Select the GCP PPS expertise you need for your project!
A typical project sequence – cathodic corrosion protection
In order to incorporate all the necessary project-specific data into the detailed planning, we offer you a site survey incl. environmental assessment, localization of location-relevant influencing factors and the necessary measurements.
Using the information you provide and the data from the preliminary measurement, we create a PPS concept tailored to your needs. Consideration of the relevant legal and customer-specific standards is mandatory. All KKS services are also designed for environmental compatibility, sustainability and durability.
For your corrosion protection project, you receive the development of special solutions and research into long-term requirements as well as technology development.
So that even extraordinary requirements can be met sustainably, you also receive the necessary supplies from a single source.
In addition to planning and calculating your KKS system, we also offer installation and assembly on site. We supply you with all the necessary elements in accordance with the planning. The extensively qualified and certified GCP employees ensure professional implementation and installation of all components from a single source. Here too, we pay particular attention to compliance with all environmental protection and safety regulations.
Before and during the installation of a KKS system, it is often necessary to carry out a wide range of activities, some of which require expert opinions. We carry out all kinds of tests and inspections in accordance with the applicable regulations, standards and any customer specifications.
We also make it possible for you at any time:
Depending on the customer’s requirements, we can prepare all the documents needed to implement a KKS system for you in the desired languages. This includes national and international regulations and environmental provisions.
As GCP’s KKS systems are designed to suit every requirement, failures are rare. Nevertheless, due to external influences, failures may occur. Of course, we are also available to assist you in these cases with our professional spare parts and maintenance service.
To ensure the effectiveness of the cathodic corrosion protection, regular functional checks of the protection systems and targeted monitoring measurements on the systems are required.
By carrying out these measurements and maintenance work as part of our KKS services, potential risks can be reliably identified and eliminated before failures and damage occur.
It is not for nothing that the legislator prescribes regular inspections for many systems. The need for action defined by you is implemented by us in such a way that you no longer have to worry about it.

Your advantages:
Remote monitoring of your corrosion protection system
You have invested in systems that display, record and report all relevant data. But who evaluates this data professionally and initiates rapid troubleshooting in the event of fault messages? We are happy to take on these tasks for you! With GCP RMCS (Remote Monitoring and Control System), a remote control system is available that provides the necessary basis. Together with you, we check your KKS systems and create the conditions for optimum telecontrol technology.
Our remote monitoring service offers these advantages:
Modular system
We tailor our services to your requirements and work with you to find the best possible solution.
Intensive measurements-CIPS / DCVG
If a regular prescribed inspection is due or specific solutions become necessary due to a malfunction, our KKS service usually begins by providing you with information about the condition of your system. So that we can jointly determine what information is required for the development of a long-term and sustainable solution, we recommend a non-binding preliminary meeting to determine your specific needs.
Once we have jointly determined your requirements, we select the appropriate processes and plan their implementation.
Proof of the effectiveness of complete cathodic corrosion protection on underground pipelines is provided by intensive measurements, among other things.
Prior to the intensive measurement, the purpose and objective of the measurement is discussed with the customer. The type of intensive measurement is also determined at this time.
Intensive measurements are carried out by our corrosion protection technicians using state-of-the-art measuring vehicles and computer-aided systems. We measure, interpret and document all intensive measurement assignments. We compile the necessary documentation for acceptance by TÜV experts.
With our documentation, you can verify the effectiveness of your cathodically protected pipelines and any defects in the pipe coating at any time. As a rule, influences from third-party installations are also shown.
With the mobile computer system, CIPS makes it possible to carry out intensive measurements in cathodic corrosion protection with the measurement of pipe/soil potentials and voltage funnels. With CIPS, intensive measurements and troubleshooting on pipelines can be carried out quickly and easily. The high-resolution and simultaneous 3‑channel measurement value acquisition, together with the simple operation of CIPS, are ideal prerequisites for precise and meaningful intensive measurements in cathodic corrosion protection.
CIPS supports various measurement methods for intensive measurement and troubleshooting
Addition method
Basic measurement at the measuring pile as with the 2‑electrode method, then additive calculation of potential and voltage funnel by measuring the voltage drop along the pipeline without connection to the measuring contact Intensive fault location (IFO) Measurement of the switch-on and switch-off potentials along the pipeline for pure fault location.
Your advantages with CIPS
Intensive fault location onshore and offshore
Using the right measuring method to prove the effectiveness of the cathodic corrosion protection of pipelines requires many years of experience. The use of these methods depends on the wrapping materials used and possible influences.
A measurement method such as intensive measurement also provides information about the potential at the phase boundary and is an excellent method for finding defects of any size, but it is difficult to carry out in urban areas. Intensive flaw location (IFO) can be used to detect even the smallest flaws in new PE-coated pipelines, but it does not provide any information about the polarization on the steel surface within the flaw. This measurement method is much faster than intensive measurement and can also be carried out well in urban areas.
In the offshore sector, remeasuring the cathodic protection of longer sea-laid pipelines is very time-consuming. In coöperation with specialist companies for hydrographic surveys, we contribute our experience in the field of cathodic protection for pipelines laid at sea. Using Data Sonic towing systems, RCVs (Remote Controlled Vehicles), Side Scan Sonar, etc., we carry out follow-up measurements using a wide variety of methods.
Specific electrical soil resistivity measurements for measuring depths >30 m
Reliable specific soil resistivity values are essential for the planning and calculation of deep anode systems for cathodic corrosion protection.
The multi-electrode geoelectric system is used to determine specific electrical soil resistances at greater depths, even with several layers. The computer-controlled electrode system is used for automatic measurements and displays the specific soil resistivity profiles in 2 or 3 dimensions.
Every KKS system can become faulty even after years of trouble-free operation. Typical examples are contact with foreign cathodes, e.g. new foundations, defective insulating sections or spark gaps due to contact with third-party installations.
We are able to carry out all different versions of troubleshooting. In particular, 100Hz technology can achieve fast and cost-effective results thanks to its precision. This applies in particular to meshed piping systems.
Defects such as pores, cracks and holes impair the coating quality and thus the corrosion resistance of a product.
The gentle testing of a wide variety of coating and corrosion protection materials with high voltage has proven itself over a long period of time. The test is prescribed by many factory standards and norms and, as part of quality assurance, makes a reliable contribution to optimizing service life, avoiding operational interruptions and consequential repair costs.
Whether externally or internally coated pipes, container rubber linings, fully encased fittings or machine parts … Wherever non-conductive layers are applied to conductive materials (e.g. metal, damp concrete) or can be underlaid with conductive materials, reliable detection of defects is possible.
Our staff are trained and certified for this work.
To ensure the quality of the pipe coating you have purchased, the NORM specifies a test procedure to determine the absence of pores (coating resistance greater than 1x10⁸ / Ohm x m²). We provide you with our qualified personnel and appropriate equipment for this purpose.
In the interests of the end customer, this measurement provides an independent result for quality assurance.
Stray currents from direct current lines, high-voltage direct current transmission systems etc. as well as alternating current can cause considerable corrosion damage to underground pipelines.
In order to determine the extent of possible influences, our corrosion protection technicians carry out long-term registrations on the affected systems.
Here, for example, potentials, DC/AC currents and all necessary data for a qualitative statement are collected.
Our corrosion protection technicians provide advice on evaluating the measurement results and determining appropriate protective measures in coöperation with the operators.
High-voltage influence calculation
The merging of power lines and the significantly improved sheathing of pipelines mean that high-voltage interference is occurring more and more frequently. A distinction is usually made between permanent and short-term influences.
In order to ensure the operational safety of the pipelines and the personal protection of their employees, extensive measurements must be taken on existing systems and new construction measures must be assessed in advance.
If required, we carry out appropriate measurements, calculations, design of protective measures, delivery of components and their installation and commissioning for your systems in accordance with the applicable technical regulations.
