    Abstract: A system (1) for attaching a plurality of seismic nodes (110, 110a) along a main carrier rope (101). The main carrier rope is made of steel or synthetic fibre, and comprises no power or communication lines. The system has a length measuring device (210) for providing a measured length (Lm) of deployed main carrier rope (101); a data source (220, 230, 240) for providing positioning data affecting the rope position of each seismic node (110, 110a) on the main carrier rope (101); a control unit (200) for providing an attachment command whenever the measured length (Lm) corresponds to a rope position of a seismic node (110, 110a) computed from the positioning data; and a node attaching unit (100) for attaching a seismic node (110, 110a) to the main carrier rope (101) in response to the attachment command. The system is capable of attaching nodes (110) with different node spacing between some or all nodes along the main carrier rope (101). As the rope positions are determined by the measured length (Lm), the system automatically compensates for creep or stretch in the main carrier rope (101). Attaching a seismic node (110) to the main carrier rope (101) at any rope position by means of a clamping device, a suspension device and a fly line is also disclosed.

    Abstract translation: 一种用于沿着主承载绳索(101)附接多个地震节点(110,110a)的系统(1)。 主承载绳由钢或合成纤维制成,不包括电源或通讯线。 该系统具有长度测量装置(210),用于提供部署的主承运绳(101)的测量长度(Lm); 数据源(220,230,240),用于提供影响主载架绳索(101)上的每个地震节点(110,110a)的绳索位置的定位数据; 每当测量长度(Lm)对应于从定位数据计算的地震节点(110,110a)的绳索位置时,提供附接命令的控制单元(200) 以及用于响应于附接命令将地震节点(110,110a)附接到主承载绳索(101)的节点附接单元(100)。 该系统能够沿着主运输绳索(101)在一些或所有节点之间附接具有不同节点间隔的节点(110)。 由于绳索位置由测量长度(Lm)决定,系统会自动补偿主载运绳索(101)中的蠕变或拉伸。 还公开了通过夹紧装置,悬挂装置和飞行线将地震节点(110)安装在任何绳索位置处的主承载绳索(101)上。
