2. Page  2 Introduction  MobiDick is a testbench used to provide full certification of the super-drawers during maintenance periods  The system is currently in its third version, and the goal is to have a new version ready for the long shutdown, in 2013  Motivation: it should be smaller and lighter, while using new technologies. It will provide better mobility and make the system more reliable
