AMOG uses advanced structural analysis capabilities and leading edge materials corrosion knowledge to develop remediation and life extension schemes for degraded or aged steel reinforced concrete structures. This experience extends to the initial inspection and condition assessment of structures, determining rates of corrosion progression, analysis of residual strength, development of cathodic protection schemes, and development of fibre reinforced plastic (FRP) composite repair schemes.
We offer the following services for concrete structures’ life extension and remedial engineering:
- Development of Inspection Schemes for Condition Assessment
- Specification and Management of Diver Inspections for Waterside Structures
- Assessment of Residual Strength of Degraded Structures
- Assessment of Corrosion Damage Accumulation and Residual Life
- Development of Cathodic Protection Schemes for Steel Reinforced Concrete Structures
- Development of FRP Repair Schemes to increase Structural Capacity
- Specification f Long Term Inspection and Condition Monitoring Programs
We offer the following services for metal structures:

- Assessment of Fatigue Life from Operational, Environmental, and Thermal Loads
- Development of Cathodic Protection Schemes for Steel Reinforced Concrete Structures
- Development of Targeted Structural Refurbishment and Inspection Schemes
- Specification of Long Term Inspection and Condition Monitoring Programs
- Development of Risk-based Structural Integrity Management Systems
- Australian Agent for the CrackFirst Fatigue Sensor System
We understand the dynamics and environmental loadings in marine applications to conduct structural assessments of marine assets such as FPSOs and other general ship structures. Such assessments can be used to evaluate the structural integrity of the vessel and to support programs of life extension, optimise maintenance regimes, assess structural risk for extreme operating conditions or develop structural modifications to mitigate existing damage.
This expertise in hydrodynamics, advanced numerical analyses, and model testing, combined with our experience in offshore operations enables us to offer an efficient, accurate and reliable framework for the integrity management of whole subsea systems including mooring, riser, umbilical, hulls, and ancillary equipment.
The benefits of a whole system integrated management philosophy are:
- Reduction in the Cost of Inspection and Maintenance
- Optimisation of System Uptime and Reliability
- Provide Framework for Implementation of Remedial Actions
- Increase Confidence in System Integrity
