The invention discloses a segmental division and construction method for a bow part of a liquid ammonia transport ship. The segmental division and construction method comprises the following steps: a, dividing a main deck and a forecastle deck structure into segments; b, the subsection is split into two layers of deck platforms to be assembled; c, fitting-out parts are installed in the segmented assembling stage; d, assembling, welding and forming the sections, and hoisting and unloading the mould; e, taking a forecastle deck as a base plane to carry out blank setting at the initial stage of segmentation, and then carrying out sanding and painting operation; f, turning over the sections by 180 degrees after coating is finished, hoisting the large equipment facilities into the mounting positions of the main decks of the sections from the process holes, and then remounting the process holes; and g, the sections in the normal positions are transported and transferred to a slipway closure site, and a gantry crane is used for hoisting and closure. The structural integrity of the chain locker, the chain pipe and the anchor chock/anchor recess in the main deck and forecastle deck area can be guaranteed, construction of related structures can be completed in the segment preceding stage, the process is advanced, the construction efficiency is improved, the slipway period is shortened, and the construction cost is saved.

    本发明公开了一种液氨运输船艏部分段划分及建造方法,包括以下步骤:a、将主甲板和艏楼甲板结构划分成一个分段;b、将分段拆分成两层甲板平台中组立;c、舾装件在分段组立阶段安装;d、将分段装配焊接成型,吊装下胎;e、分段初始阶段以艏楼甲板为基面进行下胎,之后打砂油漆作业;f、涂装结束后将分段翻身180°,从工艺孔将大型设备设施吊装进入分段主甲板安装位置,之后回装工艺孔;g、将处于正态位置的分段运输转运到船台合拢场地,使用龙门吊吊装合拢。本发明可保证主甲板和艏楼甲板区域的锚链舱、锚链管、锚台/锚穴结构完整性,在分段先行阶段可完成相关结构的施工,工序前移,提高施工效率,节省船台周期,节约建造成本。
