Definitions

• the object of the present invention is to obviate the above drawbacks of vessels provided with floats and to provide a multifunctional and cost price- friendly method and a corresponding vessel .
• the invention relates to a method in which at least two floats separated by one or more intermediate spaces form a vessel which is provided with inflatable elements which, in the inflated condition thereof, fill said at least one intermediate space at least partially.
• the corresponding vessel comprises at least two floats separated by one or more intermediate spaces, and inflatable elements which, in the inflated condition thereof, fill said at least one intermediate space at least partially.
• such a vessel In the non-inflated condition of the inflatable elements, such a vessel has a typical, catamaran-like hull shape defined by the floats and the intermediate space present therebetween.
• the hull shape is deformed as a result of the inflatable elements being partially or completely inflated or deflated.
• the drag of a vessel having a catamaran-like hull shape in water is comparatively low, so that a rapid movement of the vessel can be realised in an advantageous manner .
• a catamaran is unsuitable for use as a hoist platform.
• the invention makes it possible to convert a catamaran-like hull shape into that of a regular - non-catamaran - vessel, the amount of water displaced by the vessel strongly increases, resulting in an increased lifting capacity or deadweight capacity, thus realising desired advantages which render the vessel suitable for use as a support platform or a hoist platform.
• Both hull shapes, viz. a voluminous pontoon on the one hand and the more slender catamaran on the other hand are combined in a vessel, such as a hoist platform, which is provided with the invention.
• the vessel according to the invention may comprise a number of inflatable cushions arranged between the floats of a catamaran, which cushions are retained between the floats after being inflated. Said retained position is in particular realised in such a manner that the cushions completely fill the intermediate space between the floats, thus supplying the additional buoyancy that is required for supporting heavier loads.
• the movable parts enclose the cushions in such a manner that, once the cushions have been inflated, said movable parts are immovably retained in the intermediate space between the floats .
• Advanced embodiments can be dynamically given a shape adapted to the load to be hoisted, for example, so that the buoyancy on the non- hoisting side of the hoist platform decreases rather than increases, thus making it possible to effect a horizontal position of the platform even during the hoisting operation.
• the invention is in particular also advantageously suitable for supporting spans exhibiting an irregular weight distribution, thus making it possible to dynamically remove any objectionable inclinations in longitudinal and transverse direction in a road surface.
• the invention also relates to a possible adaptation of existing floating (hoist) platforms, by which the hull shape is changed, causing the buoyancy to increase - A - or decrease and the drag to increase or decrease during movement ;
• the change of the hull shape or the deformation is a dynamic change, making it possible to maintain a horizontal position of the platform, even if it is loaded unevenly;
• the platform vessel can be transported by road in separate parts to be coupled together, whilst it can furthermore be deployed over water as well as be adapted to the desired use thereof in a cheaper, quicker and more flexible manner;
• the platform can be geared as regards it shape and dimensions to the requirements of the most widely varying range of applications;
• the platform vessel comprises possibilities to measure and adjust the air pressure in the various cushions by means of an air pressure adjusting system. Furthermore it is possible to adjust the required buoyancy distribution or the maximum load by means of said system. In the former case in order to compensate for an uneven weight distribution of the load for the purpose of maintaining the vessel in a horizontal position and in the latter case in order to prevent the vessel being overloaded.
• the platform comprises possibilities to deliver information and programmable instructions to the user, via a display screen and a PC built into the platform, regarding the pressure distribution in the various cushions, so as to adapt the pressure in the individual cushions to the local requirements and maintain said pressure.
• a wheel house 2 and an air inlet provided with a compressor 1 are placed on a vessel or platform vessel V, which is shown in every one of the appended figures 1-8.
• the figures indicated by increasing, odd numbers show respective front views of the hull shape, and in particular the change in the hull shape as the pressure in the initially empty air cushions 3 is gradually increased.
• Numeral 4 indicates the floats, which are coupled via a support platform D, whilst the intermediate space is indicated at T.
• the likewise increasing even numbers show respective longitudinal sectional views of the vessel V, and in particular the change in the position of the inflatable air cushion elements 3 as the pressure therein is gradually increased.
• the inflatable cushions 3 are supported on the underside by an adjustable bottom B.
• the uppermost position of the adjustable bottom is indicated at 5, and the lowermost position of the bottom B is indicated at 6. In the position indicated at 7, the air cushions are completely filled.
