Same canonical CoatingPassport data product as every other Hullproof vertical, applied to a offshore platform jacket. Domain knowledge (applicable standards, severity calibration) is automatically applied via the domain registry — adding a new asset class is a directory, not a rewrite.

Top drivers — every point traces to a finding or metric
Every point of `index` traces to a finding_id or SHM metric in `drivers`; recompute the same passport to reproduce. Indicative only — Hullproof sets no premium and takes no risk; this is the signal a market prices against.
Measured = read from a sensor / instrument / file header. Estimated = derived from a proxy. Modeled = AI / algorithm output. Declared = operator-supplied. Nothing is presented as stronger than its provenance.
Surface-breaking crack, 38 mm length, oriented transverse to weld toe. Consistent with fatigue propagation per DNV-RP-C203 S-N curves for offshore tubular joints.
General corrosion in splash zone, estimated 11–13% wall-thickness loss over a 1.4 m vertical band. Within NORSOK N-005 monitoring threshold but above 10% trigger for accelerated re-inspection.
Sacrificial anode array 76% depleted (4 of 8 anodes fully consumed, 4 partially). Cathodic protection capacity below design margin per DNV-RP-B401.
Mussel and barnacle growth averaging 80–110 mm thickness on upper jacket members. Hydrodynamic loading per NORSOK N-003 increased by ~8% vs clean-condition baseline.
Localized pitting, max depth 1.6 mm across a 0.3 m² area. Below DNV-RP-B401 immediate action threshold.
The same JSON powers Cognite CDF Asset+Timeseries, OSDU exports, RDF knowledge graphs, and MCP-tool calls from agentic systems. PDF is a renderer of this; never the source.
