PROJECT DESCRIPTION

INNOVA was selected by Black & Veatch to design, supply and erect an acoustical steam turbine generator building to meet near and far field noise target objectives and a structural requirement for quick removal near Parrish, Florida.

Owned by FPL Group, and operated by Florida Light and Power, the Manatee Power Plant was originally established in the 1970s. At the time, planners set aside a 9,500-acre site to provide for expansion purposes.

Initiated in 2003 by Florida Light and Power, the $600 million Manatee Power Plant addition is one component of a larger expansion plan. The Manatee Phase 1 expansion, completed in mid-2005, added a new natural gas-fired 1100 megawatt combined-cycle generating unit.

SCOPE OF WORK

The acoustic wall and roof assemblies were designed to be decoupled from the building structure to eliminate structural borne vibration and noise. In addition, INNOVA designed, supplied and installed the new building’s ventilation system (wall-mounted inlet fans and passive relief weather hoods) and electrical components (lighting, lighting protection, emergency lighting and all conduit and wiring). 

ACOUSTICAL REQUIREMENTS

The far field target was 60 decibels (A-weighted) at 122 meters in all directions. Sound pressure levels were not to exceed 85 decibels (A-weighted) at 3 ft. from the enclosure and 5 ft. above pedestal level.

NOISE SOURCES

One (1) Toshiba Steam Generator Unit

UNIQUE PROJECT HURDLES

The building was erected on the steam turbine pedestal which is 40 ft. above grade. During construction, four hurricanes reached the plant site, stopping work and refocusing Florida labor on clean-up and restoration.

RESULTS

The project was completed over five months during 2004 and 2005.
