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

Theme:  Lessons learned in the Subsea & New Energy Space
Date:      Wednesday, 15 October 2025
Time:     5.30 – 8.30pm AWST
Venue:  Parmelia Hilton Perth

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

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

Management of CCS Pipeline Networks: State of the Art
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.

THE SOCIETY FOR UNDERWATER TECHNOLOGY INVITE YOU TO THE AUGUST 2025 EVENING TECHNICAL MEETING

THEME: ADVANCES IN PIPELINE TECHNOLOGY & DESIGN

---

PROGRAMME: 

• 5.30 pm – 5.55 pm Registration
• 6.00 pm – 7.30 pm Presentations
• 7.30 pm – 8.30 pm Networking drinks & nibbles

The evening will focus on the following topics:

1. HPHT Deepwater Pipeline Design Using 3D FEA on a Fast Track Project
by Matt Davis, SEA Global

Subsea pipeline design has traditionally used simplified, discrete finite element models to characterise the in-place mechanical response to load effects such as temperature, pressure and geohazards. This often necessitates assumptions or simplifications with respect to the actual mechanical response of a subsea pipeline system. Specifically, the use of 3D seabeds has typically been out of reach for effective use in project design.

A combination of automated engineering workflows and relational databasing have been used to overcome these traditional limitations, by enabling submarine pipeline design in FEA to be performed on 3D seabeds, at scale and on reduced timeframes. For projects with challenging seabeds, global buckling, walking and geohazards, this methodology provides a pathway for efficient engineering solutions.

The presentation will share the engineering solutions for a project that recently completed Detailed Design, demonstrating the success of this modernised approach to submarine pipeline design.

 

2. Qualification of Large Diameter Seamless Pipe Manufacture for Buckle Arrestors
by Stuart Folkard, Wood

Buckle arrestors used in subsea pipelines are generally fabricated from thicker walled pipe than is used for the rest of the pipeline. The heavier pipe thickness is often at or exceeds the manufacturing limit of traditional LSAW pipe making processes such as JCOE or UOE, leaving the only options as being three-roll press forming or forging. A recent project considered seamless pipe manufacture for the large diameter, heavy wall thickness buckle arrestor pipe required. The seamless manufacturing route had advantages of cost and delivery schedule over the alternative method of forging.
This presentation describes the qualification undertaken to confirm the suitability of the seamless manufacturing process for production of pipe for buckle arrestors.

3. Water-borne Erosion of Reinforced Polymer Composites: Application to Shallow Offshore Marine Environment
by Ali Al-Darraji, Curtin University

Offshore pipelines are increasingly subjected to severe erosion due to sand-laden water flows, especially in shallow marine environments. Conventional steel pipeline systems require costly maintenance and replacement, prompting investigation into advanced composite liner technologies. This research explores advanced polymer composite technologies, specifically carbon fibre-reinforced polymer (CFRP) and glass fibre-reinforced polymer (GFRP), as innovative solutions to enhance pipeline erosion resistance and reduce lifecycle costs in marine environments.

Through experimental testing simulating real-world marine conditions, including variable flow velocities, sand particle concentrations, and impact angles relevant to pipeline geometries, the study highlights the superior erosion resistance and durability of CFRP over GFRP. Notably, CFRP maintained structural integrity under high-velocity impacts at oblique angles, making it particularly suitable for critical pipeline sections like bends and tie-ins.

An empirical erosion prediction model was developed to assist engineers in material selection and pipeline design, enabling lifecycle cost reductions and enhanced asset integrity. This work presents actionable insights for offshore pipeline engineers, focusing on integrating advanced composites into pipeline design frameworks to address erosion, reduce maintenance, and improve long-term reliability.

We’ll have three topics on the evening:

1. Role of wave energy in future renewable grids Dr Jana Orszaghova, UWA The coast from Perth to Hobart and beyond experiences persistent, year-round ocean waves. Wave energy technologies designed to harness this energy are under development, but are currently too expensive to compete with solar and wind installations. However, as renewable penetration increases, wave energy could be a valuable addition to the future energy mix thanks to its complementary nature – wave energy peaks in the winter when solar energy dips. This talk will outline the benefits of combined wave-wind-solar grids, quantified in terms of reduced future energy storage requirements and lower CapEx. 2. Leveraging Oil and Gas Industry Experience for Sustainable Wave Energy: The D-Spar Technology Tim Green, WaveX WaveX is revolutionising wave energy production through its proprietary D-Spar technology. At its core, the D-Spar device utilises spar buoy design and mooring configurations that are adapted from innovations in the oil and gas Industry. In this presentation, we will discuss how technologies developed in the offshore oil and gas industry have laid the foundation for upcoming new energies. We will demonstrate how the systematic qualification approach borrowed from the oil and gas industry significantly reduces technical and financial risks, potentially accelerating industry-wide adoption of wave energy technologies. 3. The M4 Wave Energy Deployment in Albany Dr Hugh Wolgamot, UWA In November 2024 a 24m-long wave energy prototype called M4 was launched in King George Sound, Albany.  The reduced-scale prototype operated throughout summer, collecting data on power, motions, mooring loads and more.  Funded by the Blue Economy CRC, WA State Government and UWA, this project aimed to crystallise multiple benefits around the central mission of deploying an open-source wave energy converter.  This is the story of the project, from inception to retrieval, including insights into performance, outcomes and lessons learned.  The presentation will also touch on procurement and the (local) fabrication and operations.
