As its names suggests, versatility was one of the main aims of the Versatank. One tank to rule them all.  As such the tanks would need to satisfy the rigorous demands and requirements of almost any use or industry. At the same time be light enough when empty to be easily handled and maneuvered and also strong enough to be easily and safely lifted into any required position with the use of appropriate shackles and strops prior to filling. All this at an advantages price point.
