Description

船種変更が容易となる油槽船Oil tank ship that makes it easy to change ship types
　本発明は、短期間かつ低コストで船種変更が容易となる油槽船に関する。 The present invention relates to an oil tank ship that can easily change the ship type in a short time and at a low cost.
　商船は、コンテナ船、ばら積貨物船、鉱石運搬船、油槽船、その他の船種に大別することができる。これらの商船は、通常、船種毎に運搬する貨物が特定されており、その貨物に適した船舶構造（配置、形状、構造、艤装等）となっている。 Merchant ships can be broadly divided into container ships, bulk carriers, ore carriers, oil tankers, and other types of ships. These merchant ships usually have cargoes specified for each ship type, and have a ship structure (arrangement, shape, structure, outfitting, etc.) suitable for the cargo.
　しかし、商船の耐用年数（使用可能期間）は、長期間（例えば２０～３０年）であり、その期間の中途で船種変更が予定されることがある。 However, the service life of a merchant ship (usable period) is long (for example, 20-30 years), and the ship type may be changed during that period.
　このような船種変更に対応する手段として、特許文献１～３が既に開示されている。 Patent Documents 1 to 3 have already been disclosed as means for dealing with such ship type changes.
　特許文献１は、中古オイルタンカーの船体部分の一部と、中古貨物船の船体部分の一部とを別の船体部分を介して接続し、新たな中古改造船とする技術に関するものである。
　特許文献２は、シングルハル貨物船をダブルハル化する工法に関するものである。
　特許文献３は、特殊な貨油管の配管構造を備えた二重船殻構造の鉱石兼油槽船に関するものである。 Patent Document 1 relates to a technique for connecting a part of a hull part of a used oil tanker and a part of a hull part of a used cargo ship via another hull part to obtain a new used remodeled ship.
Patent Document 2 relates to a method for converting a single hull cargo ship into a double hull.
Patent Document 3 relates to an ore-cum-tank ship having a double hull structure provided with a special coin oil pipe piping structure.
特開昭６１－１９１４９４号公報、「中古改造船」Japanese Patent Laid-Open No. 61-191494, “Used Modified Ship” 特開２００９－１１３７３４号公報、「シングルハル貨物船のダブルハル化工法」Japanese Patent Application Laid-Open No. 2009-113734, “Double Hull Conversion Method for Single Hull Cargo Ship” 特開平８－１１９１８８号公報、「二重船殻構造の鉱石兼油槽船」JP-A-8-119188, “Ore and oil tanker with double hull structure”
　上述したように、従来の商船は、通常、船種毎に運搬する貨物が特定されており、その貨物に適した船舶構造（配置、形状、構造、艤装等）となっていた。そのため、一旦建造された特定の船種の商船（例えば、油槽船）を別の船種に変更するためには、特許文献１，２に記載のように、船体を切断するなど、船殻構造を大幅に変更する改造工事が必要であり、長期の工事期間と、新造船の数割に相当する多額の改造費用が必要であった。 As described above, conventional merchant ships usually have a cargo to be transported for each ship type, and have a ship structure (arrangement, shape, structure, outfit, etc.) suitable for the cargo. Therefore, in order to change a merchant ship of a specific ship type (for example, an oil tank ship) once constructed to another ship type, a hull structure such as cutting the hull as described in Patent Documents 1 and 2. Remodeling work that drastically changes is required, and a long construction period and a large amount of remodeling cost equivalent to a few percent of new ships were required.
　また、特許文献３のような兼用船（鉱石兼油槽船）の場合には、貨物に適した船舶構造にできないため、兼用するいずれの船種としても使いにくく、荷役及び積載効率が低下する問題点があった。 In addition, in the case of a combined ship (Ore / oil tanker) as in Patent Document 3, it cannot be used as a ship type suitable for cargo because it cannot be made into a ship structure suitable for cargo, and there is a problem that cargo handling and loading efficiency decrease. There was a point.
　本発明は、上述した問題点を解決するために創案されたものである。
　すなわち、本発明の目的は、従来の専用船と同様に原油油槽に適した船舶構造を有しており、荷役及び積載効率が高く、かつ短期間に、低コストで、容易に別の船種（例えば鉱石運搬船又はばら積貨物船）に変更することができる船種変更が容易な油槽船を提供することにある。 The present invention has been developed to solve the above-described problems.
That is, an object of the present invention is to have a ship structure suitable for a crude oil tank like a conventional dedicated ship, and has a high cargo handling and loading efficiency, and can be easily changed to another ship type in a short time at a low cost. An object of the present invention is to provide an oil tank ship that can be changed to a ship type (for example, an ore carrier ship or a bulk carrier ship) that can be easily changed.
　本発明によれば、中央部に設けられ横置隔壁で互いに仕切られ内面が平滑な複数のセンタータンクと、
　該センタータンクの両舷に縦通隔壁を介して設けられたウイングタンクと、
　前記ウイングタンク内に設けられ前記縦通隔壁及び横肋骨（トランス）を補強するストラットと、を備え、
　前記ストラットは、変更後の船種に要求される船殻強度を確保し、前記センタータンクを変更後の船種の船倉としてそのまま転用可能に設定されている、ことを特徴とする船種変更が容易となる油槽船が提供される。 According to the present invention, a plurality of center tanks provided in the central portion and partitioned from each other by horizontal partition walls and having smooth inner surfaces;
A wing tank provided on both sides of the center tank via a longitudinal partition;
A strut provided in the wing tank to reinforce the longitudinal partition wall and the lateral rib (transformer),
The strut has a hull strength required for the changed ship type, and the ship type change is characterized in that the center tank is set to be diverted as it is as a hold of the changed ship type. An easy oil tanker is provided.
　本発明の実施形態によれば、前記横置隔壁に設けられこれを補強するコルゲート材を備え、該コルゲート材は、変更後の船種に要求される船殻強度を確保し、前記センタータンクを変更後の船種の船倉としてそのまま転用可能に設定されている。 According to an embodiment of the present invention, the corrugated material is provided on the horizontal partition wall and reinforces the corrugated material, the corrugated material ensures the hull strength required for the changed ship type, and the center tank is It is set to be divertable as it is as a hold for the new ship type.
　本発明の実施形態によれば、変更後の船種に必要となる船首楼、船首形状及び船殻強度を有する。 According to the embodiment of the present invention, it has the bow, bow shape and hull strength required for the changed ship type.
　また、変更後の船種に設けられるハッチカバーと干渉しない位置に設けられた係船機、係留金物、又は舷梯を有する。 Also, it has a mooring machine, mooring hardware, or a ladder provided at a position that does not interfere with the hatch cover provided on the changed ship type.
　また、前記センタータンク以外を介して配置され、変更後の船種においてそのまま用いられる一般配管を有する。 Also, it has a general piping that is arranged through other than the center tank and can be used as it is in the changed ship type.
　また、変更後の船種に設けられるハッチカバーを、船体構造の一部として備える。 Also, a hatch cover provided on the new ship type will be provided as part of the hull structure.
　上記本発明の構成によれば、中央部に設けられた複数のセンタータンクと、その両舷に設けられたウイングタンクとを備えているので、従来の専用船と同様に原油油槽に適した船舶構造を有しており、荷役及び積載効率が高い。 According to the above configuration of the present invention, since a plurality of center tanks provided in the central portion and wing tanks provided on both sides thereof are provided, a ship suitable for a crude oil tank like a conventional dedicated ship. It has a structure and has high cargo handling and loading efficiency.
　また、ウイングタンク内に設けられセンタータンクとの隔壁（縦通隔壁）を補強するストラットを備え、ストラットは、変更後の船種に要求される船殻強度を確保し、センタータンクを変更後の船種の船倉としてそのまま転用可能に設定されているので、船種変更の際にウイングタンクへのストラットの追設が不要であり、短期間に、低コストで、容易に別の船種（例えば鉱石運搬船又はばら積貨物船）に変更することができる。
　すなわち、ストラットは船体構造全体を支えるために必要なものであり、これらがセンタータンクにあると、船種変更時にそれを取り除き、且つウイングタンクに新たに設ける必要がある。従って、最初からウイングタンクに設けることにより、ウイングタンクへのストラットの追設を避けることができる。
  In addition, a strut is provided in the wing tank to reinforce the bulkhead (longitudinal bulkhead) with the center tank. The strut ensures the hull strength required for the new ship type, and the center tank Since it is set to be divertable as it is, it is not necessary to add struts to the wing tank when changing the ship type. It can be changed to an ore carrier or a bulk carrier.
That is, the struts are necessary to support the entire hull structure. If these are in the center tank, they must be removed when the ship type is changed and newly provided in the wing tank. Accordingly, by providing the wing tank from the beginning, it is possible to avoid the addition of struts to the wing tank.

　以下、本発明の好ましい実施形態を添付図面に基づいて詳細に説明する。なお、各図において共通する部分には同一の符号を付し、重複した説明を省略する。 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, the same code | symbol is attached | subjected to the common part in each figure, and the overlapping description is abbreviate | omitted.
　図１Ａと図１Ｂは、従来の油槽船（ｏｉｌ　ｔａｎｋｅｒ）の模式図である。図１Ａは側面図、図１Ｂは断面図、１Ａは油槽、２はバラストタンク、３は機関室、４は甲板室である。
　油槽船（以下、「タンカー」と呼ぶ）は、主として原油を輸送する船であり、衝突、座礁、油槽の洗浄等を考慮して、海洋汚染を防止するために、油槽１Ａとバラストタンク２の配置と大きさがＭＡＲＰＯＬ規則で規定されている。
　タンカーの荷役は、ローディングとアンローディングとも陸側のホースと船側の配管端を結合して行われる。また、タンカーは片航が空荷のバラスト航海になるため、ＭＡＲＰＯＬ規則で要求される専用のバラストタンク２のみで通常の航海ができるようになっている。 1A and 1B are schematic views of a conventional oil tanker. 1A is a side view, FIG. 1B is a cross-sectional view, 1A is an oil tank, 2 is a ballast tank, 3 is an engine room, and 4 is a deck room.
An oil tanker ship (hereinafter referred to as a “tanker”) is a ship that mainly transports crude oil. The arrangement and size are defined by MARPOL rules.
The tanker is loaded and unloaded by connecting the land-side hose and the ship-side pipe end. In addition, since a tanker is a ballast voyage in which one side is empty, a normal voyage can be performed only with the dedicated ballast tank 2 required by the MARPOL regulations.
　図２Ａと図２Ｂは、従来の鉱石運搬船（ｏｒｅ　ｃａｒｒｉｅｒ）の模式図である。図２Ａは側面図、図２Ｂは断面図、１Ｂは船倉、２はバラストタンク、３は機関室、４は甲板室、５は船首楼、６はハッチカバーである。
　鉱石運搬船は、鉄鉱石等の鉱石を輸送する船である。鉄鉱石等の鉱石は穀類、石炭等と比較して比重が大きいので、中央部に二重底を高くした船倉１Ｂを配置し、左右舷を大きなバラストタンク２としている。
　鉱石運搬船の荷役は、陸側の設備によるのが一般的であり、大部分の本船は、荷役設備を持っていない。また、鉱石運搬船は、片航が空荷のバラスト航海になるが、バラストタンク２の容積が十分とれるので、専用タンクの張水だけで十分な喫水を確保できる。 2A and 2B are schematic views of a conventional ore carrier. 2A is a side view, FIG. 2B is a sectional view, 1B is a hold, 2 is a ballast tank, 3 is an engine room, 4 is a deck room, 5 is a bow tower, and 6 is a hatch cover.
An ore carrier is a ship that transports ores such as iron ore. Since ore such as iron ore has a greater specific gravity than cereals and coal, a hold 1B with a double bottom is arranged in the center, and the left and right dredges are made into large ballast tanks 2.
The ore carrier is usually handled by land facilities, and most of the vessels do not have cargo handling equipment. In addition, the ore carrier ship has a ballast voyage in which the one-way voyage is empty, but since the volume of the ballast tank 2 is sufficient, a sufficient draft can be ensured only by the tension water in the dedicated tank.
　図１Ａ、図１Ｂ、図２Ａ、図２Ｂから明らかなように、それぞれ専用船である従来のタンカーと鉱石運搬船とは、以下の点で大きく相違している。
（１）　タンカーには、船首楼５、ハッチ（上部甲板の開口部）、及びハッチカバー６は原則として不要である。
（２）　タンカーの油槽１Ａは、中央とその両舷に存在するが、鉱石運搬船の船倉１Ｂは、中央のみで、その両舷にはバラストタンク２が存在する。 As is apparent from FIGS. 1A, 1B, 2A, and 2B, the conventional tanker, which is a dedicated ship, and the ore carrier ship are greatly different in the following points.
(1) As a rule, the tanker does not need the bow tower 5, the hatch (the opening of the upper deck), and the hatch cover 6.
(2) An oil tank 1A for a tanker exists in the center and both sides, but a hold 1B for an ore carrier is only in the center, and ballast tanks 2 exist on both sides.
　また、その他にも、タンカーと鉱石運搬船とは、以下の点で相違している。
（３）　タンカーの中央油槽１Ａには、多数の補強材（ストラットや水平ガーダー）が存在するが、鉱石運搬船の船倉１Ｂには、鉱石の搬出に支障があるため補強材が少ない（実質的にない）。
（４）　鉱石運搬船では、乾舷（喫水から上甲板まで）の船首形状がＩＣＬＬで要求される予備浮力を必要とするが、タンカーでは不要である。 In addition, a tanker and an ore carrier differ in the following points.
(3) There are many reinforcing materials (struts and horizontal girders) in the central oil tank 1A of the tanker, but there are few reinforcing materials in the hold 1B of the ore carrier because there is a problem in carrying out the ore. Absent).
(4) In an ore carrier, the bow shape of drought (from draft to upper deck) requires the preliminary buoyancy required by ICLL, but not in tankers.
　従って、一旦建造された油槽船を、後日、別の船種（例えば鉱石運搬船又はばら積貨物船）に変更するためには、将来の改造を想定し、少ない労力と費用で改造ができるような船舶構造（配置、形状、構造、艤装等）を新造時から採用しておく必要がある。 Therefore, in order to change an oil tank ship once constructed to another ship type (for example, an ore carrier or a bulk carrier) at a later date, it is possible to make modifications with little effort and cost in the future. It is necessary to adopt a ship structure (arrangement, shape, structure, outfit, etc.) from the time of new construction.
　図３Ａと図３Ｂは、本発明による船種変更が容易となる油槽船の模式図である。図３Ａは平面図、図３Ｂは側面図、図３Ｃは断面図であり、１０は油槽、１２は船首楼、１４はハッチカバーである。
　本発明の油槽船（タンカー）は、鉱石運搬船に船種変更できるようになっており、従来のタンカーと、油槽１０、船首楼１２、ハッチカバー１４、船首形状及びその他の船体構造で相違している。また、係船機１６、係留金物１７、舷梯１８、及び配管２０の配置においても相違している。
　なお、変更後の船種は、鉱石運搬船に限定されず、例えば、ばら積貨物船であってもよい。以下、鉱石運搬船について説明する。 3A and 3B are schematic views of an oil tank ship that makes it easy to change the ship type according to the present invention. 3A is a plan view, FIG. 3B is a side view, FIG. 3C is a cross-sectional view, 10 is an oil tank, 12 is a bow tower, and 14 is a hatch cover.
The oil tank ship (tanker) of the present invention can be changed to an ore carrier ship, and is different from a conventional tanker, an oil tank 10, a bow tower 12, a hatch cover 14, a bow shape, and other hull structures. Yes. Further, the arrangement of the mooring machine 16, the mooring piece 17, the ladder 18 and the piping 20 is also different.
The changed ship type is not limited to the ore carrier, and may be a bulk carrier, for example. Hereinafter, the ore carrier will be described.
　図３Ａ、図３Ｂ、図３Ｃにおいて、本発明のタンカーは、変更後の船種（この例では、鉱石運搬船）に設けられるハッチカバー１４を、船体構造の一部として備えている。
　船種変更後の鉱石運搬船では、船倉（後述するセンタータンク１０ａ）に鉱石を搬入、搬出するために、上部甲板にハッチ開口１３が必須となる。従って、本発明のタンカーは、船種変更後のハッチ開口１３の位置を、隔壁（ｂｕｌｋｈｅａｄ）や補強部材（ストラットやガーダー）と干渉しない位置に予め設定してある。 3A, 3B, and 3C, the tanker of the present invention includes a hatch cover 14 provided in a changed ship type (in this example, an ore carrier ship) as part of the hull structure.
In the ore carrier ship after changing the ship type, the hatch opening 13 is essential on the upper deck in order to carry in or out the ore to the hold (center tank 10a described later). Therefore, in the tanker of the present invention, the position of the hatch opening 13 after changing the ship type is set in advance to a position where it does not interfere with the bulkhead or the reinforcing member (strut or girder).
　また、船種変更時に、上部甲板を改造してハッチ開口１３を設けると、その部分の船体強度が低下するため、ハッチ周辺を補強する必要がある。そのため、本発明のタンカーは、予めハッチ開口を設けても十分な構造強度を保持するような補強がしてあり、船種変更後の補強が不要になっている。
　図３Ａ、図３Ｂ、図３Ｃにおいて、ハッチカバー１４は、船種変更前は、船体構造の強度部材として機能すればよく、ハッチカバーとして開閉できなくてもよい。すなわちこのハッチカバー１４は、船種変更の際に、簡単な作業により、短期間に、低コストで、開閉可能な本来のハッチカバー１４に改造できるようになっている。 Further, when the ship type is changed, if the upper deck is remodeled and the hatch opening 13 is provided, the hull strength of the part is lowered, so that it is necessary to reinforce the periphery of the hatch. Therefore, the tanker of the present invention is reinforced so as to maintain a sufficient structural strength even if a hatch opening is provided in advance, and the reinforcement after changing the ship type is unnecessary.
3A, 3B, and 3C, the hatch cover 14 may function as a strength member of the hull structure before the ship type is changed, and may not be opened and closed as a hatch cover. That is, the hatch cover 14 can be remodeled into an original hatch cover 14 that can be opened and closed at low cost in a short time by a simple operation when changing the ship type.
　図１０Ａと図１０Ｂは、船体構造とハッチカバーとの取り合い部を示す詳細図である。図１０Ａは改造前、図１０Ｂは改造後であり、１４ａはスカート部、２５はハッチコーミング、２６はパッキン、２７はシールバーである。
　この図に示すように、ハッチカバー１４のスカート部１４ａを切断することで、容易にハッチカバーとして流用できる。 FIG. 10A and FIG. 10B are detailed views showing a joint portion between the hull structure and the hatch cover. 10A is before modification, FIG. 10B is after modification, 14a is a skirt portion, 25 is hatch combing, 26 is packing, and 27 is a seal bar.
As shown in this figure, by cutting the skirt portion 14a of the hatch cover 14, it can be easily used as a hatch cover.
　図４Ａと図４Ｂは、従来と本発明によるウイングタンクとセンタータンクとの隔壁（縦通隔壁）の構造図である。また、図５Ａと図５Ｂは、従来と本発明によるセンタータンク間の隔壁（横置隔壁）の構造図である。
　図４Ａと図５Ａは従来例、図４Ｂと図５Ｂは本発明である。 4A and 4B are structural views of a partition wall (vertical partition wall) between a wing tank and a center tank according to the related art and the present invention. 5A and 5B are structural views of a partition wall (horizontal partition wall) between the center tank according to the related art and the present invention.
4A and 5A show a conventional example, and FIGS. 4B and 5B show the present invention.
　従来と本発明のタンカーにおいて、油槽１０は、中央部に設けられたセンタータンク１０ａと、センタータンク１０ａの両舷に設けられたウイングタンク１０ｂとからなる。
　本発明のタンカーは、鉱石運搬船に船種変更できるようになっており、その際、センタータンク１０ａは、鉱石を収容する船倉として使用し、ウイングタンク１０ｂは、空所もしくはバラストタンクとして使用する。 In the conventional tanker and the tanker of the present invention, the oil tank 10 is composed of a center tank 10a provided in the center and wing tanks 10b provided on both sides of the center tank 10a.
The tanker of the present invention can be changed to an ore carrier. At that time, the center tank 10a is used as a hold for storing the ore, and the wing tank 10b is used as an empty space or a ballast tank.
　以下、本願において、船舶の長さ方向に隣接するセンタータンク１０ａの間の隔壁１１ａを「横置隔壁」と呼び、センタータンク１０ａとウイングタンク１０ｂの間の隔壁１１ｂを「縦通隔壁」と呼ぶ。 Hereinafter, in the present application, the partition wall 11a between the center tanks 10a adjacent to each other in the length direction of the ship is referred to as a “horizontal partition wall”, and the partition wall 11b between the center tank 10a and the wing tank 10b is referred to as a “longitudinal partition wall”. .
　図４Ａに示すように、従来のタンカーでは、センタータンク１０ａの内側にストラット２１を設け、縦通隔壁１１ｂ及び横肋骨（トランス）を補強している。
　これに対し、本発明のタンカーは、図４Ｂに示すように、ウイングタンク１０ｂの内側に設けられたストラット２２を有し、縦通隔壁１１ｂ及び横肋骨（トランス）を補強している。またこの場合、センタータンク１０ａの内側にストラット２１は廃止し、センタータンク１０ａの内面を平滑に保持している。 As shown in FIG. 4A, in the conventional tanker, a strut 21 is provided inside the center tank 10a to reinforce the longitudinal partition wall 11b and the lateral rib (transformer).
On the other hand, as shown in FIG. 4B, the tanker of the present invention has struts 22 provided inside the wing tank 10b, and reinforces the longitudinal partition walls 11b and the lateral ribs (transformers). Further, in this case, the strut 21 is eliminated inside the center tank 10a, and the inner surface of the center tank 10a is held smoothly.
　また、図５Ｂに示すように、本発明のタンカーは、横置隔壁１１ａに設けられたコルゲート材２４を有し、このコルゲート材２４により、センタータンク１０ａの内面を平滑に保持したままで、横置隔壁１１ａを補強している。コルゲート材２４はこの例では、台形に折り曲げた板の底辺を横置隔壁１１ａに溶接している。しかし、コルゲート材２４の断面形状は鉱石の搬出に支障がない限り、その他の形状（例えば、矩形）であってもよい。
　またこの場合、図５Ａに示す従来の水平ガーダー２３は廃止し、センタータンク１０ａの内面を平滑に保持している。 Further, as shown in FIG. 5B, the tanker of the present invention has a corrugated member 24 provided on the horizontal partition wall 11a, and the corrugated member 24 keeps the inner surface of the center tank 10a smooth while The partition wall 11a is reinforced. In this example, the corrugated member 24 is welded to the horizontal partition wall 11a at the bottom of a plate bent into a trapezoid. However, the cross-sectional shape of the corrugated material 24 may be any other shape (for example, a rectangle) as long as there is no hindrance to carrying out the ore.
In this case, the conventional horizontal girder 23 shown in FIG. 5A is abolished and the inner surface of the center tank 10a is held smoothly.
　さらに、ストラット２２とコルゲート材２４は、変更後の船種（この例では鉱石運搬船）に要求される船殻強度を確保し、センタータンク１０ａを変更後の船種の船倉（この例では鉱石を収容する船倉）としてそのまま転用可能に設定されている。 Furthermore, the strut 22 and the corrugated material 24 ensure the hull strength required for the changed ship type (in this example, an ore carrier), and the center tank 10a with the changed ship type hold (in this example, ore) It is set to be divertable as it is as a storage tank.
　上述した構成により、本発明によるセンタータンク１０ａの内面には、補強材（ストラット２１や水平ガーダー２３）が存在しないため、鉱石の搬出に支障がなく、そのままで、鉱石運搬船の船倉として用いることができる。
　従って、本発明のタンカーは、船種変更の際にセンタータンク１０ａ（船倉）の構造変更が不要であり、短期間に、低コストで、容易に別の船種（この例では鉱石運搬船）に変更することができる。 With the above-described configuration, there is no reinforcing material (strut 21 or horizontal girder 23) on the inner surface of the center tank 10a according to the present invention, so there is no hindrance to carrying out the ore and it can be used as it is as a hold for an ore carrier. it can.
Therefore, the tanker of the present invention does not require a change in the structure of the center tank 10a (boat hold) when changing the ship type, and can be easily changed to another ship type (in this example, an ore carrier) in a short period of time at low cost. Can be changed.
　図６Ａと図６Ｂは、従来と本発明による船首部と船首形状の構造図である。図６Ａは従来例、図６Ｂは本発明である。
　従来のタンカーでは、図６Ａに示すように、船首部に船首楼１２は不要であり、船体７（ｈｕｌｌ）の上部に直接、防波壁８（ｂｕｌｗａｒｋ）が設けられていた。
　これに対し、本発明のタンカーは、図６Ｂに示すように、変更後の船種に必要となる船首楼１２を船体７と防波壁８の間に予め設置している。なお、船首楼１２の設置は必須ではなく、設置を容易にできるように防波壁８を取外し可能な構造にし、船種変更の際に、船首楼１２を新規に設置してもよい。 6A and 6B are structural diagrams of a bow portion and a bow shape according to the related art and the present invention. 6A shows a conventional example, and FIG. 6B shows the present invention.
In the conventional tanker, as shown in FIG. 6A, the bow tower 12 is not necessary at the bow portion, and the wave barrier 8 (bulwark) is provided directly on the upper portion of the hull 7 (hull).
In contrast, in the tanker of the present invention, as shown in FIG. 6B, a bow tower 12 necessary for the changed ship type is installed between the hull 7 and the wave barrier 8 in advance. It is to be noted that the installation of the bow tower 12 is not indispensable, and a structure in which the wave barrier 8 can be removed so that the installation can be easily performed, and the bow tower 12 may be newly installed when the ship type is changed.
　また、図６Ｂに示すように、乾舷（喫水から上甲板まで）の船首形状が鉱石運搬船として必要となるＩＣＬＬで要求される予備浮力を可能な限り有するように、予め設定されている。
　さらに、本発明のタンカーは、変更後の船種に必要となる船殻強度を有するように、予め設定されている。 Further, as shown in FIG. 6B, the bow shape of the freeboard (from draft to upper deck) is set in advance so as to have as much reserve buoyancy as required by ICLL necessary as an ore carrier.
Furthermore, the tanker of the present invention is preset so as to have a hull strength necessary for the changed ship type.
　上述した本発明による船首部の構造、船首形状及び船体構造により、本発明のタンカーは、船種変更の際に船首部、船首形状及び船体構造の変更が不要であり、短期間に、低コストで、容易に別の船種（この例では鉱石運搬船）に変更することができる。 Due to the above-described structure of the bow, bow shape and hull structure according to the present invention, the tanker of the present invention does not require a change of the bow, bow shape and hull structure when changing the ship type, and is low cost in a short time. Thus, it can be easily changed to another ship type (in this example, an ore carrier ship).
　図７Ａと図７Ｂは、従来と本発明による係船機と係留金物の配置図である。また、図８Ａと図８Ｂは、従来と本発明による舷梯の配置図である。
　図７Ａと図８Ａは従来例、図７Ｂと図８Ｂは本発明である。 7A and 7B are layout diagrams of the mooring machine and the mooring piece according to the prior art and the present invention. 8A and 8B are layout diagrams of the conventional and the Bandai according to the present invention.
7A and 8A show a conventional example, and FIGS. 7B and 8B show the present invention.
　図７Ａ、図８Ａに示すように、従来の係船機１６、係留金物１７ａ，１７ｂ、及び舷梯１８の配置では、変更後の船種（この例では鉱石運搬船）に設けられるハッチ開口１３及びハッチカバー１４と干渉するため、船種変更の際には、その設置位置を変更する必要があった。 As shown in FIGS. 7A and 8A, in the arrangement of the conventional mooring machine 16, the moorings 17a and 17b, and the ladder 18, the hatch opening 13 and the hatch cover provided in the changed ship type (in this example, the ore carrier). Therefore, when the ship type was changed, the installation position had to be changed.
　これに対し、本発明のタンカーでは、図７Ｂ、図８Ｂに示すように、変更後の船種（この例では鉱石運搬船）に設けられるハッチ１３及びハッチカバー１４と干渉しない位置に、係船機１６、係留金物１７ａ，１７ｂ、及び舷梯１８が予め設けられている。
　なおこの構成は、必須ではなく、作業性が悪化する場合には、変更を容易にできるように、取付け場所を予め確保し、従来の位置に係船機１６、係留金物１７ａ，１７ｂ、又は舷梯１８を設置してもよい。 On the other hand, in the tanker of the present invention, as shown in FIGS. 7B and 8B, the mooring machine 16 is located at a position where it does not interfere with the hatch 13 and the hatch cover 14 provided in the changed ship type (ore carrier ship in this example). The moorings 17a and 17b and the ladder 18 are provided in advance.
This configuration is not essential, and if the workability deteriorates, a mounting location is secured in advance so that the change can be easily performed, and the mooring machine 16, the moorings 17a and 17b, or the Bandai 18 are placed at the conventional positions. May be installed.
　図９Ａと図９Ｂは、従来と本発明による配管の配置図である。図９Ａは従来例、図９Ｂは本発明である。
　タンカーの配管２０は、消火、油圧、清水、圧縮空気等の一般管２０ａと、貨油管２０ｂとに区分できる。
　従来のタンカーでは、図９Ａに示すように、一般管２０ａと貨油管２０ｂの両方を、センタータンク１０ａを介して設置していた。 9A and 9B are arrangement diagrams of piping according to the prior art and the present invention. 9A shows a conventional example, and FIG. 9B shows the present invention.
The tanker piping 20 can be divided into general pipes 20a such as fire extinguishing, hydraulic pressure, fresh water, and compressed air, and coin oil pipes 20b.
In the conventional tanker, as shown in FIG. 9A, both the general pipe 20a and the coin oil pipe 20b are installed via the center tank 10a.
　これに対し、本発明では、図９Ｂに示すように、一般管２０ａが、センタータンク以外（例えば、ウイングタンク１０ｂ内）を介して配置され、変更後の船種においてそのまま用いるようになっている。
　なお、貨油管２０ｂは、変更後の船種（この例では鉱石運搬船）では、不要となり、撤去するので、従来と同様に設置されている。 On the other hand, in this invention, as shown to FIG. 9B, the general pipe | tube 20a is arrange | positioned via other than a center tank (for example, in the wing tank 10b), and it uses it as it is in the ship type after a change. .
Note that the coin oil pipe 20b is not necessary for the changed ship type (in this example, an ore carrier ship) and is removed, so that it is installed in the same manner as in the past.
　この構成により、船種変更の際に、貨油管２０ｂを撤去するだけで、一般管２０ａはそのまま使用できるので、船種変更の際に配管の変更が不要であり、短期間に、低コストで、容易に別の船種（この例では鉱石運搬船）に変更することができる。 With this configuration, when the ship type is changed, the general pipe 20a can be used as it is simply by removing the coin oil pipe 20b, so there is no need to change the piping when changing the ship type, and the cost can be reduced in a short period of time. It can be easily changed to another ship type (in this example, an ore carrier).
　本発明のタンカーは、上述した構造のほかに、改造後の船種に必要な規則を満たすように、船体構造を設計し、改造後を考慮した船殻強度となっている。
　従って、船種変更の際に、改造後の船種に必要な規則を満たしており、新たな改造箇所はほとんどないので、短期間に、低コストで、容易に別の船種（この例では鉱石運搬船）に変更することができる。 In addition to the above-described structure, the tanker of the present invention has a hull structure that is designed to satisfy the rules required for the modified ship type and has a hull strength that takes into account the modified structure.
Therefore, when changing the ship type, the necessary rules for the new ship type are satisfied and there are few new remodeled parts. Ore carrier).
