The FLiDAR system

Measuring the power of the sea

with Navex Elektro Belgium

The FLiDAR measurement buoy represents a major breakthrough for the offshore wind industry,

enabling major cost reductions for offshore wind resource assessments. Development companies

considering the deployment of new marine renewable technologies such as offshore wind, wave

and tidal energy will find the FLiDAR very useful. It can be deployed in one day and delivers highly

accurate data throughout the project development, with real-time data access. It has been proven

to measure wind potential with an accuracy equivalent to fixed offshore met masts, regardless of

the sea state.

The business concept of FLiDAR is based on a rental model with data service agreement, minimising financial

risk and maximising flexibility for the customer. As quality, dependability and full-time availability are key

aspects, the developers of FLiDAR turned to Navex Elektro and Mastervolt for the onboard energy supply.

The basics

n

To ensure full-time operation at sea, long

periods of autonomous power supply must be

guaranteed, even when solar and wind power

generation are far below average.

n

All power needs to be supplied at either 12 V

or 24 V DC.

n

Measuring and controlling all (redundant)

onboard energy consumers and sources

remotely, again to ensure full-time operation

and, if necessary, timely service.
