UT Drone for offshore inspections■

Current Issues–■

Technical Solution and the Benefits–■

UT(Ultrasonic Testing) inspections at offshore platform contains certain risk of safety and have less efficiency due
to the harsh environments and unique difficulties.

Replace manual inspections with inspections executed by a “UT drone”.
•No Risk of Working at heights.

•

Reduction of Working in confined spaces.

•Prevention of downtime due to rope access, installation of scaffolding and conventional inspection.

How we can make it happen–

Making the drone suitable for harsh outdoor environments.(Water and Wind resistance)–

Developing a versatile robot arm mounted on the UAV, suitable for different sensors (UT and Visual).

–

Developing a versatile clamping/gripping mechanism for various structures like pipes.

–

Data can be managed on a Cloud platform. Data can also be used together with 3d model or LiDAR data.

Why we would like to develop this module■ Limitation of Drone

・Drone should attach to wall by 3 point = Drone need large flat surface to inspect© 2020 Terra Drone Corporation. All Rights Reserved.

Problem of this design■ Drone becomes heavy, flight time will be shorter.
→ 15min to 5min

■ Drone becomes very big, there are many point drone cannot
reach.
→ 500mm*700mm*400mm to 500mm*700mm*800mm© 2020 Terra Drone Corporation. All Rights Reserved.
