Royal Boskalis Westminster has revealed one of its heavylift ships was hijacked off Africa on Sunday — but has now been freed.

The company said the 76,000-dwt Blue Marlin (built 2000) was seized 80 miles off Equatorial Guinea.

"Through the professional response of the crew and the coordinated support from the navy of Equatorial Guinea and Spain, the violent hijacking has been ended and the crew was safely freed," it added.
