A study of the development of a new type of bulb bracket for offshore structures using suitable casting steel

In this study, the optimum structural design of brackets for offshore structures was carried out through the ANSYS program. We wished to propose a new type of bulb bracket made by a casting process compared with the built‐up type of bracket. For a better structural design of the bracket, we can’t adopt face plate but stiffener and circular type shape at the diagonal surface line. Under the new type of bulb bracket made by a casting process, it was possible to reduce the size by about 30% and the weight by about 50% compared with the face‐plate type of bracket.
