BW Offshore's floating production storage and offloading (FPSO) vessel BW Adolo produced first oil on 16 September, 18 months after the initial investment made in the Dussafu license offshore Gabon.

"We have achieved first oil from the Dussafu license within budget and on schedule," said Carl Arnet, chief executive of BW Offshore.

"The execution of the Dussafu project confirms the attractiveness of our model by combining proven resources, a resourceful organisation and access to production assets to achieve short time-to-oil."

The 299,900-dwt BW Adolo (built 1988) arrived in Gabon in late July and hook up of mooring systems and installation of risers and umbilicals were completed in September.

The project was safely completed without any harm to people or the environment, the Oslo-listed FPSO operator said.

The FPSO is installed on the Tortue field, one of five proven discoveries in the Dussafu license.

The BW Adolo is a converted VLCC with a production capacity of 40,000 barrels of oil per day. The vessel has undergone an increased life extension scope enabling an extended production profile on the back of positive reserve developments.

"Our first priority now is to complete start-up activities and stabilise production on BW Adolo," Arnet said.

"We will at the same time work towards the final investment decision on Tortue Phase 2, which will unlock additional production volumes, and continue the appraisal program of the recently announced discovery at Ruche NE as well as to confirm additional resources and strengthen the commerciality of the Dussafu license."
