Abstract: The present embodiments provide systems for cleaning NORM scale or other contaminants off of one or more objects via a laser. The laser can be moved through a pipe or around one more containers. This avoids the use of water to remove NORM, thus the present systems are more environmentally friendly than conventional cleaning systems.

Abstract: A process to remove impurities from a surface of a cargo tank of a vessel used to transport liquid hydrocarbons includes using an active chemical solution to dissolve at least a portion of the impurities or the matrix in which they are embedded deposited n the surface of the cargo tank. The process also includes allowing the active chemical solution to subsequently remove embedded impurities from the surface.
