Remote Monitoring

NVI’s exclusive solution for North America is the deployment of real-time monitoring systems designed by A3 Monitoring. The remote monitoring packages are true turnkey, noninvasive solutions geared at achieving regulatory compliance and extending the life of the asset. Remote monitoring technologies are unmatched in providing value over the life of the asset which, in turn, are often the lowest cost solution. Each package is scalable and starts with a base communications system in which ‘plug and play’ are added inspection technologies. Unlike other technologies available on the market, multi-method monitoring is achievable without the added cost of additional communication units at the same monitoring location. Ultrasonic monitoring (UT) can be paired with acoustic emissions (AE) and cathodic protection (CP) technologies all in the same installation and with a single communication unit and shared software resulting in lower overall installation and ongoing monitoring costs. Monitoring communications are also customizable according to the best available technology per installation sites such as satellite (Iridium), GSM, UMTS, LTE, or fixed site data logging.

Acoustic Emission Remote Monitoring

Acoustic Emission (AE) is the MOST flexible NDT method. NVI utilizes AE monitoring structures. This technology can is used for monitoring the ‘acoustic activity’ generated while hitting the pipe both accidental (digger hitting pipe) and intentional (theft attempt). Third-party interference equipped with appropriate alarms are sent to the asset owner or pipeline operator.

AE enables to monitor pipeline for identification of:

Cracks: Utilizing Acoustic Emission, you can detect noise/emission of cracks growing, and other active damages in pressure vessels, tanks, and piping systems.

Leaks: AE is an excellent tool for detecting and locating leaks in buried and liquid-filled pipelines. It is required to have access to the pipe to mount AE sensors. The AE sensors detect the turbulent flow at the leak orifice, and with the use of digital acoustic emission systems and specialized software, the position of the leak appears.

Corrosion: Different types of corrosive processes can be detected using Acoustic Emission, including stress-corrosion cracking, pitting, crevice, corrosion, and inter-crystalline corrosion.

Acoustic Emission detects any noise produced along a pipeline.

Some advantages include:

  • Accuracy: Detects leaks quickly and issues no false alarms
  • Accessible everywhere
  • Robust: Withstands harsh environments and can be buried or submerged
  • Cost-Effective: Retrofit only at specific locations and long range
  • Reliability: Use sensors with high reliability and low-maintenance
Cathodic Protection Remote Monitoring

NVI utilizes Cathodic Protection (CP) Remote Monitoring to identify external threats with a sudden change of voltage due to coating damages. By using CP remote monitoring, NVI can detect when and where third-party damage or illegal derivation has happened. If a value exceeds the user’s threshold, Cathodic Protection monitoring will immediately check voltage and alarm. Cathodic Protection Remote Monitoring communicates using mobile, satellite, or wifi. Automatically stored Data is accessible at any time via the internet.

CP enables to monitor pipelines and other assets for:

  • Cathodic protection levels: enables to verify compliance with existing standards and regulations easily
  • CP variations due to changes to soil conditions: can monitor soil moisture allowing to correlate changes in CP readings to changes in soil resistivity
  • AC interference on pipelines: reduce risk of unexpected failures due to AC interference by continuously monitoring the pipeline

spotOn CP advantages:

  • Accurate: Detects small DC and AC voltage. Remotely configurable data collection rate to track fast-evolving events
  • Works Everywhere: Cellular, WirelessHart, satellite link or data logger
  • Robust: Withstands harsh environments and surge protected against lightning
  • Cost Effective: one-time access and no need for additional IT investment
  • Reliability: Use sensors with high security and low maintenance


Long Range Remote Monitoring

NVI’s corrosion monitoring solution, spotOn Guided Long Range, leverages on an innovative patented technology providing remote threat identification for pipes that are difficult or expensive to access. This technique can access difficult areas to identify internal and external corrosion threats in pipelines. Excellent flexibility and high performance are achievable utilizing Guided Long Range monitoring. Compared to screening, AUTO LR software improved detection capabilities.

Where is Guided Long Range Remote Monitoring?

  • Bare Pipes
  • Under Insulation
  • Road Crossings
  • Buried pipes where threat areas may be large
  • Under Repair
  • Large Subsea Sections

Some advantages include:

  • Safety: Non-intrusive operation and minimum access risk
  • Robust: Outside carcass made of stainless steel and withstands harsh environments and can be buried or submerged
  • Flexible: Normal cable exit radial, axial exit also possible to place within confined space, and re-position transducer
  • Cost-Effective: Long range, and retrofit only at specific locations
  • Accessible everywhere
Ultrasonic Thickness Remote Monitoring

NVI utilizes a permanently-installed real-time corrosion monitoring solution called spotOn U (Ultrasonic Thickness Monitoring). This type of technology is designed to operate in most environments and locations such as offshore, above ground, and below ground.

Some advantages include:

  • Safety: Non-intrusive operation and minimum access risk
  • Robust: Withstands harsh environments and can be buried or submerged
  • Simplicity: Ease of installation, fully automatic software configuration and network connection, and works with existing IT systems
  • Accuracy: Wall thickness and corrosion and remotely configurable data collection rate to track fast-evolving events and test corrosion
  • Cost-Effective: One-time access to challenging locations as well as no need for additional IT investments
  • Accessible everywhere
  • Real-time: Data is available in real-time, custom thresholds can be defined, and warnings are dispatched automatically, and remotely configurable to track fast-evolving events and test corrosion inhibitors
  • Reliable: Automated sensing for minimal measurement error, continuously self-checking, and remotely configurable to maximize battery life.
Sand Monitoring

Monitoring sand in production wells is exceptionally crucial. Sand can cause clogging of the production equipment as well as significant safety/integrity issues due to the erosion of the pipes. NVI has the perfect solution for sand monitoring whereby changes in sand production over time is detected using spotOn AE, and the erosion caused by the produced sand is monitored using spotOn U.

The integrated spotOn AE + U provides you with many advantages:

  • Data coming from sand flow is directly correlated to erosion data using the same software
  • spotOn AE + U can send data via satellite and Wireless Hart
  • Clients can enjoy significant savings in infrastructure due to the two sensors attached to the same comms unit
  • Clients can enjoy further savings in training due to all data displayed on the same user-friendly shieldCube software platform.

Other advantages include:

  • Accurate Sand Monitoring: Thickness monitoring and false calls avoided
  • Works Everywhere: WirelessHart or satellite link
  • Robust: Withstands harsh environments, and can be buried
  • Cost Effective: Retrofit only at specific location
  • Real-time: Data is available in real-time without user intervention and warnings are dispatched automatically

spotOn AE + U detects sand flow and erosion:

  • AE identifies sand particles hitting the pipe
  • U verifies the thickness at key locations
  • AE and U data are correlated to alert of flow changes causing integrity issues
