IAC has won a major new contract to supply special acoustic enclosures for Indian Navy frigates. In addition to containing the noise emissions of the Wärtsilä diesel generators on board each new vessel, the enclosures have an exceptionally lightweight design and are fully able to withstand severe shock loadings - both essential features in a military environment. Rapid, all-round access to the diesel generators is another key requirement. IAC has therefore developed an ingenious new captive sliding assembly to support all of the enclosure's sidewall panels, allowing them to be removed and stowed safely to one side in just a few seconds.
IAC's track record in marine enclosure design and fabrication was a major factor in securing this latest order, accor4ding to the company. It has produced similar structures for numerous military vessels, including Royal Navy Type 23 frigates. In common with previous projects, IAC has worked closely with several different international organisations to reach a viable technical and commercial solution. They include Wärtsilä (Denmark and India), the Indian Navy itself and Mazagon Dock Ltd in Mumbai, where the new frigates are being built.
