Two Pirate Attacks Thwarted Off Nigerian, Guinean Waters

Last week, two serious piracy attacks in waters of both Nigeria and Guinea were thwarted, keeping two crews out of the hands of kidnappers, who failed in their attempt to board the ships.
On Thursday, the IMB Piracy Reporting Centre published notice of an armed attack on a tanker underway in the Gulf of Guinea, about 90 nm southwest of Brass, Nigeria. 
The vessel in question was reportedly the 2006-built Suezmax tanker Bouboulina.
The 163,800 dwt vessel continued its voyage to the port of destination, IMB added.
The Greece-flagged tanker is owned by the Greek shipping company Delta Tankers.
According to the security report, armed pirates boarded a tanker under way; the crew retreated into the vessel's citadel, then later came back out and "regained control of the vessel." No crewmembers were hurt and the vessel continued her voyage. The IMB did not specify the manner in which the attackers were repelled. 
Also last week, the IMB reported an attack on an anchored heavy lift vessel in Conakry, Guinea (within the Voluntary Reporting Area for piracy in West Africa, like the Gulf of Guinea).
The report confirmed that, “six armed robbers boarded the ship and "attacked the duty O/S causing injuries and took the second mate hostage. They reportedly proceeded to rob the crew of cash and belongings, then fled”
“The master alerted the port authorities through the ship's agent, but IMB reports that law enforcement responders did not arrive for another hour”.
A Boskalis spokesperson also hinted that the vessel in question was the heavy lift ship identified as Teal, which has since departed Conakry. The report of an injury and a hostage-taking was erroneous, the spokesperson said. 
The maritime security advocacy group; Oceans Beyond Piracy ranks the Gulf of Guinea among the most dangerous areas for piracy in the world, accounting  for about 32 kidnapping incidents on its waters in the year to date alone – nearly twice last year’s annual total.
