FiGS® is a unique non-contact inspection tool that completely transforms Cathodic Protection surveying for submerged marine structures.

FiGS® is the most advanced cathodic protection survey technology in the market. It equips you with a precise understanding of your assets’ condition faster and with more comprehensive data, enabling well-informed decisions that can lead to significant cost savings in life extension and anode replacement projects.

FiGS® is significantly more sensitive and accurate than any other cathodic protection survey technology available

Utilising state-of-the-art non contact Field Gradient Sensor technology, FiGS® carries out highly accurate measurements with a resolution and detection level that surpasses all other cathodic protection survey methods even when the target is buried.

A FiGS® survey is the fastest way to acquire reliable cathodic protection system data

The FiGS system is the most efficient method available for measuring the status of Cathodic Protection. It cuts operational time, resulting in lower vessel and ROV costs and associated environmental impact, making it an invaluable tool for both energy companies and offshore engineering contractors.

FiGS® data allows accurate predictions about future condition of your assets

Major Energy Operators all over the world have already adopted FiGS® as their standard tool for Subsea Integrity Management due to the unmatched data quality and survey efficiency, as well as the system’s unique data reliability, which enables precise predictions of the future condition of underwater assets.

Non-Contact Cathodic Protection Survey

Periodic stab measurements are the traditional method for cathodic protection inspection. Unlike a FiGS® survey, which enables data to asses show hard the anodes are working, stabbing comprises local measurements of just the electrochemical potential and accurate readings can only be obtained through direct contact with the anode or on bare metal, if available.

The output is solely information about the current status of a cathodic protection system. A large number of readings combined with cathodic protection modelling are typically required to be able estimate the future cathodic protection status of an asset. Further, costly and time-consuming cleaning of the measurement area is usually necessary in addition ensure a dependable reading.

Using non-contact sensors, no cleaning is required prior to a FiGS® cathodic protection survey, making it much faster to identify issues related to coating degradation and damage. It’s easy to pinpoint anodes that are not working as intended, and cathodic protection current drain to adjacent structures. Critically, with FiGS®, it’s easy to identify these issues whether the pipelines or structures being surveyed are buried or not.

Knowing the exact condition of your cathodic protection system allows for an accurate assessment of remaining service life – this can only be achieved using FiGS®

Versatile Applications of FiGS® in Cathodic Protection Survey

The FiGS® system revolutionizes the way cathodic protection surveys are conducted across various subsea assets. Designed generally for oil & gas and offshore renewable industry users, FiGS® brings unparalleled precision and efficiency to assessing the integrity of pipelines, jackets, and submerged structures, whether exposed or buried.

Ideal for extending the lifespan of almost any critical underwater infrastructure, FiGS® supports detailed cathodic protection modeling, enabling predictive maintenance and strategic retrofitting to safeguard your valuable assets against corrosion.

FiGS® is transforming integrity management across wide-ranging applications, from routine inspections to comprehensive lifetime extension and full-field projects.

Subsea structures and pipelines

Subsea pipeline integrity

FiGS® delivers detailed cathodic protection evaluations on exposed and buried pipelines, accurately assessing potential profiles, anode condition, and coating integrity in less time and at lower cost than traditional inspection methods.

Jacket inspection

FiGS® enhances the service life of offshore structures by providing precise, non-contact cathodic protection assessments through advanced field gradient measurements, thus reducing the operating time required for offshore vessels and ROVs.

In-field structures

Through the ability to identify coating defects and evaluate anode performance, FiGS® is a critical tool to ensure structural integrity and extend the operational lifetime of any underwater structure that requires the use of a cathodic protection system, quickly and cost-effectively.

Subsea integrity management

FiGS® contributes to effective subsea asset management by providing detailed insights into the corrosion protection status, supporting data-driven maintenance and risk management strategies across an entire development.

New generation AUV operations

FiGS® integrates seamlessly with new generation AUVs and resident drones for on-demand, advanced, high-speed cathodic protection surveys that maximize operational efficiency and data accuracy while significantly reducing costs related to cathodic protection maintenance.

Gravity based structures

Enhancing both the longevity and safety of foundational gravity-based structures, FiGS® provides effective cathodic protection assessments by detecting electric field gradients and current densities, enabling precise evaluations of anodic efficiency and coating integrity.

FPSO / hull / mooring lines

Because FiGS® enables precise detection of coating defects and anode performance quickly, it ensures optimal cathodic protection maintenance, helping to extend the service life of both FPSO hulls and their associated mooring lines.

Offshore wind

FiGS® reduces lifetime cost of operations & maintenance for offshore wind structures with precisely evaluated cathodic protection data (including coating damages and anodic efficiency) integrated within an integrity management system for a single, or multiple wind farms.

Cathodic protection modelling

Because FiGS® has the unique capability to define the direction of electric currents, it enables areas of interest, such as coating damages, faulty anodes, stray currents and more to be pinpointed and visualized. Through this, tangible savings are available by using real-life current densities as opposed to conservative design codes.

With cathodic protection modelling, it’s easy to try out different scenarios in order to ensure the optimal protection of your asset. Typical cases evaluated by cathodic protection modelling include:

  • Current shadow effects, current drain and anode distribution issues
  • Uneven anode consumption
  • Over or under protection
  • Protection in confined areas, small annuluses, gaps etc.
  • Galvanic corrosion
  • Anode interference
  • Interaction between connected structures
  • Pipeline attenuation
