This ship has no verified emissions report. We estimate a band E from its segment, size and age (100% confidence).

Estimate, not a reported figure. Within one band 95% of the time on reported peers.

Multiple adverse factors, or a hard ship-specific signal, lift this hull above the fleet norm.

A coverage-weighted blend of the 3 components we could read for this hull — the weights renormalise over only the components present, so a thin read is never inflated and a hull is never credited a “safe 0” for a signal it has no row for. Higher means riskier. Derived in-house from government-open port-State-control, flag, sanctions and our own vessel data; weight it by the coverage above.

Estimate only — modelled from deadweight (hull geometry) using a first-principles hydrostatic model, not measured hydrostatic tables. The design draught it is anchored to is unreliable across the fleet.

The declared type conflicts with the class implied by the vessel’s size signals — a possible mis-declaration. Inferred via our shared size-based classifier.

Method: declared type vs size-implied class (DWT/GT density + beam/LOA fullness). Source: vessel_type_audit (sibling P3#3 job; shared coarse_class classifier).

Signals are a current-state view: a flag clears once the vessel stops tripping its detector. These are screening indicators, not a substitute for your own due diligence.
