Subsea power cables supply chain chokepoints

category tradeable chokepoint

How scores are shown

Criticality Criticality comes from the trace model and describes the node's dependency importance.

Evidence Evidence comes from the canonical Vein Graph: AI assertions, user corrections, and external sources.

Completeness Completeness is a data-coverage label based on available summary, evidence, sources, tickers, and chokepoint rationale.

Dynamic claims are capped below 100% and AI-only edges remain labeled as inferred. Model: trace-score-v1

Subsea export cables90% confidence — Only a handful of factories can make and load the longest export cables, so project queues are long.

European HVDC cable landing90% confidence — Landfall permits and converter integration slow projects even when turbines are ready offshore.
