Abstract

The present invention provides a method for controlling a platform floating on a water surface, the platform comprising a base for receiving buoyancy tanks from below with interposition of connection means, and at least n buoyancy tanks, n-1 tanks being capable of supporting the base, characterized in that it comprises the following successive steps to check the integrity of at least one of the at least n buoyancy tanks at a remote site: at least one caisson is filled with floating water until equilibrium with a depression larger than the other caissons.

Description

Control method of water surface floating platform

Technical Field

The present invention relates to a method and apparatus for maintaining a floating platform, particularly a platform for residential and office structures supporting offshore platforms.

Background

The existing structures which are to float and are positioned on water bodies and rivers do not allow the structures to have navigation capacity due to the draught or the size of the structures and navigate in the area of a water channel. In addition, bridges in water may prohibit the passage of structures at a certain height, and the curves of some rivers may be too narrow. Further, the structure made of the ship body such as a waste barge does not change the structure of the building itself and does not provide a sufficient indoor space. In this case, the new hull must be subjected to regular inspections and the use of a large integral boat form platform is not a good solution.

Disclosure of Invention

In one aspect of the invention, the floating platform is made up of connected pontoons, supported in their entirety by a foundation from which a structure is erected which is intended to constitute a habitable space. The advantage of this structure is to allow a completely free installation on the architecture of the installed components. Thus some water areas can accommodate similar structures large enough to enable the structures of the invention to be constructed as restaurants, offices, and can accommodate spaces of hundreds of square meters.

The upright structure of the present invention has the advantage of being floatable and provides all the convenience, including the external landscape. Areas that are not used or cannot be used in conventional building planning can also be used.

The base structure may be made of metal structures, wood structures, or parts of composite materials. The platform is secured in place by mooring systems, docks, piles or underwater anchors.

The method proposed by the present invention suggests a platform and structure in which a sufficient number n of caissons are installed under the floating platform so that the buoyancy of all n caissons minus the buoyancy of at least one buoyancy tank is maintained, with at least one buoyancy tank being removable.

According to the arrangement of the invention, each buoyancy tank comprises ballast means, such as means for introducing water into the buoyancy tank and drainage means and means for connecting the buoyancy tank to the platform.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In fig. 1-3, a floating platform 10 on a water surface is shown supporting a structure 12, the assembly being located on a body of water, such as an ocean, river or water body, indicated by the letter E. The platform 10 includes a base 14, and the structure 12 is disposed on the base 14. The foundation 14 is located on n floating caissons 16-1 to 16-n, the waterline L being determined during the study, so that the position of the maximum immersible portion can be determined. The number n of floating caissons is adapted such that the withdrawal of at least one floating caisson 16 enables the buoyancy of the platform to be maintained and the concavity is still limited. The platform 10 can thus be supported by n-1 pontoons. It is also possible to provide twice the number of tanks as many as n or 2n as required to remove half of the tanks to keep the waterline above the water surface.
