A vessel operated by Hamburg-based Bernhard Schulte Ship management was attacked by two speedboats in the Gulf of Guinea on Friday.
The Maersk Tema was attacked by two speedboats off the Nigerian coast, a spokesman for Peter Doehle Schiffart and Bernhard Schulte said. The crew followed emergency procedures, but the spokesman did not say whether the pirates had boarded the ship.
The Maersk Group in Copenhagen, Denmark, said that despite the name, it was not one of their ships.
Nine out of 10 maritime incidents of piracy and kidnappings for ransom are reported in West Africa’s Gulf of Guinea, which stretches 5,700 kilometres (3,500 miles) from Senegal to Angola.
