No, the Armor-Hull component dispenses a very thick, fast-hardening goo-like substance via the pumps seen all over the ship to patch all holes and cracks created by enemy projectiles; even the Balloon component does the same thing to patch tears made in the balloon frabric. The vibrations caused by the impact of the spanner, pipe wrench, and mallet help keep the goo flowing along smoothly. As the ship takes damage, the goo needs to be helped along faster to keep up with the new holes and cracks being made. If the engineers fail to keep smacking the Armor/Hull component, the goo will dispense too slowly and both the armor and hull will be too weak to stop the projectiles from tearing through and destroying the boiler/fuel tank that is always placed directly underneath the Armor-Hull component - The destruction of the boiler/fuel tank leads to the following explosion and then death.
