Offshore & Floating Production Assets

Structural integrity management for fixed and floating offshore assets — across the full lifecycle.

Back to Industries

Offshore oil and gas platforms and FPSOs operate in some of the most demanding environments in the world. Continuous exposure to wave loading, corrosion, fatigue, and operational modifications means that maintaining structural integrity is critical to ensuring safety, regulatory compliance, and long-term asset performance.

Our team provides comprehensive structural integrity management services for both fixed and floating offshore platforms, supporting operators throughout the full asset lifecycle — from concept and FEED studies through detailed design, inspection, remediation, life-extension, and eventual decommissioning planning.

We combine advanced engineering analysis with practical field experience to assess the condition and capacity of offshore structures. Using industry-leading FEA tools, alongside digital inspection data and integrity management systems, we evaluate structural performance under current and future loading scenarios.

Our Expertise Includes

  • Structural reassessment of ageing fixed jackets, topsides and floating structures
  • Fatigue life evaluation
  • Corrosion and degradation modelling
  • Brownfield modification and load-addition studies
  • Integration of inspection findings into asset integrity systems
  • Life-extension strategies for mature offshore assets

By aligning engineering analysis with inspection data and maintenance planning systems, we help operators make informed, risk-based decisions that protect personnel, safeguard production, and extend the safe operating life of critical offshore infrastructure.

FPSO Structural Integrity & Life Extension

HPG Engineering supports structural integrity and life-extension programmes for floating production assets by integrating design information, structural analysis, inspection findings and operating history to support continued safe operation.

  • Life-extension engineering and remaining-life assessment
  • Hull structural assessment and critical-area evaluation
  • Fatigue and local structural analysis
  • Hull and topside structural interface assessment
  • Mooring and riser foundation structural assessment
  • Brownfield structural modifications and strengthening
  • Inspection and condition-data integration
  • Repair engineering and remediation strategies
  • In-service structural inspection programme development
  • Engineering support for Class and regulatory review
