MSCI Advisory

2023-008-Gulf of Guinea-Piracy/Armed Robbery/Kidnapping for Ransom


This revised advisory cancels U.S. Maritime Advisory 2023-001

1. Reference: None.

2. Issue: Piracy, Armed Robbery, and Kidnapping for Ransom (KFR) pose significant threats to U.S. flagged vessels transiting or operating in the Gulf of Guinea (GoG) as well as U.S. mariners onboard a vessel or transiting to or from a vessel in the GoG.

3. Guidance: During the last six months, pirates, armed robbers, and KFR groups are known to have operated off Nigeria, Gabon, Ghana, Ivory Coast, and the Republic of the Congo. During this period, they targeted a variety of vessels to include tankers, container ships, general cargo vessels, and passenger vessels. These groups have boarded vessels up to 300 nautical miles from shore, and it is not uncommon for these groups to fire upon vessels during boardings and attempted boardings. KFR groups generally kidnap senior crew members, including the master and chief engineer, and any Western or foreign crew members. Kidnapped crew members are normally taken ashore in the Niger Delta region where KFR groups demand ransom payments in exchange for the safe return of the crew members. Details of incidents in the GoG can be found in the Office of Naval Intelligence Worldwide Threat to Shipping reports, posted at 

Two kidnappings for ransom and one hijacking since January 2023 represent an increased threat to maritime security in the GoG. In March, six crewmembers were kidnapped from a Liberian-flagged tanker approximately 140 nautical miles off Pointe Noire, Republic of the Congo, and in May, three crewmembers were kidnapped from a Marshall Islands-flagged bulk vessel in Owendo Anchorage, Gabon. Both abducted crews were released safely, likely after ransom payments were made. These crews were held captive for almost 6 weeks and 3 weeks, respectively. In April, a Singapore-flagged bunkering tanker was hijacked approximately 300 nautical miles south of Abidjan, Ivory Coast. The hijacked tanker and crew were released five days later, after the vessel’s cargo had been stolen.
