Buoyant Tower set off Peru.


The CX-15 buoyant tower designed by Horton Shallow Water Development (SWD) has been set as planned for BPZ Energy off the coast of Peru. The tower is located a mile from the CX-11 platform in depth of 175 feet in the Corvina field in offshore block Z-1. Both platforms will be interconnected via subsea pipelines.

The platform features specific areas that reduced cost and simplified setting. The Osprey, a submersible heavy lift ship, transported the topside and hull tower components of the platform to the field site, launched the tower and was used for mating the decks to the tower. The hull was initially floated in a horizontal orientation and then upended through a controlled ballast of the lower hull cavities. This process was completed in a day. Additional ballast was added to the hull structure before it was mated with the topside positioned on a cantilever structure, also on the Osprey.

Richard Spies, CO0 of BPZ Energy said, "The use of the buoyant tower design has been a key driver in the cost-effective and timely expansion of the development of our Z-1 asset."

The platform is designed for 12,200 bpd, gas compression capacity of 12.8 MMscf/d and produced water handling and injection capacity of 3,500 bpd. A total of 24 drill slots will be available, some for gas and water reinjection wells.
