Drone may check water tower

By KEVIN R. JENKINS

In the past, the city of Desloge has hired a person to take the ladder to the top of the city’s 130-foot water tower to perform an inspection, but now it’s considering using a drone to check a filter on the tank that needs to be replaced periodically.

When the city of Desloge begins to check out the condition of its 130-foot municipal water tower, rather than using a human being to climb the ladder, a drone may be used to perform an inspection of a filter.

“There’s a filter on top of the tower itself that needs to be inspected on a periodic basis,” he said. “In the past we’ve sent a man up the ladder to the top of the water tower to inspect that filter. We explored the idea of maybe using technology we weren’t able to do five or 10 years ago, but we’re able to do now.

“We’re considering the option of sending a drone up there to make a video and visibly inspect the filter that way and see if we can get good and clear footage to make a decision rather than sending someone up the side of the water tower on the ladder to visually inspect it in person.”

Drones Speed Solar and Wind Farm Inspection

By  , Executive Editor, on 

Duke Energy is using small unmanned aerial systems to inspect several different types of assets in its portfolio. Use of the drones has had a tremendous impact on regular inspections of photovoltaic panels and wind turbines.

Duke Energy is the largest electric company in the U.S., delivering electricity to about 7 million customers in the Southeast and Midwest. More and more of that electricity is being generated by renewable technologies. The utility owns more than 1,700 MW of generating capacity through 15 wind farms and 17 solar farms in 12 states.

Inspecting all those assets can be a daunting task, however, taking a few days to walk through just one 5 MW solar field, for example; or having to repel with ropes from a wind turbine hundreds of feet in the air to inspect blades.

When Duke Energy initiated a drone project in August 2014, the utility had augmented safety and improved operational excellence in mind for all its assets. Though Duke’s first pilot project was at its Marshall steam plant in August 2015, early interest in the use of the small unmanned aerial system (sUAS) came particularly from the utility’s commercial renewables group for inspecting solar and wind farms. Duke’s first solar farm inspection was in February 2016, with the first wind farm inspection coming a month later. By summer of 2016, more solar farm inspections were being added to the rotation, and Duke now has about 30 sUASs in operation.

Drones trialled for the inspection of large railway structures

The LNE&EM route Structures asset management team is trialling the use of unmanned aerial vehicles (UAVs) to inspect large structures in a safer and more cost efficient way.

The vehicles, commonly known as drones, are being used to get a closer look at five arch viaducts on the route, including the Grade 1 listed, 28-span Royal Border Bridge in Berwick-upon-Tweed, Northumberland (UK).
