DEFINITION

Classification: 114/45

Means for raising vessels by use of semi-submergible docks, nearly all of which are floating vessels and constructed to receive the vessel upon its bottom or upon a platform or equivalent way, the dock being raised by changing the line of flotation through buoyancy by ejecting or pumping water from the water-tanks or by changing ballast.
