FLiDAR - Neart na Gaoithe (NNG) Validation Campaign:

RESULTS

FLiDAR Technology Overview

2

FLiDAR technology Overview

3

• WindCube on gimbal system

• Motion of LiDAR decoupled

from buoy motion

Data quality independent from

buoy movement

Possible to validate

independent from sea state

Buoy structure no influence

on measurements

V0.9 Buoy

Replaced with

V1.0 Buoy

Unchanged

Gimbal

Unchanged LiDAR

& Software version

FLiDAR technology Overview

Design Improvements from V0.9 to V1.0

4

• Buoy structure changed to a Mobilis platform:

• Significant weight reduction (~ 6 Ton)

• Improved handling during O&M, symmetrical hull

• 4 independent floating compartments

• Faster/cheaper multi-cat crane deployment (<10 ton)

• Uses two point mooring:

• Adds redundancy in case of failure

• Keeps the buoy aligned on a N-S axis = more

efficient use of PV panels, less yaw compensation

• Switch to Li-Ion batteries:

• Increased capacity by 70%

• No changes to core measurement system (LiDAR,

software algorithm & gimbal mechanical compensation)

V0.9

V1.0

MRP-NNG campaign & FLiDAR technology Overview

Design Improvements V1.1

5

• Symmetrical design

• Upgraded energy system

• Increased PV production by 70%

• Added 1 extra WTG

• Possible to install Fuel Cell

• Increased redundancy and reliability

on sensor and PC loggers

• Upgraded satellite and GPRS
