October ETM - Lessons Learnt in Subsea and New Energy

The Society for Underwater Technology invite you to the October 2025 Evening Technical Meeting:

The evening will focus on the following three topics:

1. Lessons Learned Within Subsea: Leveraging Monitoring, Connectivity and Data for Robust Asset Integrity Management

by Thomas McCudden, Viper

Subsea electrical integrity is critical to asset longevity, reliability and safety. Drawing on more than a decade of global monitoring experience, this presentation explores how data-driven strategies can improve reliability, reduce intervention needs and extend asset life. Extensive installation data shows that insulation resistance (IR) degradation rarely occurs without early warning. Detecting subtle trends from day one, and acting early, delivers far better recovery outcomes. These findings support a wider industry shift toward integrated monitoring and condition-based maintenance, reducing reliance on reactive or time-based practices. The session will outline the technical and strategic value of proactive asset management and demonstrate how digital connectivity and condition-based intervention approaches are shaping the future of subsea reliability.

2. The fatigue life of flexible risers is a critical factor in offshore system design due to inherent safety implication

by Dr Craig Booth, Atteris

Breaches in the outer sheath need to be accounted for during design as the annulus environment alters the applicable SN curves used for fatigue calculations and can significantly affect the riser’s predicted fatigue life. The presenter will discuss impact of key parameters investigated to optimise fatigue life predictions, including operating pressure and temperature, inter-layer friction, annulus condition and current loading. Global riser and local fatigue analyses were conducted using OrcaFlex and BFLEX, respectively. Automation tools enabled concurrent operation of both software packages, improving efficiency, and facilitating a comprehensive sensitivity analysis across various operational conditions to optimise the fatigue performance prediction of the riser. The outcome of the assessment provides actionable insights into unbonded flexible riser fatigue life optimisation and management.

3. Management of CCS Pipeline Networks: State of the Art

by Callum Peace, Wood PLC

Large-scale Carbon Capture and Storage (CCS) hubs offer a cost-effective way for industries to reduce CO₂ emissions. Designing CCS systems for multiple emitters presents challenges, including selecting appropriate design codes in a changing regulatory landscape and managing impurities that affect CO₂ properties, phase behaviour, and water dew point.

This presentation explores industry knowledge and tools for CO₂ pipeline network design and operation, including:

• Key outputs from Wood’s Joint Industry Project on CO₂ specification,
• Updates to pipeline design codes and standards,
• Technical readiness of CO₂ subsea equipment.
• As well as emerging insights into corrosive phase development and chemical reactions.

Successful design and management of complex multi-emitter CO₂ pipeline systems require collaboration across disciplines such as pipelines, materials, flow assurance, safety, and process. The presentation highlights essential industry enablers and resources supporting this integrated approach.
