we don't recommond that we choose the sunken type of manhole cover.it is better to keep it below the exposed deck .the common manhole cover s fitted 60mm above main deck ,it is not good looking ,the crew may trip over it.you can roll the ol drums or other column object on the man deck convently other than carry it,or it can become obstacle. |
