Molas B300M - Bankable Floating Wind LiDAR System for Offshore Wind Measurement

  • Fully Classified by DNV-GL according to IEC61400-12-1 ed2
  • Cost Effective – Under massive production
  • Robust Design – IP67 protection

Molas B300M is a wind measurement lidar specially designed for the marine environment by Movelaser. It not only inherits all the advantages of Molas B300, such as high measurement accuracy, strong environmental adaptability, and high protection level, but also adds corrosion resistance and other design, which can be fully adapted Marine salt fog, high humidity and other environments. Prior to this, Molas B300M has been used in marine uplift stations, drilling platforms, wind tower platforms and buoys for many times. The Molas B300M used in the buoy system integrates a self-developed motion compensation algorithm, which can ensure high-precision measurement of wind speed in the motion attitude.

The Molas B300M floating wind LiDAR is based on all-fiber coherent doppler effect, through the 4-beam VAD scanning vector synthesis technology, can measure wind speed and direction in 30-300 m above the lidar. In addition, air temperature, humidity and other parameters can be measured by the sensor module. Molas B300M has the characteristics of high precision, stable system performance, maintenance friendly and data security. Its Onshore versions Molas B300 has been tested by DNV-GL Type specification classification test (equivalent to DNV Stage 3 certification),.

Site Deployment of Molas B300M Offshore Wind LiDAR

Nanjing Movelaser Technology Co., Ltd. and Jiangsu Blue Aspiration Technology Co., Ltd. have carried out close cooperation on many floating lidar wind measurement projects in China, and launched a number of Molas B300M offshore wind measurement lidars. The total service period is more than 24 months.
Since the cooperation between the two parties, the lidars of many offshore wind measurement projects have been operating normally and performed well. The average data integrity rate of each measurement altitude of the lidars of the projects that have been put into operation has exceeded 99%, which is our company’s offshore wind measurement lidar. The stability and reliability of Molas B300M provide a lot of data support and practical verification.

Blue Aspiration NX series floating lidar wind measuring device adopts Molas B300M lidar produced by Nanjing Movelaser Technology Co., Ltd. This lidar is based on the Molas B300, which is the only domestic wind-measuring lidar that has obtained the DNV-GL IEC classification certification.

Molas B300M not only has the characteristics of large range and high precision, but also further improves the protection level and anti-salt corrosion performance of the whole machine compared with onshore products, which can meet the harsh use environment at sea. Molas B300M lidar can be applied to various application modes such as pre-offshore wind measurement, wind power prediction supporting wind measurement for offshore wind power projects, etc. Since it was put into the market, as of March 2022, Molas B300M lidar has won a total of five buoy radars in China, Japan, India, and other countries, wind measurement of various offshore platforms, and power prediction of offshore booster stations. With the application performance of more than ten units, the average data integrity rate is over 98%. Currently, Molas B300M has been installed in many floating lidar wind measurement projects in China.
