Offshore oil & gas facilities are noisy places where the workers live and work for extended periods of time. For health and safety reasons, as well as quality of life, each employee’s living areas should allow for a much needed respite from the high noise levels generated during continuous daily operations. A detailed review of the vibro-acoustic noise levels will help to reduce the stress of continual exposure to high noise levels to prevent hearing loss or other potential health issues. The Statistical Energy Analysis (SEA) method represents a "high frequency" modeling technology for evaluating vibro-acoustic behavior over a broad range of frequencies. In application to offshore oil & gas facilities, this robust mathematical type of analysis is effective for evaluating noise over the entire audible frequency range. SEA is effective for modeling complex structures with many sources and energy paths. In this paper, the structural-acoustic propagation from multiple sources was considered. A SEA model was developed to predict the vibro-acoustic propagation from significant source locations that impact a worker’s living quarters. The SEA model is used to predict the structural-borne noise levels within living areas to evaluate potential design changes for improvement to the acoustical environment.
