A. Ocean mammal monitoring with underwater acoustic acquisition device
Our floating LiDAR can be equipped with an underwater acoustic acquisition device, digital Hyd TP-1. It's designed for real-time streaming of digital data for remote storage, processing, and/or visualization. This device has internal processing capabilities allowing, alternatively, to stream results such as spectral analysis. The TP-1 hydrophone is ideal for integration into monitoring buoys or readily existing systems, or it can be connected directly to a computer.
Features
This digital hydrophone features a pre-amplifier combined with a programmable gain amplifier (PGA) with 7 different gains, for convenient adjustment of the overall sensitivity according to expected incoming signals’ amplitudes. The device is equipped with an analog-to-digital converter with a wide range of selectable sampling rates up to 312500 samples per second at 24 bits. The TP-1 is a telemetry-based hydrophone that features a 10/100 MBit/s ethernet interface, which allows direct connection to a computer, or to a wired or wireless network for real-time data streaming to a client that can handle the acoustic data for storage, processing, and/ or visualization. A power/ ethernet cable for power supply and two-ways communications can be supplied.
The TP-1 digital hydrophone has internal processing capabilities, where FFT based data analysis can be carried
out and results can be made available through a low-speed serial link.
It features various configurations, including selectable sampling frequencies, programmable sensitivity, and acoustic data
processing modes.

Despite the risks of building and operating wind farms in locations prone to severe weather, many of China’s offshore wind farms are developed in high-risk areas. Yet typhoons and other extreme events can pose formidable challenges to wind and met ocean measurement campaigns without proper preparation. As the market leader in China, Blue Aspirations’ floating Lidar system is designed to address precisely these challenges. The system integrates backups for all main components, fuel cells to supplement power from solar panels and wind turbines, and a dual-LiDAR setup in its standard configuration. For added protection, its hull also incorporates a large counterweight and residual buoyancy that mitigates the risk of capsizing or sinking. Truly robust typhoon resilience can only come from sturdy structural design, redundant systems design, and diligent operational support.
CHABA TYPHOON CASE STUDY
On July 1st, 2022 Typhoon Chaba passed through a prospective site for offshore wind farm development in the South China Sea. The site was amid a wind measurement campaign using an industry-standard ZX 300M Lidar integrated into a Blue Aspirations FLiDAR.
Typhoon Chaba originated in the south and headed northwest for several days before landfalling in Guangdong province. Chaba brought maximum sustained wind speeds of approximately 140 km/hr, maximum wind gusts of 170 km/hr, and maximum wave heights of 10.67m. Despite these extreme conditions, our unit continued operating effectively – achieving data availability for all measurement heights at 100%, marking the third occasion this floating Lidar system continued to function without issue amidst typhoon conditions.
We would like to include in this document a summary of the reports from our clients or from third parties nominated by our clients that support our data accuracy and data availability claims.
