TenneT of the Netherlands Deploys Satellite Technology to Monitor Construction of 263 Transmission Towers

en.Wedoany.com Reported - On November 9, Dutch transmission system operator TenneT selected domestic satellite monitoring technology company Orbital Eye to provide satellite remote sensing monitoring services for the Rilland–Tilburg 380 kV high-voltage transmission line construction project. The project route spans approximately 80 kilometers and involves the construction of 263 transmission towers. TenneT will use the COSMIC-EYE monitoring platform developed by Orbital Eye to regularly obtain data on construction activities along the route and conduct remote supervision of project progress, construction equipment, and temporary work facilities.

Under the cooperation arrangement between the two parties, the COSMIC-EYE platform will combine satellite imagery and data analysis technology to submit weekly construction activity monitoring reports to the TenneT project team. The monitoring scope covers earthworks, temporary construction roads, work platforms, construction machinery, and building material storage areas along the route, and identifies changes in construction sites through satellite imagery from different periods.

The monitoring system can simultaneously observe multiple construction areas along the route, identifying machinery activity, changes in temporary construction facilities, and material storage conditions. TenneT project managers can use the satellite monitoring results to understand the activity status of each construction area, identify locations requiring further on-site verification, and use the relevant data for construction plan coordination and project progress management.

The Rilland–Tilburg transmission project is an important component of the 380 kV grid expansion plan in the southwestern Netherlands, connecting Rilland in Zeeland with Tilburg in North Brabant. The line project involves multiple contractors, among which Hanab Energy Solutions, in cooperation with Italy's SELT, is responsible for part of the line and transmission tower works in the Moerdijk to Tilburg section, including 138 transmission towers and the stringing of four circuits.

According to the project construction plan, the new Rilland–Tilburg transmission line will be integrated with some existing 150 kV transmission facilities. Some of the new transmission towers can simultaneously carry 380 kV and 150 kV lines, and the related works also include 150 kV underground cable connections and adjustments to existing transmission facilities. The satellite monitoring service will be used during the ongoing line construction process to support TenneT in continuously tracking the work areas of different contractors.

Orbital Eye is headquartered in Delft, the Netherlands, and was founded in 2012. Its COSMIC-EYE platform has previously been applied to the monitoring of critical infrastructure such as energy pipelines and has provided related technical services to transmission system operators in France and Germany. In this TenneT project, the platform is being applied to the supervision of large-scale high-voltage transmission line construction, with monitoring data provided to the engineering project team in the form of weekly reports.
