Burmeister & Wain Scandinavian Contractors A/S (BWSC)
INNOVA was selected by Burmeister & Wain Scandinavian Contractors to design and supply the structural steel, acoustic envelope, and acoustic building ventilation system for Caribbean Utilities Company’s 24 MW diesel power plant project in Grand Cayman, Cayman Islands.
Acoustic building designed to achieve:
63 dBA at 61 m (200 ft.)
INNOVA’s proprietary acoustical assemblies formed the walls and roof of the power plant. The assemblies consisted of layers of acoustical and barrier materials covered by a metal exterior. The layers were applied onto a structural steel frame and built to withstand sustaining winds of 150 mph (240 km/hr).
INNOVA also supplied the acoustical ventilation system with air flow of 300,200 cfm (510,000 cmh). To limit noise breakout from six ventilation openings, INNOVA custom-designed acoustic plenum chambers to line the openings. Two additional acoustic plenum chambers were constructed around the combustion air intake openings; an acoustic ridge vent (gravity ventilator) silenced noise emissions from the roof ventilation exhaust.
INNOVA also supplied a 33-ton crane for equipment removal and installation.
UNIQUE PROJECT HURDLES
INNOVA designed the plant to be expandable. The plant has two engines producing 24 MW of electricity with room to add an additional 12 MW engine. To accommodate three more engines in the future, a removable end wall was designed into the building’s structure.
