轴系中心线的确定
Decide the centerline of the shaftline.
1）采用工具
Tools and instrument
激光经纬仪、光靶。Laser theodolite and optical target.
2）轴系中心线的确定的条件
Decided condition the centerline of the shaftline.
轴系中心线的确定应根据季节温度变化来进行，夏天一般在晚上8-9点进行,冬天一般在下午5点左右进行, 或在阴天进行，在轴系中心线的确定过程中，船上不应有能够导致船体变形的工作在进行。从机舱前壁到船的尾部，从机舱二甲板到双层底舱的主船体结构焊接及火工矫正工作全部结束。两根中间轴必须吊运至机舱临时固定，同时主机主体
必须根据轴系布置图上的尺寸位置大致就位。主机就位前必须初步确定轴系中心线，然后根据确定的轴系中心线在主机凹槽后端面和尾管前端面之间设置两个临时支架，把FR59肋位上光点引到临时支架上并打硬记。
This step should be done according to temperature change of the season of a year , in the estival season , this work should be done at evening 8-9 clock, and in the winterly season, this work should be done at afternoon 5 clock ,or in the cloudy day, and any work that can bring hull deformation should be stopped. all the welding and the fire rectification work from fore bulkhead of engine room to stern and from engine room second deck to double bottom must be finished. two intermediate shaft must be lifted to engine room and located temporary . and the M/E main body must be located in accordance with the shaft arrangement drawing. we must decide the shaft line in advance ,then set two temporary support between M/E groove end and the fore surface of stern tube according to the centerline of the shaft lin
