Cathodic Protection - Consultancy Services

BEASY, a world leader in corrosion modelling provides both corrosion modelling software and modeling services. With today’s need to reduce risk and uncertainty, we can quickly provide the answers you need on the effectiveness of corrosion control solutions.

How can BEASY help you?

BEASY’s Services offer specialized analysis in the area of Corrosion Modelling. Available services range from performing specific modelling tasks to comprehensive studies to determine the optimum design solution. Our engineers have extensive expertise in applying state-of the art BEASY Corrosion Modelling to solve complex corrosion control problems. BEASY engineers can quantify the level of protection provided to the structure without any simplifying assumptions.

What type of structures and materials can be assessed?

There are no restrictions on the structure geometry that can be modelled, and these can be offshore, subsea or onshore including shallow coastal waters. Materials include steel - coated or uncoated; other metals; reinforced concrete & hybrid structures. We can help determine how the CP system will perform over time so that you can improve the timing and quality of your inspection and maintenance programs. Using BEASY’s unique technology our staff can predict the location of damage based on data from field potential surveys or ICCP reference cell data. We can also estimate the service life of sacrificial anodes and the optimum location of ICCP.

For marine applications, the modelling process can be set up to allow for the effects of long term calcareous scale development, and to identify whether the structure will initially polarize. In addition, the facility exists to incorporate the effects of water flow rate profile and its impact on the behaviour of the immersed area of metal.

Optimize Designs

Optimize CP System Designs

Optimize CP System DesignsComputer models are the ideal solution to test the sensitivity of a proposed design to environmental factors and long term coating degradation. The protection potential distribution achieved and the current demand on the anodes can be predicted, for example, under different coating conditions and the most cost effective system identified. Attenuation (eg in pipelines, ribbon anodes and cabling) losses can be addressed.Circuits representing components in an ICCP system can be constructed.

Verify Retrofits

Verify Performance of Retrofits

Retrofits are a common requirement, driven by changing requirements such as the addition of new ‘tie-ins’ and the need to extend the life of structures. Computer modelling can provide the  information you need to identify the most cost effective solution which meets the design goals.

Predict Systems

Predict Long Term Performance of CP Systems

Offshore Wind Farm Predict Long Term Performance of CP SystemsModelling can predict the long term effectiveness of the CP system, including changes in the environmental conditions, coating degradation and possible damage scenarios.

Assess Anode

Assess Anode Consumption Rates

The service life of individual sacrificial anodes and their performance over the life of the structure can be predicted by computer modelling.

Predict Potentials

Predict Protection Potentials

Cathodic Protection - Consulting Services - Verifying Performance Of RetrofitsComputer modelling provides the tools to predict how a particular system will perform even for the most complex situations and provides quantitative information on the value, and distribution, of protection potentials achieved together with the current distribution.

Output can be provided at defined intermediate dates between the installation/commissioning date and the design end-of-life date. These projections provide valuable input to targetting of subsequent survey activities (eg where measurements can be focused).

Interference

Assess interference from Adjacent Structures and CP Systems

Assess Anode Gas PipelineComputer models provide the information to determine the corrosion related electric fields and how they interfere with other nearby systems. They can provide the data to investigate the root cause of interference and the effectiveness of mitigation measures.

Understanding the complex interaction between cathodic protection systems is becoming more complex as the industry moves to deeper water and remote environments where subsea technology is a key factor. Computer modelling can play a major role in predicting the level of interaction and providing the key data for the design of the system and its integrity management. BEASY engineers have extensive experience in modelling oil and gas facilities including the interaction with subsea equipment.

A recent project has shown that interference currents can substantially reduce sacrificial anode life by factors of 3-4 and significant currents can flow in the lines connecting the components of the system unless the ICCP system is designed and operated correctly.

Support Planning Of Maintenance

Data from computer modelling can make a valuable contribution to Risk Based Inspection planning and interpretation of data by providing information to enable you to know with confidence what is occurring on your structure at any time. Thus timings of future maintenance and retrofits can be optimized.

Reduce Costs through Improved Inspection Strategies

Use computer models to determine what the data really means and optimise the planning of surveys.
