Implementing LiDAR in Pipeline Surveys Expands Project Scope Capabilities for MSI
Company: Measurement Sciences Inc.
Measurement Sciences Inc. is a Calgary based professional engineering and land surveying company founded in 2005. MSI ‘s team of engineers, land surveyors, and technicians use the latest technology to provide solutions to a broad base of clients. Clients include oil and gas pipeline companies, land developers, power generation, engineering, and construction firms, as well as local municipalities and provincial governments.
Up in Canada, MSI is faced with a wide array of challenges including a very small window of fair-weather surveying, from May to October, to collect a significant number of river-crossing surveys and pipeline surveys. The narrow weather window combined with a high project site count demands a solution capable of mapping large vegetated areas efficiently in order to meet deadlines. Boots on the ground topographic surveys weren’t cutting it.
MSI, Inc. leverages lidar technology in the oil and gas industry by expanding their project scopes and increasing the number of completed surveys within the short fair-weather window between snowmelt to snowfall.
They implement lidar in pipeline surveys to be able to show a grander scope of the river crossing and banks. LiDAR enables their team to produce a much more detailed pipeline profile than traditional methods (i.e. taking gridded shots every 5 meters with GNSS), and offers expanded client deliverable offerings.
The [Phoenix] LiDAR systems have allowed us to expand our scope, as well as, get bigger and better detail for our surveys. The LiDAR allows us to meet deadlines by mass collecting.”
MSI realized the potential for high resolution change detection analysis with the increase in data density. Previously, they did surface-to-surface change detection from gridded topographic surveys. Now, they leverage the high density lidar to perform point to-point surface differencing and have found the high quality resolution and accuracy of these lidar pointclouds make it possible to detect small amounts of change. This enhanced representation of site change is paramount for pipeline monitoring.
The team at MSI uses Phoenix LiDAR systems to detect small topographical changes on the order of 5 cms - an impressive feat taking the densely vegetated site characteristics into consideration.
MSI, Inc. owns and operates three Phoenix LiDAR systems: the MiniRANGER-1, RANGER-LR, and RANGER-XL. Their best collection windows are early spring and late fall, so they try to group as many sites together as possible to map consecutively during two sizeable RANGER-XL helicopter campaigns each year. They deploy the UAS-based miniRANGER to supplement sites between those two collection windows. This keeps the cost of helicopter operations down and still enables MSI to collect sites on demand, if needed, rather than waiting for the two seasonal windows. The decision process for which Phoenix system to deploy varies site by site - depending on time of year, project scope, and strictness of deliverable timelines.
