In order to have easy access to these cabins, a manhole cover must be provided. The purpose of setting the manhole cover is for the construction and maintenance personnel to enter and exit. Once the operation completion personnel leave, the manhole cover should be closed.

The manhole cover is a kind of outfitting equipment, which is installed on the manhole opening of the oil tank, empty space, etc. of the ship, and is mainly composed of a cover plate with very good sealing and some fixed accessories.
