LainePoiss®

real-time wave data

LainePoiss® is affordable buoy that measures sea/ocean wave height, period and other properties. It follows sea surface movement to capture wave parameters. LainePoiss® can be used as drifter or moored buoy. Calculations are made in real-time inside the device and sent to the server using wireless communication. Buoy is lightweight, compact, durable and made to survive in ice water. The measurement method is validated by multiple tests in laboratory and in real world. It is easy to deploy and returns accurate real-time data from the sea. LainePoiss® can be used for various monitoring, engineering and research applications. Buoys have collected years' worth of valuable data at sea.

Applications

• Marine conditions monitoring, analysis and forecasting
• Marine construction projection
• Environmental change monitoring and analysis
• Wave energy generator analysis and design optimization
• Offshore wind power farm monitoring
• Scientific research

• Ruhnu island inhabitants rely their lives on a ferry traffic and Ringsu harbour is the gateway. In certain wave conditions it is unsafe for the ferry to enter/leave the port and a possible mitigation would be extending the protective pier. LainePoiss® is used to quantify the wave regime around the harbour to find the best configuration of the new pier. This work is done in cooperation with Lainemudel OÜ and Saarte Liinid AS.

Ease of Use

LainePoiss® is lightweight and compact. This makes deployment possible using small boat. Device is started and stopped using magnet. Waterproof connector on the top of the device make it possible to recharge internal battery and get access to collected data without using any tools. There is no need to open the buoy hull and risk water ingress.
