1/ SUSPICIOUS VESSEL IN KEELUNG HARBOR, 🇹🇼#TAIWAN. SeaLight has been tracking the cargo ship NEPTUNE for months based on its weird behavior: a flag-switching cargo ship that seldom visits ports but frequently encounters other suspicious ships off the coast. It is now tied up in 🇹🇼Keelung Harbor, where its port paperwork says it just came from 🇭🇰#HongKong, even though its own Automatic Identification System (AIS) transponder's tracking signal says it was never there. Tracking from @StarboardIntel shows NEPTUNE has spent the past 14 months just loitering around Taiwan's coasts: drifting offshore for weeks at a time, occasionally encountering other vessels & not calling at a single port outside Taiwan. The closest it came to Hong Kong in that time was about 490 km. In fact, its entire AIS history shows zero visits to Hong Kong. It currently flies the flag of Comoros, a registry the European Maritime Safety Agency rates "very high risk." It has already switched flags from Tanzania, not long after Taiwan itself announced it was scrutinizing that country's registered ships. So what has this ship actually been doing?
