Buoyant tower platform set on Corvina field

The buoyant tower drilling and production platform for BPZ Energy’s Corvina oil field has been set offshore Peru (OGJ Online, Aug. 7, 2012).

The CX-15 platform, called the world’s first such structure, was installed in 175 ft of water 1 mile from the existing CX-11 platform, reports Horton Shallow Water Developments, the designer.

The hull was floated horizontally from the Offshore Heavy Transport Osprey heavy-lift vessel, which carried it to the location from the construction site in Nantong, China, and upended with a controlled flood. The hull took on additional ballast before mating of the topsides.

The platform can support production of 12,200 b/d of oil and 12.8 MMscfd of natural gas. It has produced-water handling and injection capacity of 3,500 b/d.
