Diver-Assisted Subsea Composite Repairs

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:

  • External corrosion and coating breakdown
  • Mechanical damage from seabed interaction or dropped objects
  • Long-term exposure to marine environments
  • Limited access for inspection and intervention

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:

  • Composite systems formulated for underwater application and cure
  • Diver-applied installation without asset recovery
  • Compatibility with controlled subsea surface preparation
  • Application across oil & gas, renewables, and marine infrastructure

The result is a practical, reliable subsea repair solution that restores asset integrity while minimising offshore intervention and downtime.

Splash Zone & Near-Surface Structural Repairs

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:

  • Accelerated corrosion in alternating wet/dry conditions
  • Mechanical loading from waves and currents
  • Coating damage and exposure of bare substrate
  • Structural loss at interfaces and transitions

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:

  • Structural loss compensation in splash-zone regions
  • Long-term corrosion and erosion protection
  • Compatibility with complex geometries and transitions
  • Durable performance in highly aggressive environments

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.

Impact Damage Repair & Asset Stabilisation

Subsea pipelines and associated structures are vulnerable to impact from dropped objects, vessel interaction, anchors, and seabed movement. Damage mechanisms commonly include:

  • Localised denting or deformation
  • Coating breach and exposed substrate
  • Structural instability or loss of support
  • Increased risk of progressive failure

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:

  • Structural stabilisation following impact damage
  • Repairs to mixed-metal systems, including CuNiFe
  • Caisson and support structure reinforcement
  • Prevention of asset movement or seabed loss

The result is a stabilising subsea repair solution that protects asset integrity and reduces the risk of escalation or catastrophic failure.
