Subsea Engineering

Our subsea engineering skills ensure safe management of wells, structures, flowlines, umbilicals and risers in both shallow and deep water facilities. We have very effective design and analysis capability derived from supporting new and existing field developments.


Subsea facilities continue to become more and more challenging due to increased temperatures and pressures, complex profiles and progressively more complex completions. This requires a diverse but integrated team of experts that fundamentally understand dynamic reservoir characteristics, equipment design and analysis, operational requirements and potential degradation threats.

We are involved in many aspects of subsea engineering, including:

  • Well integrity management
  • Subsea infrastructure integrity IMR
  • Modelling of pipeline walking and critical buckling locations
  • Subsea structural design and analysis
  • Cathodic protection design and in-service assessment
  • Pipeline pigging feasibility and intelligent inspection management
  • Flexible riser annulus testing management
  • Subsea equipment decommissioning engineering
  • Pipeline change-of-use notifications
  • Regulatory and ICP interaction


From our experience with past and present clients, there are many benefits from our subsea engineering support services.

Improved functional reliability and safety of subsea infrastructure

Clear and demonstrable IMR assurance activities and reliable remnant life integrity assessments

Elimination of design limit exceedance, repeat failures and excessive degradation

Continual improvement for full field life and strong foundations for asset-life extension
