ESC was commissioned by a major construction company in South Korea to carry out an Acoustical Induced Vibration (AIV) & Flow Induced Vibration (FIV) studies for their project Saudi Aramco Marjan Package 12 in 2020.
About the Project
As part of Package 12, Saudi Aramco plans to develop a new utility plant that will supply electricity and water to an onshore plant that processes 2,500 million standard cubic feet of gas per day. The new plant will be located near Marjan, Saudi Arabia.
As part of the design and construction of the new facility, the client sought ESC’s Noise Specialists to undertake a noise study to assist in the design process for the facility to achieve compliance with the project noise limits within the site boundaries.
Delivery of a high-quality outcome requires the input of personnel with experience in assessing and managing noise emissions from a range of sources while working in a collaborative manner with project architects and other stakeholders to ensure consideration of all factors influencing the design.
The approach involves several stages of preliminary noise study which include:
- noise limits specified for both plant areas and off-site areas
- allocated equipment source noise levels adopted for the study for inclusion in equipment supplier tender documentation
- evaluation of predicted noise levels in the environment, work area and on-site buildings including a description of the compliance of predicted noise levels with the plant noise limits
- Noise contour plots for individual plant areas for both normal and emergency operational scenarios
- list of equipment requiring specific acoustical insulation, silencers and/or enclosures to meet the specified noise limits
- description of the results of the noise study including identification of any hearing protection restricted areas identified by the predictions.
The preliminary noise study took into account the potential noise implications related with emissions during both normal and emergency operations. The analysis specifically evaluated the possibility of project noise limitations being exceeded both in the plant area and within buildings.
