Description

SELF-CLEANING APPARATUS FOR THE PREVENTION OF MARINE GROWTH TECHNICAL FIELD
This invention relates to new inventive designs of a range of self-cleaning and durable components for marine growth combating apparatus that harnesses natural ocean forces such as tidal fluctuations, swells, waves and currents to control and combat marine growth affecting offshore structures like jetties, oil and gas facilities, offshore wind farms and the like, by preventing marine growth that occurs on submerged structures.
BACKGROUND ART Apparatus driven by ocean waves for cleaning and preventing marine growth like barnacles on offshore structures and maintaining the structures free of marine growth is available in the market. This apparatus comprises at least one ring used individually or in a series held together with linking members to form a cage. These apparatus are normally designed to be positively buoyant so they can respond to ocean energy. The surface driven device is driven by a combination between tidal fluctuation, waves and swells while the current driven apparatus is driven downward by current forces and resurfaces when there is a lack of current due to its buoyancy.
Although effective, the apparatus nevertheless has a limited operating life span due to settlement of marine organisms on the apparatus themselves. While the components that make continuous contact to the structure can keep themselves cleaned of marine growth such as rollers, other components such as connector assemblies are subject to marine growth colonization and hereinafter defined as non self-cleaning components. These have to be coated with anti-fouling coatings and once the life of anti-fouling coating is expired, marine growth starts to settle and gradually build up to the level whereby the buoyancy of the apparatus is compromised and the product will sink and no longer be operational.
One of the most common wear and tear is the premature breakage of the connectors at the pivotal connection. This is due to the rotation of the connectors as the product is driven under ocean forces over a long period. The operating life span of the apparatus is also further reduced when these structures are operating in rough sea areas such as in typhoon prone areas. The breakage of the connectors will compromise the integrity of the apparatus. DISCLOSURE THE INVENTION
Therefore an object of this invention is to design a multiple-angle fixed connector assembly that eliminates the pivotal connection and the above-mentioned wear and tear problems. As the connector assembly is a non-self cleaning component, it has to be designed to allow the free movement of self-cleaning aids while the apparatus operates. The connector shall preferably be moulded to predetermined angles to suit the required circumference of the protected structure and shall preferably be constructed from an abrasion and impact resistant plastic material, such as High Density Poly Ethylene and the like. In the case that the connector assembly connects linkage shafts or pipes in more than one planes, the connector assembly can be designed with multiple arms to connect shafts on horizontal plane and pipe on vertical plane.
It is another object of the present invention to overcome the above disadvantages of the current ocean driven apparatus by introducing a number of mechanical self-cleaning aids to the apparatus to remove the need to apply anti-fouling coating to not self- cleaning components. The first cleaning aid will be in the form of a ring that slides back and forth randomly over the connector assembly during the apparatus operation. The relative movement of the self-cleaning ring on the connector will prevent the settlement of marine growth on not only the connector body but also the sides of the two adjoining rollers as well as itself. The ring also plays a part in cleaning the structure and itself in the process. It also prevents the connector from having direct impact against the structure and subject to premature damage. The ring could also be made from rubber as opposed to high density polyethylene (HDPE) or a combination between a HDPE core and Nylon bristles or rubber sleeve, depending upon its applications, cleaning and/or prevention. One or more self-cleaning rings may need to be supplied to keep the entire connector assembly clean during the life of the apparatus.
To prevent marine growth from settling on other parts of the assembly, where the mechanical movement of the self-cleaning ring is not permitted by the geometry of the assembly, fixed self-cleaning rings will be used. It is envisaged that the fixed self- cleaning rings, which are possibly made with long Nylon bristles, are positioned in such positions that their long bristles can continuously sweep over the surface of non self- cleaning components, during the movement of the apparatus, thus keeping marine growth away from these components.

The apparatus as shown in Figures 1 and 6 and is a surface-driven apparatus, adapted to be installed around submerged structural components for preventing growth of marine fouling. The apparatus comprises at least one ring used individually or in a series held together with linking members to form a cage.
In an embodiment, the rings of apparatus 1 are connected together, in spaced-apart array, as seen in figure 6, b means of tubular linking members (5). The tubular members are disposed substantially parallel to the submerged structural member which is surrounded by the flexible collars. Each linking member (5) has, mounted for rotation on it, at least one moving self-cleaning ring (6) which can freely rotate and move in an upwardly or downwardly direction. The roller disks are preferably made of high density plastic with a layer of soft material such as rubber or the like to serve as a component that is slightly positive buoyant. The constant movement of the self-cleaning ring (6) along the linking member is to maintain each linking member free of marine growth.
In a preferred embodiment of the invention, the individual or a series of rings, are provided with a plurality of rollers (2) linked together to constitute a collar. The roller (2) of the current embodiment is preferably made of a material that is resistant to wear and abrasion. In addition to durability, the roller (2) is also preferably made of a material that has a cushioning effect to absorb impact forces such as rubber and the like, when the roller (2) is used on submerged structures which are coated with paint, wrapped with corrosion prevention tape and others. When used on submerged structures without any form of coating on the surface or tape wrap and others, the roller (2) is preferably made of material that is highly resistant to abrasion and impact such as High Density poly Ethylene, Ralloy, Teflon and the like.
•
Each roller (2) is freely rotatable about a roller shaft (3). The roller shafts (3) of the ring are linked together by a fixed connector (4). Each connector (4) is designed with a pre- determined angle to encircle pillars with a certain diameter range. The connector (4) is linked with roller shafts (3) at either ends by locking pins 7 via two countersunk holes at each end.
Two types of connectors (4) are envisaged, one connects with roller shafts (3) on horizontal plane for the single-ring apparatus in figure 1 and the other connects both roller shafts (3) on horizontal plane and linkage pipe (5) on vertical plane for the multiple-ring apparatus in figure 6. To keep the connector (4) in Figure 1 free of marine growth settlement, one or more self-cleaning rings (6) are mounted on the connector. The relative movement of the self-cleaning aid over the body of connector (4) will keep the connector (4) clean and the random contact between the sides of self-cleaning ring (6) and the end of roller (2) will also keep all surfaces free of marine growth. To keep the connector (4) in figure 6 free of marine growth, fixed self-cleaning rings (8) with long and flexible bristles will be installed and the sweeping motion of the bristles over the surface of the connector (4) will keep its surface free of marine growth settlement.
In summary, the apparatus comprising a single or multiple ring configuration which is slightly positive buoyant in nature when surrounded a submerged structure will have constant upwardly and downwardly movement along the submerged structure according to the movement of the ocean surface in the like of waves, tidal fluctuations and swells will prevent any growth of marine fouling on the submerged structure. The apparatus is suitable to be installed in areas with rough sea conditions such as in typhoon prone areas and the like.
While the above invention has been described in terms of several embodiments, those of ordinary skilled in the art will recognize that the invention is not limited to the embodiments described, but can be practiced with modification and alteration within the meaning and scope of the appended claims.
