선박용 Bilge water 처리 장치의 압력용기에 대한 구조 건전성 평가
Abstract
This paper presents the structural integrity evaluation of a pressure vessel for a bilge water treatment device for ships. The device incorporates a nano-micro filter, a cutting-edge technology replacing conventional filters. This filter is expected to reduce the oil content in the bilge water to less than 5 ppm. A stress analysis was conducted by considering the increased back pressure applied to the pressure vessel owing to the implementation of the new filter. The structural integrity of the device, which is crucial for its safe and effective operation, and its performance were evaluated using a numerical analysis based on the ASME code. All the stress classification lines satisfied the criteria specified by the ASME code, ensuring the structural soundness of the pressure vessel. This study contributes significantly to the ongoing global efforts to prevent marine pollution by effectively treating bilge water onboard ships.
