Abstract
This ship has a hull shape with a molded breadth of 48.4 m to 49 m, a molded depth of 23 m to 25.9 m, a summer maximum full load draft of 15.2 m or more, and an overall length of 5 times or more but less than 6.5 times the molded breadth of the hull. The height of an upper structure in which a ship bridge 3 is provided above an accommodation space 4 is 15.6 m to 18.5 m. Thus, in a cargo ship 1 having the ship bridge 3 and the accommodation space 4 in the stern, sufficient forward sea surface visibility is ensured even in ballast condition at a shallow draft while load capacity is secured.
Description
本発明は、船舶に関し、より詳細には、船橋及び居住区を船尾に有する貨物船において、積載量を確保しつつ、喫水の浅いバラスト状態においても、十分な前方の海面見通しを確保することができる船舶に関する。
The present invention relates to a ship, and more specifically, in a cargo ship having a bridge and a residential area at the stern, it is possible to ensure a sufficient forward sea level view even in a ballast state where the draft is shallow while securing a load capacity. It relates to a ship that can.
従来の貨物船においては、船橋と居住区を伴う上部構造物を船尾の機関室上に配置することが一般的である。しかしながら、船橋と居住区を船尾に設けた船舶においては、甲板上に、球形タンクの上部やセルガイドによって固定されたコンテナが無くて、前方の海面見通しの確保に障害となるような物が無い場合であっても、特に喫水の浅いバラスト状態では、船舶前方の海面見通しを確保することが困難となる。
In conventional cargo ships, it is common to place superstructures with a bridge and a residential area on the stern engine room. However, in a ship with a bridge and a residential area at the stern, there is no container on the deck that is fixed by the upper part of the spherical tank or the cell guide, and there is no obstacle to securing the sea level view ahead. Even in this case, it is difficult to ensure a sea level view ahead of the ship, particularly in a shallow draft ballast.
特に、運河を通航する際は、曳航作業の安全性を確保する等の観点等から、広い前方の海面見通しを確保する必要がある。また、新パナマ運河では、航行時の見通し要件が他の航行域において一般船舶に要求される要件に比べて、特に厳しくなる。
In particular, when navigating the canal, it is necessary to ensure a wide forward sea level view from the viewpoint of ensuring the safety of towing work. In the new Panama Canal, the visibility requirements at the time of navigation will be particularly strict compared to the requirements required for general ships in other navigation areas.
この前方の海面見通しを改善する方法として、下記のような幾つかの方法が考えられるが、それぞれ問題がある。例えば、この改善方法の一つとして、船橋の高さを上げる方法があるが、船橋の位置を高くするためには船橋と居住区を含む上部構造物の高さを高くする必要あるので、建造コスト増を招くという問題と、さらには、エアドラフトが大きくなることで、橋のかかった港湾や河川における航行が制限されるという問題がある。
The following methods can be considered as methods for improving the sea level view ahead, but each has its own problems. For example, one way to improve this is to increase the height of the bridge. To raise the position of the bridge, it is necessary to increase the height of the superstructure including the bridge and the residential area. There is a problem of incurring an increase in cost, and further, there is a problem that navigation in bridged harbors and rivers is restricted due to the large air draft.
また、例えば、日本出願の特開2002-220091号公報に記載されているように、船橋、居住区及び機関室を船首部に配置する方法もある。例えば、コンテナ船ではあるが、船体の中央部より船首側に発電機を備えた発電機室を設けるとともに、この発電機室の上部に操舵室を含む居住室を設ける一方で、船体の船尾側に推進用プロペラを回転する駆動モータを設け、船首側の発電機と船尾側の駆動モータを電気的に接続したコンテナ船が提案されている。しかしながら、この場合には波浪中動揺の影響を受けて船首側居住室における居住性が悪くなるという問題がある。また、船橋、居住区及び機関室を船体中央に配置する場合には、貨物の積載量を十分に確保できない等の弊害が生じるという問題がある。
Also, as described in Japanese Patent Application Laid-Open No. 2002-220091, for example, there is a method in which a bridge, a residential area, and an engine room are arranged at the bow. For example, although it is a container ship, a generator room with a generator is provided on the bow side from the center of the hull, and a living room including a steering room is provided above the generator room, while the stern side of the hull A container ship has been proposed in which a drive motor for rotating a propeller for propulsion is provided, and a power generator on the bow side and a drive motor on the stern side are electrically connected. However, in this case, there is a problem that the habitability in the bow side living room is deteriorated due to the influence of shaking in the waves. In addition, when the bridge, the residential area, and the engine room are arranged in the center of the hull, there is a problem that an adverse effect such as an insufficient cargo loading amount occurs.
また、喫水を深める方法では、前方見通しは改善することはできるが、運河等の水深に制限がある航路を通行する際に支障を来すという問題がある。さらに、船橋高さを保ちつつ型深さを小さくする方法では、前方見通しは改善するが、貨物倉やタンク容積の確保に支障を来し、船舶の経済性が損なわれるという問題がある。
In addition, the method of deepening the draft can improve the forward view, but there is a problem that it may hinder the passage of a channel with a limited water depth such as a canal. Furthermore, the method of reducing the mold depth while maintaining the height of the bridge improves the forward view, but there is a problem in that it hinders securing the cargo hold and tank volume and impairs the economic efficiency of the ship.
なお、帆走商船ではあるが、例えば、特開2011-098666号公報に記載されているように、この前方の見通しを確保しつつ、風の流れを有効に利用するために、マストを右舷近傍および左舷近傍に、軸心を中心に旋回自在に立設した帆走商船が提案されている。しかし、この発明は帆走商船における前方見通しの改善を図ることができるが、一般的な貨物船における前方見通しの改善には寄与しない。
Although it is a sailing merchant ship, for example, as described in Japanese Patent Application Laid-Open No. 2011-098666, in order to effectively use the flow of wind while ensuring a forward view, the mast is placed near the starboard and A sailing merchant ship has been proposed in the vicinity of the port side, which is erected upright about an axis. However, the present invention can improve the forward view of a sailing merchant ship, but does not contribute to the improvement of the forward view of a general cargo ship.
本発明は、船橋及び居住区を船尾に有する貨物船において、積載量を確保しつつ、喫水の浅いバラスト状態においても、十分な前方の海面見通しを確保できる船舶を提供することにある。
The present invention is to provide a ship capable of securing a sufficient sea level line of sight in a ballast with a shallow draft while securing a load capacity in a cargo ship having a stern with a bridge and a residential area.
上記の目的を達成するため本発明の船舶は、船橋及び居住区を船尾に有する貨物船において、船体形状を、型幅を48.4m以上で49m以下とし、型深さを23m以上で25.9m以下とし、夏季最大満載喫水を15.2m以上とし、船体の全長を前記型幅の5倍以上で6.5倍未満にすると共に、前記船橋を前記居住区の上部に設けた上部構造物の高さを上甲板より上に15.6m以上で18.5m以下として構成される。
In order to achieve the above object, the ship of the present invention is a cargo ship having a bridge and a residential area at the stern. The hull has a shape width of 48.4 m to 49 m and a mold depth of 23 m to 25 m. 9m or less, maximum summer draft of 15.2m or more, the total length of the hull is more than 5 times and less than 6.5 times the mold width, and the upper bridge is provided in the upper part of the residential area The height is set to be 15.6 m or more and 18.5 m or less above the upper deck.
この構成によれば、船体の基本要目の型幅、型深さ、夏季最大満載喫水、及び、全長の関係を上記としたことにより、十分な積載量、貨物倉またはタンク容積と推進性能をバランスよく確保しつつ、新パナマ運河を通過できる船体形状にすることができる。
According to this configuration, the relationship between the basic width of the hull, the mold depth, the maximum summer draft, and the total length are as described above, so that sufficient loading capacity, cargo hold or tank volume and propulsion performance can be achieved. While maintaining a good balance, it can be made into a hull shape that can pass through the new Panama Canal.
また、船橋を居住区の上部に設けた上部構造物の高さを15.6m以上で18.5m以下とすることにより、喫水の浅いバラスト状態においても、船舶前方の海面見通しを十分に確保することができると共に、エアドラフトを抑えることができるので、バラスト状態における運河・河川、港湾等の通航性を確保することができる。
In addition, by ensuring that the height of the superstructure with the bridge located in the upper part of the residential area is 15.6 m or more and 18.5 m or less, the sea level front in front of the ship is sufficiently ensured even in a shallow draft. In addition, since air draft can be suppressed, it is possible to ensure the trafficability of canals, rivers, ports, etc. in a ballast state.
この上部構造物の高さを15.6m以上とするのは、居住区の居住性を考慮すると,居住区の一層の高さとしては、2.6mが必要であるので、各居住区の高さを2.6m以上とし、また、船橋と居住区における居室配置のためのスペース確保のためには6層分の面積が必要であることから、上部構造物の高さは(2.6m×6層=15.6m)で15.6mの高さが必要となるためである。なお、船橋および居住区は、乗員の居住快適性を確保するためエンジンケーシングおよび煙突と分離して配置することが望ましい。
The height of this superstructure is set to 15.6m or more, considering the habitability of the residential area, 2.6m is required as the height of the residential area. The height of the superstructure is (2.6m ×) because the height is 2.6m or more, and an area of 6 layers is required to secure space for room placement in the bridge and the residential area. This is because a height of 15.6 m is required for 6 layers = 15.6 m). It is desirable that the bridge and the residential area be arranged separately from the engine casing and the chimney in order to ensure the comfort of the passengers.
そして、上記の船体主要目と船橋高さの組み合わせにより、十分な積載量、貨物倉またはタンク容積と推進性能をバランスよく確保しつつ、前方の海面見通しを十分に確保することができるので、新パナマ運河などの運河を十分に航行可能な船舶となる。
The combination of the main hull and the height of the bridge above ensures a sufficient balance between the load capacity, cargo hold or tank volume and propulsion performance, while ensuring a sufficient sea level outlook ahead. It will be a ship that can sufficiently navigate canals such as the Panama Canal.
型幅を48.4m以上で49m以下とするのは、48.4mより小さいと、復原力を十分に確保することや載貨重量を確保することが難しく、49mより大きいと、運河通行に支障をきたすからである。また、型深さを23m以上で25.9m以下とするのは、23mより小さいと貨物倉やタンク容量を確保するのが難しく、25.9mより大きいと、船橋が高くなりエアドラフトの確保が難しくなるからである。また、夏季最大満載喫水を15.2m以上とするのは、15.2mより小さくすると新パナマ運河の可航最大喫水より浅くなり、同運河を航行することによる輸送効率を十分に活かすことができないからである。なお、夏季最大満載喫水の上限を定めていないが、この夏季最大満載喫水は最大でも型深さより乾舷の分だけ小さくなるので、型深さが決まるとその上限は決まることになる。
If the mold width is 48.4 m or more and 49 m or less, if it is smaller than 48.4 m, it will be difficult to secure sufficient restoring force and load weight, and if it is larger than 49 m, it will hinder canal traffic. Because it comes. Also, if the mold depth is 23m or more and 25.9m or less, it is difficult to secure cargo hold and tank capacity if it is smaller than 23m, and if it is larger than 25.9m, the bridge will be high and air draft will be secured. It will be difficult. In addition, the maximum summer draft of 15.2m or more will be shallower than the maximum navigable draft of the new Panama Canal if it is smaller than 15.2m, and the transportation efficiency by navigating the canal cannot be fully utilized. Because. Although there is no upper limit for the maximum summer draft, this maximum summer draft is smaller than the mold depth by the amount of dry mist, so the upper limit is determined when the mold depth is determined.
そして、船体の全長を船体の型幅の5倍以上で6.5倍未満にするのは、推進性能と前方の海面見通し確保の観点からであり、船体の全長を船体の型幅の5倍より小さいと載貨重量を確保するのが難しいと共に、幅広船型になり過ぎて推進性能および操縦性能の確保が難しくなり、6.5倍より大きいと前方の海面見通し確保が難しいからである。また、船橋を居住区の上部に設けた上部構造物の高さを上甲板より上に15.6m以上で18.5m以下とするのは、前方の海面見通しの確保とエアドラフトの抑制からであり、15.6mより小さいと前方の海面見通しの確保が難しくなり、18.5mより大きいと、エアドラフトが大きくなりすぎることにより、橋の下を通過するのが困難になるからである。
And, the reason why the total length of the hull is 5 times or more and less than 6.5 times the width of the hull is from the viewpoint of propulsion performance and ensuring sea level visibility, and the total length of the hull is 5 times the width of the hull. If it is smaller, it will be difficult to secure the weight of the cargo, and it will become too wide and it will be difficult to ensure propulsion performance and maneuverability. Also, the height of the upper structure with the bridge in the upper part of the residential area should be 15.6m or more and 18.5m or less above the upper deck. Yes, if it is smaller than 15.6 m, it is difficult to ensure a sea level view ahead, and if it is larger than 18.5 m, it is difficult to pass under the bridge because the air draft becomes too large.
なお、上記の船舶において、前記船橋における監視位置を、船橋甲板より1.8m高く、前面壁から0.75m後方としたときに、この監視位置と船首端の最高部を結ぶ見通し線が、当該船舶のバラスト喫水状態で水面と交差する位置が、船体最前部から船の全長の1.5倍以下となるように前記船橋甲板の高さを設定して構成されると、確実に運河航行時のバラスト状態における前方の海面見通しを確保できるようになる。
In the above ship, when the monitoring position on the bridge is 1.8 m higher than the bridge deck and 0.75 m behind the front wall, the line of sight connecting the monitoring position and the highest part of the bow end is If the height of the bridge deck is set so that the position where it crosses the water surface in the ballast draft state of the ship is less than 1.5 times the total length of the ship from the foremost part of the ship, It becomes possible to secure a sea level view ahead in the ballast state.
上記の船舶において、前記船の全長を242m以上で318m以下として構成すると、新パナマ運河が航行可能となるので、大西洋―太平洋間の油や貨物の輸送において、大幅な輸送効率の改善が可能となる。
In the above ship, if the total length of the ship is 242m or more and 318m or less, the New Panama Canal will be able to navigate, so it will be possible to greatly improve the transportation efficiency in the transportation of oil and cargo between the Atlantic Ocean and the Pacific Ocean. Become.
上記の船舶において、遠方から視認するための灯具が配置されている灯具設置用ポストを、右舷側と左舷側の二つにして前記船橋又は前記居住区の上に配置するとともに、レーダーマストを起倒式マストで構成すると、居住区以外の灯具設置用ポストやレーダーマストが要因で、エアドラフトが高くならないようにすることができる。
In the above-mentioned vessel, the lamp installation posts on which the lamps for viewing from a distance are arranged are arranged on the bridge or the residential area with two on the starboard side and the port side, and the radar mast is started. When constructed with an inverted mast, it is possible to prevent the air draft from becoming high due to a lamp installation post and a radar mast other than the residential area.
また、上記の船舶において、煙突高さをレーダーマストの頂上よりも低く構成したり、煙突高さを前記起倒式マストで構成される前記レーダーマストを倒したときの前記レーダーマストの最高高さよりも低く構成したりすると、居住区以外の煙突が要因で、エアドラフトが大きくならないようにすることができる。
Further, in the above-mentioned ship, the chimney height is configured to be lower than the top of the radar mast, or the chimney height is set to be higher than the maximum height of the radar mast when the radar mast composed of the tilting mast is defeated. If the air draft is made low, the air draft can be prevented from becoming large due to a chimney other than the residential area.
本発明の船舶によれば、船体の基本要目の型幅、型深さ、夏季最大満載喫水、及び、全長の関係を、型幅を48.4m以上で49m以下とし、型深さを23m以上で25.9m以下とし、夏季最大満載喫水を15.2m以上とし、船体の全長を船体の型幅の5倍以上で6.5倍未満にしたことにより、十分な積載量、貨物倉またはタンク容積と推進性能をバランスよく確保しつつ、新パナマ運河を通過できる船体形状にすることができる。
According to the ship of the present invention, the basic width of the hull, the mold depth, the maximum summer draft, and the total length are set such that the mold width is 48.4 m or more and 49 m or less, and the mold depth is 23 m. By making the above 25.9m or less, maximum summer draft of 15.2m or more, and making the total length of the hull more than 5 times and less than 6.5 times the hull mold width, sufficient loading capacity, cargo hold or While ensuring a good balance between tank volume and propulsion performance, the ship can be shaped to pass through the new Panama Canal.
また、船橋を居住区の上部に設けた上部構造物の高さを15.6m以上で18.5m以下とすることにより、特に見通しの確保が困難な喫水の浅いバラスト状態においても、船舶前方の海面見通しを十分に確保することができると共に、エアドラフトを抑えることができるので、バラスト状態における運河・河川、港湾等の通航性を確保することができる。
Also, by setting the height of the superstructure with the bridge at the upper part of the residential area to be 15.6 m or more and 18.5 m or less, even in shallow ballast conditions where drafts are difficult to secure, Sea level prospects can be sufficiently secured, and air draft can be suppressed, so that it is possible to secure the trafficability of canals, rivers, ports, etc. in a ballast state.
そして、上記の船体主要目と船橋高さの組み合わせにより、十分な積載量と推進性能をバランスよく確保しつつ、前方の海面見通しを十分に確保することができるので、新パナマ運河などの運河を十分に航行可能な船舶となる。
And the combination of the main hull and the bridge height described above makes it possible to secure a sufficient sea level outlook while ensuring sufficient load capacity and propulsion performance. The ship will be able to navigate sufficiently.
以下、本発明に係る実施の形態の船舶を図面を参照しながら説明する。この本発明に係る実施の形態の船舶1は、図1及び図2に示すように、船尾に機関室2を有し、機関室2の上部に船橋3及び居住区4を有している。また、この船橋3の両側にブリッジウィング5が設けられており、船橋3の後部には煙突(ファンネル)6が設けられている。
Hereinafter, a ship according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the ship 1 according to the embodiment of the present invention has an engine room 2 at the stern and a bridge 3 and a residential area 4 at the upper part of the engine room 2. Bridge wings 5 are provided on both sides of the bridge 3, and a chimney (funnel) 6 is provided at the rear of the bridge 3.
この船舶1は、上甲板7の上に、球形タンクの上部やセルガイドによって固定されたコンテナがなくて、前方の海面見通しの確保に障害となるような物が無い船舶である。
This ship 1 is a ship that has no container fixed on the upper deck 7 by the upper part of the spherical tank or the cell guide, and has no obstacles for securing the front sea level view.
この船舶1は、船体形状を、型幅Bmを48.4m以上で49m以下とし、型深さDmを23m以上で25.9m以下とし、夏季最大満載喫水dmaxを15.2m以上とし、船体の全長LOAを船体の型幅Bmの5倍以上で6.5倍未満にする。それと共に、船橋3を居住区4の上部に設けた上部構造物の高さH1を上甲板7より上に15.6m以上で18.5m以下として構成される。この上部構造物の高さH1とは、船体中央線(センターライン)CL上の居住区4の最下部(上甲板7)から船橋3の最上端までの高さである。
This ship 1 has a hull shape of a mold width Bm of 48.4 m or more and 49 m or less, a mold depth Dm of 23 m or more and 25.9 m or less, a maximum summer draft dmax of 15.2 m or more, the overall length L OA is less than 6.5 times more than 5 times the mold width Bm of the hull. At the same time, the height H1 of the upper structure provided with the bridge 3 in the upper part of the living area 4 is configured to be 15.6 m or more and 18.5 m or less above the upper deck 7. The height H1 of the superstructure is the height from the lowest part (upper deck 7) of the residential area 4 on the hull center line (center line) CL to the uppermost end of the bridge 3.
この船舶1において、船橋3における監視位置(視点位置)9を、船橋甲板3aより1.8m高く、前面壁から0.75m後方としたときに、この監視位置9と船首端の最高部10を結ぶ前方見通し線Tcが、この船舶1のバラスト喫水状態で水面Sbと交差する位置11が、船体最前部10から船の全長LOAの1.5倍以下となるように船橋甲板3aの高さHaを設定して構成する。これにより、確実に運河航行時のバラスト状態における前方の海面見通しを確保する。
In this ship 1, when the monitoring position (viewpoint position) 9 on the bridge 3 is 1.8 m higher than the bridge deck 3 a and 0.75 m behind the front wall, the monitoring position 9 and the highest part 10 at the bow end are The height of the bridge deck 3a is such that the position 11 where the connecting line of sight Tc intersects the water surface Sb in the ballast draft state of the ship 1 is not more than 1.5 times the full length LOA of the ship from the foremost part 10 of the hull. Set Ha and configure. This ensures a sea level view ahead of the ballast during canal navigation.
更に、この船舶1において、船の全長LOAは366m以下であり、これらにより新パナマ運河が航行可能となるので、大西洋―太平洋間の油や貨物の輸送において、大幅な輸送効率の改善が可能となる。
Furthermore, in this ship 1, since the total length L OA of the ship is 366 m or less and the new Panama Canal can be navigated by these, it is possible to greatly improve the transportation efficiency in the transportation of oil and cargo between the Atlantic Ocean and the Pacific Ocean. It becomes.
型幅Bmを48.4m以上で49m以下とするのは、48.4mより小さいと載貨重量を確保するのが難しく、49mより大きいと、新パナマ運河を航行できる最大寸法要件を満たさなくなり、運河通行に支障をきたすからである。
If the mold width Bm is set to 48.4 m or more and 49 m or less, it is difficult to secure the weight if it is smaller than 48.4 m, and if it is larger than 49 m, the maximum size requirement for navigating the new Panama Canal will not be met. This is because it will hinder traffic.
また、型深さDmを23m以上で25.9m以下とするのは、23mより小さいと載貨重量を確保するのが難しいためである。そして、25.9mより大きいと、船橋が高くなりエアドラフトの確保が難しくなるからである。
Also, the reason why the mold depth Dm is 23 m or more and 25.9 m or less is that if it is smaller than 23 m, it is difficult to secure the weight of the loaded coin. And if it is larger than 25.9 m, the bridge becomes high and it is difficult to secure an air draft.
また、夏季最大満載喫水を15.2m以上とするのは、15.2mより小さくすると新パナマ運河の可航最大喫水より浅くなり、同運河を航行することによる輸送効率を十分に活かすことができないからである。
In addition, the maximum summer draft of 15.2m or more will be shallower than the maximum navigable draft of the new Panama Canal if it is smaller than 15.2m, and the transportation efficiency by navigating the canal cannot be fully utilized. Because.
そして、船体の全長LOAを船体の型幅Bmの5倍以上で6.5倍未満にする。この船体の全長LOAを船体の型幅Bmの5倍以上にする理由は、幅広船型になり過ぎないようにして推進性能および操縦性能を確保できるようにするためであり、また、構造規則上で特殊な強度検討を要求されるためである。また、6.5倍未満にする理由は、船長が大きくなり過ぎると建造コストが過大になるためであり、また、前方の海面見通し確保が難しくならないようにするためである。よって、これらの推進性能と前方の海面見通し確保の観点から、船体の全長LOAは、船体の型幅Bmの5倍以上で6.5倍未満、すなわち、「5≦LOA/Bm<6.5」となる。
Then, the total length L OA of the hull is set to be 5 times or more and less than 6.5 times the hull mold width Bm. The reason why the total length L OA of the hull is made more than 5 times the hull form width Bm is to ensure that propulsion performance and maneuverability can be secured without becoming too wide hull form. This is because special strength studies are required. Moreover, the reason for making it less than 6.5 times is that if the captain becomes too large, the construction cost will become excessive, and it will be difficult to ensure a sea level view ahead. Therefore, from the viewpoints of ensuring the propulsion performance and the sea level prospects ahead, the total length L OA of the hull is at least 5 times and less than 6.5 times the hull mold width Bm, that is, “5 ≦ L OA / Bm <6. .5 ".
また、船橋3を居住区4の上部に設けた上部構造物の高さH1を上甲板7より上に15.6m以上で18.5m以下とするのは、前方の海面見通しの確保とエアドラフトの抑制からである。
Moreover, the height H1 of the upper structure provided with the bridge 3 in the upper part of the residential area 4 is set to be 15.6 m or more and 18.5 m or less above the upper deck 7 in order to ensure the front sea level view and the air draft. This is because of the suppression.
この上部構造物の高さH1を15.6m以上とするのは、居住区4の居住性を考慮すると,居住区4の一層の高さとしては、2.6mが必要であるので、各居住区4の高さを2.6m以上とし、また、船橋3と居住区4における居室配置のためのスペース確保のためには6層分の面積が必要であることから、上部構造物の高さH1は(2.6m×6層=15.6m)で15.6mの高さが必要となる。なお、船橋3および居住区4は、乗員の居住快適性を確保するためエンジンケーシング2aおよび煙突6と分離して配置することが望ましい。
The reason why the height H1 of the superstructure is set to 15.6 m or more is that, considering the habitability of the residential area 4, 2.6 m is required as the height of the residential area 4. The height of the upper structure is set to a height of 2.6 m or more, and an area of 6 layers is necessary to secure the space for room placement in the Funabashi 3 and the residential area 4. H1 is (2.6 m × 6 layers = 15.6 m) and a height of 15.6 m is required. It is desirable that the bridge 3 and the residential area 4 be arranged separately from the engine casing 2a and the chimney 6 in order to ensure the passenger comfort.
そして、上部構造物の高さH1が18.5mより大きいと、エアドラフトが大きくなりすぎて、橋の下を通過するのが困難になり、エアドラフトがベースラインより約50mまたは水面より約41mの制限高さHp1またはHp2がある港(一般的なアメリカの港)に航行できなくなるので、18.5m以下にして、これを避ける。なお、これらの上部構造物の高さH1の設定は、船橋3の上端から煙突6やレーダーマスト12等の高さHfを8mと仮定して余裕をとった場合を想定して設定している。
If the height H1 of the superstructure is greater than 18.5 m, the air draft becomes too large to pass under the bridge, and the air draft is about 50 m from the base line or about 41 m from the water surface. Because it becomes impossible to navigate to a port (general American port) with a restricted height Hp1 or Hp2, avoid this by setting it to 18.5 m or less. The height H1 of these superstructures is set on the assumption that the height Hf of the chimney 6, the radar mast 12 and the like is 8 m from the upper end of the bridge 3 and has a margin. .
また、遠方から視認するための灯具が配置されている灯具設置用ポスト13を、右舷側と左舷側の二つにして船橋3又は居住区4の上に配置するとともに、レーダーマスト12を起倒式マストで構成すると、居住区4以外の灯具設置用ポスト13やレーダーマスト12が要因で、エアドラフトが高くならないようにすることができる。
In addition, lamp installation posts 13 on which lamps for viewing from a distance are arranged are arranged on the bridge 3 or the residential area 4 in two on the starboard side and the port side, and the radar mast 12 is raised and lowered. When configured with a type mast, the air draft can be prevented from becoming high due to the lamp installation post 13 and the radar mast 12 other than the residential area 4.
また、煙突6の高さをレーダーマスト12の頂上よりも低く構成したり、煙突6の高さを起倒式マストで構成されるレーダーマスト12を倒したときのレーダーマスト12の最高高さよりも低く構成したりすると、居住区4以外の煙突が要因で、エアドラフトが高くならないようにすることができる。
Further, the height of the chimney 6 is configured to be lower than the top of the radar mast 12, or the height of the chimney 6 is set to be higher than the maximum height of the radar mast 12 when the radar mast 12 composed of a tiltable mast is defeated. If it is configured to be low, it is possible to prevent the air draft from becoming high due to a chimney other than the residential area 4.
上記の構成の船舶1によれば、船体の基本要目の型幅Bm、型深さDm、夏季最大満載喫水dmax、及び、全長LOAの関係を上記としたことにより、十分な積載量と推進性能をバランスよく確保しつつ、新パナマ運河を通過できる船体形状にすることができる。
According to the ship 1 having the above-described configuration, the relationship between the basic width of the hull, the mold width Bm, the mold depth Dm, the summer maximum full load draft dmax, and the total length L OA is as described above. It is possible to make the hull shape that can pass through the new Panama Canal while ensuring a good propulsion performance.
また、船橋3を居住区4の上部に設けた上部構造物の高さH1を15.6m以上で18.5m以下とすることにより、喫水の浅いバラスト状態においても、船舶1の前方の海面見通しを十分に確保することができると共に、エアドラフトを抑えることができるので、バラスト状態における運河・河川、港湾等の通航性を確保することができる。
Further, by setting the height H1 of the upper structure provided with the bridge 3 in the upper part of the residential area 4 to be not less than 15.6 m and not more than 18.5 m, the sea level in front of the ship 1 can be seen even in a shallow draft. Can be sufficiently secured, and air draft can be suppressed, so that it is possible to secure the trafficability of canals, rivers, ports and the like in a ballast state.
そして、本発明の実施の形態の船舶1は下記の条件を満たすことができる。つまり、全長LOAが55m以上の船舶には、不可視距離(前方の海面見通し:貨物積載状態)V1および不可視距離(前方の海面見通し:バラスト状態)V2が船の全長LOAの2倍または500m以下であることが要求されるが、この船舶1はこの要件を満たしている。この不可視距離V1は、この船舶1の夏季最大満載喫水状態で前方見通し線Tcが水面Saと交差する位置11aと船首端10との間の前後距離となり、また、不可視距離V2は、この船舶1のバラスト喫水状態で前方見通し線Tcが水面Sbと交差する位置11と船首端10との間の前後距離となる。
And the ship 1 of embodiment of this invention can satisfy | fill the following conditions. That is, for ships with a total length L OA of 55 m or more, the invisible distance (front sea level view: cargo loading state) V1 and the invisible distance (front sea level view: ballast state) V2 are twice or 500 m of the total length L OA of the ship. Although the following is required, the ship 1 satisfies this requirement. This invisible distance V1 is the front-to-back distance between the position 11a where the forward line of sight Tc intersects the water surface Sa and the bow end 10 in the maximum summer draft state of the ship 1, and the invisible distance V2 is the ship 1 This is the front-to-rear distance between the position 11 where the forward line of sight Tc intersects the water surface Sb and the bow end 10 in the ballast draft state.
また、新パナマ運河を通航するために必要な新パナマ運河規則の要件として、最大寸法要件(neo Panamax サイズ)は船舶1の船の全長LOA=366m、幅B=49m、可航最大喫水dp=15.2mと規定されている。更に、貨物積載状態において、不可視距離(前方の海面見通し)は船の全長LOAの1倍以下であること、また、バラスト状態において、不可視距離(前方の海面見通し)は船の全長LOAの1.5倍以下であることが要求される。船舶1はこの要件を満たし、貨物積載状態およびバラスト状態にて同運河を航行可能であり、また、可航最大喫水dpにて同運河を航行可能である。
In addition, as a requirement of the new Panama Canal rule necessary to travel through the New Panama Canal, the maximum dimension requirement (neo Panamax size) is the total length L OA = 366m of the ship 1, the width B = 49m, the maximum draft of navigation dp = 15.2 m. Furthermore, in the cargo loading state, the invisible distance (front sea level line of sight) is less than 1 times the total length L OA of the ship, and in the ballast state, the invisible distance (front sea level line of sight) is the total length L OA of the ship. It is required to be 1.5 times or less. The ship 1 satisfies this requirement, and can navigate the canal in a cargo-loaded state and a ballast state, and can navigate the canal at the maximum navigable draft dp.
従って、上記の船体主要目と上部構造物の高さH1の組み合わせにより、十分な積載量、貨物倉またはタンク容積と推進性能をバランスよく確保しつつ、前方の海面見通しを十分に確保することができるので、新パナマ運河などの運河を十分に航行可能な船舶となる。
Therefore, the combination of the above-mentioned main hull and the height H1 of the upper structure can ensure a sufficient load capacity, cargo hold or tank volume and propulsion performance in a well-balanced manner while ensuring a sufficient sea level prospect in front. As a result, it will be a ship that can sufficiently navigate the Canal such as the New Panama Canal.
本発明の船舶は、船橋及び居住区を船尾に有する貨物船において、積載量を確保しつつ、喫水の浅いバラスト状態においても、十分な前方の海面見通しを確保できるので、数多くの船舶に利用することができる。
The ship of the present invention can be used for a large number of ships in a cargo ship having a bridge and a residence area at the stern because it can secure a sufficient load capacity and can ensure a sufficient sea level line of sight even in a shallow draft draft. be able to.
