Every outage hour is a megawatt-hour you don’t sell, and every confined-space entry is a person somewhere they shouldn’t have to be. The Scout 137 flies the hydro and thermal assets that traditionally need dewatering, rope teams or an internal scaffold tower, and brings out a complete, location-tagged record your integrity team can rely on, before the unit comes back online.
Where Scout 137 flies
Dewatered penstocks, headrace tunnels and surge shafts, plus spillway chutes, radial gates and stilling basins. Liner and coating condition, concrete spalling and cavitation in a single flight, no rope team or diver.
Boiler tubes, furnace walls, superheater and heat-recovery banks, headers and drums. Internal corrosion, erosion and wall thickness during the outage. No staging tower inside the firebox.
Monopile interiors, transition pieces and jacket cells, confined spaces tens of metres from the access hatch, captured in single flights.
Flue stacks, chimneys, ducting and precipitator internals. Lining, refractory and corrosion under deposits, without erecting an internal scaffold.
The challenge today
Days → hours
A drone flight replaces the scaffold tower that takes days to erect before inspection can even begin.
Up to 90%
Lower inspection cost than scaffold-and-rope access. The access bill disappears with the scaffolding.
Zero
Confined-space entries when the drone records the evidence instead of a person.
One visit
Visual, thickness and 3D captured in a single outage window, before the unit comes back online.
In hydro the cost is in megawatt-hours; in thermal it’s in firebox days. Scout 137 shortens the outage and takes the human out of the asset on both.
How Scout 137 changes it
Three capture streams from one tethered drone, assembled in Scout Portal into a complete record your integrity team can rely on.
See
Concrete cracking, liner pitting, tube-wall erosion, weld condition and coating defects at survey detail. The reviewer sees exactly what the inspector saw.
ExploreMeasure
Ultrasonic thickness with built-in surface prep and couplant. The surface is cleaned and measured in the same pass, each reading pinned to its position on the 3D model.
ExploreContinuous flammable-gas monitoring on every flight: 14 flammable gases including methane, propane, and ethylene. Two-tier LEL alerts logged with flight data; a safety supplement, not a substitute for confined-space clearance.
ExploreThe modular payload bay is built to grow. We won't spoil what's next, but we listen to what the industry whispers about. Got an inspection problem we should solve?
Locate
A survey-grade 3D model of penstocks, draft tubes and boiler volumes, every defect tagged to its exact position in the asset.
ExploreEvery flight exports a survey-grade point cloud of the asset interior, flight path included. Drop it straight into digital twins, BIM workflows, CAD models, and as-built documentation.
ExploreLooking ahead
Everything that makes the Scout 137 work in a penstock or a boiler matters even more where exposure is the real budget: a remote, no-entry inspection that keeps people out of the space. A natural next step for the platform.
What the platform brings
A record you can trust
Every capture is time-stamped and pinned to its position in a 3D model, assembled in Scout Portal into one complete, repeatable record, validated live on site, so findings are confirmed before you leave. It supports the way your power assets are reviewed and signed off.
As featured by Microsoft
Ørsted, the world’s largest offshore wind developer, chose Scout 137 to inspect inside its turbine foundations. Microsoft, Ørsted and Cognite showed how the data flows through the Scout Portal API into Cognite Data Fusion for predictive maintenance, with the crew cut from 4 to 2 persons and kept clear of the confined space.

Field record
“This collaboration demonstrates how advanced robotics, autonomy and digital analysis can converge to meet the inspection needs of long-lifespan, high-risk infrastructure assets such as dams.”
From the Storfinnforsen case KIWA for Uniper
50% more coverage per flight 40+ workdays saved vs manual methods

Proof from the field
A practical look at how tethered drone inspections deliver consistent data, reduce downtime, and remove the need for manual entry.
At Storfinnforsen, KIWA used the Scout 137 to capture 300,000 images across the dam surfaces for Uniper. Spotscale turned the dataset into a navigable 3D model with every crack detected and measurable — about 50% more coverage per flight and an estimated 40 workdays saved compared to manual, scaffolding-based inspection.
Cargo holds, ballast tanks, FPSOs, turbine foundations. Inspection without entry, output ready for class survey.
Explore →Refineries, storage tanks, pressure vessels, columns. Land-based process facilities. Visual plus UT, in one flight.
Explore →Active shafts, stopes, abandoned workings. Proven at 400 m mine depth.
Explore →Tunnels, reservoirs, dams, sewers, water systems. Confined and constrained civil assets, captured cleanly.
Explore →DNV, Bureau Veritas, LR, ABS, and API workflows. Inspection output that passes class review across marine, energy, and asset integrity.
