SIYANIE SEVERA

Stopped, anchored or moored on its latest broadcast: parked, not necessarily withdrawn.

Read from the single most-recent AIS broadcast we hold for this hull. We keep no position history, so this is a point-in-time posture, not a dwell inference. Derived in-house from our own AIS feed; weight it by the broadcast age above.

Strong, corroborated adverse evidence: a detention, sanctions exposure or an AIS-gap / behavioural signal.

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.
