Offshore Oil & Gas

Ensuring operations continuity in harsh environments

Computer-aided design solutions for corrosion protection systems

Fixed offshore platforms and Floating Production and Storage Units (FPSOs) are complex structures with many corrosion challenges often resulting in critical design requirements.

Elsyca's solutions support the corrosion prevention and maintenance teams to optimize Sacrificial Anode Cathodic Protection (SACP) or Impressed Current Cathodic Protection (ICCP) systems and ensure the expected life cycle of any offshore platforms or vessels. The adoption of Elsyca's solutions results in:

computation of protection level and local current density of any structure type (semi-submersible rigs, oil platforms, subsea systems, etc);
consideration of time-dependent effects like coating degradation and calcareous deposit formation;
prediction of the sacrificial anodes service life;
optimization of retrofit programs and maintenance budget.

Ensure long-term service life by developing appropriate and cost-effective corrosion protection systems through detailed modeling of your structure and corrosive environment.

A comprehensive approach

Accurately analyze

Cope with all parameters affecting the effectiveness of the protection systems thanks to our fast and accurate 3D CAE engineering solution. Our numerical solution allows to:

generate high-quality finite element meshes for cathodic protection analyses;
consider all 3D geometrical characteristics as well as water depth, soil seabed conditions, and seawater flow velocities and resistivities;
rely on embedded environment, materials, and coating polarization curves;
compute Off-, On-, IR-free potentials and current densities;
predict calcareous layer growth, and anode dissolution and shape change for anode consumption rate analysis.

Optimize

Being able to understand the impact of design, material, and environment have on corrosion protection during the early design phase of the process allows to:

secure minimum protection level with optimum anode distribution;
avoid overprotection and position reference cells at the exact and highest risk locations;
optimize remote ICCP anode sleds to compensate for end-of-life SACP systems;
optimize the total CP current demand and ensure an even CP current distribution.
