Abstract: The transverse web frame in cargo hold area for a very large crude carrier (VLCC) is optimized to propose a topology optimization design procedure for the transverse web frame under complex operation conditions, including the design domain range of the transverse web frame, the screening criteria of the operation condition, the weight coefficient and the constraint condition. On this basis, the topology optimization calculation is then carried out for the transverse web frame in the cargo hold of a VLCC under the multiple operation conditions by using HyperWorks/OptiStruct, finally resulting in the reasonable topology configuration. The results show that this optimization method is effective and feasible to provide a technical mean for the optimization design of the transverse web frame in large oil tankers. It can also provide reference for the topology optimization of other hull structures.
