Comparative Safety Analysis of Different Bollard Supporting Structures

Detailed finite element analysis has been carried out for different bollard supporting structures by ANSYS software. From the analysis results, it can be seen that the bollard supporting structures are of adequate strength to take the design load transferred from the mooring rope during operation considering the requirement on strength criteria from IACS, and strength check is performed in accordance with the updated relevant ABS standard. Finally, a comparison of these different bollard supporting structures is made to find out their own advantages from safety and other aspects.
