Description
SILO PLATFORM FOR FISH FARMING
Field of the Invention The present invention relates to a silo platform, and more specifically to a silo platform to be used in fish farming installations.
Background of the Invention A feed silo platform is a well known in the art. The platform installations that are not of a catamaran type have a common handicap, as the weight of the stored fish feed is causing an imbalanced load of the installation, depending upon the amount of feed.
Further the marine currents and waves will provoke movements leading to tensile stresses in the installation, whereby the fish farming environment is deteriorated: Moving the installation to new sites is also cumbersome.
From the above will appear that there is a need for a silo platform installation of a type where the drawbacks mentioned above are eliminated or relieved.
Summary of the Invention It is an object of the present invention to provide a new silo platform of a catamaran type for fish farming.
According to an aspect of the present invention, there is provided a silo platform of a catamaran type for use in floating position by fish farming, even in stormy waters, which includes: an anchored primary float; and a longitudinal corbel quay in level with a driveway and gangways for connecting the primary float and at least one secondary float in a fixed distance from each other, wherein the floats, for the purpose of easing the flow of oxygen rich, environmentally beneficial sea water, is placed in such direction that their longitudinal axis coincide with the direction of current, whereby the installation only to a small extent is influenced by currents and wave movements, wherein the primary float, depending upon its width, is divided in a number of internal chambers or silos for the storage of fish feed and for serving as observation chamber, living quarter, equipment raom, generator room, diesel oil, water tanks or combinations thereof, wherein each individual silo chamber extends

From the above will appear that there is a need for a silo platform installation of a type where the drawbacks mentioned above are eliminated or relieved.
Summary of the Invention It is an object of the present invention to provide a new silo platform of a catamaran type for fish farming.
According to an aspect of the present invention, there is provided a silo platform of a catamaran type for use in floating position by fish farming, even in stormy waters, which includes: an anchored primary float; and a longitudinal corbel quay in level with a driveway and gangways for connecting the primary float and at least one secondary float in a fixed distance from each other, wherein the floats, for the purpose of easing the flow of oxygen rich, environmentally beneficial sea water, is placed in such direction that their longitudinal axis coincide with the direction of current, whereby the installation only to a small extent is influenced by currents and wave movements, wherein the primary float, depending upon its width, is divided in a number of internal chambers or silos for the storage of fish feed and for serving as observation chamber, living quarter, equipment raom, generator room, diesel oil, water tanks or combinations thereof, wherein each individual silo chamber extends
2 downwards to the float base, and wherein the float side walls are forming two of the chamber sides and half the chamber bottom, and wherein the buoyancy of the secondary float is sufficient to support the driveway and the gangways.
The silo platform, creating one of four sides in the fish farming enclosure, is preferably constructed from profiled steel plates, and is generally characterised by an underlying floating construction of a catamaran type with a primary float and at least one secondary float being placed at a suitable distance from and parallel to the primary float, the longitudinal float axis coinciding with the direction of the current. Driveway and gangways are interconnecting the floats. The primary float is of a different construction with bigger dimensions than the secondary float and both floats are particularly adapted for its intended purpose. The distance float to float gives room for paired enclosures as for example of dimensions 15x15, 20x20 or 25x25 meter. In the primary float there is arranged a number of inner chambers and silos extending downwards to the float base and where the float sidewalk are forming two of the silo sides and half the silo base. The silo chambers will partly serve for storage of fish feed, partly as observation chamber, living quarter, equipment room, generator room, diesel oil and water tanks as well as central feeding unit.
Because of the important length of the primary float the anchoring points of the mooring hawser will be spaced far away from each other, and this is preventing deformation of the anchoring system as a docking sea vessel can cause this. Because of the silo placement, the weight will provoke an unbalanced load. Each individual silo or chamber that is integrated in the installation itself can have a total load capacity of 100 metric tons or more. Free chambers can be used for other purposes.
The secondary float is of a construction having enough buoyancy for, with the necessary freeboard, to carry the driveway and the gangways, thereby adding the excellent stability in floating position.
Because the floats are placed in the sea in such a way that their longitudinal axis coincide with the direction of the current, oxygen rich, environmentally beneficial sea water is all the time flowing through the fish farming installation so that an accumulation of unwanted elements is excluded.

3 By the silo platform being built in one unit with the fish farming installation, one avoids having to use vehicle bridges between the storage platform and the fish farming installation, this leading to economical, environmental and safety benefits.
A silo platform according to the invention is constructed from profiled steel plates and constructed for application in stormy waters. Because of the compact construction that only to a small extent is influenced by currents and wave movements, all work can be executed under great safety. The excellent stability and buoyancy of the installation opens for the use of support rails for stretching out the nets at the bottom, so that these are kept stationary, approximately in vertical position, thus always maintaining the maximal production volume.
The platform installation is of a compact construction that will ease the towing to other sites and simplify feed loading, feed distribution, feeding and so on, in addition to permit the continual control with the operation of the installation.
