| Abstract: | A semi-submersible crane/pipe-laying vessel consists of upper hull, several columns, braces and two low attached hulls. Its structural stress is very much complicated under working and sailing conditions. With a direct calculation method, this paper carries out the analyses and discussions of the load mode of global strength, transfer path of main loads and key area for the structural design of the semi-submersible crane/pipe-laying vessel under the various typical working conditions by FEM. |
