Case Study
Grangemouth Ethane Store
2016
– Project Description
TGE Gas Engineering appointed Clement Acoustics in 2016 to undertake an operational noise breakout assessment of Europe’s largest Ethane store in Grangemouth, Scotland. Proposals were to install new storage plant on a previously unused site.
Our Involvement
The project brief was generally in two parts: to assess the likelihood of any negative impact on residential premises in the area and recommend mitigation accordingly, and to generate ‘noise exclusion’ maps, to identify where site workers would require hearing protection, according to the Control of Noise at Work Regulations 2005.
Due to the complexity of the site, and the number of different noise sources associated with the proposed use, a 3-dimensional noise model was created using proprietary modelling software Cadna A.
The noise map allowed for the accurate prediction of noise propagation from the site to residential receptors some 1.2 km away, as well as around the proposed site itself.
Based on the results of the modelling undertaken, it was found that due to the significant distance separation to residential areas, particular noise reduction measures would not be required.
On this basis, noise exclusion maps were established, detailing what hearing protection should be worn in different site areas. Due to the nature of the site, both typical operations and emergency operations had to be considered.
