QatarEnergy has instructed all vessels approaching Ras Laffan Port to switch off
their automatic identification system (AIS) “within the port, anchorages, and
port waters” until further notice. The order follows Iranian attacks in March
that damaged roughly 17% of Qatar’s LNG export capacity, with repairs expected
to take up to five years. Before the directive, around 40 ships were
transmitting positions; by Tuesday, only one vessel remained visible, according
to a company advisory.
