Gratings and Walkways
Walkways
Attachment
Check that walkways used to bridge between rig tanks or other rig components are securely attached at both ends to prevent movement following rig up. Walkways must be bolted or pinned in place with no large gaps in the walking surface. Check that sliding walkways have pin systems to hold them in place. Check that walkways installed above working areas also have a safety cable installed if the potential exists for it to be broken loose by hoisting equipment or other mechanical means.
Condition
Inspect all lifting eyes that are used to position the walkway. They should be in good repair. Also, make sure to lift the walkway level to facilitate installation. Look for corrosion and bent or otherwise damaged sections.
Load Rating
Walkways should never be modified to carry loads they were not designed for. Walkways that carry hoses, electrical cables, or piping systems in addition to foot traffic should be designed to provide a clear walking area and be rated for the loads it will carry.
