 The framework applies a Probability × Consequence model with Safety Case Barrier Mapping to quantify risk and avoid post-closure exposure. It estimates barrier failure likelihood and consequence severity, mapping risks against physical, active, and procedural barriers to identify gaps. Residual post-closure risks are assessed and mitigated or accepted within defined tolerances, ensuring all reasonably practicable measures are taken and unresolved gaps are addressed pre-MODU. 

 The model projects total financial exposure from non-compliance gaps across the MODU campaign using key parameters: MODU day-rate and hourly spread rate, pre-mobilisation resolution time and cost, and financial impacts of regulatory stop-work events, fines, and enforcement actions. Incident scenarios incorporate investigation duration and cost (excluding spread), environmental and injury multipliers, and design non-conformance remediation. All variables are assessed against planned campaign duration to project total financial liability. 

 The framework comprises eight categories to prevent, detect, and mitigate non-compliance risks across MODU operations. Well Control ensures primary containment of formation pressures; Lifting Operations governs heavy equipment handling; Ignition Control manages fire and explosion sources; and Pressure Containment maintains pressurised system integrity. Structural Integrity covers rig robustness, supported by Process Safety Systems for automated detection and response. Certification & Traceability verifies equipment and personnel standards, while Administrative and Documentation controls underpin governance through procedures, training, and audits. 

 The scenarios outline escalating outcomes if a compliance gap reaches the MODU operational phase. S0: Closed Pre-Mob is the desired state where gaps are resolved before mobilisation. S1: Discovery at Rig-Up involves gaps identified on-location, causing delays and rework. S2: Regulatory Discovery triggers formal enforcement, stop-work orders, and reputational damage. S3: Equipment Failure results in loss of containment, downtime, and emergency response. S4: Major Incident escalates to loss of life, environmental damage, prosecution, and potential asset loss. The framework prioritises resolving all gaps pre-mobilisation to prevent escalation beyond S0. 

 The assessment synthesises findings from observations, each quantified with a Potential Expected Loss value representing risk avoided through proactive remediation. Applying the Probability × Consequence framework, it determines the financial and operational exposure that would have materialised had each gap remained unresolved. The aggregated loss across all observations demonstrates total risk avoided pre-mobilisation, enabling prioritisation of high-value items, supporting resource allocation, and providing tangible evidence of the programme's effectiveness in preventing escalation. 

 A Vendor Risk Summary synthesises assessment findings into a concise, actionable format for senior management and the board, providing an at-a-glance overview of key third-party vendor risk postures. It includes risk tiering (Critical, High, Medium, Low), common findings such as access controls and configuration management, and governance gaps arising from limited in-house expertise. With vendor failures increasingly scrutinised as board-level risks, the summary demonstrates diligent oversight and proactive management of the extended enterprise, presenting vendor risk as a strategic business exposure requiring continuous monitoring throughout the vendor lifecycle.
