What We Do - Powerline Patrol

When it comes to transmission power lines, reliability is the name of the game. With the ever growing Federal Energy Regulatory Commission (FERC) Regulations and Standards and North American Reliability Corporation (NERC) Compliance issues for electric power lines, aerial patrols are becoming more popular among electric utilities. Whether it is inspecting the condition of the infrastructure or finding those “danger trees” that can cost utilities millions of dollars in repair and/or outages, we can customize our patrols to fit customer needs and budget. Aerial patrols play an integral part of a utility’s Vegetation Management Program by gathering the necessary data to implement an effective plan to prevent a contact and maintain proper clearances. After witnessing other utilities pay steep penalties and litigation related to “critical line contacts,” more and more electric utilities are realizing the benefits of preventative right-of-way maintenance and aerial inspections.

Fixed-Wing Patrols
Patrolling power lines with fixed-wing aircraft is an efficient way to detect general discrepancies in the condition of the infrastructure. Pilots can observe broken arm braces, dislodged static lines, general structure condition, and danger trees. This is a fast and low cost way to inspect the general condition of the right-of-way.

Rotor-Wing Patrols
Nothing matches the capability, versatility and cost benefit of using helicopters to patrol power lines. A very detailed and comprehensive inspection of every single structure can be obtained using our helicopters. Hawkeye Helicopter deploys a proven inspection technique in which the helicopter hovers as near each structure as practically possible as safety allows, while experienced power line personnel inspect the infrastructure by viewing through digitally-stabilized binoculars. Many utilities have found that conducting infrastructure inspections from a helicopter can be accomplished without the use of binoculars and proven to be more thorough and cost effective than ground based inspections.

Items that can be inspected through this method include:

  • Static/Phase Line Saddle Pins
  • Loose Bolts/Nuts
  • Tree Clearance
  • Ground Wire Connections
  • Woodpecker Holes
  • Insulator Condition
  • Shield/Phase Line Lightning Strikes

Whether you require a slow fly-by or a detailed hover inspection, Hawkeye’s signature services will meet the need.

Hawkeye Helicopter’s relationships with other technical and professional service providers, allows us to assist utilities in conducting infrared inspections, corona inspections, LiDAR and GIS data acquisition, preliminary route studies, design services and legal boundary issues regarding survey matters.
