Nigerian Chief of Naval Staff Admiral Ganiyu Adekeye said that investigations were on to identify the whereabouts of the oil workers with the Royal Dutch Shell kidnapped by unidentified armed militants, state media reported on Thursday.
Adekeye stated that as soon as the hideout of the kidnappers was identified, the workers kidnapped from a flow station in the Bayelsa state operated by Shell would be rescued, according to the official News Agency of Nigeria.
He, however, declined to give further details as he said solders deployed to comb the troubled oil-rich Niger Delta for the rescue operation.
Shell had announced the shut in of production at the 120,000 barrels per day EA offshore field and the withdrawal of non essential service personnel on the field's floating production storage and offloading vessel, the Sea Eagle, which is moored some 16 km offshore in water depths of about 25 meters.
The kidnapping occurred on Wednesday afternoon when armed men, riding in three boats, stormed the vessel. A Shell spokesman said the four were a Honduran, a Bulgarian, a Briton and an American.
