ROV deployment offers proven repeatability for 4D reservoir monitoring. The small size allows for more nodes per skid, improving efficiencies. The scalable, automated handling system and software, combined with hands-free data download, deliver an unrivaled speed of operations.

< obn是如何工作的？ > 一、流程简述. 利用 水下机器人 将自备电源的obn布置在海底→接收地震波→回收obn→下载数据并进行处理和解释。 右上角rov工作船负责布置海底节点；左上角的震源船释放地震波；海底节点接收信号. 二、细说流程. 2.1 准备工作

其中,无人缆控潜水器(Remote Operated Vehicle,ROV)通过光电复合缆实现水下与水面的实时通讯与动力传输,具有较大的负载能力、可拓展性和较强的可操控性,可实现长时间连续水下工作。 相比较于传统的潜水作业方式,ROV具有下潜深、成本低、安全性好等优点,借助于高精度的水声定位技术,可满足OBN的高精度节点布设要求。 本文主要结合作业级ROV 在非洲东海岸1次OBN节点布设中的应用实例,探讨基于ROV的水下节点布设技术的可行性,为后续国内开展海底地震节点布设 …

rov友好式obn释放系统及rov布放操作方式，基于rov友好式设计理念，按设计的操作方式可安全、快捷地从释放 系统中取出OBN，实现在水下连续不间断地布放，避免频繁回收释放ROV造成时效延误，从而大幅提高ROV精确布放

Deep Water OBN. In the deep-water environments, SAExploration configures a typical survey crew with a single certified DP-2 classed Construction Support Vessel (CSV) staffed and equipped for twin work-class ROV operations, which is supplemented with an industry seismic source vessel configured and tuned to specific source signature requirements.

Geo Oceans completed an 85-day ROV campaign providing Mini-ROV support for a large OBN seismic survey offshore of Malaysia.

The resulting data showed a clear uplift over that acquired previously using ocean bottom cable (OBC) equipment and was a forerunner to the extensive volume of OBN surveys that have been acquired worldwide in both deep water, using ROVs for deployment, and shallower water depths where both node-on-a-rope (NOAR) and node-on-a wire (NOAW) systems ...

This paper introduces a bespoke ROV-friendly OBN launch and recovery system (LARS). Based on an ROV-friendly design concept, a large number of OBNs can be safely and quickly taken out from the launch and recovery system and deployed by the ROV in quick successions.

因为ROV单次下水可携带的OBN数量有限，这严重制约了ROV精确布放OBN的效率，此文结合实际工程案例介绍了一种专门设计的ROV友好式OBN释放系统及ROV布放操作方式，基于ROV友好式设计理念，按设计的操作方式可安全、快捷地从释放系统中取出OBN，实现在水下连续不间断地布放，避免频繁回收释放ROV造成时效延误，从而大幅提高ROV精确布放OBN的效率。

2020年7月3日 · 由于无人缆控潜水器（Remote Operated Vehicle，ROV）对海洋环境的良好适应性和强大的工程干预能力，为探索海底地震节点布设提供了新方法。 笔者综合介绍了ROV的技术特点，结合具体工程实例讨论了基于ROV的海底地震节点布设的主要技术流程。
