Subsea pipelines operate in one of the most demanding environments encountered by industrial assets. Continuous exposure to seawater, hydrostatic pressure, and limited accessibility places unique constraints on repair methodologies, with degradation commonly driven by:
Traditional repair methods often require recovery, shutdown, or extensive marine operations, resulting in high cost and operational risk.
At Icarus Composites, diver-assisted composite repair systems are specifically engineered for subsea installation, using materials that can be applied and cured underwater while delivering predictable mechanical performance.
Key performance benefits include:
The result is a practical, reliable subsea repair solution that restores asset integrity while minimising offshore intervention and downtime.

The splash zone and near-surface regions of subsea pipelines experience some of the highest corrosion rates due to cyclic wetting, oxygen availability, and mechanical wave action. Degradation in these zones is typically driven by:
These conditions often lead to rapid deterioration if not addressed early.
At Icarus Composites, composite repair systems are applied to restore structural integrity and protect pipelines and components operating in splash zone and near-surface environments.
Key performance benefits include:
The result is a robust splash-zone repair solution that withstands cyclic exposure and extends service life in one of the most challenging subsea environments.


Subsea pipelines and associated structures are vulnerable to impact from dropped objects, vessel interaction, anchors, and seabed movement. Damage mechanisms commonly include:
In severe cases, damage can compromise pipeline stability or lead to sections becoming unsupported.
At Icarus Composites, composite reinforcement systems are used to stabilise damaged assets, restore structural performance, and prevent further degradation or loss of support.
Key performance benefits include:
The result is a stabilising subsea repair solution that protects asset integrity and reduces the risk of escalation or catastrophic failure.
