AB-FLS-NX5

Next-generation offshore wind and metocean measurements

Our floating LiDAR technology is utilized for offshore wind and metocean surveys, aiding in the feasibility assessment of wind farms and informing critical decision-making.

OWA Stage 2

AB-FLS-NX5 is a local assembled Floating LiDAR System based on the world’s first wind and metocean measurement system that has reached the Best Practice of OWA Stage 2 for 3 different LiDAR models. The verified LiDAR configurations include both WindCube V2 Offshore and ZX 300M, and dual Molas B300M LiDARs.

Turbulence Intensity Correction

The Tl analysis for ZX 300M LiDAR installed on AB-FLS-NX5 conducted by Oldbaum Services Limited shows that the corrected Tl data during the 6-month campaign compared with Inch Cape met mast in Scotland meets the Best Practice according to CFARS guidelines with our motion compensation algorithm.

Value

  2. Provide critical decision data for wind farm design and investment evaluation to improve investment certainty
  3. Provide data services for marine meteorological monitoring and forecasting
  4. Provide data support for marine disaster forecast warning modeling

Security

  • Abidance by international HSE standards
  • Data is encrypted for transmission and securely stored in the customer’s local server

Accuracy

  • High raw data quality from specific buoy design
  • State-of-the-art motion compensation algorithm
  • Multiple third-party reports with OWA Stage 2 Best Practice
  • Post-processing TI data with Best Practice

Reliability

  • Dual LiDAR system with both continuous wave and pulse wave LiDARs
  • Full redundancy to eliminate single-point failures

Resilience

  • High survival rate after collisions, and structure design with multiple cabinets to prevent sinking if any water ingress
  • Proven track records of extreme weather experiences (violent storms, high temperatures, freeze and snow, rainy season, etc)

Outstanding collision endurance design

Dual AIS, dual navigation light
The combination of dual AIS system and dual navigation light provides redundant protection and reliable navigation information for the system, helping the vessels make better navigation decisions and reduce navigation accidents.
Double reinforcement protection rings

Double reinforcement protection rings can effectively withstand external impact, protect critical components of the system, and avoid functional failure or damage caused by external impact.

Multiple solid cabinets
The system is designed with multiple cabinets, which have sufficient residual buoyancy even when all hulls are full of water to prevent the system from sinking under extreme circumstances.

Sufficient power supply for one-year offshore measurements free of maintenance

Solar panels
Multiple groups of solar panels (total generating power 2464W) can optimize the collection and utilization of solar energy to ensure continuous and stable power supply.
Wind turbines
Dual redundant wind turbines(total generating power 2 * 350W) fully use offshore wind to provide continuous power to the system.
Fuel cell (optional)
Dual redundant fuel cells serve as a backup power source, providing stable power in extreme environmental conditions and enhancing the system’s adaptability to global environments.

Site-specific mooring options

• The system is designed to utilize a combination of a 12-ton cement block anchor and a 1.5-ton anchor that offers substantial holding power. The anchor chain features a double-point connection and is connected by a saddle chain. This design has been rigorously tested and validated under various typhoon conditions, demonstrating its reliability and effectiveness.
• According to the characteristics of the project site, considering the marine environment, geological conditions, and other factors, the multi-anchor mooring system can be customized.
• With the position monitoring function, the system automatically triggers a warning when the offset position exceeds the safe range.
