Offshore & Floating Production Assets
Structural integrity management for fixed and floating offshore assets — across the full lifecycle.
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.
