In September 2004, Hurricane Ivan passed through the Pensacola area resulting in extensive damage and loss of power at the Naval Air Station (NAS) and related facilities at Corry Station and Saufley Field. The government responded with a comprehensive project to harden the utility infrastructure at these facilities, including the installation of a new SCADA system for electric, water and wastewater utilities. The new system was to have included relocation of master station facilities to a more secure and hardened location, replacement of the existing hardwired communications system with a wireless network less prone to damage from winds and flooding, and a complete replacement of all hardware and software, including RTUs for a more useful and up-to-date system.
Burns & McDonnell provided the initial Needs Assessment and Feasibility Study for the project. We were then retained to perform the radio path and coverage analyses for the wireless network, and provide complete system specifications for a turnkey project. Burns & McDonnell served as owner’s engineer throughout the design and construction of the system, and provided testing and inspection services.
The new system includes 73 new RTUs at electrical substations, water treatment, storage, and distribution facilities, and wastewater collection and treatment facilities. The communications network includes licensed 420 MHz point-to-multipoint systems, and unlicensed 900 MHz wireless Ethernet. The new master station includes a dual-server system with two control centers; one at NAS and a second at Corry Station.
