ESTIMATED — implied speed = straight-line distance / dark hours. Actual route unknown. Reference: loaded VLCC ~12-14 kn, ballast ~15-16 kn, stationary <1 kn = possible STS or anchorage.

Loitering Events

60 events, 830 hours total (stationary at sea — possible STS transfers)

P&I Insurance

No entry found in American P&I — coverage not determined

Only American P&I could be queried. The International Group's combined ship search (the other 12 clubs) blocks automated lookups, so those were not checked. Absence here is not evidence that the vessel is uninsured.
