Floating LiDAR System,Dual LiDAR
Fast, accurate, and reliable technology for data-driven offshore wind development.
Blue Aspirations was founded to accelerate the global adoption of renewable energy by harnessing the power of data. Using our software development and engineering expertise, and a team with more than a decade of experience in the renewables industry, we partner with clients who share our passion for sustainability and our ambition to tackle the challenges of the next century.
Reliability is the most important feature of any floating Lidar system and is a core tenet of Blue Aspirations’ design philosophy . Drawing on our team’s expertise in design principles from the telecommunications industry, the system emphasizes redundancy in its key components. The commercial model was also iteratively designed using simulations to model failure paths and eliminate single point of failures. Key examples of how these principles are embodied in the floating Lidar system include:
Since the motion of the buoy affects LiDAR wind direction and wind speed measurements, Blue Aspirations’ system is equipped with a motion sensor to acquire high-resolution pitch and roll data, and heading and DGPS sensors to obtain accurate heading information. Our patented algorithm then uses a projection method to correct the LiDAR wind speed data to the appropriate horizontal plane. By calculating the LiDAR installation angle offset from the heading sensor’s true north, the system is likewise able to transform the collected wind direction data to the correct angle.
