ABSTRACT:
A method of providing a suspended ceiling in a storage tank involves building a deck on the floor of the storage tank and raising it into place by using an external hoist mechanism. The hoist mechanism is connected to the deck by cutting holes in the roof of the tank and feeding cables through the holes. The cables are attached to a series of extenders, such as metal bars, that are fixed to lift points on the deck. The extenders are long enough so that, once the ceiling is raised to its final position, portions of the extenders project into the holes in the roof. The ceiling is then fixed in position by securing the extenders to the roof. After the ceiling is secured in position, the holes in the roof are sealed.
