MV Demo Bulk — Coating Passport

IACS close-up cargo hold survey on a 2014-built Supramax bulk carrier after sequential iron-ore voyages. Same CoatingPassport schema as vessel-hull and offshore demos — proves the data product travels across maritime use cases without per-vertical engineering.

Findings detail

corrosion

confidence 87%198 framesimg-quality 81%moderate

General corrosion with iron-ore residue staining, estimated 14% wall-thickness loss over 12 m² area in lower-hopper plating. Within IACS CSR substantial corrosion threshold, requires monitoring at next intermediate survey.

Location: Lower-hopper plating, port side (12, 8, 4)
Recommended action: UT thickness gauging at next intermediate survey; plan re-coating campaign for next drydock cycle if loss exceeds 20%.

coating breakdown

confidence 91%412 framesimg-quality 86%severe

Coating breakdown estimated 22% across tank-top plating, consistent with grab-impact abrasion from previous unloading operations. Active corrosion visible at breakdown edges.

Location: Tank top plating, starboard inner-bottom (6, 4, 2)
Recommended action: Spot-blast + recoat affected zones before next loaded voyage; review cargo-handling SOPs to reduce future grab impact.

pitting

confidence 83%156 framesimg-quality 78%moderate

Localized pitting cluster with max depth 2.8 mm. Below IACS CSR 4 mm renewal threshold but above 1.5 mm monitoring trigger.

Location: Transverse bulkhead vertical strake, lower 1/3 (15, 14, 8)
Recommended action: UT measurement at next inspection; plan pit-filling if exceeds 3 mm.

deformation

confidence 76%67 framesimg-quality 73%minor

Local deformation ~8 mm displacement, likely from grab impact. Below structural concern threshold.

Location: Lower stool top plating, port side (9, 0, 12)
Recommended action: Document for trending; no action this cycle.
