METHOD OF LOADING AND UNLOADING HEAVY CARGOES FROM FLOATING CRAFTS Russian patent published in 2009 - IPC B65G67/60 

FIELD: transport.

SUBSTANCE: invention relates to construction engineering. Method of roll-out loading and unloading heavy cargoes from floating crafts onto/from the beach comprises floating craft mooring and seating on sand bottom bed. Prior to every floating craft seating, the sand bed is plough-loosed or the like to form underwater lateral furrows and ridges to reduce the floating craft uplifting force. Ridge pitch is set equal to floating craft hull balance frame pitch. It is possible to divide the said sand bed into identical squares. A present amount of sand is dumped vertically onto every square. Note also that it is possible to lay, under water, the flexible tubular drains for the crafts to seat thereon.

EFFECT: lower costs of sand bed preparation, reduction in floating craft uplifting force in deballasting and reduced floating up time.
