Nigerian pirates have targeted a Valles Steamship tanker hundreds of kilometres offshore, in another reminder of the serious threat to shipping in the Gulf of Guinea.
Security consultancy Ambrey said the 48,600-dwt Seafrontier (built 2011) reported a suspicious approach by a skiff on Tuesday.
The MR tanker was 164 nautical miles (304 km) south-west of the Agbami floating production, storage and offloading unit, in international waters.
