A New Dawn in Natural Gas Detection

LASEN has surveyed more than 500,000 miles of pipeline, and detected over 40,000 pipeline leak indications with an industry leading accuracy rate.

Using LASEN's airborne technology has saved our customers millions of dollars.

Latest Technology

Our systems are equipped with the latest high resolution imaging cameras, GPS receivers, and Lidar sensors, with an industry leading 1,600 square ft. footprint on the ground, making it possible to precisely locate hydrocarbon leaks.

Aspen Avionics

We have now integrated Aspen systems into our helicopters that give us real time data on wind direction and speed. With the Aspen system we can fly with precision accuracy directly above the pipeline.

PipeVision™

The new ALPIS™ units employ our new PipeVision™ video camera that provides high resolution video of more than 800 feet of your right of way at their widest angle and is tied to continuous GPS location.

Quick Turnaround - Online Access

Inspection reports are available by 8:00 AM the very next morning. Inspection data can be available within 1 to 2 hours of an inspection with proper notification.

GPS Data & Flight Imagery

Download GPS coordinates, images from the helicopter, and satellite imagery of the location for each indication to allow for easy location of the site.

Federal Regulations: Transmission/Distribution

§ 192.705 - Transmission lines: Patrolling

Each operator shall have a patrol program to observe surface conditions on and adjacent to the transmission line right-of-way for indications of leaks, construction activity, and other factors affecting safety and operation.

§ 192.706 - Transmission lines: Leakage surveys

Leakage surveys of a transmission line must be conducted at intervals not exceeding 15 months, but at least once each calendar year.

View Regulations

§ 192.721 - Distribution systems: Patrolling

Leakage surveys of a distribution systems must be conducted at intervals not exceeding 7 1/2 months, but at least twice each calendar year

§ 192.723 - Distribution systems: Leakage surveys

A leakage survey with leak detector equipment must be conducted in business districts ... at intervals not exceeding 15 months, but at least once each calendar year. A leakage survey with leak detector equipment must be conducted outside business districts ... at least once every 5 calendar years at intervals not exceeding 63 months.

Superior Airborne Pipeline Leak Detection Survey Contractor

DOT/PH MSA funded LaSen, Inc. to develop and ultimately offer the best solution for leak detection and video surveying of storage fields, gathering and transmission gas and liquid pipeline systems with unmatched accuracy, speed, report turnaround time (within hours), all for a reasonable price. By consistently meeting these objectives, we have earned many major pipeline company’s repeat business throughout the USA’s lower 48 and in Canada. With our helicopters in different parts of the US, we can quickly work your pipeline survey needs and compliance dates into our existing flight (inspection) schedule. Thus our shared mobilization plan greatly reduces the cost.

Unmatched Flying Altitude

300-500ft, safely above trees and power lines

Unmatched Flight Speed

Our system can operate @ 60 mph

Unmatched Laser Speed

Laser @ 400 hertz, more than double our competitor's

Laser Illumination

1,600 square feet that illuminates ROW 400 times per second

Unmatched Detection Accuracy

Capable of detecting the smallest leaks down to 5 PPM

Aspen System

Real time data on wind speed and direction

ALPIS is a stand-off detection system. Leak indications are detected when the eye-safe laser beam passes through a plume of methane or NGL: propane, butane or other hydro-carbons.

The laser is tuned to only detect one hydrocarbon during the survey.

The laser is synchronized with the downward looking camera and records both the GPS coordinates and a photograph of each leak indication detected.

Video of your ROW is filmed from our helicopter pilot’s view to see: Encroachments, Erosion, New Structures, Tree Canopy, Construction Inspection, Damages, etc.

The video is date and time stamped to prove when your ROW was both leak and visually surveyed.

ALPIS™ - Airborne Lidar Pipeline Inspection Service

ALPIS™ System Components

ALPIS™ is comprised of an airborne sensor unit and operator’s console.
The main sensor enclosure houses the eye-safe laser, computer, receiver optics and detectors.
In addition, the system is equipped with a high resolution imaging cameras and a GPS receiver.

How It Works

The eye-safe laser beam is transmitted down from the aircraft to illuminate the area on the ground above and around the buried pipe.
The light reflected from the ground is collected by the sensor’s receiver, and the amount of received energy is measured.
If the eye-safe laser beam passes through a gas plume emanating from a pipeline leak, the received energy will be diminished due to the absorption of laser light in the plume.
This absorption signature is used to locate the leak and to assess its approximate magnitude.
