These are narrow ladders used for accessing confined spaces, like manholes, in a vessel.
Marine manhole ladders are used in various scenarios aboard marine vessels and offshore platforms.
What are the primary uses?
- Access to Storage Tanks and Holds: Manhole ladders provide access to storage tanks and cargo holds, especially for inspection, maintenance, and cleaning purposes.
- Access to Machinery Spaces: In a marine context, manholes often provide access to machinery spaces. These could be engine rooms, pump rooms, or any other technical spaces that require frequent or routine access.
- Emergency Access/Egress: Manhole ladders can also be crucial in emergency scenarios, providing an alternate means of access or egress to different sections of a vessel or platform.
- Confined Space Entry/Exit: Manhole ladders are commonly used for entering or exiting confined spaces on board ships or offshore platforms. These might include ballast tanks, void spaces, or other enclosed areas that need to be accessed for inspection, maintenance, or repair.
As with all marine equipment, manhole ladders need to comply with safety standards and regulations set by maritime authorities such as the International Maritime Organization (IMO) or the International Organization for Standardization (ISO). These standards cover aspects like construction materials, safety features, and load-bearing capacities, to ensure the safety of the personnel using these ladders.
