Session title: Subsea Inspection, Maintenance & Repair (IMR)

This session is devoted to autonomous unmanned systems developed for subsea inspection, maintenance and repair (IMR).  The technology gaps and operational risk profile for pipeline and infield inspections will be discussed in the context of green and brown fields. The speakers will highlight how their organisations are developing and de-risking enabling technology that have strong impact on the cost and efficiency of IMR workflows: planning, sensor fusion, localisation and mapping, command & control, communication enablers, human-machine interaction, power management and analytics for anomaly/event detection.                                                                                     

Session Moderator: Sepand Ossia, Robotics Research Director, Schlumberger

1400-1415: Transforming Underwater Vehicle Services Through Autonomy and New Deployment Methods

James Jamieson, Global Technical Sales, i-Tech Services  


Subsea Inspection Repair and Maintenance (IRM) services have traditionally been vessel-based, relying on Remotely Operated Vehicles (ROV) or Diver operations. The industry challenge to reduce costs is driving the development of new working practices, leveraging the latest in communications, system electrification and autonomous technologies to enhance underwater vehicle capability. 

The recent focus on the development onshore ROV Control Centers and high speed survey vehicles are examples of bringing significant but incremental savings, which is not sustainable in the long-term; a more innovative approach is required that practically eliminates the need for the support vessel, whilst managing the risk in continued operations.

Several developments are underway toward field resident hybrid ROV/AUV systems capable of a wide range of IMR tasks. These systems target benefits beyond cost reduction - enabling digitalization and condition based monitoring, reduced environmental impact, reduced HSE Risk and increased production efficiency. 

This paper demonstrates how vehicles such as i-Tech Services’ Autonomous Inspection Vehicle (AIV) bring to market key technology pillars to deliver the service benefits being targeted. These technologies, demonstrated in several offshore campaigns, include novel deployment and launch methods, subsea docking, and a range of flight control modes from semi-automatic piloted for intervention tasks to full autonomy for extended range and routine surveillance.
