"Armed attacks against ships in the oil-rich Gulf of Guinea surged in 2018, making these waters off West and Central Africa the world's most dangerous for piracy and armed robbery. The escalation confirms the Gulf of Guinea's status as the main locus for maritime insecurity in Africa, which had long been associated with the Horn of Africa, particularly Somalia. Rising piracy and armed robbery in the Gulf of Guinea likely reflects the region's growing prominence in global maritime trade, as well as capacity and coordination gaps among many of the region's navies."
