THE KNOCK-DOWN (ASSEMBLING AND DISSASEMBLING) SYSTElVfOF

THE FLOATING FISH CAGE AND ITS METHOD OF MANUFACTURE

Field of the Invention

The present invention relates to the knock-down (assembling and disassembling) system of a particular "Floating Fish Cage" and its manufacturing method. To be more specific, this invention emphasize on the "Knock-Down System" "Floating Fish Cage" for breeding and cultivating fish on the seacoast, offshore sea, river, and lake. With this special method of assembling, the "Floating Fish Cage" can easily be assembled into variety of layouts and for later expansion. It can also be dismantled for easier transportation to a desired place.

Backround of the Invention

The Republic of Indonesia is the biggest archipelago in the world, with no less than 17,000 islands scattered from Sabang, all the way to Meraukel vast length of coastal line; superb fishery potentials; which is far from optimum utilization. Most "Floating Fish Cage" farmers in Indonesia are using used plastic barrels as floaters, wood materials as walkways and barrel joiners. Indonesian even uses woods as housing materials. The numbers of "Floating Fish Cage" farmers in Indonesia are estimated to reach 350.000 people. If each farmer only has 10 cells "Floating Fish Cage", we can imagine how much wood are being used. Not to mention that the water to cause those woods to start to be completely decay within 1 to 2 years only. Excessive wood cutting is obviously bad for our forest, especially when it's already in a critical state. And about all those used barrels, we know most of barrels were used as chemical containers. We will never know what other function has it been used for prior to being used as floaters. Even after it's been cleaned, it is still not safe to be used. The wall thickness of those chemical barrels is very thin, usually only 4mm to 6mm, even tied its easily loosen, and some will dent when struck by waves. Another group of fish farmers are using styrofoam or PVC pipes as floaters, and both definitely not environmentally friendly. In relation with the international agreement, it is not recommended to use woods and other "non-environmentally friendly" materials, as well as materials that can contaminate the farmed fish. All farmed fish using "non- environmentally friendly" "Floating Fish Cages" are not permitted to be exported.

There are efforts to deal with problems stated above. As technology improved, we previously able to manufacture pre-assemble "Fish Cage" components. These will be assembled into a permanent fish cage on site. These old fish cage technologies requires specialized tools such as welding equipment and an expert to utilize those equipments, as well as the availability of supplies of electricity to operate it. The assembling cost will rise and this method will require a lot of time to finish. Most importantly, after being welded, these "Floating Fish Cages" will not be able to be dismantled anymore and impossible to relocate. Even though the inventor describes it as "Knock-Down", they can't be called "Knock-Down" as they can't actually be dismantled without certain damage. These "Fish Cages" have to be dismantled forcefully with welding cutter. These kinds of "Fish Cages" still have a lot of flaw in terms of being "Fully Knock-Down" and still relatively expensive for fish farmers to afford.

In addition mentioned above, there are a few other kinds of "Floating Fish Cage" available in the market with "rectangular shape" or "ring shape", where the main structure of the "Floating Fish Cage" are made of commonly used PVC pipes. These "Floating Fish Cage" has weaknesses such as ■ ^' • Low buoyancy rate, which requires additional floaters attach along the main structures

• Short lifespan of main structure

• Easily damage when use in large waves or strong current areas

The main cause for all weaknesses stated above is due to very thin wall structure and/or small pipe diameter. Besides, the joint systems for these "Floating Fish Cage" are not usually well shaped and will not be able to be welded perfectly. This will often cause leak and almost impossible to repair, as those cages are already permanent. This weakness applies to

"ring shaped" "Fish Cages" because the components were connected using welding method, where the improper shape of the joint will cause the shape to be less than a "ring shape". Less than perfect welding will also affect the construction lifetime of the "Floating Fish Cage". Furthermore, the current existed components for the "Floating Fish Cage" are unable to form any irregular shape or varieties of shape; they are rigid and can only in a form of 1 shape. Those "Floating Fish Cages" can only be arranged to form of 1 pipeline. Lately, some inventors had invented "Floating Fish Cage" that uses

Polyethylene (PE) material. With these newly invented parts, it can be assembled into many different shapes and sizes (rectangular cell, multiple rectangular cells, square cell, multiple square cells, polygonal cell, multiple polygonal cell, polygonal "Ring Shape" cell, or precise "Ring Shape" cell). The Polyethylene (PE) material preferred is considered based on its resistance to Ultra Violet (UV) Rays from the sun, has a long lifespan, and high recyclability rate. Apart from those reasons, Polyethylene (PE) are the most "environmentally friendly" material from all the olefin family.

Up to date, those "Floating Fish Cages" that uses Polyethylene (PE) as their main material is not many in our nation due to these problems ^'•

1. The size of each "Floating Fish Cage" are huge, causing it to be expensive

2. High cost in transporting enormous quantity of "Floating Fish Cage"

3. Most Polyethylene (PE) "Floating Fish Cage" requires on site assembling using Polyethylene (PE) joining equipment, equipment transportation, and technician cost, which made Polyethylene (PE) "Floating Fish Cage" too expensive to obtain. Even so called "Knock-Down" still required welding as joining methods, and presence of a technician and the availability of the electricity supply. Based on above facts, inventors are called to unite to solve the main problem of Polyethylene (PE) "Floating Fish Cages". To popularize "Floating Fish Cages", it has to be completely "Knock-Down", easy and quick to assemble that ready to be use within hours. Every shipment will include step by step instruction manual, so that fish farmers can assemble the "Floating Fish Cages" themselves.

The Advantages of "Knock-Down" "Floating Fish Cages" are :

1) Transportation costs are much cheaper due to its compact component size. The "Floating Fish Cages" has been dismantled into components. These are much more compact, making it easier to deliver to the site, thus drastically reducing delivery cost.

2) No cost required in transporting equipment to the assembling site, because the "Knock-Down" assembling process only requires simple tools like spanner to tighten the nuts, therefore no more pipe joiner equipment required and no more electric generators set necessary on site. 3) No technician expenses (travel, accommodation, etc) required, automatically cut back on expenses. 4) Faster delivery time, as "Floating Fish Cages" are components as parts and always ready and available, and able to be delivered at any time. 5) Quick assembly time. It requires less than a day to assemble "Fish Cages" in 3mtr x 3mtr x 4 cell, 4mtr x 4mtr x 4 cell, 5mtr x 5mtr x 4 cell. Even with larger sizes, they are still relatively quick to assemble. 6) "Completely Knock-Down" literally means able to be dismantled after use (not just "Knock-Down" for assembling). Useful for easy storage, able to be sold as used, able to be relocated anywhere, and easily assembled from components back into "Floating Fish Cage".

In relations to problems and weakness of previous generation "Floating Fish Cages", inventors suggests new generation "Floating Fish Cage" has to be :

• "Completely Knock-Down", easily assembled on site, able to be dismantled later

• Each components has to be pre-manufactured in the factory • Assembling can be done on site by farmers without specific skills

• Includes assembling manual book

Furthermore, once assembling completed and in the future requires relocation, then it can be dismantled only with the same tool (spanner). These are the best solution for problems stated above. Most importantly, invented "Floating Fish Cages" are made of "environmentally friendly" material and contamination free Polyethylene (PE)

Through Polyethylene (PE) "Floating Fish Cages" with "Knock- Down" system, the price can be push lower, easier to be delivered nationally, even exported. Therefore, as an inventor has created "Floating Fish Cage" that are completely "Knock-Down", it will be called "Knock^¬ down Technology System (KTST . With this invention, we are proud to take part in improving fisheries and oceanic potentials in Indonesia.

Summary of the Invention

As previously stated that this invention is related to "Completely Knock-Down" "Floating Fish Cages" and manufacturing methods, more specifically, this invention is a system of "Completely Knock-Down" "Floating Fish Cages" in breeding and cultivating fish on seacoast, offshore sea, river, and lake; whereas this "Floating Fish Cage" easily assembled into varieties of construction or dismantle to be moved to desired site, expansion, and it's manufacturing method. A system of assembling / dismantling and its manufacturing method consists of :

• A number of pipes assembled into the main structure of the "Floating Fish Cage"

• A few cube joints to connect pipe ends into "Floating Fish Cage" shape • A few tracks placed on top of track stand, on top of pipe surface as walkways

• A few net hooks attached besides track stand facing inwards into a cell of the "Floating Fish Cage"

• A few fencing poles placed in the outer corner of the pipe joints, acts as rope holder for fencing

• A number of netting tied onto the net hooks around the inner side the "Floating Fish Cage" cells.

• A few strand of rope, stretch over one fencing poles to another fencing to create a holding line, acting as fences. • A few bolts and nuts to attach pipe ends to the "Cube Joint", strongly linking the structure

The traits of this "Completely Knock-Down" "Floating Fish Cages" are components manufactured separately, but able to be assembled into a "Floating Fish Cage" and able to be dismantled when needed. This dismantling procedure does not require any specialized equipment or technician from the manufacturer. In relation to this topic, it is very important to measure the strength in joining one component onto another component. A "Floating Fish Cage" placed offshore on the sea with unpredictable weather, requires a perfect joining method (has to be strong, long lasting, resistance to corrosion, environmentally friendly, etc).

Knock-down Technology System (KTS) is different, vital joints are done using 2 main materials, which are Polyethylene (PE) and stainless steel. Preferably, even the nets are HDPE nets. The PE material mentioned are Polyethylene (PE) that fulfills the standard requirement for drinking water pipe. HDPE (High Density Polyethylene) are used for all components such as net hooks, track stand (a component to join the track for walkways onto the pipe). All PE mixtures are mixtures of HDPE and a small amount of LLDPE (Linear Low Density Polyethylene). Bolts and Nuts are made of Stainless Steel, required as a method of joining between components.

Knock-down Technology System (KTS) does not require any welding on site. The part that needs welding has been done in the factory. The only things needs to be done on site are joining stainless steel bolts and nuts from pipes to cube joint, and net hooks needs to be bolted onto the track stand using stainless steel bolts and nuts.

In joining vital components, Knock-down Technology System (KTS) is relying on 2 methods : 1) Stainless Steel casted pipe's end with various diameters and various wall thicknesses, that the inventor calls SSP (Stainless Steel PE), so called SSP pipes.

2) Relying on a components the inventor describe as "Multi Purpose Cube" (KSG) to connect SSP pipe onto another SSP pipe. KSGs are designed to be strong but flexible, able to withstand corrosion in the sea, environmentally friendly (fully made of PE) and simple.

SSP and KSG took a while to design, through consulting with experts in fisheries and oceanic department. After having much inputs, changes and improvements were made. Now is the time to implement these improvements into the "Floating Fish Cages" manufacturing process, which then called KTS.

The methods of these "Floating Fish Cages" manufacturing are emphasized on the forming of joining part on each pipe ends on the main structure of the "Floating Fish Cage". This includes :

• To place the 1^st membrane towards the near end of the pipe by welding the side of the membrane onto inner wall of the pipe.

• To carve out 3 small trench in the inner wall, in front of the 1^st membrane of the pipe, near the end of the pipe. These trenches later on act to sustain the injection with the 2^nd membrane.

• 2^nd membrane is then placed after the 1^st membrane. These 2 membranes are placed in a certain way that the 3 carved trenches will be in middle between 2^nd membrane walls in the inner wall of the pipe.

• Placing a number of bolts that pass through the outer wall of the 2^nd membrane with the bolt-heads inside the 2^nd membrane and the bolt- ends outside the pipe's end, as a connector to the joint.

• Injecting melted PE materials into the gap in between the 2^nd membranes and the inner pipe where the 3 trenches were carved out before. This method is done for both ends of the pipe where the bolt heads will be covered by melted Polyethylene (PE).

The reasons for this invention are to provide a "Floating Fish Cage" that "Completely Knock-Down" (assembles and dismantles), these are : • Easy, practical, simple and fast assembling without the need of experts

• Able to withstand strong waves, even strong current

• Has enough buoyant, therefore no additional floating device required

• Using "Environmentally Friendly" materials

• Able to be assembled into different shapes, using the same components; arranged into rectangular cell, multiple rectangular cells, square cell, multiple square cells, polygonal cell, multiple polygonal cell, polygonal "Ring Shape" cell, or precise "Ring Shape" cell; based on what the user needs.

• Manufacturing method that can produce the joint that are also "Completely Knock-Down"

Detailed Description of the Invention

Detailed explanation of this invention will now be explained fully, pointing at the numbers inside the diagrams provided.

Picture IA, it describes viewpoint where a "Floating Fish Cage" that has been fully assembled, as per invention to date. From picture 1, it's clearly shown the main structure of the "Floating Fish Cages" consists of multiple rectangular shapes. All the pipes have been fully assembled, with possibilities to expand to the left and right, front and rear as needed. In this picture, the net hasn't been placed yet.

A "Knock-Down" system of a "Floating Fish Cage" and its assembling method consists of :

• A number pieces of pipes (1), arranged and assemble into the main structure of the "Floating Fish Cage" • A number of "Cube Joints" (2), used to attach a few pipe ends (1), as part of assembling into "Floating Fish Cage" structure.

• A number of tracks (3) for walkways, placed on the upper side of those pipes (1) that acts as the main structure. • A few "Net Hooks" (4), which placed on the side of the walkways facing inwards towards the cell of the "Floating Fish Cage".

• A few "Fence Poles" (5) placed on the outer corner of the "Cube Joints" (2) of the main pipe structures of the "Floating Fish Cage"

• A few "Cage Net" (7), which are hooked onto the "Net Hooks" (4) around the inner side of the cell of that "Floating Fish Cage"

• A length of rope (6) are stretch between one "Fence Poles" (5) to another "Fence Poles" (5), creating a rope fence around the "Floating Fish Cage"

• A few Bolts and Nuts (Diagram IF - 8, 9) are used to connect pipe's ends (1) of the main structure with the joiner, so those parts will stay connected strongly.

The main characteristics of a "Knock-Down" system "Floating Fish Cage" components, they are manufactured separately for later assembling on site. But they are able to dismantle as well. Still pointing at Picture IA, it is showing a "Floating Fish Cage" that consists of multiple rectangular shapes. The structure starts off with a single rectangular shape, and based on the way the "Cube Joints" (2) are designed, it allows making variation to the "Floating Fish Cage" shapes according to their needs. Therefore, this is one of the important points of this invention! that is the "Cube Joint" (2) and pipe ends (1) which allows infinity expansions in all directions. These mention that this invention allows a very wide "Floating Fish Cage".

Subsequently, on the outer side of the "Cube Joint" (2), it is equipped with a place to hook (10) the anchor or to a permanent place to keep the "Floating Fish Cage" in place and not washed away by the current.

Now, we are looking at diagram IB. Diagram IB shows a front view of a pipe's end (1), as per invention to date. This picture shows the shape of the pipe has a shape of a precise round, which can be manufactured. The pipe acts as the main structure for the "Floating Fish Cage" as well as its floaters, and a place to attach additional accessories. Picture IB shows the first step, before the pipe ends (1) been carved for trenches (1.1).

Moving onwards to diagram 1C. Diagram 1C shows a cross-section of a pipe's end (1) for a "Floating Fish Cage". This diagram shows the 3 trenches (1.1) that are carved out in the inner wall. Diagram 1C shows the first step of the manufacturing method of the pipe's end, for later on connected to the "Cube Joint" (2). These trenches (1.1) are use to sustain the finished injection of melted Polyethylene (PE) later on. When the 2^nd membrane has merge to the pipe's end (1), this will form the shape ready to be connected.

Looking at diagram ID. Diagram ID shows a cross-section of a pipe's end (1) where the next step of the manufacturing process after Diagram 1C. Diagram ID show that the 1^st membrane (1.2) already placed inside the pipe before the 3 trenches (1.1) and weld the outer side of the 1^st membrane onto the inner wall of the pipe. The motive of using the 1^st membrane is to prevent leakage, to anticipate leakage from the 2^nd membrane (just in case.

Looking at diagram ID. Diagram ID shows a cross-section of a pipe's end (1) including the 1^st membrane and the 2^nd membrane on the end most part of the pipe's structure. Diagram IE is the next process after diagram ID in the manufacturing process.

Furthermore into Diagram IE, where Diagram IE is a cross section of a pipe's end (1) that shows the 1^st and 2^nd membranes inside the pipe structure. Diagram IE is a continuation from Diagram ID in the manufacturing process of the pipe's end. The outer side of the 2^nd membrane (1.4) has a circular support shape (1.41 and 1.42) touching the pipe's inner wall. On the outer side of the 2^nd membrane, a flange (1.43) was created with pass through holes was created as a holder for the bolts and nuts (Diagram IF - 8, 9) with the purpose to lock the pipe's end with the available joints (2). After the 2^nd membrane (1.4) has been placed below the 3 carved trenches (1.1), then the outer was of the 2^nd membrane is welded around the pipe's end outer wall, so there's will be no future leaks.

The older version on this 2^nd membrane (1.4) manufacturing, that the 2^nd membrane (1.4) has no flange attached. Instead of placing the bolts on the 2^nd membrane's flange (1.43), the bolt-heads is casted permanently inside the 2^nd membrane (1.4) with the bolt-ends sticking out. This bolt- ends will then goes into the holes on the side of the joint.

Moving onwards to diagram IF. Diagram IF shows a cross-section of a pipe's end (1) showing the 1^st membrane (1.2) and 2^nd membrane (1.4) has been held into its place in the end most part of the pipe. Diagram IF is a continuation from Diagram IE, where the hollow part (1.44) will be injected with melted Polyethylene (PE) to fullest, including the 3 trenches. Afterwards, the pipes are cooled and leave to harden. The harden Polyethylene will bond the 2^nd membrane (1.4) and the pipe's inner wall (1), forming a pipe's end ready to be connected to the "Cube Joint" (2) on site. With this injection method, the pipe's end (1) will be very strong, precise, and ease the assembling. The older version on this 2^nd membrane (1.4) manufacturing, that the

2^nd membrane (1.4) has no flange with bolt holes. Instead, the bolt-heads are casted together when the hollow area (1.44) of the 2^nd membrane is casted. In this matter, the bolts (Diagram IF - 8) can no longer be taken out or replaced from the 2^nd membrane (1.4), placed firmly inside the 2^nd membrane.

Next is Diagram IG. Diagram IG shows a front view of a pipe's end (1) of a "Floating Fish Cage" structure, after injection process was done. Diagram IG show a completed pipe's end of the "Floating Fish Cage", where Diagram IG shows the bolts pass though the holes on the flange of the 2^nd membrane (1.4).

In connecting different vital components, "Completely Knock-Down" technology relies on 2 methods :

1) Stainless Steel casted pipe's end with various diameters and various wall thicknesses, that the inventor calls SSP (Stainless Steel PE), so called SSP pipes.

2) Relying on joining components that the inventor identifies as "Multi Purpose Cube" (KSG), to connect the pipes ends (SSP) together. KSG is designed to be strong, flexible, resistance to salt water corrosion, environmentally friendly (Full PE) and simple. SSP and KSG were designed for quite a while, consulting with experts in fisheries and oceanic; gathering inputs and had gone through a lot of changes, upgrades, and now is the time to implement it into manufacturing process that the inventor call as KTS.

Manufacturing methods of these "Floating Fish Cage" are emphasized on the pipe end's structure. Pipe's end manufacturing methods involves •

• 2^nd membrane is then placed after the 1^st membrane. These 2 membranes is placed in a certain way, that the 3 carved trenches will be in middle between 2^nd membrane, in the inner wall of the pipe. • Placing a number of bolts that pass through the outer wall of the 2^nd membrane with the bolt-heads inside the 2^nd membrane and the bolt- ends outside the pipe's end, as a connector to the joint.

Looking at Diagram IH. Diagram IH is a point of view of a "Cube Joint" (2), showing how it connects to each pipe ends (1) completely to make the main structure, as per invention to date. Still from Diagram IH, it shows very clearly the actual shape of the "Cube Joint" (2) and the pipe's ends shape that looks like a flange (1.43) on the outside of the 2^nd membrane. The "Cube Joint" (2) has 4 identical surfaces on the sides, identical sides for the top and bottom sides. Each side surfaces are equipped with at least six holes to place the bolts to connect the components. The center part of the "Cube Joint" (2) has been reinforcement and with 1 hole available. On each inner corner and around the hole, 4 holes are presented (See Diagram IH).

Moving on to Diagram II. Diagram II top view of the "Cube Joint" (2), showing the shape of the sides (2) on how the pipe's end can be connected, as per invention to date. Looking at Diagram II, we can clearly see that the middle part is presented with a big hole, with the 4 corners presented with a small holes and reinforcement.

Looking at Diagram IJ. Diagram IJ shows the side view of a "Cube Joint" (2), showing the type of "Cube Joint" (2) connection to pipe's end (1) from one of the sides. All 4 sides are identical, where each side is equipped with 6 holes, ready to be bolted through with the pipe's end (1).

Continuing onto Diagram IK. Diagram IK shows top view of a few variants of assembling between pipe's ends and "Cube Joints, as per invention to date. Diagram IK, shows the "Cube Joint" (2) connected on 2 adjacent sides, forming a corner for a single square "Floating Fish Cage". Part b shows the "Cube Joint" (2) connected on 2 opposite sides forming a line, to join or to extend a pipe length, expanding the "Floating Fish Cage" cell. Part c and d variants are used for multiple cells "Floating Fish Cage". Pointing at Diagram IL, Diagram IL shows the top view of assembling of pipe's end, variants with combinations of double pipe horizontally and single pipe vertically. The justifications for these are to get additional buoyant and/or additional construction strength. Additionally, Diagram IM shows the top view of "Floating Fish Cage" assembling variants. These variants shows quadruple "Cube Joints" connected together, with the intention to have double pipe's end connected both horizontally and vertically. The justification for this is to get extraordinary construction strength for the "Floating Fish Cage".

Pictures IN show a perspective of the "Cube Joint" (2). The pictures show the cleaning or maintenance process for "Floating Fish Cage", step by step on the pipe (1).

We move on to Figure 2A. Figure 2A shows top view of an assembling variation, which in this case double hexagonal shape, as per invention to date. Diagram 2A shows a hexagonal "Floating Fish Cage", where this can be achieved by using "Triangular Joint" (2.1).

To point at Diagram 2B, shows the top view of the "Triangular Joint" (2.1). In this case, the joint is an equilateral triangle! this type of joint makes Hexagonal shape possible.

Looking at Diagram 3A, this diagram shows the top view of a large polygonal "Ring Shape" "Floating Fish Cage" using double pipe method, as per invention to date. Polygonal "Ring Shape" "Floating Fish Cage" is designed to be in a large size, only made possible if a certain type of joints (3.3) is used. In this case, the trapezium type joint (3.3) is used, as shown in Diagram 3D.

Meanwhile, Diagram 3B shows a top view of a small polygonal "Ring Shape" "Floating Fish Cage" using double pipe method, as per invention to date. To create a small polygonal "Ring Shape" "Floating Fish Cage", another type of joint needs to be used.

The same as Diagram 3C, that shows the top view of a variety of a small polygonal "Ring Shape" "Floating Fish Cage". But this diagram shows single pipe method, which also affected on which joint type is used (3.2).

As for Diagram 3D, it's a top view of assembled joint with the pipe's end using double pipe method. This diagram is an enlargement of Diagram

3A, from one of the joint (3.3) and the pipe's end (1). This shows a new type of joint (3.3) that made polygonal "Ring Shape" "Floating Fish Cage" possible using double pipe method as the main structure.

As with Diagram 3E, this shows the enlarged top view of the joint (3.2) connected to the pipe's end (1), taken from Diagram 3C. The diagram shows the how to assemble single line pipe that uses a type of joint (3.2) that made polygonal "Ring Shape" "Floating Fish Cage" possible, as per invention to date. Diagram 3F shows the top view of a joint (3.1) that has been disassembled from the pipe's end. This joint is used for assembling

"Floating Fish Cage" using double pipe (1) method. This joint is the key to assemble polygonal "Ring Shape" "Floating Fish Cage", as per invention to date.

Next, we move on to Diagram 4A. Diagram 4A shows the top view of a "Floating Fish Cage", showing a variety of "Floating Fish Cage", a precise "Ring Shape" of "Floating Fish Cage" using double pipe method, as per invention to date. A precise round "Ring Shape" "Floating Fish Cage" can only be made possible if there are precise calculations of outer pipe length (Ia) compared with the inner pipe length (Ib). This calculation has to include the type of joints as well (4.1).

To achieve a perfect "Ring Shape" for the "Floating Fish Cage", can be achieve using this formula as per example below. We take fig.4a-R15 as sample for calculation! it is a rounded fish cage that is good to hold a 150 cm diameter fish net. Presuming that multipurpose joint thickness is 3 cm, plus outer pipe length 256 cm total is 259 cm. Total of 20 sections [NJ = 20], thus center diameter of outer circle is : 259cm x 20 = 1648.84 cm or 16.4884 meter.

3.1416

Let's calculate centre diameter of inner circle:

MJ thickness 3 cm + inner pipe length 241.86 cm = total 244.86 cm

244.86 cm x 20 =1558.82 cm or 15.5882 meter

3.1416

The difference in diameter between outer and inner circle is [1648.84 cm - 1558.82 cm] / 2 = 45 cm, it represents the distance of outer and inner pipe - from center-point to center-point.

The 15.5882 meter is diameter of the centre of inner pipe, should be minus half of the diameter times 2, that is [250 mm/2] x 2 = 250 mm or 25 cm, 15.5882 meter - 25 cm = 15,339 meter. This is good for a fish net of 15 meter, because net are likely to be bigger when pulled. We can see that the difference of pipe length between the outer pipe and the inner pipe and could form a circle, when all the bolds and nuts attached to the outer pipes/MPJ/ inner pipes are tightened. We don't have to force the pipe to bend but the bolts and nuts will do it for us.

Pointing at Diagram 4B, where it shows a top view of a precise "Ring Shape" "Floating Fish Cage", assembled using double pipe method (Ia, Ib), with an enlargement on one of the section with the joint (4.1), as per invention to date. Diagram 4B shows that in creating a precise "Ring Shape" "Floating Fish Cage", there will be difference in length between the outer pipe (Ia) and inner pipe (Ib). The outer pipe (Ia) and inner pipe (Ib) scaling can be seen from the table above. Still looking at Diagram 4B, it's showing a type of joint that is different from all previous type. This type of joint (4.1) is fitted with more function compare to the other joints. The joints (4.1) is designed as one with the "Net Hook", therefore, there's no need to have separate components for each function, separated from the pipe (1). The joint (4.1) can now to act synchronously.

Looking with more in depth into Diagram 4C, where it shows side views of the joint (4.1). Diagram 4C shows a type of joint to connect pipe's ends (Ia, Ib) so the shape will form into a precise "Ring Shape" "Floating Fish Cage", as per invention to date. Still looking from Diagram 4C, the thickness of the joint is much slimmer but each function can work synchronously. Fence poles now don't have to be placed separately, because by placing this type of joint in between outer pipe (Ia) and inner pipe (Ib), automatically net poles are already placed. Usually, the common shape of a joint will be "L shape", where the lower part of the joint (4.1) consists of 2 flanges (4.2) for left and right side. The out most side (4.6) of the joint are designed to be thicker from the center part (4.4). There is a hole created on the top area (4.9) to allow horizontal "Net Fence" pole to pass through, which can be tighten with bolts and nuts (4.8). A small hole (4.7) is placed on the outer top side of the hole (4.9) and one other small hole (4.5) on the lower shoulder of the joint, both functions for "Net Side Rope" to pass through. One last hole (4.3) on the bottom shoulder of the joint acts as an anchor hook.

Focusing on Diagram 5. Diagram 5 shows the top view of multiple rectangular cells, with arrowhead variant on the front end. This type of "Floating Fish Cage" used for river applications. The basic components for this "Floating Fish Cage" are the same with the other "Floating Fish Cages", except the additional arrowhead front will act as current breaker, reducing current load against the "Floating Fish Cage". Another arrowhead function will act as garbage and debris protector that can damage the "Floating Fish Cage". This arrowhead construction is the main difference of river applications with the other applications. Below the main arrowhead pipes (Ic) attached another smaller pipe (Id), welded (Ie) together with the main pipe (Ic) to increase buoyancy and reinforcing the arrowhead strength. To create the arrowhead sides, "Cube Joints" (5.1) are used with conjunction of several pipes. This "Cube Joints" is another application variant through this invention. This "Cube Joint" (5.1) application will be explain in more detailed through Diagram 6 below. Other additional equipment components in this river application, around the "Floating Fish Cage", especially on the left and right side, are equipped stainless steel hoop (5.2), attached in 2 rows in different diameters to act as protector against the net. The external areas are equipped with additional extra strong net (5.4) as protective screen alongside the fish nets.

Finally, looking at Diagram 6. Diagram 6 shows the side view of an enlarged "Cube Joint" (5.1), especially for river application "Floating Fish Cage". The side view of this "Cube Joint" (5.1) shown is the location to attach the arrowhead pipe (Ic). This Diagram 6 explains how the extra equipments are attached to the "Cube Joint" (5.1). Firstly, this shows how one arrowhead "Cube Joint" are fasten together to the next arrowhead "Cube Joint", using stainless steel wire (6.2). Each end of the stainless steel wire (6.2) is attached to the next arrowhead "Cube Joint" (5.1) by tightening the bolt (6.3) and the nut (6.4). Then, between bolt (6.2) and nuts (6.3, 6.4), a small pipe is inserted (6.5). On the middle part of the arrowhead "Cube Joint" (5.1), a stainless steel plating (6.6) will be placed. On every corner of the stainless steel plating, a hole will be provided the plating to be bolted to the arrowhead "Cube Joint". On the cross-section of the arrowhead "Cube Joint" (5.1), a HDPE shaft will be placed (6.9). The center of the shaft will be held firmly by a pipe made of stainless steel (6.1) as well, which then will be pinned (6.8) to hold the HDPE shaft in position. Both top and bottom side of the arrowhead "Cube Joint" will be tied together with HDPE rope (6.10) as a safeguard towards the "Floating Fish Cage".

Whole components of this "Floating Fish Cage" are made of Polyethylene (PE), including the net. The only exceptions of the components are the bolts and nuts, which are mare of anti rust metal (stainless steel). This "Floating Fish Cage" invention has been designed to be "environmentally friendly" and fulfill all the international standard requirements. All the details and explanation has been thoroughly explained by using pictures and diagrams as illustration and reference, not as limitations against this invention. Other variations and modifications can be made by experts in their respective fields without altering the core motive and invention perspective, after thoroughly reading and understanding, part or fully, of this invention description, illustration and pictures.
