Description

本発明は、積載車輌デッキを十数層有する自動車運搬船の姿勢制御装置に関するものである。   The present invention relates to an attitude control device for a car carrier having ten or more layers of loaded vehicle decks.

船舶の姿勢制御に関するものとしては、例えば、実開平５−６７５９５号公報に開示のものが知られている。当該実開平５−６７５９５号公報に開示のものは、考案名称「船舶の姿勢制御装置」に係り、「船尾側に大きい荷重を受けての航行時にも船体姿勢を水平に保つことができる船舶の姿勢制御装置を提供すること」を目的とし（同公報明細書段落番号０００４参照）、「船首下部に設けられるトリム調整用のバラストタンクと、そのバラストタンクに海水などを給・排水するためのバラストポンプと、そのバラストポンプをトリム角に応じて駆動させるバラスト量制御装置」の構成により（同公報明細書段落番号０００５参照）、「積荷の積載時にも船体姿勢を水平に維持することができ、船舶推進効率の低下防止、船体動揺の低減、操船性の維持」との効果を奏する（同公報明細書段落番号００１２参照）。   For example, what is disclosed in Japanese Utility Model Laid-Open No. 5-67595 is known as a ship attitude control. The one disclosed in Japanese Utility Model Laid-Open No. 5-67595 relates to the device name “ship attitude control device”, and “the ship's attitude can be kept horizontal even when sailing under a large load on the stern side. “To provide an attitude control device” (see paragraph number 0004 of the specification of the publication), “A ballast tank for trim adjustment provided at the bottom of the bow and a ballast for supplying and discharging seawater to the ballast tank With the configuration of the pump and the ballast amount control device that drives the ballast pump according to the trim angle (see paragraph number 0005 of the same publication), "the hull attitude can be kept horizontal even when the load is loaded, The effects of “decrease in ship propulsion efficiency, reduction in hull sway, and maintenance of ship maneuverability” are achieved (see paragraph number 0012 of the same publication).

これに対し、この種の作業船ではなく、自動車運搬船においては、次のような特殊な事情が存在する。すなわち、近年、世界的に自動車の需要が増し、自動車運搬船においても一度に大量の自動車輸送が要求され、５０００台（ＳＴｃａｒ）〜６０００台（ＲＴ４３Ｌ）以上の積載を求められることが常態化され、所定の条件下ではあるが、積載台数の大きい白動車運搬船が要求されるようになってきている。   On the other hand, the following special circumstances exist not in this type of work ship but in an automobile carrier ship. That is, in recent years, the demand for automobiles has increased worldwide, and it has become normal that a large number of automobiles are required to be transported at once in an automobile carrier, and a load of more than 5000 (STcar) to 6000 (RT43L) is required. Under certain conditions, a white-car carrier ship with a large number of vehicles is required.

ところが、自動車運搬船を始めとする各種の船舶は、時としては、パナマ運河等も航行しなければならず、船舶の幅は、パナマ運河の幅（３２．３ｍ）によって一定の幅以外は航行できず、船舶の幅には一定の制限がある。
このことは、積載台数を増やすために、車輌甲板を１２層から１３層へと、上へ上へと屋上階を重ねる構造が必須のものとなり、その結果、船型は、船舶の深さ方向に甲板数を増加させるのみで、船舶の幅（＝Ｂ）と船舶の深さ（＝Ｄ）との関係においては、甚だバランスの悪い、重心が高く安定性の悪い船舶が建造されざるを得ないこととなっていた。 However, various ships including car carriers sometimes have to navigate the Panama Canal, etc., and the width of the ship can only be navigated depending on the width of the Panama Canal (32.3m). There are certain restrictions on the width of the ship.
In order to increase the number of loaded vehicles, it is necessary to have a structure in which the vehicle deck is stacked from the 12th layer to the 13th layer and the top floor is stacked up. As a result, the hull form is in the depth direction of the ship. By simply increasing the number of decks, the ship's width (= B) and ship's depth (= D) have to be built with a very poor balance, high center of gravity and poor stability. It was supposed to be.

また、自動車運搬船のバランスという観点からしても、自動車運搬船においては、その運航時において、貨物である自動車を積載する際には、様々な大きさや重量の異なる自動車を貨物として積載しなければならないことによる貨物の偏りにより生じるアンバランスや、運行に必要な消費物（例えば、ＦＯ，ＦＷ）が航行において消費されることにより生じるのアンバランス、貨物の降ろし（陸揚げ）の際に出口に近い方からの積み降ろし等によって生じるアンバランス等、様々な要因による船舶のアンバランス状態が生じる結果となっている。   Also, from the viewpoint of the balance of car carriers, car carriers must be loaded with cars of various sizes and weights as cargo when they are loaded with cargo. Near the exit when unbalanced due to unbalanced cargo, unbalanced due to consumption of consumables necessary for operation (eg FO, FW), cargo unloading (landing) The result is an unbalanced state of the ship due to various factors such as unbalance caused by loading and unloading.

このようなアンバランス状態は、自動車運搬船の航行中はもちろん停泊中においてもできる限り生じないように、トリム調整、ヒール調整を行うことによってある程度は是正されてきたが、上述の積載台数の増加に伴い、単なるトリム調整・ヒール調整だけでは充分ではなく、これを補うために船底部に載貨重量の約２０％以上の固定バラストを配置するほか、載貨重量の約２０％以上のバラスト水（海水）を両舷側等に配置するバラストタンクに張水することによって、安定で復原性を備えた自動車運搬船となる船型を確保していた。   Such an unbalanced state has been corrected to some extent by adjusting trim and heel so that it does not occur as much as possible while the car carrier is sailing or while it is anchored. Therefore, simple trim adjustment and heel adjustment are not enough. To compensate for this, a fixed ballast of about 20% or more of the loaded weight is placed on the bottom of the ship, and ballast water (seawater) of about 20% or more of the loaded weight. Was secured in a ballast tank placed on both sides, etc., to secure a hull form that would be a stable and stable car carrier.

図２は、このような状況下における従来の自動車運搬船の姿勢制御の概略を示す図であり、図２（Ａ）は、従来の自動車運搬船の姿勢制御関係装置の配置概略を示す側面図、図２（Ｂ）は、同図２（Ａ）のＣ−Ｃ断面図、図２（Ｃ）は、同図２（Ａ）のＤ−Ｄ断面図である。図２において、Ｄ−Ｄ面は、車輌積載甲板の直下に沿った変則的断面線であり、また、図において、符号１００は、自動車運搬船であり、１０１は、船底部の固定バラスト、１０２は、両舷側から船底にかけて配置される舷側バラストタンクであり、１０３は、船首バラストタンク、１０４は、船尾バラストタンクであり、いずれも内部にバラスト水（海水）が適宜張水され、これらの各所に配置されたバラスト水を適宜移動させて船舶の安定性・復原性を確保せしめている。なお、符号１０５は、プロペラであり、１０６、１０６、・・・・は、燃料タンク、１０７は、船舶機関室である。   FIG. 2 is a diagram showing an outline of attitude control of a conventional car carrier in such a situation, and FIG. 2A is a side view showing an outline of the arrangement of a conventional car carrier attitude control related apparatus. 2 (B) is a cross-sectional view taken along the line CC in FIG. 2 (A), and FIG. 2 (C) is a cross-sectional view taken along the line DD in FIG. 2 (A). In FIG. 2, a DD plane is an irregular cross-sectional line along the vehicle loading deck. In the figure, reference numeral 100 denotes a car carrier, 101 denotes a fixed ballast at the bottom of the ship, and 102 denotes The ballast tanks on the side of the ship are arranged from both sides to the bottom of the ship, 103 is the bow ballast tank, 104 is the stern ballast tank, and ballast water (seawater) is appropriately filled inside. The arranged ballast water is moved appropriately to ensure the stability and stability of the ship. In addition, the code | symbol 105 is a propeller, 106,106, ... is a fuel tank, 107 is a ship engine room.

図２に示されるように、従来の自動車運搬船１００は、１２−１３層もの車輌甲板を有し、船底部に固定バラスト（ＰＢ）１０１を載貨重量の約２０％以上も敷設し、また、両舷側から船底にかけて配置される舷側バラストタンク１０２や船首バラストタンク１０３、船尾バラストタンク１０４には載貨重量の約２０％以上ものバラスト水を張水することにより、船舶の安定性を図り、また、軽荷時であってもプロペラ１０５が海面下に没水するよう喫水の確保を図るほか、適宜バラスト水を各所にバラストタンク１０２、１０３、１０４に移動することにより、上述の船舶のトリム、ヒールの姿勢調整を行っていた。具体的には、１１０００トン級の自動車運搬船においては、前記固定バラスト１０１として、２６００トン程度、また前記各所に配置されたバラストタンク１０２、１０３、１０４等に積載されるバラスト水（ＷＢ）として２８００トン程度が積み込み、船舶の幅（Ｂ）と船舶の深さ（Ｄ）との関係で、船舶の安定性を示すＢ／Ｄを０．９５以下で建造される。   As shown in FIG. 2, a conventional car carrier 100 has a vehicle deck of 12-13 layers, and a fixed ballast (PB) 101 is laid on the bottom of the ship more than about 20% of the loaded weight. The ship side ballast tank 102, the bow ballast tank 103, and the stern ballast tank 104, which are arranged from the ship side to the bottom of the ship, are filled with ballast water of about 20% or more of the weight of the cargo to improve the stability of the ship. In addition to ensuring the draft so that the propeller 105 is submerged under the sea surface even at the time of loading, the ballast water is appropriately moved to the ballast tanks 102, 103, 104, so that the above-mentioned ship trim and heel The posture was adjusted. Specifically, in a 11000-ton class car carrier ship, the fixed ballast 101 is about 2600 tons, and the ballast water (WB) 2800 loaded on the ballast tanks 102, 103, 104, etc. disposed in the various places is 2800 tons. About tons are loaded, and B / D indicating the stability of the ship is constructed with 0.95 or less in relation to the width (B) of the ship and the depth (D) of the ship.

しかしながら、船舶の安定性を示す上記Ｂ／Ｄは、０．９５以下であり、決して、十分な値ではなく、従来の自動車運搬船は、上述してきたように、船舶の深さ方向に甲板数が増し、船舶の幅＝（Ｂ）と船舶の深さ＝（Ｄ）のバランスの悪いものであった。
また、上述してきたように、船底に固定バラスト１０１を敷設しているため、船舶の軽荷重量がその分重くなり、船舶の航行に要する消費燃料だけからいうと、前記固定バラスト１０１およびバラスト水（ＢＷ）の如く、本来の貨物ではないものを輸送せざるを得ないような状況下では、エネルギーの無駄が生じている。 However, the B / D indicating the stability of the ship is 0.95 or less, which is never a sufficient value. As described above, the conventional car carrier has a deck number in the depth direction of the ship. Further, the balance between the width of the ship = (B) and the depth of the ship = (D) was poor.
Further, as described above, since the fixed ballast 101 is laid on the bottom of the ship, the light load amount of the ship becomes heavier, and the fixed ballast 101 and the ballast water can be considered only from the fuel consumed for the navigation of the ship. As in (BW), energy is wasted in situations where it is necessary to transport non-original cargo.

さらに、バラスト水の移動によって、軽荷時にプロペラが没水するよう喫水の確保および船舶のトリム、ヒールの姿勢調整を行なつているが、バラスト水を船舶に注排水するため、プランクトンなどが他の地域に移動し、海洋の生態系の変化が環境問題となり、バラスト水の注排水が制限され、バラスト水管理規準を満たしていない水生生物等が生存している大量のバラスト水を停泊時間内で処理する術がなく、課題となっている。さらに、固定バラスト１０１およびバラスト水を積載した状態で、トリム調整・ヒール調整を行うため、いわゆる、復原性を考慮した状態で姿勢制御を行なうため、必然的に満載排水量が増加し、船舶の吃水が深くなり、運航効率が悪くなっていた。
実開平５−６７５９５号公報 In addition, the movement of the ballast water ensures the draft so that the propeller is submerged at light load, and the trim of the ship and the heel position are adjusted, but plankton, etc. are used to inject and drain the ballast water into the ship. Of the marine ecosystem has become an environmental issue, the inflow and drainage of ballast water is restricted, and a large amount of aquatic organisms that do not meet the ballast water management standards are still alive. There is no way to deal with it. Furthermore, because trim adjustment and heel adjustment are performed with the fixed ballast 101 and the ballast water loaded, the posture control is performed in a state that considers so-called stability. It became deeper and operational efficiency was worsening.
