Initial one-time capital and reserve funding dominate costs (~$0.93B), driven by subsea infrastructure, vessel/ROV fleets, and large contingency reserves; annual operations are substantial (~$46.5M/yr) led by vessel/ROV ops, facility maintenance, staffing, and legal/cover costs.

⚡ Cost Scenarios
📊 Baseline (baseline) $48.2M/yr
81.5% probability / year
Normal uneventful year with continuous monitoring and routine maintenance; no major salvage or catastrophic events.
no major encounters routine maintenance and patrols
🚨 Minor Incident $50.7M/yr
15.0% probability / year +$2.5M vs baseline
Localized hostile interaction or small-scale attack requiring emergency response, extra ROV/AUV sorties, urgent satellite tasking, PR/compensation and limited recoveries.
surface/small-vessel damage short SAR/medical response urgent forensic recovery
🚨 Major Salvage Operation $86.5M/yr
3.0% probability / year +$38.3M vs baseline
Major deep-salvage or recovery after catastrophic vessel loss or large wreckage requiring specialised 6,000m salvage mobilization.
large vessel destruction need to recover sensitive wreckage
🚨 Catastrophic Mitigation $396.5M/yr
0.5% probability / year +$348.3M vs baseline
Large-scale escalation or threat to major shipping lanes requiring full mobilization and use of catastrophic mitigation funds (global coordination).
threat to major commercial routes multi-ship mobilization international exposure

📋 Confidence Notes
Analyst notes provide detailed line items and ranges allowing a reasoned midpoint estimate, but large optional reserves, choice between purchase vs charter, and uncertain incident frequency produce material uncertainty; hence medium confidence.
