An AP Moller-Maersk containership crew has frustrated the latest pirate attack off Nigeria — twice.

The 4,496-teu Maersk Cardiff (built 2013) was approached by a small craft on Wednesday evening, 150 nautical miles (278 km) south-west of Bonny, according to security consultancy Dryad Global.

"The crew have mustered in the citadel. The [approaching] vessel left and the crew and vessel are safe," it said.
