An International Oil and Gas Producer contacted FDI Acoustics Inc. with an urgent request to complete a Noise Impact Assessment (NIA) for an expansion to a 65 MMscf/d sour gas processing plant. The urgency of the project was necessitated by an audit of the application for the project performed by the regulatory approval agency.
The regulatory agency audit found that the original NIA filed was unsatisfactory. The applicant was given fourteen days to resubmit an acceptable NIA or face approval delays and regulatory agency enforcement action. FDI Acoustics was retained to complete the NIA and responded expeditiously with a sound measurement program detailing the sound levels of the existing equipment in operation at the facility site, a key component in the preparation of a Noise Impact Assessment. FDI’s acoustical consultants identified and calculated sound power levels for over 120 significant noise sources associated with the existing facility as part of the project. Sound measurements were underway when the plant experienced an emergency shut-down, causing an unforeseen delay in the on-site data collection.
FDI’s consultants ensured the facility expansion was modeled and prepared the Noise Impact Assessment report following the requirements of the regulatory agency. The project was completed in 10 days enabling the client to meet the deadline imposed by the regulatory agency in spite of the unforeseen events. The regulatory agency accepted the NIA prepared by FDI and granted approval of the expansion for the gas plant.
