Corridor survey for cross-country pipelines · encroachment, vegetation, terrain change and depth of cover.
A right-of-way changes; the pipeline does not move. We fly the corridor, classify what has appeared on it since the last survey, and return an encroachment register, a quantified terrain change model and a class location review your integrity team can act on.
Because the corridor changes and the pipeline does not move. A right-of-way cleared and documented at commissioning is, a decade later, carrying unauthorised structures, farm access tracks, irrigation channels, road and rail crossings built after the fact, and vegetation that has grown back into the patrol corridor. Third-party interference remains among the leading causes of pipeline incidents worldwide, and almost all of it begins with something appearing on the right-of-way that the operator did not know was there.
The second driver is the ground itself. River crossings scour, slopes creep, mining and groundwater extraction cause subsidence, and each of those changes the depth of cover and the strain on the line. A foot patrol records what a walker noticed on the day. A LiDAR survey records the entire corridor as a measurable surface, so the question stops being what someone observed and becomes what changed between this survey and the last one, quantified in metres.
Change detection is the point. A single survey is a baseline. The value compounds from the second one.
Chartered Engineer signed deliverables · corridor-wide change detection · routes to the 3D LiDAR practice lead within 24 hours.
Right-of-way alignment, corridor width and buffer agreed against your alignment sheets. Flight lines planned for full corridor coverage with side overlap, and permissions obtained for the airspace and the route. Ground control laid along the corridor at agreed intervals.
Helicopter or fixed-wing UAS LiDAR flown along the alignment, with simultaneous high-resolution imagery for interpretation. Point density set by the deliverable · encroachment detection and vegetation classification need less than depth-of-cover profiling over a critical crossing.
Terrestrial or mobile capture at road, rail and river crossings, at valve stations and at any location where the airborne data is ambiguous or where the deliverable requires higher confidence. Marker and pipeline appurtenance positions verified on the ground.
The cloud is classified into ground, low and high vegetation, buildings, structures and infrastructure. Where a prior survey exists, surfaces are differenced to produce a quantified terrain change model showing scour, subsidence and fill.
Encroachment register with position, class and photographic evidence per item. Vegetation report against your clearance criteria. Depth-of-cover profile along the alignment. Class location review against current population density. Alignment sheets updated to as-surveyed condition.
Deliverables are prepared against the pipeline integrity and geospatial standards your regulator and integrity management system reference. Every deliverable signed by a Chartered Engineer (CEng MIE India).
Three landmark engagements from our verified roster · quantified outcomes, no client names disclosed without written permission.
Full corridor flown and classified against the operator's clearance criteria. The encroachment register returned a substantial number of structures within the right-of-way that had not appeared in patrol records, prioritised by proximity to the line for the integrity team.
Repeat survey differenced against a baseline flown two years earlier. Terrain differencing quantified bed scour at a major crossing and identified reduced cover over a defined chainage band, which moved the section into the operator's near-term intervention programme.
Corridor survey combined with current structure counts to review class location along a segment that had urbanised since commissioning. The review identified reaches where the class had shifted, with the implications documented for the operator's integrity plan.
