OSLO, July 2 (Reuters) - Pirates attacked an oil production
vessel off Nigeria in the early hours of Thursday and kidnapped
nine Nigerian nationals, the ship's owner BW Offshore BWO.OL
said.
The Sendje Berge ship was undergoing maintenance when the
attack happened, BW Offshore's Chief Financial Officer Staale
Andreassen told Reuters.
The Oslo-listed company said none of the people remaining on
the vessel were injured.
"We are working now with the Nigerian authorities to get
those nine people safely back," Andreassen added.
The vessel, a floating production, storage and offloading
vessel (FPSO) that can produce about 50,000 barrels per day, was
working at the Okwori oilfield operated by Addax Petroleum, a
part of China's Sinopec Group.
A maritime security firm Dryad Global, citing unidentified
reports, said the attack involved three boats and explosives,
making it unusual.
Andreassen said he could not confirmed that a number of
boats had been involved, but denied that explosives were used
during the attack.
