摘要： A method and system are provided for use in marine seismic data surveys to increase fold and offset without increasing streamer length or drag on the streamer boat. Generally the method comprises the use of a second source boat positioned in the steamer path and firing the second source at a time before the recording of information from the first source is finished. By positioning the second source about one streamer length in front of the closest hydrophone, the fold is increased by two for the same length streamer.

摘要： System for controlling cables and streamers in a seismic tow arrangement comprising at least one deflector (13) connected to one side of a tow vessel (10) via at least one wire (12), leading or the like, wherein the deflector is located in a position at a distance perpendicularly to the direction of movement (5) of the tow vessel, the vessel being equipped with a navigation system for measuring the position of the vessel. The system is characterised by comprising a command unit and a number of control units, where the control units are located on at least some of the streamers and are adapted to measure and report about their positions, that the command unit comprises means for receiving the position information from each individual control unit and calculation of possible deviations from predetermined positions, and that the system comprises means for changing the position of the streamers for re-establishing the positions of the control units.
摘要翻译：用于在地震牵引装置中控制电缆和拖缆的系统，包括经由至少一根导线（12），引导件等连接到丝束容器（10）的一侧的至少一个偏转器（13），其中偏转器位于在与渔船的移动方向（5）垂直的距离处的位置，船舶配备有用于测量船舶位置的导航系统。该系统的特征在于包括命令单元和多个控制单元，其中控制单元位于至少一些拖缆上并适于测量和报告其位置，指令单元包括用于接收位置的装置来自每个单独控制单元的信息和计算与预定位置的可能偏差，并且该系统包括用于改变拖缆的位置以重新建立控制单元的位置的装置。
