Home » Structural Integrity Management (SIM)

ABL offers Structural Integrity Management (SIM) for Oil & Gas facilities, Renewable Energy assets and Ships. Our services include all aspects of SIM delivered by our staff with extensive experience in operation, repairs, modifications and design of FPSO, FSO, fixed and floating platforms, and ships of various types.

Combining practical field experience with multi-disciplined engineering expertise, our specialists help clients understand asset condition, manage risk and optimise inspection, maintenance and repair strategies across the asset lifecycle.

Significant safety and cost benefits can be achieved by ABL’s SIM services for hull and substructure, topsides and mooring systems of assets at all stages of their lifecycle – from design and construction, through operation, and to decommissioning.

Our Services

Structural Integrity Management Services

End-to-end support to safeguard asset integrity and operational performance.

SIM Strategy and Optimisation

ABL develops new SIM processes or reviews and optimises companies’ existing SIM processes for fixed and floating structures.

The SIM process will be tailored to specific assets and company procedures and comply with recognised industry standards (ISO 19901-9 and API RP 2SIM) and asset-specific risk profiles.

Inspection Programs & Work Packs

ABL develops, implements and updates periodic, continuous, and Risk-Based Inspection (RBI) programmes, that focus resources where they add greatest value, with clear work packs that reduce inspection time, resource demand and unforeseen scope variation.

The RBI programs are compliant with expectations of the government safety and marine authorities and receive approval of Classification Societies for classed systems (e.g. hulls and moorings of FPSO).

Survey and Inspection Management

ABL’s experienced surveyors manage and oversee detailed inspection scopes which consist of visual inspections and specialist inspection techniques including Non-Destructive Testing (NDT).

ABL facilitates the use of unmanned inspection technologies (drones and ROV) and 3D photogrammetry for reducing risks to inspection personnel and improving inspection efficiency.

Anomaly and Risk Management

ABL provides comprehensive anomaly and risk management services, including structured registers, engineering assessments, mitigation plans and Management of Change support.

We can develop or maintain anomaly databases to track risks, mitigations and repairs, while assessing anomalies and operational changes against company risk matrices to determine criticality and implement effective, cost-efficient mitigation measures.

Fitness for Service Assessment

ABL has extensive experience in Fitness for Service (FFS) assessments for structural anomalies or changes in operating conditions using the most appropriate methods ranging from qualitative desktop assessments and, when necessary, extending to structural, hydrodynamic, mooring and stability analyses.

Repair, Modification and Life Extension

ABL delivers cost-effective repair, modification and life extension solutions that eliminate structural risks and maintain compliance with industry standards.

Leveraging practical repair strategies, including composite repair technologies and FMECA-led prioritisation, ABL helps reduce costs, minimise hot work and optimise repair schedules while supporting safe, efficient and reliable asset operation.

Site Support and Secondments

ABL provides experienced surveyors and engineers for various activities offshore, in office and construction yards worldwide, embedded within client teams to manage SIM process, strengthen delivery capability, optimise offshore and in dry-dock repair scopes from inspection and anomaly data, and review the constructability of structural repairs before execution.

Full Lifecycle Maintenance

ABL provides full lifecycle maintenance solutions, using current inspection data and insights from previous projects to predict future structural degradation and support proactive maintenance strategies that reduce repair costs and minimise production downtime.

We deliver cost-effective solutions for ageing assets, enabling continued operation without significant capital expenditure while providing tailored anomaly management for late-life assets.
