This paper focuses on recent innovations in the methods used for external remote subsea pipeline inspection. An unmanned method is revealed, in which an Autonomous Underwater Vehicle (AUV), paired with an Unmanned Surface Vessel (USV) was utilised to complete inspections. Results are presented from a recent project, in which existing hardware and software were integrated and combined with automated workflows to form a solution, involving an AUV operated from a USV, with operations remotely controlled from shore. As inspection data was acquired, self-actuating workflows ran onboard the AUV, enabling data processing tasks to commence and QC messages/alerts to be transmitted to the control centre, this allowed execution of in-water mission adjustments. The primary focus of this paper is on the development and implementation of an automated, fully unmanned system for subsea inspection operations. Initially, a brief review is presented of recent developments in this field. Links are drawn between these wider developments and progress made within the project, and areas are highlighted where further work is required for realisation of a comprehensive unmanned pipeline inspection solution.

本文重点介绍用于外部远程海底管道检查方法的最新创新。揭示了一种无人方法，其中利用自主水下航行器（AUV）与无人水面舰艇（USV）配对来完成检查。结果来自最近的一个项目，其中现有的硬件和软件被集成并与自动化工作流程相结合，形成了一个解决方案，涉及由 USV 操作的 AUV，从岸上远程控制操作。获取检查数据后，自动执行工作流在 AUV 上运行，使数据处理任务能够开始，QC 消息/警报被传输到控制中心，这允许执行水中任务调整。本文的主要重点是开发和实施自动化的、用于海底检查操作的完全无人系统。首先，简要回顾了该领域的最新发展。将这些更广泛的发展与项目中取得的进展联系起来，并强调了需要进一步工作以实现全面的无人管道检查解决方案的领域。
