Which PipePatrol modules are available for pipeline management?
PipePatrol Leak detection: PipePatrol includes a state-of-the-art system for leak detection and localisation on pipelines. The system is based on advanced algorithms and measurement data from the instrumentation to detect leaks in pipelines at an early stage. As the most sensitive internal leak detection system (LDS - Pipeline Leak Detection System) on the market, PipePatrol provides precise information on pipeline integrity, leak rate and position for maximum safety.
PipePatrol Line break detection: PipePatrol offers an efficient solution for detecting line breaks in pipelines. Pipeline ruptures can have serious consequences that endanger both the population and the environment. The system triggers an alarm and initiates the emergency shutdown procedure for pipeline operations.
PipePatrol Tightness monitoring: Small or gradual leaks in particular are often not detected by conventional systems, as environmental influences along the pipeline can mask the minor effects of small quantities of leakage on the process data being measured. However, PipePatrol offers a way to identify even slow leaks using standard pressure and temperature measuring devices in accordance with legal requirements.
PipePatrol Theft detection: PipePatrol is able to detect unusual activities in connection with pipelines, which is particularly relevant in regions with a high risk of theft. The measurement solution is based on advanced pattern recognition to quickly and precisely identify and locate unauthorised or illegal product withdrawals. Even small quantities trigger an alarm within minutes.
PipePatrol Batch tracking: This PipePatrol module monitors and tracks product batches in pipelines in real time. The precise determination of the position of batches and mixing zones ensures safe operation and optimum utilisation of pipeline capacity. This minimises the slop volume, maximises the overall yield of the pipeline and optimises productivity.
PipePatrol Stress monitoring: Pipelines are continuously exposed to mechanical stress due to changes in pressure and temperature. This PipePatrol module provides a solution for monitoring pipeline stress and its impact on service life. The results obtained can be utilised as part of a preventive maintenance approach to plan the next integrity test before a critical condition occurs.
PipePatrol Predictive modeling: This simulation tool runs in parallel to pipeline operation and represents the thermodynamic and fluid mechanical conditions. Based on real-time measurement data and operator input, future pipeline conditions can be reliably predicted. This allows possible negative consequences to be effectively countered by preventive measures.
PipePatrol Cyber security: PipePatrol offers solutions for the protection against cyber risks. Our goal is to enable secure communication in the automation and monitoring of production and process flows. In cooperation with our partners, we ensure a high level of security, which is essential for modern pipeline systems.

What are typical areas of application for pipeline monitoring and leak detection?
KROHNE PipePatrol Management is a versatile solution that can be used in a wide range of industries and applications - on both above-ground and underground pipelines. Typical areas of application for the system include the oil and gas industry, the chemical industry, the water and wastewater industry and the district heating supply sector.
In the oil and gas industry , the PipePatrol Management System plays a crucial role in monitoring pipelines that transport crude oil, natural gas and refined products. The pipelines typically extend over long distances and traverse different geographical and climatic conditions. The system helps to detect leaks and other anomalies at an early stage to minimise environmental damage and economic losses, even for products with high viscosity and unusual environmental conditions, such as deep-sea pipelines with high external pressure.
In the chemical industry , pipelines are often used to safely transport hazardous and valuable chemicals between production sites, storage facilities and processing plants. These include flammable media or gas in a supercritical state. By precisely detecting and localising leaks, even of problematic products, operators can react quickly and avert potential dangers to people and the environment.
The water and wastewater industry also benefits significantly from the implementation of an LDS leak detection system. In this industry, the integrity of pipelines is crucial to ensure the security of supply and quality of drinking water. The system continuously monitors the pipelines that transport water to households and industrial plants and detects leaks that could lead to water loss and contamination risks.
Another important area of application is the district heating supply . District heating networks transport hot water or steam from central heating plants to residential and commercial areas. KROHNE pipeline management helps to maximise the efficiency of these networks by detecting leaks and heat losses at an early stage.
Hydrogen is playing an increasingly important role, especially in the context of the energy transition and the development of sustainable energy sources. Hydrogen is considered a key technology for the energy transition, as it is a clean energy carrier that contributes to the reduction of CO2 emissions. KROHNE PipePatrol Pipeline Management is flexible and adaptable to meet the changing requirements of the hydrogen economy. This futureproofing makes it an ideal solution for the long-term planning and realisation of hydrogen networks and hydrogen projects.
How does the KROHNE pipeline monitoring system react to emergencies such as explosions on the pipeline?
As soon as an explosion or similar emergency event occurs, the pipeline monitoring system recognises the anomaly through the transmitted data from the highly sensitive sensors and measuring devices that continuously monitor pressure, flow and other relevant parameters. Immediately after detection, the system generates automatic alarms that are sent to the central monitoring stations and the relevant emergency teams. To prevent the spread of damage and increase safety, the KROHNE PipePatrol Management System has mechanisms for automatically shutting down and isolating the affected pipeline section. In the shutdown process, valves and other control devices are activated to stop the flow of the medium in the pipeline and reduce the risk of further explosions. After the emergency has been dealt with, PipePatrol supports the tracking and analysis of the incident.
How sustainable is the KROHNE pipeline protection and security system?
The KROHNE PipePatrol Pipeline management solution is designed not only to ensure the safety and efficiency of pipelines, but also to make a significant contribution to sustainability. By quickly identifying and repairing leaks, the release of harmful substances into the environment is prevented, which significantly contributes to avoiding soil and water pollution, preventing environmental disasters and protecting natural resources. The reduction of leakages also minimises the loss of valuable raw materials, which is both ecologically and economically beneficial. Furthermore, the system helps operators to optimise the energy consumption of their pipeline infrastructure. By continuously monitoring and analysing operating data, inefficient processes can be identified and improved, resulting in a reduction in energy consumption and therefore a reduction in CO2 emissions. Another important contribution that the system makes to sustainability is the extension of the service life of pipelines. The PipePatrol system continuously monitors the condition of the pipeline and recognises signs of wear, corrosion and other potential problems at an early stage. As a result, the service life of the infrastructure is extended and the need for new materials and resources is reduced.
What are the unique benefits of KROHNE's pipeline safety solution and leak detection compared to other systems?
PipePatrol's unique benefit is its comprehensive and integrated approach to pipeline monitoring, combining state-of-the-art software and technology, advanced data analytics and user-friendly interfaces. KROHNE PipePatrol Pipeline Management not only monitors leaks, but also other critical operating parameters such as pressure, flow, temperature and structural integrity, enabling holistic pipeline monitoring. Another outstanding feature of PipePatrol is the exceptional precision and speed of leak detection. For example, in one specific case, a detection time of 30 seconds with a location accuracy of 0.6% was achieved on a 31 km long pipeline.
By using advanced algorithms and sensor technologies, the system can not only detect leaks particularly quickly but also determine their position with a high degree of accuracy. The system also utilises the latest developments in artificial intelligence (AI) and machine learning to improve its detection capabilities. These technologies enable the system to learn from historical data and operating conditions.
Other special features of the KROHNE PipePatrol monitoring system are the intuitive user interfaces, which enable easy-to-understand visualisation of the pipeline data, as well as the fact that the system can be expanded modularly step by step. This makes it possible to react to changing operating conditions and to retrofit additional modules if required. Finally, it should be mentioned that KROHNE provides comprehensive service and support - from installation and commissioning to regular maintenance, training and technical support. Another advantage of the PipePatrol system is that it can be retrofitted to existing pipelines using existing instrumentation. KROHNE also offers complete project packages that include flow meters and other measuring devices as well as equipment for remote data transmission.
Are there legal requirements for pipeline leak detection?
The choice of a suitable leak monitoring system is complex: it must be suitable for the specific application and fulfil the local legal requirements. The KROHNE system fulfils the relevant national regulations (e.g. the German TRFL - Technische Regel für Fernleitungen) and complies with international industry standards - for example API 1175 (American Petroleum Institute) for the management of leak detection programmes in pipelines, API 1130 for computer-aided pipeline monitoring, AB 864 and CSA Z662.
What technologies are used for pipeline leak detection and prevention and pipeline simulation?
Various approaches and technologies are generally used to detect leaks in pipelines on an industrial scale, each of which offers specific advantages. One of the best-known technologies is pressure wave analysis: if leaks occur suddenly, they trigger pressure waves that propagate both downstream and upstream. Such pressure wave propagations can be detected by continuous pressure analysis. Another variant is based on the installation of special sensor technology along the pipeline: acoustic detectors or fibre optic sensors (e.g. fibre optic cables) are able to detect temperature changes (e.g. cooling due to decompressing gas) and acoustic noise caused by the outflow process. Also worth mentioning are Ultrasonic technologies, infrared and laser technology or visual inspection and drones.
KROHNE PipePatrol relies on E-RTTM technology for internal leak detection. RTTM ("Real-Time Transient Model") is a mathematical model that compares the real-time measurement data of the actual operation of a pipeline with the corresponding data of a "virtual pipeline" or a computer simulation. KROHNE has further developed RTTM technology and introduced E-RTTM technology for the continuous internal monitoring of pipelines. E-RTTM stands for "Extended RTTM" and combines the RTTM principle with leak signature analysis through leak pattern recognition. The E-RTTM leak monitoring system creates a virtual image of the pipeline by utilising data from the real pipeline. Key measured values come from sensors for flow, temperature and pressure installed at various points in the pipeline, such as in measuring and control stations. The recorded pressure and temperature values are used to calculate the flow rate, pressure, temperature and density for each section of the virtual pipeline. The system compares the calculated values with the actual measurements. In the event of deviations, the leak signature model analyses whether these were caused by a device error or a leak, whether acute or gradual.
How does the KROHNE PipePatrol pipeline management and monitoring system communicate?
The PipePatrol Management System uses various wireless communication technologies to transmit data from the sensors along the pipeline to the central monitoring unit. The transmission paths, e.g. secure Internet connections via VPN tunnels and SHDSL, mobile radio, Radiolink and WLAN connections, are adapted to the actual conditions on site. This ensures flexible and cost-efficient data transmission, even in remote or difficult-to-access areas. Another aspect is that PipePatrol can be seamlessly integrated into existing SCADA (Supervisory Control and Data Acquisition) systems and software. SCADA systems are widely used in the process and manufacturing industries and enable the centralised monitoring and control of plants. To ensure high availability and reliability of communication, the KROHNE Pipe Patrol Management System relies on redundant communication paths and fail-safe mechanisms. This means that if a communication channel fails, the system automatically switches to an alternative channel.
What additional challenges does pipeline leak monitoring have to overcome in hazardous areas?
The KROHNE PipePatrol Management System is designed to function reliably even in the most demanding environments. A particular challenge is posed by hazardous areas, i.e. potentially explosive zones, which are found in many industries such as the oil and gas industry, the chemical industry and the petrochemical industry. Strict safety regulations and special technical requirements apply in these areas, which the system must fulfil.
One of the biggest challenges here is the safety of the devices used. All components installed in these zones must be explosion-proof and comply with the relevant ATEX or IECEx directives. In this environment in particular, the reliability of measurement data transmission is often a challenge. Due to the strict safety requirements, conventional communication methods may be limited. The KROHNE PipePatrol pipeline monitoring system therefore offers special communication solutions that guarantee safe and reliable communication.
