Horton Shallow Water Development's (SWD) CX-15 buoyant tower has been set as planned for BPZ Energy off the coast of Peru. The Buoyant Tower concept draws on the proven technology of the cellspar and the design provides multiple benefits for fields where other concepts would be problematic requiring high capital costs and expensive crane barges for installation. The design allows for oil storage if needed, can eliminate separate shallow water drilling units and provides a high level of flexibility for the operator.
