Preventing Pipeline Intrusion

Empowering one of India’s largest Oil & Gas providers to ensure maximum safety by leveraging existing infrastructure to monitor and prevent third-party intrusions, along a 73 km pipeline.


As one of India's largest Oil & Gas providers, this company bears a massive responsibility when it comes to ensuring the transportation of pipeline contents safely and efficiently. However, the topography posed a major challenge.

We partnered with Fotech Solutions to deploy 'HELIOS' - a highly advanced intrusion detection system. By means of Distributed Acoustic Sensing, it was possible to monitor and protect the entire length of the pipeline from a single location.

The Task

In this age of 24×7 monitoring and surveillance, securing every inch of a hazardous cross-country pipeline infrastructure manually is not an economical solution. One of our foremost customers realized this and sought the technological intervention needed to meet safety and security objectives.

The project objective involved the installation of an optical fibre-based Pipeline Intrusion Detection System for monitoring any kind of third-party intrusions along the 73 km stretch of pipeline. The system also required setting up an early-warning system that could equip the customer with the ability to immediately respond to potential intrusions, thus preventing pipeline damages.

Integration of Sensors and Control Systems with existing SCADA and CCTV systems for effective and real-time monitoring was an integral part of the project. We also had to build a basic signature library for typical intrusion activities and allow for the addition of new third-party activities as well.

The Challenge

The critical importance pipelines hold for Oil and Gas companies as well as the need to secure them from damage cannot be underscored. There exists a major threat of pilferage, which not only causes substantial financial losses to pipeline operators, but also poses a huge risk to life, property, and the environment.

Conventional security solutions like CCTV, IR, or ultrasound sensors are not feasible for monitoring pipelines that span hundreds of kilometres in length.

We faced a multitude of challenging situations, right from tracing the actual position of the pipeline along the entire route; passing through widely varying terrain of farms, villages, towns, industrial areas and uninhabited areas.

Implementation of Distributed Acoustic Sensing technology for Pipeline Intrusion Detection, which is a new vertical for pipeline safety and security in Indian conditions, was a challenging feat.

The exact type of intrusion (for example manual digging, mechanical excavation, etc.) had to be identified. This task becomes even more exhaustive when there are multiple simultaneous intrusions. This is further complicated by the presence of background environmental noise that would overwhelm the location capabilities of regular sensors. Thus, we needed to employ special sensors that utilized advanced optoacoustic engineering expertise.

Furthermore, the intrusion detection system had to be seamlessly integrated with the existing command and control system and security set-up. Alarms were to be transmitted through a variety of means to multiple responders, in order to ensure rapid action in case of a real threat. It was also necessary to prevent false alarms triggered by benign activities occurring further away, like irrigation and construction.

The Solution

Delivering a full range of end-to-end PIDS solutions using existing OFC required thorough analysis and testing, with a detailed execution roadmap through one of the most demanding sites.

A distinctive feature of the solution is that the PIDS instrument is located in the control room and requires no installation or power in the field; besides the existing OFC. Hence, just by harnessing certain unique properties of the telecom optical fibre cable running along the pipeline, the distributed sensing system was able to detect, accurately locate and even identify any intrusion attempt along the entire monitored length in real-time.

In pursuit of locating the exact positioning of the OFC, the entire route was divided into various zones for identification and singularity with a minimum width of 0.6 meters. By carefully calibrating the system at multiple sites under varying operating conditions, a new acoustic stream was generated which could distinguish pipeline vibration during high flow rates from actual third-party interferences.

The system architecture consisted of a PIDS server with RAID 5 configuration and 1 Helios controller for the pipeline at a central station. The controller being a two-channel system, enabled pipeline monitoring in both directions of the central station. The controller was connected to the server via an Ethernet link, with two client workstations at opposite ends, enabling sequential monitoring of two sections of the pipeline. The connectivity between the clients and server was established through an Ethernet link extended over the existing pipeline’s telecommunication system.

The system worked on the principle of Distributed Acoustic Sensing, wherein acoustic signals generated by intrusion activities are picked up by the optical probe pulses sent down the OFC. It consists of an interrogator that sends optical pulses from a highly coherent laser and detects back-scattered light.

Each type of intrusion has a distinct “acoustic signature” by which it can be uniquely identified. Using specialized algorithms involving powerful computational techniques, the raw signals are processed to zero-in and precisely identify the type of activity.

Upon detection of an intrusion event, the system generated an alarm in real-time, which indicated the type of intrusion and displayed the exact location of the event with precise GPS coordinates on a map.

A further layer of algorithms was implemented to determine alarm severity so that persistent, threatening events were categorized as critical alarms. These alarms can be viewed on a Graphical User Interface. Finally, alerts are then sent to security personnel over SMS or e-mail so that a rapid response can be initiated.

The Highlights

  • Successful implementation of a new vertical in pipeline intrusion detection system using existing fibre optic cable
  • The pipeline intrusion detection system serves as an Advance Warning System
  • HELIOS security system installed at one end of the pipeline protects 40 to 80 km of sensor cable length by leveraging existing OFC
  • Uniformly distributed fibre optic sensor detects activities before the pipeline is harmed
  • No electronics or power needed in the field hence is intrinsically safe and unobtrusive
  • Simultaneous intrusion detection of multiple events like walking, digging, vehicle movements, etc.
  • Reliable and accurate location (within 10 meters) of the intrusion also identifying the type of event
  • Integration of Intrusion Detection System with existing SCADA and CCTV systems
  • Provisions for alarm forwarding on mobile through SMS and e-mails in real-time

The Benefits

We are ever dedicated to serving our customers with unmatched advanced engineering solutions, often revisiting and reinventing its offerings. We pushed the boundaries of ‘customer first’ by executing the entire project with minimal external guidance when implementing DAS-based intrusion detection technology for the first time.

Understanding the complex system dynamics through prior research and testing and integrating with the existing communication systems saved considerable time and effort.

The Helios software which was completely web-based allowed for remote monitoring on any computer/portable device with a web browser. In addition to real-time visual monitoring, predefined event disturbances automatically sent out notifications so that no important event disturbances go undetected, ultimately securing areas that were previously not under supervision.

The notification consisted of a Google maps display of the pipeline pinpointing the location of the event disturbance, the time, magnitude, and type, negating the importance of physical presence in the event of an intrusion. The entire system was integrated in such a manner that the flow of alarms from PIDS to the CCTV surveillance system greatly enhanced safety and security, reducing dependability on human accuracy and significantly reducing the investment.

Added functionalities included pig-tracking and leak detection. One of the striking features of this detection mode was its ease of use with the provision of adding new signatures to the library for future detection in case of new events/intrusion types.

Monitoring one of India's largest Crude Oil processing terminals

Networking 64 CCTVs and 16 monitoring stations along the western shore of India so as to engineer a green signal in a high-risk ‘Red Zone’


Along the shores of the western coast of India, lies one of the nation's largest Crude Oil processing plants; a hazardous environment with a variety of physical challenges to overcome.

We successfully installed an integrated CCTV network so as to monitor operations in and around the plant, thereby allowing our customer to successfully run operations and prepare for critical emergencies.

The Task

We had been entrusted to set up an integrated Closed Circuit Television (CCTV) network at one of our customer’s most sensitive installations in western India. This particular site is also one of India’s largest Crude Oil processing terminals covering the entire scope of processing on the western shore.

The Challenge

The topography of the site was unmatched and unprecedented. There was the sea on one side and densely forested hills on the other, leaving the site vulnerable to nature’s fury. There was also a potential risk of terrorist threats as well, owing to the geopolitical tensions with neighbouring countries.

Furthermore, conventional equipment or methods could not be used as the environment was hazardous. Thus, effectively covering the expanse of 15 sq km of the terminal area became a formidable task for our design engineers.

The Solution

The plan envisaged the setting up of CCTV’s at 64 locations and 16 monitoring stations. One of the major tasks that we accomplished was powering all the switches, servers, and remote cameras through a central UPS, which included massive cable sizing calculations.

We installed different types of CCTV cameras at critical locations, an endeavour that required meticulous planning and foresight. Among the different types of cameras, the Explosion-proof cameras were the ones that needed special care as they were heavy (35 kg each) and needed to be installed several meters above the ground, in high-risk zones called ‘red zones’.

Red zones are extremely hazardous zones where the use of any kind of welding or cutting tool was a big risk. Our engineers figured that the best way to erect pillars and mount cameras on top of them, using special fixtures.

The Highlights

  • We installed and commissioned a Dedicated Gigabit Ethernet optical fiber-based telecommunication system along with CCTV cameras.
  • For centralised monitoring of CCTV cameras, Video Management System (Directory) and Network Video Recording System (Archiver) was provided. This enabled remote monitoring, control, and recording of CCTV camera equipment.
  • The unique network topology consisted of five remote locations and one main central station, connected together in a point-to-multipoint configuration.
  • The surveillance system based on Gigabit Ethernet Optical Switches acted as a transport backbone.

Enabling a global EPC to prevail over harsh marine environments

Our Case Studies

Connecting an offshore facility

Enabling a global EPC to prevail over harsh marine environments by installing a communication system at their offshore plant with no compromise on quality or safety.


This offshore facility, owned by a global EPC covers a platform that processes outputs from a large number of production platforms, carried by submarine pipelines, as well as an adjacent platform that encompasses the living quarters housing 70 people.

We provided a comprehensive communication system fitted with voice, video and data transmission capabilities that prevailed over the harsh marine environment.

The Task

Partnering with yet another global EPC, we were entrusted with equipping their offshore process platform, and its living quarters, with an advanced digital telecommunication system for one of their long-time customers. The entire system was engineered for a life span of 25 years under offshore conditions. Considering the stringent emergency communication objectives to be met, there needed to be two independent means of communication. Thus, even if one system were to undergo complete failure, the objectives wouldn’t be compromised.

The Emergency Control Centre (ECC), which is responsible for managing emergencies, disseminating warning messages in case of danger, signaling assembly at muster stations, and managing abandonment of installation, depended heavily on a reliable internal communication system for reaching all personnel on board and coordinating the muster stations, emergency response teams, emergency crane operators, and the infirmary. The communication system enabled full radio coverage so that personnel working anywhere in the facility could be contacted. It also required facilities for paging and party intercom, data and crane operator communications, phone and data communication facilities for operational and administrative functions as well.

The Challenge

As with any offshore installation, there were a unique set of extreme requirements, both in terms of design and execution, to be met. The communication system had to service not only the platform and living areas during normal operating conditions but also the lifeboats and survival crafts during emergencies and disasters; all with exceptional reliability.

All telecommunications systems and equipment had to be operational in hot, humid, corrosive, extremely saline and hostile marine environments. This meant ambient temperatures ranging from 16 C to 40 C, with 100% relative humidity and wind speeds upto 49 km/hr. Additional ingress protection was required for equipment installed in areas vulnerable to sea-water spray or deluge. Furthermore, due to the presence of explosive vapours, all outdoor electrical equipments were to be designed for operation in Zone-1 hazardous environments.

A project of this size and complexity required extraordinary engineering expertise. Co-ordination with the EPC and consultants occurred at multiple levels, with a high degree of detailed engineering down to the design of the minutest of accessories for phenomenal execution at the offshore construction yard.

Apart from keeping in line with the constant modifications in the construction layout, our engineers played a crucial role in determining the most suitable telecom solutions. Assembling the entire system at one point required well-coordinated logistics for timely transportation of equipment and components from various suppliers spread across the globe.

The Solution

The multi-systems solution for a vast critical facility with wells that are expected to produce 5.57 million metric tonnes of oil, 0.75 million metric tonnes of condensate and 5.12 billion cubic meters of natural gas in 15 years had to be absolute and future-proof.

Thorough project execution plans were drawn up to synchronize with timelines for platform construction and commissioning. Comprehensive site surveys were done to ascertain the critical systems requirements.

The solution provided wide-ranging radio functionality in VHF-AM (Airband), VHF-FM (Marine), and HF SSB Radio bands using sea-worthy equipment.

This included survival craft and lifeboat communication systems like Search and Rescue Transponders (SART), Global Marine Distress Safety System (GMDSS), and Emergency Position Indicating Radio Beacon (EPIRB)

In addition, the solution included a redundant PAGA System, hybrid EPABX System, Application Specific LAN, Non-Directional Beacon (NDB) system, and state-of-the-art Weather Monitoring Instrumentation.

The project entailed rigorous monitoring of air, sea, and environmental parameters to ensure the safe and uninterrupted functioning of the entire offshore platform.

Meteorological and Environmental Instrumentation was installed for providing real-time weather and sea-state information, which helped make informed decisions about flight movements, supply and support boat activities, and other weather-dependent tasks. Sensors were installed for measuring outside temperature, dew point, barometric pressure, wind speed and direction, sea current speed and direction, wave height and frequency, and tidal level. The instrumentation data was displayed in real-time and also recorded in archives.

A digital PAGA system was implemented, for the first time, for an end user’s offshore platform. The entire area was covered in three zones, with the sound levels carefully calibrated to be 10-20dB (A) greater than the background noise, and with the provision of additional beacons in areas of background noise above 85dB (A).

The cabling used for the PAGA system was armoured and fire-resistant. All outdoor speakers were corrosion-resistant with IP66 ingress protection, and IEC/ATEX Zone 1 certified. Crane shout control units were installed for assisting crane operators while lifting heavy loads even in emergency conditions.

The Highlights

  • Environmental Instrumentation System for temperature, pressure, rain, wind and sea current monitoring.
  • Global scope of project, meeting all delivery challenges on a timely basis.

The Benefits

Our ‘3C Model’ (Conceptualize, Construct and Care) proved effective in delivering the project to performance and timeline objectives. Going the extra mile to support all parties involved is something that comes naturally to us at Commtel. The systems were designed in-house and constructed at the yard with meticulous attention to detail, always keeping in view the real offshore conditions.

Seamless implementation of multiple systems directly at the overseas offshore construction yard maximized the efficiency of time and resource utilization. Commtel’s years of experience have proven useful so ensuring that the technical integrity of the solution was maintained at all times and only existing, well-proven designs were selected. This goes a long way in reducing downtime.

Our experienced site engineering team, through their determined efforts, completed the installation and testing within the project schedule, while adhering to proper HSE practices required on the platform. The outcome was a first-rate offshore communication system that the end-user can safely depend on at all times.
