The ballast tank chamber 49 is divided into two by a partition plate 51. ing. The ballast tank chamber 49 may be used as a void chamber. Further, a fuel oil tank chamber 53 for storing fuel oil B as a driving source of the diesel engine is formed between the pair of vertical wall plates 41 and 43 in the double vertical partition wall 39, and the fuel oil tank chamber A piping chamber 55 in which piping for fuel oil (not shown) is provided is formed below 53.

次に、本発明の実施形態の作用について説明する。   Next, the operation of the embodiment of the present invention will be described.

貨物船１は、船体外殻３と船体内殻５とを具備した船体二重殻構造を採っており、燃料油タンク室５１は、二重縦通隔壁３９における一対の縦壁板４１，４３の間に形成されるため、燃料油タンク室５３を船体外殻３から十分に離隔することができる。特に、二重縦通隔壁３９は、左舷及び右舷の船側外板７，９よりも少なくとも５ｍ以上船体中心側に位置するように構成されているため、燃料油タンク室５３を左舷及び右舷の船側外板７，９から十分に離隔することができる。   The cargo ship 1 has a hull double shell structure including a hull outer shell 3 and a hull shell 5, and the fuel oil tank chamber 51 has a pair of vertical wall plates 41, 43 in the double vertical partition wall 39. Therefore, the fuel oil tank chamber 53 can be sufficiently separated from the hull outer shell 3. In particular, the double longitudinal bulkhead 39 is configured to be located at least 5 m or more on the hull center side from the port side and starboard ship side skins 7 and 9, so that the fuel oil tank chamber 53 is located on the ship side of the port and starboard. It can be sufficiently separated from the outer plates 7 and 9.

また、甲板２９と船底内板１７との間に前後方向へ延びた二重縦通隔壁３９が接合するように設けられてるため、船体外殻３、船体内殻５、甲板２９の他に、二重縦通隔壁３９を貨物船１の構造部材（強度部材）とすることができ、左舷の船側外板７と左舷の船側内板１３との間隔、右舷の船側外板９と右舷の船側内板１５との間隔をそれぞれ短くしても、貨物船１の前後方向の揺動（以下、縦揺れという）に対して十分な船体強度を持たせることができる。   In addition, since a double longitudinal partition wall 39 extending in the front-rear direction is provided between the deck 29 and the ship bottom inner plate 17, in addition to the hull outer shell 3, the hull shell 5, and the deck 29, The double longitudinal bulkhead 39 can be used as a structural member (strength member) of the cargo ship 1, the distance between the port side shipboard 7 and the portside shipboard 13, the starboard shipboard 9 and the starboard side Even if the distance between the inner plate 15 and the inner plate 15 is shortened, sufficient hull strength can be given to the forward and backward swinging of the cargo ship 1 (hereinafter referred to as longitudinal swing).

以上の如き、本発明の実施形態によれば、燃料油タンク室５３を船体外殻３、特に、左舷及び右舷の船側外板７，９から十分に離隔することができるため、貨物船１が航海中に衝突又は座礁等することにより、船体外殻３に亀裂が生じても、燃料油タンク室５３内の燃料油Ｂが海洋に流出することを抑えることができ、地球環境の保全を図ることができる。   As described above, according to the embodiment of the present invention, the fuel oil tank chamber 53 can be sufficiently separated from the hull outer shell 3, particularly the port side and starboard ship side skins 7, 9. Even if a crack occurs in the hull outer shell 3 due to collision or grounding during the voyage, the fuel oil B in the fuel oil tank chamber 53 can be prevented from flowing out to the ocean, and the global environment can be protected. be able to.

また、左舷の船側外板７と左舷の船側内板１３との間隔、右舷の船側外板９と右舷の船側内板１５との間隔をそれぞれ短くしても、縦揺れに対して十分な船体強度を持たせることができるため、縦揺れに伴う貨物船１の変形を抑えつつ、複数の船倉３７の総容積を増やすことができる。   Further, even if the distance between the port side shipboard 7 on the port side and the ship side inner board 13 on the port side, and the distance between the starboard side board 9 on the starboard side and the shipboard inner plate 15 on the starboard side are shortened, the hull is sufficient for pitching. Since strength can be provided, the total volume of the plurality of holds 37 can be increased while suppressing deformation of the cargo ship 1 due to pitching.
