A helideck is a very valuable offshore structure for the take-off and landing of a helicopter. In order to design a helideck, the designparameters and various loads defined by the regulations related to the design of a helideck should be applied. In this study, a risk analysis wasperformed based on the helicopter accidents for seven years, and the frequency and possible reasons for accidents involving helidecks wereinvestigated. In addition, a finite element analysis of a steel helideck mounted on the upper deck of a ship (shuttle tanker) was performed with theload that should be considered when designing a helideck. Based on the results, a parametric study of helideck was carried out by applying avariety of design parameters, and an improved helideck design was presented. This improved helideck reduced the steel used by up to 24%compared to the initial helideck design, and the results of a finite element analysis were analyzed and compared with those of the initial analysis.
