Initial capital and construction (nets, dredging, vessels, contingency) dominate one-time costs (~$27.2M); annual operations (staff, patrols, feeding, maintenance, research, and cover/legal) run in the low multi‑million range (~$3.43M/year). Main drivers are large-scale relocation/contingency reserves and ongoing maritime security and maintenance.

[#30] Worst-case purpose-built coastal/enclosed containment facility or permanent relocation (midpoint ~20M; highly variable).
Facilities $2.4M
[#1, #7] Anti-submarine net purchase/installation and initial dredging to shape bay (net install ~850k; dredging ~1.5M).
Contingency Reserve $2.0M
[#20] Recommended contingency reserve for major emergency salvage / heavy-lift operations (~2M reserve; scalable).
Equipment $1.7M
[#5, #11, #15, #16] Major hardware purchases: ROV(s) (~300k), patrol craft fleet (~1,000k for two boats), sonar/hydrophone deployment (~250k), visual telemetry/camera hardware (~125k).
Net Replacement Per Event $500K
[#2] Full net replacement lifecycle cost per replacement event (periodic; not annual): midpoint ~500k.
Decontamination End Of Life $300K
[#29] Planning and potential end-of-life disposal/decontamination fund (midpoint ~300k; highly variable).
Initial Research And Lab Setup $125K

Specialized Training Initial $120K
[#14] Initial maritime/security/ROV training for the initial cohort (~120k for 12 personnel at ~10k each).
Initial Permitting $100K
[#10] Upfront environmental/permitting/cover-story legal work and initial remediation expenses (~100k one-time).
Data Storage Initial $60K
[#25] Initial secure IT/classified data infrastructure (on-site server, classified comms hardware) ~60k.

⚡ Cost Scenarios
📊 Baseline (baseline) $3.4M/yr
87.5% probability / year
Normal uneventful year with scheduled maintenance, feeding, patrols, research, and ongoing cover/legal work.

🚨 Minor Incident $3.6M/yr
10.0% probability / year +$200K vs baseline
Localized net damage, small breach, or an incident requiring targeted salvage and repair but not massive operations.

🚨 Major Breach $5.4M/yr
2.0% probability / year +$2.0M vs baseline
Significant net failure or larger-than-normal shoal activity requiring extended salvage, major net replacement, and heavier dredging/repairs.

🚨 Catastrophic Breach $13.4M/yr
0.5% probability / year +$10.0M vs baseline
Catastrophic containment failure requiring activation of contingency reserve, large-scale heavy-lift operations, or start of permanent relocation/construction.

Role Count Notes
Security Officer / MTF Agent 12 [#13] Shore and vessel security for 24/7 coverage (three shifts; salaries included in staff_wages).
Research Scientist 4 [#17] Marine biologists/lead researcher and technical staff (continuous study & monitoring; salaries included in staff_wages).
Administrative Staff 2 [#26] Site director/admin assistant/contract management (salaries and overhead included in staff_wages).
📋 Confidence Notes
Many line items have well-defined commercial ranges (boats, dredging, nets, salaries) so mid-range estimates are reasonable, but large uncertainties remain around rare catastrophic events, ecological/regulatory costs, and the scale/scope of worst-case relocations, so confidence is medium.
