3501541AFLOATINGCLOSEDFISHPENASSEMBLYTechnical field5 The present invention relates to a floating, closed aquaculture pen assembly suitable for fish farming.Background artFish farming in open cages is a cost-effective form of aquaculture. One challenge is that 10 open cages can be damaged, creating holes through which fish can escape. This can lead to unwanted genetic mixing between wild fish and farmed salmon. Norway produces approximately 1.7 million tons of farmed salmon annually. This production means that more than 1 billion salmon are in cages along the Norwegian coast. Considering that the number of wild salmon in Norwegian rivers is estimated to be under 1 million, even a small loss of 15 farmed salmon escaping poses a significant genetic threat to wild salmon. Therefore, it is crucial that the production of farmed salmon is carried out with sustainable technology that minimizes escapes.A significant reduction in the escape of farmed salmon has been achieved compared to earlier times through better control of the open solutions used. However, it is clear that this is 20 probably not sufficient. To further reduce escapes, the use of closed farming solutions in the sea or on land is likely necessary. This could also lead to other improvements in fish health. Today, there are several solutions for sea farming using closed cage systems. In a closed cage, water is pumped in and released through an opening, usually at the bottom. Closed cages are kept afloat by attaching the impermeable sheet to a floating ring. The floating ring 25 will move both vertically and horizontally when exposed to waves. The water volume in the impermeable sheet constitutes a large mass, and the floating ring will, due to the waves, seek to raise and lower the impermeable sheet with the water volume. The attachment of the impermeable sheet and the impermeable sheet itself are therefore subjected to significant forces. The attachment of the impermeable sheet to the floating ring requires the use of 30 shock absorbers. Even with shock absorbers, the fabric is subjected to fatigue fractures, and this type of cage has significant restrictions when they are subjected to waves, limiting their use.Publication NO 348093 describes a closed fish cage with an impermeable sheet resting on a separate, nearly flat fixed bottom. The impermeable sheet is attached with straps or ropes to 35 a ring above the top of the fixed bottom. The fixed bottom is also connected to this ring. In the presence of currents outside the cage, the current can cause water to enter between the 3501542impermeable sheet and the fixed bottom. This will create friction between the impermeable sheet and the fixed bottom, causing damage to the impermeable sheet over time.NO 343717 B1 discloses a new type of fish pen. Affixing one or more insulation panels to the outside of the fish pen improves the thermal isolation and improves stability. A method of 5 insulating a traditional enclosed fish pen is also disclosed.Summary of the inventionAccording to one aspect, it is provided a floating, closed fish pen assembly. The fish pen assembly comprises a bottom sheet. The fish pen assembly further comprises a bottom 10 support element. The fish pen assembly further comprises an attachment arrangement.

This results in a more robust assembly that is better able to withstand waves, currents, and other factors that can cause relative movement between its components, thereby reducing stress and wear.15Another advantage that may be realized in the practice of some embodiments of the described assemblies and methods is the presence of an additional interface between said bottom sheet and bottom support element that further enforces the robustness of the assembly.20Brief description of drawingsWhile various features of the invention have been discussed in general terms above, a more detailed and non-limiting example of embodiment will be presented in the following with reference to the drawings, in which25 Figure 1 shows an exemplary floating closed fish pen assembly;Figures 2 and 3 show detailed views of the fish pen assembly illustrated in figure 1.Figure 4 shows another exemplary floating closed fish pen assembly;Figure 5 is a detailed view of the embodiment of Figure 4 showing an exemplary dead fish collector lowered down into the dead fish collector holder in the center of an internal net; 30 Figure 6 is a detailed view of the embodiment of Figure 4 showing an upper edge of the bottom support element and the connected bottom sheet to the bottom support element by an attachment arrangement;Figure 7 is a detailed view of the embodiment of Figure 4 showing a lower section of the bottom support element and the bottom sheet and their attachment to the main outlet 35 arrangement;Figure 8 shows another exemplary floating closed fish pen assembly; 3501546Figure 9 shows a detailed view of the fish pen assembly illustrated in Figure 8;Figure 10 shows an alternative design of the bottom support element;Figure 11 shows a detailed view of the embodiment illustrated in Figure 10, wherein the bottom support element and bottom sheet are connected to a bottom ring;5 Figure 12 shows another exemplary floating closed fish pen assembly;Figure 13 shows a detailed view of the fish pen assembly illustrated in Figure 12;Figure 14 shows a detailed view of the main outlet arrangement illustrated in Figure 4;Figure 15 shows an exemplary dead fish collector lowered onto and engaged with a dead fish collector holder in the main outlet arrangement; and10 Figure 16 shows a detail of the dead fish collector illustrated in Figure 15 where the dead fish collector is raised from and is disengaged from the dead fish collector holder in the main outlet arrangement.Detailed description15 Figure 1 shows a floating, closed fish pen assembly 1. The closed fish assembly 1 comprises a bottom sheet 3, a bottom support element 2, and an attachment arrangement. When the fish pen assembly 1 is exposed to waves, the bottom support element 2 absorbs forces from the floating arrangement 17. The bottom support element 2 may be made of rigid or semirigid material.20The bottom sheet 3 in Figure 1 is conically pointed, but other shapes and forms may be envisaged, such as flat or egg-shaped. The bottom sheet and the bottom support element have a same geometric shape. A cross-section of the bottom sheet is circular, but may also be polygonal.25A more detailed view of the embodiment shown in Figure 1 is provided in Figures 2 and 3. The attachment arrangement 6 is interposed between at least a portion of the outer surface 3a of the bottom sheet 3 and at least a portion of the inner surface 2b of the bottom support element 2. The attachment arrangement 6 connects the bottom sheet 3 and bottom support 30 element 2. The attachment arrangement 6 as described above reduces or even eliminates the relative movement, and therefore the friction, between the bottom sheet 3 and bottom support element 2. The attachment arrangement 6 also further enforces the bottom sheet and bottom support element by providing an additional interface on the bottom sheet’s outer surface and bottom support element’s inner surface, respectively.35 3501547The bottom support element absorbs the vertical forces, and the bottom sheet is not subjected to the fatigue forces that would be applied to the bottom sheet if it had to bear the forces from the floating ring without the use of the bottom support element. At the same time, the bottom sheet remains stable on the bottom support element and is not subjected to wear 5 from friction against the bottom support element.The outer surface 3a and inner surface 3b of the bottom sheet 3 can be understood as the outer surface and inner surface, respectively, in relation to the center of the floating closed fish pen assembly. The same applies to the inner surface 2b and outer surface 2a of the 10 bottom support element 2. The outer surface 3a of the bottom sheet 3 and the inner surface 2b of the bottom support element are therefore arranged opposite each other.Although separated for visual clarity in Figure 3, a first part 6a of the attachment arrangement 6 is attached to the outer surface 3a of the bottom sheet 3. A second part 6b of the15 attachment arrangement 6 is attached to the inner surface 2b of the bottom support element 2. The first part 6a and the second part 6b are adapted to engage with each other. The first part 6a and the second part 6b form the attachment arrangement 6.In one embodiment, the attachment arrangement is a hook-and-loop fastener arrangement.20According to one embodiment, the hook-and-loop fastener arrangement comprises at least one section comprising hook-and-loop fasteners. The strength and number of sections of hook-and-loop fasteners are chosen such that bottom sheet and bottom support element can withstand wave motions without disengaging from each other, while at the same time25 allowing detachment and re-attachment when required, such as for maintenance purposes.The at least one section comprising hook-and-loop fasteners may be at least one section comprising hooks and at least one section comprising loops. The at least one section comprising hooks and at least one section comprising loops are adapted to engage with 30 each other. The at least one section comprising hooks may either be attached to the outer surface of the bottom sheet or to the inner surface of the bottom support element. The same applies to the at least one section comprising loops, which may either be attached to the inner surface of the bottom support element, or to the outer surface of the bottom sheet.35 In one embodiment the at least one of the sections comprising hooks or the at least one of the sections comprising loops are circumferentially attached to the internal surface of the 3501548bottom support element, and the respective at least one of the sections comprising loops or the at least one of the sections comprising hooks are correspondingly circumferentially attached to the outer surface of the bottom sheet.5 According to one embodiment the at least one of the sections comprising hooks or the at least one of the sections comprising loops are longitudinally attached along the internal surface of the bottom support element, and the respective at least one of the sections comprising loops or the at least one of the sections comprising hooks are correspondingly longitudinally attached along the outer surface of the bottom sheet.10In one embodiment, the circumferentially and longitudinally attached sections form a mesh.In one embodiment, an area of an at least one section comprising loops is larger than an area of the corresponding at least one section comprising hooks.15With reference to Figure 2, one or more side supports 21 are attached to the bottom support element 2. The side supports 21 are further inelastically attached via attachment means 18 to the floating arrangement 17 which, in this example, is a floating ring. The side supports 21 provide support and stabilization to the bottom support element. The side support 21 may be 20 an enforced edge of the bottom support element 2.The bottom support element of the fish pen may be a fabric, sheet or net clamped between a reinforced edge and the bottom disc on the main outlet arrangement. The bottom support element 2 is contained in the floating arrangement 17 and therefore, the largest diameter of 25 the bottom support element is smaller than the floating ring to which the bottom support element is attached.The floating fish pen assembly shown in Figure 2 comprises a pump assembly 19 that maintains an elevated inner water level 14 inside the sheet arrangement 60, which in this 30 embodiment comprises the bottom sheet 3. The outer water level 13 is maintained lower compared to the inner water level 14.

The bottom 10 sheet 3 is supported by the bottom support element 2.A lower section 2e of the bottom support element and a lower section of the bottom sheet 3e is shown in Figure 7. The lower sections 2e, 3e are attached to the main outlet arrangement 10 through an attachment assembly 10e.15The floating fish pen assembly shown in Figure 4 further comprises an internal net 7. The internal net 7 comprises a dead fish collector 9. The dead fish collector is arranged on a dead fish collector holder 8 in the internal net 7. A height-adjustable holder 8 for a dead fish collector is arranged substantially in the center of the main outlet arrangement as shown in 20 Figure 4. The dead fish collector has a weight such that it has a stable position in the dead fish collector holder in the internal net. A further view of the dead fish collector 9 is shown in Figure 5. The dead fish collector 9 comprises edges 31 in order to support the attachment of the dead fish collector 9 to the dead fish holder 8. The dead fish collector 9 has a weight adapted to stand firmly on the dead fish collector holder 8.25Figure 8 and 9 show a closed fish pen assembly 1, wherein the bottom support element is attached to the side sheet 3c and bottom sheet 3. Attaching means 32 are attached at the transition between the side sheet 3c and the bottom sheet 3. The attaching means 32 in this example is a sheet or fabric, but other known alternatives may be envisaged. Connecting 30 means 33 connect the attaching means 32 to the bottom support element 2. The connecting means 33 in the present example is a rope, but other known alternatives may be envisaged.Figure 10 and 11 show a closed fish pen assembly 1, wherein the bottom support element is attached to the side sheet 3c and bottom sheet 3 through a bottom ring 34. The bottom 35 support element 2 is connected to a bottom ring 34. The bottom sheet 3c is attached to a bottom ring by attaching means 32. The attaching means 32 in the present example is piece 35015410or sheet, but other known alternatives may be envisaged. The attaching means 32 is further attached to the bottom sheet 3. Connecting means 33 connect the attaching means 32 to the bottom ring 34.5 Figure 12 shows a closed fish pen assembly 1, with a low horizontal inclination bottom sheet and bottom support element. Figure 13 shows the attachment of the bottom support element 2 on the side support 21.Figure 14 shows an exemplary main outlet arrangement 37. A lower section 3e of the bottom 10 sheet 3 and a lower section 2e of the bottom support element 2 are attached to the main outlet arrangement 37. The main outlet arrangement 37 comprises a main water outlet pipe 22. The main outlet arrangement 37 further comprises a bottom plate 10. The main outlet arrangement 37 further comprises sludge connector 24.. The main outlet for water goes through the outlet pipe 22, which is double-secured with grates 26 and 23 to prevent the 15 escape of fish or foreign fish swimming into the cage. The bottom plate 20 may have a slope that is substantially the same as the slope of a lower section of the bottom sheet and the bottom support element, the bottom sheet and the bottom support element being attached to the bottom plate 10. The bottom plate 10 may comprise at least partly grooves or grids. The main water outlet pipe 22 in the main outlet arrangement 37 has a diameter sufficient to 20 release the desired amount of water with low pressure loss.Figures 15 and 16 show the dead fish collector 9 in engaged (lowered) and disengaged (raised) position, respectively. An upper section 36 of the dead fish collector holder engages with the edge 31 of the dead fish collector.25 To expel the water flow that is pumped into the net pen, a slightly higher pressure is required inside the net pen than in the water outside the net pen. This overpressure also ensures that the net pen is kept expanded so that the entire volume of the net pen can be utilized for aquaculture. This overpressure should not be too high to limit the energy costs of pumping the water flow in and also not create vertical and horizontal forces that overload the net pen.30 Nevertheless, the overpressure should be sufficient to drive the water flow out through the bottom unit of the net pen. This overpressure should normally only be a few centimeters of water column and preferably not exceed 10 cm in height. To achieve this, the bottom unit must have a sufficient cross-section to ensure these conditions.35 According to an embodiment, a method of assembling a floating, closed fish pen assembly is provided. The method comprises providing the bottom support element on a surface. That 35015411surface may be on land, or an off-shore surface such as on a vessel. The method comprises raising the bottom sheet above the bottom support element. The method comprises centering the bottom support element and bottom sheet. The method comprises lowering the bottom sheet onto the bottom support element. The method comprises connecting at least a 5 portion of the outer surface of the bottom sheet and at least a portion of the inner surface of the bottom support element with an attachment arrangement interposed between said bottom sheet and bottom support element. The method comprises lowering the bottom support element with the connected bottom sheet inside the floating ring.10 Having described example embodiments of the invention it will be apparent to those skilled in the art that other embodiments incorporating the concepts may be used. These and other non-limiting examples illustrated above are intended by way of example only and the actual scope of the invention is to be determined from the following claims.15
