Cathodic protection (CP) engineering
iicorr offers expertise in a wide range of CP engineering activities for offshore structures and vessels, FPSOs, pipelines and tanks, including:
- CP system design, supply and installation
- CP surveys (CIPS, DCVG and Pearson) and evaluation / auditing of existing systems
- Data management and monitoring
- Project management of installations, supported by many years of global experience
Cathodic protection techniques
iicorr engineers have access to a full range of cathodic protection techniques for both sacrificial and impressed current systems, such as boundary element analysis software, which is used for verification of cathodic protection on the majority of offshore projects.
Cathodic protection modelling services
iicorr offers cathodic protection modelling services based on a very powerful software package, which has a large database from widespread, real-world offshore / onshore CP system performance, and the knowledge and extensive experience of the world leader in offshore CP modelling.
Corrosion monitoring and engineering services
iicorr’s corrosion services team provides a wide range of corrosion / erosion monitoring and engineering services. iicorr covers traditional monitoring technologies and is a world leader in particle flow monitoring during well-testing operations and in the application of FSM monitoring technology in high temperature and subsea applications.
iicorr’s corrosion services include:
- Well-testing particle in flow monitoring
- Sand monitoring services and equipment
- Corrosion monitoring services (retrievals) and supply of probes and coupons
- FSM support services and the supply of systems
- Data assessment, reporting and management
- Operations support, including on-line help
- The full Corrocean product range
- Product installation, commissioning and maintenance
Corrosion monitoring equipment
iicorr’s comprehensive portfolio of state-of-the-art condition-monitoring equipment can detect and quantify corrosion, erosion, sand production, pressure, temperature and flow force in conventional and subsea oil and gas wells, as well as monitor and quantify corrosion, cracking, pitting and erosion in any industrial process piping.
iicorr’s range of equipment includes pipeline fittings, retrieval equipment, probes and coupons, corrosion meters and loggers, which help you to maintain asset integrity and reduce explosion hazards.
Access fittings, plugs and covers
iicorr offers a complete range of access fittings, plugs, standard and pressure retaining covers. Access fittings provide safe access to pressurized pipelines for equipment such as corrosion monitoring coupons or probes.
Corrosion data – retrieval and management
iicorr provides a full range of tools for reading probes and presenting the best analysis and results. iicorr’s tools also work with other manufacturer’s probes.
Sand detection and erosion monitoring
iicorr’s sand detection / erosion and corrosion monitoring probes and sensors quantify sand production and erosion, and warn against well bore collapse. iicorr’s sensors measure directly, require no calibration, and are not affected by mechanical noise. Potential operational problems can be foreseen with iicor’s monitoring equipment.
Subsea sand and erosion sensor
iicorr’s SenCorr SE system offers sand monitoring close to the reservoir, detecting sand production at an early stage, and minimizing the damage to chokes and valves. The SenCorr SE system is not affected by flow noise and no calibration is required.
Non-intrusive corrosion monitoring
Field signature method (FSM) is a unique, non-intrusive technique for monitoring changes in a pipe wall over a relatively large area of pipe. The technique can also be used for storage vessels or any other metallic structures. By inducing an electrical current into selected sections of your structure, FSM monitors changes in the electrical field pattern due to general corrosion, pitting, erosion or cracking.
Corrosion inspection tools
iicorr provides the FSM inspection tool (FSM-IT), the portable, NDT version of FSM. It reduces inspection time for Y and T-joints from hours to minutes. iicorr can evaluate asset integrity without dismantling equipment, grinding off coatings or refitting insulation.
User-friendly PC-software and fixed sensors mean operator-independent results. FSM-IT is the fastest and most accurate state-of-the-art tool for non-intrusive corrosion monitoring.
