Abstract
Slewing operation involves a heavy loading and high cyclic movements. With no windows for error, operators and engineers need to operate while maintaining the performance of slewing. Sometimes, the strength of a components changes after repaired or modified. Thus, in order to predict the performance and safety of a gangway after repaired or modifies, this paper intended to predict the factor safety of a slewing post for gangway by using combination of experiment and FEA. This study was conducted on an actual slewing that has been repaired and slightly modified. The slewing was tested on load test for up to 14752 Kg and then the stress data was compared to the FEA analysis. For further analysis, FEA was conducted at 34 tons load and the stress was projected using the factor coefficient obtained in the comparison. The findings shows that the slewing is safe to be operated at 34 tones and below as the overall factor of safety is 1.2.
