Abstract

A feeding raft for a net cage installation is described, comprising a floating raft (10) moored adjoining one or more net cages for farming of marine organisms, with the raft (10) comprising a number of silos for storing of feed material that shall be distributed to said net cages. The raft comprises a first, centrally placed silo (14) and, at least, a second, at least partially surrounding silo (16).

Description

Feeding float for a fish farm
The present invention relates to a feeding raft for a net cage installation, comprising a floating raft moored adjoining one or more net cages for farming of marine organisms, with the raft comprising a number of silos for storage of feed material that shall be distributed to said net cages.
Net cage installations are being moved more and more out from fjords and out to the open sea. This results in stronger demands on net cage installation, feed rafts and other associated equipment to be able to withstand the rather large strains that they are subjected to under difficult conditions. This can be weather conditions, waves and ocean currents.
It is an object of the present invention to provide a feed raft that gives a better stability to meet the above mentioned challenges and at the same time offer a better storage space for the feed material.
A big problem with all rafts that have been produced up until now, is rolling at different removal and filling of feed material from different silos. There are comfort issues and problems with bending of feed pipes and also that the silo is more complicated and more difficult to fill from a feed boat. The new solution has a central manifold with pipes down to concentric silos that makes the raft less susceptible to rolling and this provides a better comfort and less strain on the feed pipes in waves. A bend on a feed pipe can stop the feeding of the fish. This solution also offers a better degree of filling in the raft.
From prior art, NO 306321 and NO 0179431, among others, shall be mentioned, and which both relate to floating feeding rafts with silos for storage of feed material.
The above mentioned objects are reached with a feed raft as defined in the independent claim 1, in that the fleet comprises a first, centrally placed silo and, at least, a second, at least partially surrounding silo.
Alternative embodiments are disclosed in the dependent claims 2-7.
The first central silo can have a circular-cylindrical shape and the second silo can be, at least partially, ring-formed.
A filling manifold for feed material can be arranged above the mentioned silos, arranged to distribute feed material to respective silos. The filling manifold is preferably controlled by valves and arranged to distribute the feed material received from a feed boat via a number of downwardly extending feed pipes to the respective silos.
A number of feed pipes for the feed material are preferably arranged adjoining the bottom of the raft to receive feed material from respective silos and arranged for blowing the feed material to the respective net cages. Said feed pipes can be suspended on the outside of the raft with clamps, elastically mounted in a rack.
At least the bottom part of the raft can have a circular- cylindrical shape and be equipped with means for buoyancy.
The invention shall now be described in more detail with the help of the enclosed figures, in which:
Figures 1-5 show a feed raft according to the invention.
Figure 6a shows a silo arrangement according to the invention.
Figure 6b shows in more detail the filling manifold shown in figure 6a. Figure 7 shows suspended feeding pipes according to the invention.
Figure 8 shows the silo arrangement with associated equipment according to the invention.
Figure 9 shows a feed pipe arrangement in the bottom of the raft according to the invention.
As the figures show, the feed raft comprises a raft (10) that floats on water and which can comprise a wheel house, cabins for the crew, living quarters, equipment for the operation, store room, feed material silos, and general equipment to operate the feed raft and the associated net cage installations (not shown) . The feed raft is moored with the help of anchors and chains in the usual manner.
Figure 3 shows unloading of equipment and goods, while figure 5 shows a feed boat that delivers feed material to the feed raft 10 via an outrigger 30 to a preferably central, filling manifold 18 on the feed raft 10. This manifold 18 is controlled by valves, for example, with the help of one or more electromechanical, hydraulic or in any other way controlled valve leaves, to deliver feed material via filling pipes 20 to the respective silos.
To obtain the improved stability, the feed raft 10 is equipped with a number of silos, where- a first silo 14 is placed centrally in the raft 10 and has a circular- cylindrical shape, while at least one other silo 16 is arranged around the first silo 14 as shown in the figures 6a and 8. Thus, the second silo 16 can have a circular- cylindrical ring shape and surround the first silo completely, or partially. The second silo 16 can be divided into several chambers, where each chamber receives feed material via a respective filling pipe 20.
Externally to the second silo 16, several silos can be arranged (not shown), also preferably with a ring shape.
As shown in figure 8, an outlet for feed material via feeding pipes 22 that run out of the raft 10 to the net cage installations, is arranged in the bottom 12 of the raft 10. Because of sea swells and strains, the feeding pipes at the transition between the raft and the sea are preferably mounted in a clamp 26 which, with the help of elastic elements 28, for example, springs, is in turn mounted in a rack 24, as shown in figures 5 and 7.
The bottom of the raft 10 is preferably formed in a circular shape and is equipped with means for buoyancy, as shown in figure 9. This leads to considerably improved' seaway characteristics for the raft 10.
In the above description only the main principles with the solution are included while details have been left out.
