Abstract The oil containment boom made by canvas is a kind of typical flexible structure. It will ruin when the towing speed is too fast. Stress and deformation plays an important role in working performance of oil containment boom. Analyses are conducted by finite element software "ANSYS" in this paper. A number of finite element models for a typical oil boom section are built up, selected the different working conditions, to verify structure's displacement, strain, stress and tensile strength under arbitrary wave-to-course angle. This study provides a more reasonable analytical method and gets some useful conclusions which will guides evaluation of oil containment boom system.

Abstract The paper presents an optimization methodology for comprehensive evaluation of a TLP support with multi-megawatt OWT. Design optimization based on principle dynamic properties of a TLP support system is performed, taking consideration of both resonances of rotational excitation frequency of the OWT and the second-order sum-frequency wave excitations. Reasonable engineering attributes verified by performances of the structure are derived with depth variation. The attributes of TLP support are applied in multi-criteria decision making method-TOPSIS for benchmarking of those feasibilities. The results illustrate the effectiveness of proposed methodology in MCDM combining with economical and environmental attributes together.
