摘要本船为钢质全焊接结构、单甲板、方尾、前倾首柱带球首、单机单桨、单舵、短艏楼和艉楼、柴油机直接驱动的尾机型近海航区货船，全船设有三个货舱，并配有经ZC认可的钢质钢质液压折叠式舱口盖。本船设有艏楼，尾部主甲板上设五层甲板室。全船采用的是混合骨架形式。本船的货舱区域不设有支柱，并且采用抗扭箱，支持舱口端横梁的结构形式。船体主要构件按照中国船级社《国内航行海船建造规范》（2006）对近海航区要求进行设计。本船的肋骨间距船尾至10#和176#至船首为600mm，其它的为700mm，船底的纵骨间距为665mm。全船按总布置要求，设置左右舷贯通的水油密横舱壁七道，横舱壁均使用垂直扶强材扶强，此外，根据布置的需求设置局部纵、横舱壁数道。全船材料采用满足CCS（2001年）规范要求的船用钢，艏、艉柱采用钢板焊接。船体结构焊接要求按“船体结构焊接规格表”进行，船厂应编制合理的焊接工艺，以尽量减少焊接引起的变形，焊接船体结构的焊接材料应符合CCS《材料与焊接规范》（2001年）要求。建造厂可根据其实际情况（船厂施工场地、起重能力、施工工艺等）对船体结构进行划分，船厂应根据本船的结构特点预先制定合理的施工工艺。船上所有液体舱柜内，在其上下构件上均应开有流水（油）孔、透气孔。81329

该设计主要是对13000吨级散货船的局部舱段结构进行横向强度校核，参照设计任务书的对本船的要求，以及所给的船舶主尺度、总布置图和型线图，按照《钢制海船入级规范》（2006）对船体结构进行计算。通过强度校核，该船满足设计任务书的要求并且满足规范和总布置的要求。

Abstract The ship of all steel welded structure, single deck, transom, forward first column of the bulbous bow, single propeller, rudder and short forecastle and poop, direct drive diesel tail type area near Hainan cargo ship, ship with three decks, and is equipped with the ZC approve of steel steel hydraulic folding hatch cover。The ship is equipped with forecastle and tail on the main deck and five deck。The whole ship is in the form of mixed frame。The cargo area of this ship are not provided with the pillar, and the torsion box structure, support hatch end beam。The main structure in accordance with the Chinese classification rules for the construction of domestic voyage ships  (2006) design requirements for offshore。The ship's stern frame spacing to 10 and 176 to a 600mm, the other is 700mm, the bottom of the longitudinal spacing for 665mm。The whole ship general arrangement according to requirements, set around hull through the water and oil dense transverse bulkhead 7, transverse bulkheads are using vertical stiffeners help strong。 In addition, according to the arrangement of the demand sets the local longitudinal, transverse bulkhead number。 The whole ship materials to meet with the CCS (2001) specification requirements of ship steel, bow and stern frame is welded by steel plate。Hull structure welding requirements according to the hull structure welding specification sheet for shipyard shall prepare reasonable welding process, to minimize the distortion caused by welding, welding hull structure welding materials shall be with CCS materials and welding specification (2001) requirements。According to the actual situation of the construction site (the construction site, lifting capacity, construction technology, etc。), the hull structure is pided, the shipyard should be based on the structural characteristics of the ship in advance to develop a reasonable construction technology。All the tanks in the tank, in which the upper and lower components should be opened with water (oil) holes, vent holes。
