Cathodic protection system retrofit & life extension

Operators and integrity teams responsible for ageing subsea and offshore assets face increasing corrosion risk as original cathodic protection systems lose effectiveness. Diminishing anode output, coating damage and limited access make it difficult to maintain full protection, while full replacement often requires long and costly vessel campaigns.

Adapt corrosion control to asset condition

Targeted retrofit solutions restore effective corrosion control by adapting protection to the asset’s actual condition, environment and material composition, including carbon steel, stainless and high-alloy steels. This provides a clear basis for integrity management, maintenance planning and continued compliance, supporting service life extension across platforms, pipelines and subsea structures.

Declining anode performance exposes steel to corrosion
As sacrificial anodes approach depletion, protection levels drop and corrosion accelerates, increasing the risk of structural degradation if action is delayed.

Restricted access makes replacement slow and costly
Complex geometries and subsea constraints drive long vessel campaigns, raising cost, schedule risk and operational disruption.

Unverified retrofit designs weaken protection reliability
Without validated design input, retrofit solutions can result in uneven current distribution, leaving parts of the asset inadequately protected.

Limited condition insight undermines maintenance planning
Insufficient data on remaining anode capacity and protection status makes it difficult to prioritise actions and plan interventions with confidence.
