Aircraft Warning Markers

Innova AS has been assigned a contract by Statnett for development of a robotic tool for installation of Aircraft Warning Markers, AWM, on high-voltage power lines. The robot is designed for autonomous installation of AWM onto power line shield wires by helicopter. The shield wire is positioned above the conductors and acts as an earth wire for the power line assembly.

As the installation is fully autonomous, personnel risk is significantly reduced as only the helicopter personnel are involved during operation. Installation of the AWM’s can be performed with full power on the lines, hence reducing cost. In addition, the robotized installation saves time as the autonomous installation is by far faster than manual installation.

The development of the AWM-robot is divided in the following main tasks:

  • Concept study
  • Engineering and preparation of detail drawings
  • Development and fabrication of prototype robot
  • Testing of prototype
  • Qualification of technology
  • Fabrication of robots for operation

During the development, Innova AS has been working with both Statnett and their AWM-suppliers in order to ensure full interface-control and an optimized technical solution. By working as an integrated team, the technical solution is optimised in every aspect providing a safe and economical method for installation of Aircraft Warning Markers.

We have successfully installed marker balls on energized powerlines. The qualification program for live-line operation has been completed.

Innova AS is pleased to bring our expertise within remotely operated tooling to new areas and markets. This project is absolutely true to our slogan “Innova shall be a leading company supplying knowledge and competence within complex, polytechnic solutions in demanding environments”
