Global maritime security in 2021 was defined by an ever-increasing complex web of threat actors, shipping security firm Dryad Global says in its annual review.

Piracy is becoming region-specific, the report said, and confined to West Africa. In South East Asia, where piracy was previously more common, no incidents were recorded last year.

Maritime crime, which primarily involves thefts at anchor or in port, is the most prolific threat facing seafarers, accounting for 76% of all incidents, Dryad added.
