Abstract
Description
本発明は、岸壁に係留された船舶の船体の汚濁を防止するための船体の防汚設備及び船体の防汚方法に関する。 The present invention relates to a hull antifouling facility and a hull antifouling method for preventing the hull of a ship moored on a quay.
船舶が岸壁に係留されている際、船底など海中の部分には、フジツボなどの付着動物が付着する。このような付着動物が船底に付着すると、船体が受ける水からの抵抗が増大し、船舶の速度低下や燃費低下の原因となるので、定期的に清掃作業を行って、付着動物を船底から物理的に除去する必要があった。 When the ship is moored at the quay, attached animals such as barnacles adhere to the underwater parts such as the bottom of the ship. If such attached animals adhere to the bottom of the ship, the resistance from the water received by the hull increases, causing a reduction in ship speed and fuel consumption. Need to be removed.
このような清掃作業は、潜水夫の手作業が必要で、危険を伴い、さらに時間や費用もかかるものである。そのため、清掃作業の頻度を少なくすることが望まれている。そこで、従来、船体の喫水域までの全域を、毒性の化学物質を含む防汚塗料を用いて塗装することで、付着動物の船体への付着を抑制する方法が知られている（例えば、下記特許文献１及び２参照。）
しかしながら、このような毒性の防汚塗料を用いた場合でも、付着動物の付着を必ずしも防ぎきれなかった。例えば、図４に示されるように、特に船底Ａ及びビルジキールの裏面Ｂに多数の付着動物（フジツボ）が一様に付着してしまっていた。そのため、毒性の防汚塗料によって塗装された船体であっても、船体の防汚対策が十分なされているとはいい難かった。 However, even when such a toxic antifouling paint is used, it has not always been possible to prevent the attached animals from adhering. For example, as shown in FIG. 4, a large number of attached animals (barnacles) are uniformly attached particularly to the bottom A of the ship and the back B of the bilge keel. Therefore, even if the hull is painted with a toxic antifouling paint, it is difficult to say that the hull has sufficient antifouling measures.
そこで、本発明は、船体への付着動物の付着を抑制することが可能な船体の防汚設備及び船体の防汚方法を提供することを目的とする。 Therefore, an object of the present invention is to provide a hull antifouling facility and a hull antifouling method capable of suppressing adhesion of animals attached to the hull.
本発明者らは、上記課題を解決するために鋭意検討したところ、付着動物の代表であるフジツボが、幼生のときには沖で生活するが、その後成体となるために沖から岸壁にやってくるという性質を有していることに着目して、本発明を完成するに至った。 The inventors of the present invention have made extensive studies to solve the above problems, and have found that barnacles, which are representative of adherent animals, live offshore when they are larvae, but then come offshore to quay to become adults. The present invention has been completed by paying attention to the possession.
すなわち、本発明に係る船舶の防汚設備は、岸壁に係留された船舶の船体の汚濁を防止するための船体の防汚設備であって、複数の浮体及び当該複数の浮体を順次連結する連結具を有する囲繞部材によって船体を岸壁と共に取り囲み、付着動物を誘引するための誘引部材が吊り下げ具に取り付けられた吊り下げ誘引体を囲繞部材に複数吊設することで、誘引部材を船体の周囲の海中に配置することを特徴とする。 That is, the antifouling equipment for a ship according to the present invention is an antifouling equipment for a hull for preventing the hull of a ship moored on a quay, and connects a plurality of floating bodies and the plurality of floating bodies sequentially. Surrounding the hull together with the quay by the surrounding member with the equipment, and by suspending the suspension member with the suspension member attached to the suspension device to attract the attached animals, the attraction member is placed around the hull. It is characterized by being placed in the sea.
本発明に係る船舶の防汚設備では、付着動物を誘引するための誘引部材が吊り下げ具と連結された吊り下げ誘引体を囲繞部材に複数吊設している。そのため、付着動物が成体となるために沖から岸壁にやってきたとしても、その多くは船体に至る前に誘引部材に付着することとなる。その結果、船体への付着動物の付着を抑制することが可能となる。 In the antifouling equipment for a ship according to the present invention, a plurality of suspension attracting bodies, each of which has an attracting member for attracting an attached animal and connected to a suspension tool, are suspended from the surrounding member. Therefore, even if an attached animal comes to the quay from offshore to become an adult, many of them will adhere to the attracting member before reaching the hull. As a result, it is possible to suppress the attachment of the attached animal to the hull.
また、本発明に係る船舶の防汚設備は、岸壁に係留された船舶の船体の汚濁を防止するための船体の防汚設備であって、複数の浮体及び当該複数の浮体を順次連結する連結具を有する囲繞部材によって船体を岸壁と共に取り囲み、付着動物を誘引するための複数の誘引部材が吊り下げ具によって順次連結された吊り下げ誘引体を囲繞部材に複数吊設することで、誘引部材を船体の周囲の海中に配置することを特徴とする。 Further, the antifouling equipment for a ship according to the present invention is an antifouling equipment for a hull for preventing the hull of a ship moored on a quay, and connects a plurality of floating bodies and the plurality of floating bodies sequentially. By enclosing the hull together with the quay by a surrounding member having a tool and by suspending a plurality of suspension attracting members, in which a plurality of attracting members for attracting attached animals are sequentially connected by a hanging tool, on the surrounding member, the attracting member It is arranged in the sea around the hull.
本発明に係る船舶の防汚設備では、付着動物を誘引するための複数の誘引部材が吊り下げ具によって順次連結された吊り下げ誘引体を囲繞部材に複数吊設している。そのため、付着動物が成体となるために沖から岸壁にやってきたとしても、その多くは船体に至る前に誘引部材に付着することとなる。その結果、船体への付着動物の付着を抑制することが可能となる。 In the antifouling equipment for a ship according to the present invention, a plurality of suspension attracting bodies in which a plurality of attracting members for attracting attached animals are sequentially connected by a suspension tool are suspended from the surrounding member. Therefore, even if an attached animal comes to the quay from offshore to become an adult, many of them will adhere to the attracting member before reaching the hull. As a result, it is possible to suppress the attachment of the attached animal to the hull.
好ましくは、船体には、ビルジキールが設けられており、吊り下げ誘引体の複数の誘引部材のうち少なくとも一つは、ビルジキールに対応する深度から船体の船底の下１ｍに対応する深度の範囲内に位置している。付着動物の代表であるフジツボは、光を忌避する性質も有しているので、一般的に、光の当たりにくいビルジキールの裏面や船底に付着しやすいが、このようにすることで、ビルジキールの裏面や船底への付着動物の付着をより抑制することが可能となる。 Preferably, the hull is provided with a bilge keel, and at least one of the plurality of attracting members of the hanging inducer is within a range from a depth corresponding to the bilge keel to a depth corresponding to 1 m below the bottom of the hull. positioned. Barnacles, which are representative of attached animals, also have the property of avoiding light, so in general, they tend to adhere to the back and bottom of bilge keels that are difficult to be exposed to light. It is possible to further suppress the attachment of animals attached to the ship bottom.
好ましくは、船体には、付着動物が忌避する毒性を有する防汚塗料が塗布されており、誘引部材は、防汚塗料よりも低い毒性を有する。このようにすると、付着動物は、毒性の高い船体を忌避し、誘引部材に一層誘引されることとなる。そのため、船体への付着動物の付着をより抑制することが可能となる。なお、誘引部材が防汚塗料よりも低い毒性を有するとは、誘引部材が毒性を有していない場合も含まれるものとする。 Preferably, the hull is coated with an antifouling paint having toxicity that an attached animal repels, and the attracting member has a lower toxicity than the antifouling paint. If it does in this way, an adhesion animal will avoid a hull with high toxicity, and will be further attracted to an attracting member. For this reason, it is possible to further suppress the attachment of the attached animal to the hull. The attracting member having lower toxicity than the antifouling paint includes a case where the attracting member does not have toxicity.
好ましくは、囲繞部材は、オイルフェンスである。オイルフェンスを利用することで、船体の囲繞や撤去を容易に行えるようになる。 Preferably, the surrounding member is an oil fence. By using an oil fence, the hull can be easily enclosed and removed.
好ましくは、囲繞部材は、船体と０．５ｍ〜１ｍ離間している。０．５ｍ未満であると、囲繞部材に吊設された吊り下げ誘引体が船体に当たりやすくなり、船体を傷付ける虞が高まる。１ｍを超えると、付着動物が船体に付着しやすくなる。 Preferably, the surrounding member is separated from the hull by 0.5 m to 1 m. If it is less than 0.5 m, the suspension attracting body suspended from the surrounding member is likely to hit the hull, and the risk of damaging the hull increases. If it exceeds 1 m, the attached animal tends to adhere to the hull.
一方、本発明に係る船舶の防汚方法は、岸壁に係留された船舶の船体の汚濁を防止するための船体の防汚方法であって、複数の浮体及び当該複数の浮体を順次連結する連結具を有する囲繞部材によって船体を岸壁と共に取り囲む工程と、付着動物を誘引するための誘引部材が吊り下げ具に取り付けられた吊り下げ誘引体を囲繞部材に複数吊設することで、誘引部材を船体の周囲の海中に配置する工程とを備えることを特徴とする。 On the other hand, a ship antifouling method according to the present invention is a hull antifouling method for preventing fouling of a ship hull moored on a quay, and includes a plurality of floating bodies and a plurality of floating bodies connected in sequence.

本発明に係る船舶の防汚方法では、付着動物を誘引するための誘引部材が吊り下げ具と連結された吊り下げ誘引体を囲繞部材に複数吊設している。そのため、付着動物が成体となるために沖から岸壁にやってきたとしても、その多くは船体に至る前に誘引部材に付着することとなる。その結果、船体への付着動物の付着を抑制することが可能となる。 In the antifouling method for a ship according to the present invention, a plurality of suspension attractors each having an attracting member for attracting an attached animal and connected to a suspension tool are suspended from the surrounding member. Therefore, even if an attached animal comes to the quay from offshore to become an adult, many of them will adhere to the attracting member before reaching the hull. As a result, it is possible to suppress the attachment of the attached animal to the hull.
また、本発明に係る船舶の防汚方法は、岸壁に係留された船舶の船体の汚濁を防止するための船体の防汚方法であって、複数の浮体及び当該複数の浮体を順次連結する連結具を有する囲繞部材によって船体を岸壁と共に取り囲む工程と、付着動物を誘引するための複数の誘引部材が吊り下げ具によって順次連結された吊り下げ誘引体を囲繞部材に複数吊設することで、誘引部材を船体の周囲の海中に配置する工程とを備えることを特徴とする。 Further, a ship antifouling method according to the present invention is a hull antifouling method for preventing pollution of a ship hull moored on a quay, wherein a plurality of floating bodies and a plurality of floating bodies are sequentially connected.

本発明の好適な実施形態について、図面を参照して説明する。なお、説明において、同一要素又は同一機能を有する要素には同一符号を用いることとし、重複する説明は省略する。 Preferred embodiments of the present invention will be described with reference to the drawings. In the description, the same reference numerals are used for the same elements or elements having the same function, and a duplicate description is omitted.
まず、図１〜図３を参照して、本実施形態に係る防汚設備１によって汚濁が防止される船舶１０の全体構造について説明する。船舶１０は、図１に示されるように、船体１２、推進器１４、推進方向を制御する舵１６等を備えている。本実施形態において、船舶１０は岸壁Ｑに係留されている。 First, with reference to FIGS. 1-3, the whole structure of the ship 10 in which pollution is prevented with the antifouling equipment 1 which concerns on this embodiment is demonstrated. As shown in FIG. 1, the ship 10 includes a hull 12, a propulsion device 14, a rudder 16 that controls a propulsion direction, and the like. In this embodiment, the ship 10 is moored at the quay Q.
船体１２は、船底部１２ａ及び船側部１２ｂを有している。船体１２における船底部１２ａと船側部１２ｂとの間の湾曲部分には、船首近傍から船尾近傍にかけて、ビルジキール１８が設けられている。ビルジキール１８は、船体の動揺を抑制するための板状部材であり、減揺装置として機能する。 The hull 12 has a ship bottom part 12a and a ship side part 12b. A bilge keel 18 is provided in the curved portion between the ship bottom portion 12a and the ship side portion 12b in the hull 12 from the vicinity of the bow to the vicinity of the stern. The bilge keel 18 is a plate-like member for suppressing the hull motion, and functions as a vibration reducing device.
船体１２における船体１２が海中にある領域（船体１２の喫水領域）Ｒには、防汚塗料が塗布されている。この防汚塗料は、付着動物が忌避する毒性を有している（以下、領域Ｒを毒性領域Ｒという。）。毒性領域Ｒに用いることができる防汚塗料としては、例えばアクリル樹脂系防汚塗料等がある。 Antifouling paint is applied to a region R of the hull 12 where the hull 12 is in the sea (draft region of the hull 12) R. This antifouling paint has toxicity that an attached animal avoids (hereinafter, the region R is referred to as a toxicity region R). Examples of the antifouling paint that can be used in the toxic region R include an acrylic resin antifouling paint.
続いて、図１〜図３を参照して、防汚設備１について説明する。防汚設備１は、囲繞部材２０と、複数の吊り下げ誘引体２２とを備える。 Subsequently, the antifouling equipment 1 will be described with reference to FIGS. The antifouling equipment 1 includes a surrounding member 20 and a plurality of hanging inducers 22.
囲繞部材２０は、複数の浮体２４と、連結具２６とを有している。複数の浮体２４は、一列となるように、連結具２６によって順次連結されている。なお、浮体２４としては、例えば、発泡スチロール等の発泡材料や、空気等の気体が封入された袋体を用いることができる。また、連結具２６は、浮体２４同士を連結できればよく、特に材質等を限定されない。 The surrounding member 20 includes a plurality of floating bodies 24 and a connector 26. The plurality of floating bodies 24 are sequentially connected by a connector 26 so as to form a line. As the floating body 24, for example, a foam material such as foamed polystyrene or a bag body in which a gas such as air is enclosed can be used. Moreover, the connection tool 26 should just be able to connect the floating bodies 24, and a material etc. are not specifically limited.
囲繞部材２０は、特に図２に示されるように、岸壁Ｑに係留された船舶１０の船体１２を、岸壁Ｑと共に取り囲んでいる。囲繞部材２０は、船体１２と０．５ｍ〜１ｍ離間している（囲繞部材２０と船体１２との直線距離Ｗ（図２及び図３参照）が０．５ｍ〜１ｍである）と好ましい。０．５ｍ未満であると、囲繞部材２０に吊設された吊り下げ誘引体２２（後述する）が船体１２に当たりやすくなり、船体１２を傷付ける虞が高まる。１ｍを超えると、付着動物が船体１２に付着しやすくなる。 As shown particularly in FIG. 2, the surrounding member 20 surrounds the hull 12 of the ship 10 moored to the quay Q together with the quay Q. The surrounding member 20 is preferably separated from the hull 12 by 0.5 m to 1 m (the linear distance W (see FIGS. 2 and 3) between the surrounding member 20 and the hull 12 is 0.5 m to 1 m). If the distance is less than 0.5 m, the suspension attracting body 22 (described later) suspended from the surrounding member 20 is likely to hit the hull 12 and the risk of damaging the hull 12 increases. If it exceeds 1 m, the attached animal tends to adhere to the hull 12.
この囲繞部材２０には、吊り下げ誘引体２２が所定間隔で吊設されている。具体的には、図２に示されるように、浮体２４、隣り合う浮体２４の間に位置する連結具２６、及び、岸壁Ｑに最も近い浮体２４と岸壁Ｑとの間に位置する連結具２６に、吊り下げ誘引体２２がそれぞれ吊設されている。 A suspension attracting body 22 is suspended from the surrounding member 20 at a predetermined interval. Specifically, as shown in FIG. 2, the floating body 24, the coupling tool 26 positioned between the adjacent floating bodies 24, and the coupling tool 26 positioned between the floating body 24 closest to the quay Q and the quay Q The suspension attracting bodies 22 are respectively suspended.
吊り下げ誘引体２２は、特に図１及び図３に示されるように、複数の板状部材（誘引部材）２８と、吊り下げ具３０と、重り３２とを有している。 As shown in FIG. 1 and FIG. 3 in particular, the suspension attracting body 22 has a plurality of plate-like members (attraction members) 28, a suspension tool 30, and a weight 32.
板状部材２８は、例えば鋼材や硬質プラスチックによって構成することができる。板状部材２８の大きさは、例えば０．３ｍ×０．６ｍ程度とすることができる。 The plate-like member 28 can be made of, for example, steel or hard plastic. The size of the plate-like member 28 can be set to about 0.3 m × 0.6 m, for example.
板状部材２８の表面には、船体１２の毒性領域Ｒよりも低い毒性を有する防汚塗料が塗布されている。板状部材２８の表面に用いることができる防汚塗料としては、例えばエポキシ樹脂系防蝕塗料等がある。そのため、フジツボ等の付着動物は、船体１２の毒性領域Ｒよりも板状部材２８に誘引されやすくなっている。なお、板状部材２８の表面には、防汚塗料が塗布されていなくてもよい。 An antifouling paint having toxicity lower than that of the toxic region R of the hull 12 is applied to the surface of the plate member 28. Examples of the antifouling paint that can be used on the surface of the plate-like member 28 include an epoxy resin-based anticorrosive paint. Therefore, attached animals such as barnacles are more easily attracted to the plate-like member 28 than the toxic region R of the hull 12. In addition, the antifouling paint may not be applied to the surface of the plate-like member 28.
ここで、一の吊り下げ誘引体２２が有する複数の板状部材２８のうち少なくとも一つは、ビルジキール１８に対応する深度から船底部１２ａの下１ｍに対応する深度の範囲Ｄ（図３参照）内に位置している。そのため、各吊り下げ誘引体２２の板状部材２８は、船体１２の周囲、特に、船底部１２ａ及びビルジキール１８の周囲の海中に配置されることとなる。 Here, at least one of the plurality of plate-like members 28 included in one suspension attracting body 22 has a depth range D corresponding to 1 m below the ship bottom 12a from the depth corresponding to the bilge keel 18 (see FIG. 3). Located in. Therefore, the plate-like member 28 of each suspension attracting body 22 is disposed around the hull 12, particularly in the sea around the ship bottom 12 a and the bilge keel 18.
複数の板状部材２８及び重り３２は、一列となるように、吊り下げ具３０によって順次連結されている。吊り下げ具３０は、板状部材２８及び重り３２を連結できればよく、特に材質等を限定されない。重り３２は、鋼製の球体であり、吊り下げ具３０の下端に接続されている。 The plurality of plate-like members 28 and the weights 32 are sequentially connected by a suspending tool 30 so as to form a line. The hanging tool 30 only needs to be able to connect the plate-like member 28 and the weight 32, and the material or the like is not particularly limited. The weight 32 is a steel sphere, and is connected to the lower end of the hanging tool 30.
以上のような本実施形態に係る防汚設備１において、岸壁Ｑに係留された船舶１０の船体１２の汚濁を防止するためには、まず、複数の吊り下げ誘引体２２が吊設された囲繞部材２０を用意する。続いて、この囲繞部材２０によって、船体１２を岸壁Ｑと共に取り囲む。これにより、板状部材２８が船体１２の周囲の海中に配置されることとなる。 In the antifouling equipment 1 according to the present embodiment as described above, in order to prevent the hull 12 of the ship 10 moored at the quay Q from being polluted, first, a go in which a plurality of hanging inducers 22 are suspended. A member 20 is prepared. Subsequently, the hull 12 is surrounded together with the quay Q by the surrounding member 20. As a result, the plate-like member 28 is disposed in the sea around the hull 12.
以上のような本実施形態においては、付着動物を誘引するための複数の板状部材２８が吊り下げ具２８によって順次連結された吊り下げ誘引体２２を囲繞部材２０に複数吊設している。そのため、付着動物が成体となるために沖から岸壁にやってきたとしても、その多くは船体１２に至る前に板状部材２８に付着することとなる。その結果、船体１２への付着動物の付着を抑制することが可能となる。 In the present embodiment as described above, a plurality of suspension attracting bodies 22 in which a plurality of plate-like members 28 for attracting an attached animal are sequentially connected by a suspension tool 28 are suspended from the surrounding member 20. Therefore, even if the attached animal comes to the quay from the offshore to become an adult, many of them adhere to the plate-like member 28 before reaching the hull 12. As a result, it is possible to suppress the attachment of the attached animal to the hull 12.
また、本実施形態においては、一の吊り下げ誘引体２２が有する複数の板状部材２８のうち少なくとも一つが、ビルジキール１８に対応する深度から船底部１２ａの下１ｍに対応する深度の範囲Ｄ（図３参照）内に位置している。付着動物の代表であるフジツボは、光を忌避する性質も有しているので、光の当たりにくいビルジキール１８の裏面（ビルジキール１８の海底Ｔに向かう側）や船底部１２ａに付着しやすいが、これにより、ビルジキール１８の裏面や船底部１２ａへの付着動物の付着をより抑制することが可能となっている。 In the present embodiment, at least one of the plurality of plate-like members 28 included in one suspension attracting body 22 has a depth range D (from the depth corresponding to the bilge keel 18 to the bottom 1 m of the ship bottom 12a. (See FIG. 3). Barnacles, which are representative of attached animals, also have the property of avoiding light, so they tend to adhere to the back of the bilge keel 18 that is difficult to receive light (the side of the bilge keel 18 toward the sea bottom T) and the bottom 12a. Thus, it is possible to further suppress the attachment of the attached animal to the back surface of the bilge keel 18 or the ship bottom 12a.
また、本実施形態においては、船体１２が、付着動物が忌避する毒性を有する防汚塗料が塗布された毒性領域Ｒを有しており、板状部材２８の表面に、船体１２の毒性領域Ｒよりも低い毒性を有する防汚塗料が塗布されている。そのため、付着動物は、毒性の高い船体を忌避し、板状部材２８に一層誘引されることとなる。その結果、船体１２への付着動物の付着をより抑制することが可能となる。 Further, in this embodiment, the hull 12 has a toxic region R in which an antifouling paint having toxicity that an attached animal repels is applied, and the toxic region R of the hull 12 is formed on the surface of the plate member 28. An antifouling paint having lower toxicity is applied. Therefore, the adherent animal avoids a highly toxic hull and is further attracted to the plate-like member 28. As a result, it is possible to further suppress the attachment of the attached animal to the hull 12.
以上、本発明の好適な実施形態について詳細に説明したが、本発明は上記した実施形態に限定されるものではない。例えば、囲繞部材２０としてオイルフェンスを利用するようにしてもよい。オイルフェンスを利用することで、船体１２の囲繞や囲繞部材２０の撤去を容易に行えるようになる。 Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments. For example, an oil fence may be used as the surrounding member 20. By using the oil fence, it is possible to easily remove the go of the hull 12 and the go member 20.
また、本実施形態では吊り下げ誘引体２２が複数の板状部材２８を有していたが、吊り下げ誘引体２２が有する板状部材２８は１枚であってもよい。 In the present embodiment, the suspension attracting body 22 has a plurality of plate-like members 28. However, the suspension attracting body 22 may have only one plate-like member 28.
また、本実施形態では板状部材２８に付着動物を誘引するようにしたが、付着動物を誘引できるものであれば板状に限られず種々の形状とすることができる。 Further, in the present embodiment, the adhering animal is attracted to the plate-like member 28. However, as long as the adhering animal can be attracted, the shape is not limited to the plate shape, and various shapes can be used.
