Cable tray installation in the tank farm
Thread Content
The cable trays in the tank area are laid along the cofferdam. Is it allowed to lay them on the inside of the cofferdam?
It’s possible; the cable tray simply cannot pass through the middle of the cofferdam – it can only cross over it. If the cable tray does pass through the cofferdam, there will be gaps between the cables inside the tray that cannot be sealed, and as a result it’s not possible to prevent materials or liquids from leaking out of the cofferdam. Such materials and liquids will flow out through those gaps in the cables.
