SANTIAGO, Chile — Ecocopter by Helisul and BBosch have introduced Human External Cargo (HEC) technology to Chile, enabling specialized helicopter operations for the inspection, maintenance and repair of energized high-voltage transmission lines while reducing intervention times by up to 80%.
The partnership combines BBosch's expertise in electrical engineering and transmission infrastructure with Ecocopter by Helisul's experience in complex helicopter operations. Using specially equipped helicopters, certified technicians can be transported directly onto transmission towers and power lines, allowing work to be carried out safely without interrupting electricity supply.
Cristián Henríquez, Key Account Manager of Ecocopter by Helisul: "The introduction of HEC technology in Chile marks an important milestone for specialized aviation and for the development of high-value solutions for the energy sector. These operations require precise coordination between flight crews and technical specialists, supported by rigorous procedures, advanced training and the highest safety standards. Following our first successful HEC missions, we have strengthened our capabilities to undertake highly complex work with efficiency, precision and professionalism."
Traditionally, maintenance on transmission lines in remote areas required lengthy ground access, complex logistics or dedicated maintenance windows. HEC operations allow technicians to be inserted directly at the work site, improving the efficiency of inspections, installations, maintenance and repairs on energized transmission infrastructure.
Juan Carlos Rodríguez, ADC Leader for Live-Line Operations at BBosch: "HEC technology enables us to reach difficult locations quickly and safely, significantly reducing intervention times while expanding our capabilities for energized-line work. The solution strengthens operational continuity for our customers and contributes to more efficient and resilient transmission networks."
Ecocopter by Helisul operates Airbus H145 helicopters with pilots specially trained for complex aerial work. The aircraft can precisely position personnel and equipment on transmission infrastructure, particularly in mountainous regions, mining districts and other locations with limited ground access.
Julio Pérez, Operations Manager at Ecocopter by Helisul: "Every Human External Cargo mission requires meticulous planning under strict international aviation regulations. Our Airbus H145 helicopters have become precision tools capable of transforming tasks that previously required several days into operations completed within a few hours, improving working times by around 80 percent compared with conventional methods."
The companies said the introduction of HEC technology positions Chile among the leading Latin American countries applying advanced aerial solutions for the maintenance of critical energy infrastructure. The capability is expected to support the country's expanding transmission network and growing integration of renewable energy sources.
Álvaro González, General Manager of Maintenance at BBosch: "Future transmission systems require innovation, specialized expertise and solutions capable of meeting the demands of increasingly complex infrastructure. This strategic partnership demonstrates how combining aviation experience with high-voltage engineering can establish a new benchmark for the regional energy industry."
Ecocopter by Helisul is a leading helicopter operator in Latin America specializing in aerial work, emergency medical services, offshore transport, utility support, firefighting and other complex aviation missions. Through its integration with Helisul Aviation, the company operates a modern fleet across multiple South American countries, providing specialized helicopter services for government, industrial and commercial customers.
