During the two-year trial, two prototype Lidar devices were installed beside the existing met mast at the project in the North Sea. The devices were supplied by Belgian group Flidar and UK-based Babcock International.
Certification group DNV GL independently reviewed the technology and found it to be an accurate measurer of wind speeds.
Babcock International said following the trial, its floating Lidar has reached stage two (pre-commercial) of the Carbon Trusts Offshore Wind Accelerator roadmap.
The roadmap outlines stages the technology needs to reach to become commercially accepted as an alternative to installing met masts.
RWE said the results from the trial show floating Lidars are progressing well towards being an effective source of data.
The trial also highlighted the ease and lower cost of installation of floating Lidars and the ability to move them around the project site to gather a wider range of data.
DNV GL principal engineer Simon Cox said: "Floating Lidar technology continues to demonstrate its potential to reduce the cost of measurements for offshore wind power, with two devices now independently assessed against a robust, yet practical, set of industry acceptance criteria."
At the start of February, the Carbon Trust announced to test floating lidar devices at sites around the UK.
The OWA is a collaborative programme aiming to reduce offshore costs. It is backed by some of the industry's biggest developers, including Dong Energy, Vattenfall, RWE Innogy, SSE and E.on.
