The platform can support production of 12,200 barrels per day of oil and 12.8 million standard cubic feet per day of natural gas, both firms said. In addition, it can support a drilling rig with 24 well slots

A Chinese oil and gas firm has announced the successful load out and sail the world’s first Buoyant Tower drilling and production platform to be used by a US energy company for exploration offshore Peru, both firms said on Monday.

The CX-15 platform was completed and delivered to House-based firm BPZ Energy at Wison Group subsidiary, Wison Offshore & Marine Ltd's construction site in Nantong, China. It cost USD 77m and was constructed in 11 months.

The Buoyant Tower hull for the facility consists of four, ring-stiffened connected cylindrical tubes with one central suction pile. Each cell measures 8.4m in diameter and 60.1m long. Total hull length is 69.9m.

The platform can support production of 12,200 barrels per day of oil and 12.8 m standard cubic feet per day of natural gas, both firms said. In addition, it can support a drilling rig with 24 well slots.

The CX-15 platform is en route to the Corvina oil field operated by BPZ Energy offshore Peru. CX-15 will be installed in Peruvian waters in September 2012 and connected through a pipe to BPZ’s neighbouring CX-11.

“The new CX-15 platform and hull...will be installed shortly at our Corvina field in Block Z-1,” COO at BPZ Energy Richard Spies said. “The importance of this design is that it allows us the ability to develop other future discoveries that are located between 200 feet and 700 feet of water.”

The Corvina oil and gas field is situated in the offshore Block Z-1 in the shallow waters of the Tumbes Basin, northwest Peru. Its estimated proved SEC reserves stood at 27.8 million barrels of oil at year-end 2011, according to BPZ Energy. It was first estimated in 2006 to contain more than 3 trillion cubic feet of proved, probable and possible natural gas reserves.
