floating platform movement, and greatly reduces FOWT bearing load. Additionally, the strategy's output power is close to the rated power, demonstrating remarkable fault tolerance with numerous blade root moment sensor failures.
