The Marine Derrick Test Tool Design and Optimization

In this paper, aim the circumstances of derrick and substructure for a specific offshore platform, two derrick test tools be devised, The substructure and the test tool model established and assembled by Workbench software, and through the ANSYS finite element analysis software calculated the substructure and the test tool, then based on the analysis in contact with the forces condition of the test tool that were optimized. By comparing the test tools can be found, the test tooling option II that the weight, the forces condition and operation is better than another one, so when the conditions to meet the circumstances, option II is recommended to use. The design ideas and methods for test tool design and manufacturing provides a useful reference.
