Title (EN) ROTATING PONTOON
(FR) PONTON ROTATIF
Abstract:
(EN) A pontoon shaped as a large floating cylinder with a hollow interior, receiving one or more vessels (21) can be overturned through its rotation. The walls of the pontoon are made up of watertight compartments (1-21) which provide floatation and enable rotation of the pontoon. Rotation of the pontoon can be achieved by displacing water (Figs. 20-24) successively from one peripheral watertight compartment to another (Figs. 1-6). This rotation can also be performed by means of external power (Figs. 26-30). An external platform (45) is attached to the pontoon through joints (42), keeping its normal upright position when the pontoon rotates. On the platform can be installed the engine room (53) as well as all the implements used to perform the pontoon anchoring, towing, and mooring. This accessory equipment can also be attached to a belt (66) surrounding the pontoon hull and fastened to stationary floatation tanks (79). To provide for the discharge of vessels in rainy days, two types of floating roofs (49) are disclosed. To remove the load fraction which remains inside the vessel holds after its overturning, a system of pushing panels (Figs. 7-9) inside the hold and a system of helicoidal hatch-feeders (35-36) are disclosed.
(FR) Ponton presentant la forme d"un cylindre flottant creux de grandes dimensions, et dans lequel viennent se loger un ou plusieurs recipients (21) qui peuvent etre bascules par rotation du ponton. Les parois du ponton sont constituees de compartiments etanches (1-21) qui donnent au ponton sa flottabilite et permettent sa rotation. La rotation du ponton peut etre effectuee par deplacements successifs de l"eau (figs. 20-24) d"un compartiment peripherique a un autre (figs. 1-6). Cette rotation peut egalement etre effectuee en utilisant une energie externe (26-30). Une plateforme externe (45) est fixee au ponton par l"intermediaire d"articulations (42) et conserver sa position normale lors de la rotation du ponton. On peut installer sur cette plateforme la chambre des machines (53) ainsi que le materiel necessaire pour proceder a l"ancrage du ponton, a son remorquage et a son amarrage. Ce materiel accessoire peut egalement etre fixe sur une ceinture (66) entourant la coque du ponton et assujettie a des bacs flottants fixes. Deux types de toits flottants (49) sont egalement prevus pour faciliter la decharge des recipients par temps de pluie. Pour vider la fraction de la charge qui est restee dans le recipient apres son basculement, il est prevu un systeme de panneaux de poussee (figs. 7-9) dans la cale ainsi qu"un systeme de transport a vis helicoidales (35, 36).
