METHOD OF SHIP MOTION AND SHIP MOVED BY PROPOSED METHOD Russian patent published in 2011 - IPC B63B1/34 B63B3/18 

FIELD: transport.

SUBSTANCE: proposed method relates to pontoon-type-hull-ship with outer plating with simplified hull lines, flat inclined bottom sections in end on, propulsors and power plant. In compliance with proposed method, relation between hull width B and length L is selected proceeding from condition B / L>0.14. To reduce front wave resistance, floatable streamlined pontoon is arranged at bow end on. To allow free flow of water through the ship, inclined shaft is made behind aforesaid pontoon from ship deck to bottom. In motion, outer plating is displaced over ship surface and moving pontoon along water flow with speed comparable with that of water flows except for friction resistance. Water is forced to ship end on to reduce wave resistance. Air pressure is continuously maintained on plating inner side to prevent ingress of water onto plating inner surface. Proposed ship comprises displacement hull with outer plating, simplified lines, flat inclined bottom sections, propulsors and power plant. In compliance with proposed method, relation between hull width B and length L is selected proceeding from condition B / L>0.14. To reduce front wave resistance, floatable streamlined pontoon is arranged at bow end on. Outer plating is arranged to displace over hull and moving pontoon surfaces along water flows with the speed comparable with that of water streams. Additional compartments are arranged on hull and moving pontoon surfaces and filled with compressed air to prevent ingress of water on outer plating inner surface. Displacing outer plating is provided on outer side of said compartments. Device to displace outer plating made up of belt conveyor is arranged inside each said compartment. Inclined shaft is made between deck and bottom. Shaft walls are formed by hull inclined transom and pontoon sidewall. Additional compartments with displacing outer plating are arranged on pontoon and transom surfaces.

EFFECT: reduced friction resistance and wave formation, better stream-line form, h igher load capacity and stability.
