MT Demo Suezmax — Coating Passport

IACS UR Z10.4 close-up survey of a Suezmax tanker double-bottom ballast tank. Coating breakdown approaching IMO PSPC area-renewal threshold, suction-bay pitting, anode-set mid-life. Same canonical CoatingPassport as the cargo-hold and vessel-hull demos.

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.

Findings detail

coating breakdown

confidence 91%478 framesimg-quality 86%severe

IMO PSPC coating breakdown estimated 21% over forward inner-bottom area. Exceeds 10% touch-up threshold, approaching 20% area renewal trigger.

Location: Inner bottom plating, forward 1/3 of tank (12, 6, 2)

Recommended action: Schedule spot-blast + recoat at next drydock. If breakdown progresses >25% before drydock, advance scheduling.

pitting

confidence 84%198 framesimg-quality 79%moderate

Pitting cluster at suction bay, max depth 2.8 mm. Below IACS CSR 4 mm renewal threshold.

Location: Suction-bay plating (8, 0, 0)

Recommended action: UT thickness mapping at next inspection; trend pit depth progression.

anode depletion

confidence 92%87 framesimg-quality 88%moderate

Anode set 56% depleted. Within expected 5-year drydock cycle progression.

Location: Sacrificial anode set, aft bulkhead (15, 8, 0)

Recommended action: Plan anode replacement at next drydock.
