ABSTRACT:
A dry dock having flotation chambers on two opposite sides of the load-carrying platform is submerged by flooding the flotation chambers. A reversible air pump is used to raise the dry dock by first blowing water out of the chambers then sucking water from the platform into the chambers and then again blowing water out of the chambers. The structure of the dry dock allows it to be used also as a submergible barge.
