Inspection & Energy

Pipeline & rail corridor inspection

Inspect defined route assets and record defects or changes along them.

Discuss this service

What you receive

  • Chainage/asset-linked image and defect register
  • ROW and encroachment observations
  • Optional clearance model or internal CCTV records
  • Maintenance-review dataset and coverage report
How we deliver

Scope & options

Corridor inspection records condition against chainage/asset ID so observations can be acted on in the owner’s maintenance system.

Aerial ROW observation does not measure buried-pipe wall condition; internal pipe work needs separate robotic/NDT methods.

Rail clearance, track geometry and rail-flaw testing are distinct calibrated disciplines.

Explore 5 service variants

Pipeline ROW and exposed-asset inspection

Observe exposures, crossings and visible route changes.

External imagery does not determine buried-pipe wall integrity.

Railway OHE, structure and clearance inspection

Record railway assets and specified clearances.

Railway access and traffic/electrical protection are mandatory project inputs.

Robotic CCTV sewer and pipeline inspection

Inspect accessible internal pipe surfaces with crawlers/cameras.

Separate ground-robotic scope, cleaning/access controls and competent defect interpretation.

Road asset and pavement-condition monitoring

Document road assets and specified pavement observations.

Calibrated roughness/rutting tests need a suitable specialist system.

Methane/LDAR follow-up

Investigate suspected gas leaks with gas-specific sensing.

Gas-specific sensing can flag suspected emissions; a leak-rate claim requires a separately validated quantification method.

Useful to know

Terms, explained
Right of way (ROW)
The corridor within which pipeline, rail or related assets and encroachments are assessed.
Route condition
Visible asset, terrain, vegetation and access changes recorded along the corridor.
Clearance survey
Measured space between rail/pipeline infrastructure and nearby structures or obstacles where required.
Can aerial imagery prove a buried pipeline is sound?

It can show route conditions and visible exposure. Internal condition, corrosion and wall thickness need the appropriate inspection/testing methods.

Does railway imagery certify track geometry or detect internal rail flaws?

Those require specified measurement and testing systems beyond ordinary aerial inspection.

Can the service include sewers and water pipes?

Yes as a defined in the agreed scope robotic CCTV inspection through a suitable partner, with access and safety arrangements confirmed.

Can a route inspection run beyond visual line of sight automatically?

Route length, automation or a dock does not create operating permission. The partner must establish the applicable lawful operating basis.

Method & limitations

Choose the asset and failure question before selecting an inspection method.

Reference findings by chainage, asset ID and observation date.

Keep external observation, internal pipe inspection and calibrated rail/road tests distinct.

External imagery does not determine buried-pipe wall integrity.

Railway access and traffic/electrical protection are mandatory project inputs.

Separate ground-robotic scope, cleaning/access controls and competent defect interpretation.

Calibrated roughness/rutting tests need a suitable specialist system.

Gas-specific sensing can flag suspected emissions; a leak-rate claim requires a separately validated quantification method.

Help me ask
  • Is the concern route encroachment, external damage or internal pipe condition?
  • What chainage and asset-reference system should the report use?
  • Which railway or utility access controls must be arranged?
Use ordinary words. A short problem description is enough. Do not include confidential or security-sensitive information.
Start with state and district/city. Exact boundaries can be provided later through an agreed channel.Leave blank if unknown.
An estimate is acceptable. Leave unknown rather than inventing a measurement.Leave blank if unknown.
This is a preference, not a confirmed mobilisation or delivery date.Leave blank if unknown.
Personal addresses are accepted for civilian enquiries and individual training.
More project detail Optional
State only a non-sensitive reference. A submitted standard is a requirement to review, not a claim of accreditation.
Examples: ground-only work, no cloud hosting, limited access. Do not include personal IDs, confidential documents or sensitive locations.
Which outputs do you need?
Optional: choose outputs within the approved scope, or leave undecided. This is a request, not automatic inclusion.
Optional specialist variants
Only independently verified variants may be selected for a commercial enquiry.
