This year’s Subsea Expo 2025 was an exciting platform for the industry, with increased engagement and enthusiasm across various sectors.
Derek Mason, Sales Manager at CSS Subsea Distribution, stated, “There was significant interest across all of our business units, with clients keen to understand more about our high-performance subsea valves portfolio.”
Our team also had the privilege of participating in interviews and technical presentations, contributing valuable insights on our latest subsea technology advancements and suitability to energy security and transition applications.
Pioneering Subsea Ball Valve Technology


A key highlight at Subsea Expo 2025 was the overwhelming interest in our subsea small-bore ball valves–the world’s first 2″ metal and soft-seated small-bore ball valves rated at 15 ksi.
Why Our Subsea Ball Valves Stand Out
- Ultra-compact design for minimal weight and optimised efficiency.
- Industry-leading pressure rating of 15 000 psi, ensuring reliability in harsh environments.
- Reduced leakage paths, improving system integrity and operational safety.
This portfolio sets a new industry benchmark for subsea distribution systems, addressing the growing demand for high-performance, efficient and lightweight valve solutions.
Exclusive Interview with CSS’ Andrew Woodward
Andrew Woodward, Sales Director of our Deepwater Solutions division, was interviewed by Global Underwater Hub to discuss our experience in energy security and energy transition.
The conversation focused on:
- MORGRIP® Diverless Connectors, the preferred solution for subsea pipeline repairs for over 35+ years.
- CSS’ involvement in early Carbon Capture and Storage (CCS) projects, where we adapted our connector products to suit carbon applications.
Addressing Key Challenges in Carbon Capture Applications:
Andrew emphasised CSS’ role in solving fluid aggressiveness concerns in carbon capture systems. Our solutions have now been successfully deployed for a major project, reinforcing our expertise in subsea pipeline integrity.

Subsea Power Systems Innovation: ROV Electrification


Another milestone at Subsea Expo 2025 was our presentation on subsea power distribution systems, delivered by Richard Wright, Engineering Manager at CSS Isotek.
Richard’s presentation, “Development and Testing of Electric Work Class ROV Power Systems,” sparked industry-wide interest in:
- ROV power system advancements
- Electrification in subsea operations
- Efficiency improvements for deepwater applications
CSS continues to drive innovation in subsea electrification and control systems development.
