Same canonical CoatingPassport applied to Hullproof's first vertical — maritime hull inspection. Routine in-water survey on a 2018-built container vessel approaching pre-drydock window. Biofouling, anode depletion, coating breakdown, propeller marine growth — all in structured JSON, with PDF, Cognite CDF, OSDU, and RDF exports derived from the same source.
IMO biofouling rating BR3-4 over ~38% of midship vertical sides. Heavy slime + barnacles + tubeworms. Consistent with extended idle period or out-of-spec anti-fouling performance.
Coating breakdown estimated 11% over a 8 m × 2 m band near port-bow waterline. Likely impact/abrasion from prior berthing operations rather than systemic AFC failure.
Sacrificial anode set 52% depleted across stern frame. Within expected progression for 24 months since last drydock.
Heavy biofouling on propeller blades, with visible barnacle attachments on leading edges. Estimated 6-9% fuel-consumption penalty per typical IMO calibration curves.
Isolated paint blistering across ~0.4 m² area. Below intervention threshold.
Supporting evidence for a primary-data fuel/intensity figure — not the ISO 14083 calculation and not a replacement for EU MRV / FuelEU monitoring. A fouled hull burns more fuel per tonne-km; this is the verified condition that defends a lower self-reported intensity.
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.
