Met Mast Inspections Combined Ground and Aerial Inspections

Top-to-bottom Visual Inspection

Mech-V offers complete top-to-bottom visual inspection of met masts. Performed by our engineers using state-of-the-art industrial inspection drone technology. UAV inspection is a cost-effective, safe and proven way to ensure the integrity of your met mast structures. This applies both in service and ahead of any planned maintenance activity where climbing is required.

Cost-effective and Safe

Our experienced engineers can identify any construction defects or safety concerns. We are aware these assets can often suffer from significant structural or safety-critical defects. Aerial and field inspections are one of the most cost-effective and safe ways to identify serious construction errors or degradation of components. As an Irish-based inspection services company, Mech-V can be responsive to support clients across Ireland to help them safeguard the integrity of their assets.

We are certified to the internationally recognised Global Wind Organisation standards.

Fully Insured

We hold 13m employers liability insurance and 6.5m public & products liability Insurance.

Experienced Engineers

We are wind industry-experienced engineers with strong technical backgrounds.

Common Inspection Areas and Issues

We inspect all types of met masts whether they are temporary or permanent. Faults detected are not only from long-term weathering in operation but more often than not from initial construction defects. This is why it is important to also consider early inspections prior to taking control of the asset.

Common defects on new masts

  • Damaged steelwork and components due to poor construction / handling practices
  • Missing structural steelwork
  • Mast sections installed in the incorrect order
  • Incorrect bolts or short bolts installed
  • Bolts missing washers or other anti-loosening measures
  • Incorrect fixings (Galvo coated or stainless steel used where it shouldn’t be)
  • Short foundation anchor bolts leading to deviations on bolted fixings.
  • Inadequate drainage considerations
  • Missing or poorly installed anti-climb measures
  • Missing safety signage
  • Poorly routed and affixed cabling

Common defects on operational masts

  • Construction defects as previously mentioned.
  • Missing or loose bolts
  • Defective or corroded fall arrest system, ladders, mounting brackets and pegs
  • Corroded foundation anchors and anchor bolts
  • Loose or damaged cabling
  • Corroded instrumentation cabinets
  • Missing anti-climb protection
  • Corroded steelwork, structural members, welds, U-bolt clamps and instrument booms
  • Defective anemometry
  • Corroded guy wires and D-rings
  • Damaged solar panels
  • Missing or failed lightning finial
  • Missing or faded safety signage
  • Drainage issues resulting in water logging and accelerated corrosion at foundation
  • Missing or corroded earths

Post-Construction (Newly Installed Masts)

We offer inspection of newly installed met masts to make sure they are constructed to the designer’s specification and that the quality of workmanship is up to the expected standards. A quick inspection can identify any construction defects that will affect the safety of your asset and also its lifespan.

Post-construction inspection is a quick and low-cost activity to perform. One inspection will allow you to confirm that your asset has been constructed to specification, is safe to the public and will achieve its intended life expectancy. Capturing and recording information on any construction defects early on will allow you to effectively challenge your installation contractor and so reducing your costs.

Operational Masts

It is important to perform inspections of your met masts' assets on a routine basis. This is to ensure they are structurally safe for maintenance personnel and the public. This is even more important when working at height maintenance activity is being planned and personnel will be climbing the structure. A pre-climb drone inspection can not only identify any safety concerns but also be used to pre-order the materials which will be needed for any repair activity. This not only reduces the risk to the maintenance teams but also the overall cost.

Met mast structures are exposed to harsh weather conditions in long-term operation and tend not to receive the same maintenance attention as revenue-producing assets do. Structural failures and weaknesses are therefore commonly observed. To counter these issues field inspections using drones are a proven low-cost, low-cost way to help gather vital information to help prioritise and plan maintenance activities.

Our Drone Capability

We fly cutting-edge DJI enterprise-level inspection drones. These drones are capable of safely inspecting high-value assets at a stand-off range. This is due to their stabilised optically zoomed high-resolution cameras. They also feature a thermal camera to see what the naked eye cannot.

  • 20 MP Camera with stabilised 23x optical zoom
  • 12 MP Wide Camera
  • 1200m Laser range finder
  • 640×512px Radiometric Thermal Camera
