The necessity of decommissioning offshore plants is becoming increasingly important because of aging. Therefore, a proper selection of decommissioning equipment and evaluation of the structural stability is necessary for the efficiency and safety of decom-missioning work. In this research, methods for designing and evaluating the structural stability of a diamond wire cutting saw (DWS), which is one of the major equipment in decommissioning offshore plants, are introduced. Parametric analyses are performed to appro-priately design and evaluate the structural stability. Consequently, stress decreased significantly (from 195.5 MPa to 112.3 MPa in the cutter part and from 168.2 to 110.1 MPa in the arm part) and weight increased minimally (3% in the cutter part and 0.1% in the arm part) from the initial design. Notably, the DWS is considered that appropriate design was performed by selecting proper design variables, design values that satisfied the allowable stress, and minimizing the weight increase.
