MV Demo Pioneer — Coating Passport

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.

Findings detail

biofouling

confidence 93%842 framesimg-quality 87%severe

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.

Location: Vertical sides, midship, 60-100 m from bow (80, 0, -3)
Recommended action: Hull cleaning before next loaded leg; investigate ROV-confirmed anti-fouling depletion zones; review next drydock specifications.

coating breakdown

confidence 86%312 framesimg-quality 82%moderate

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.

Location: Bow, port side, waterline region (15, 0, -5)
Recommended action: Touch-up paint at next available opportunity; document for next drydock specifications.

anode depletion

confidence 95%156 framesimg-quality 91%moderate

Sacrificial anode set 52% depleted across stern frame. Within expected progression for 24 months since last drydock.

Location: Stern frame anodes, port + starboard (270, 0, -6)
Recommended action: Schedule anode replacement at next drydock (within 8 months per CP design assumptions).

marine growth

confidence 89%234 framesimg-quality 84%severe

Heavy biofouling on propeller blades, with visible barnacle attachments on leading edges. Estimated 6-9% fuel-consumption penalty per typical IMO calibration curves.

Location: Propeller blades + boss (280, 0, -8)
Recommended action: Propeller polishing prior to next voyage; cost-recovery vs fuel savings typically <60 days.

paint blistering

confidence 74%47 framesimg-quality 71%minor

Isolated paint blistering across ~0.4 m² area. Below intervention threshold.

Location: Starboard side, midship, below waterline (145, -8, -4)
Recommended action: Monitor at next in-water inspection; no action required this cycle.

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.
