Abstract: A method for determining a sail plan for a towed-array marine seismic survey includes: dividing a survey area into a regular grid of tiles; and identifying a subset of the tiles as nodes around which continuously curved sail lines are defined. The nodes define regular pattern further including: a first subpattern of nodes; and a second subpattern of nodes offset from the first subpattern. A method for conducting a towed array marine survey includes: traversing a plurality of continuously curved sail lines across a survey area, each sail line being relative to a node; and acquiring seismic data while traversing the continuously curved sail lines. The set of nodes defining a regular pattern further including: a first subpattern of nodes; and a second subpattern of nodes offset from the first subpattern.

Abstract translation: 一种用于确定拖船阵列海洋地震勘测的航行计划的方法包括：将勘测区域划分成规则的格栅; 以及将所述瓦片的子集识别为围绕其定义连续弯曲的帆线的节点。 节点定义规则模式，进一步包括：节点的第一子模式; 以及从第一子模式偏移的节点的第二子模式。 用于进行拖曳排列海洋勘测的方法包括：穿越测量区域遍历多个连续弯曲的帆线，每条帆线相对于节点; 并且在穿过连续弯曲的帆线的同时获取地震数据。 定义规则模式的节点集还包括：节点的第一子模式; 以及从第一子模式偏移的节点的第二子模式。
