Taken the manhole cover and the surrounding hull structures as the research objects,the typical analysis model including the manhole and the manhole cover was established in the cargo hold model of the bulk carrier.According to the stress state of the manhole cover under the load cases of HCSR,three main factors including the manhole cover,the connecting plate and the bolt connection were compared and analyzed.The research can provide a theoretical bases for the selection of the manhole cover.
