Custom Valve Pack for Subsea Pipeline Repair

Overview 

Innova partnered with a customer to deliver a custom valve pack for a remotely operated subsea repair tool, designed for deepwater habitat operations at depths of up to 1000 meters. 

Challenge 

The main challenge was achieving near leak-free performance while handling both water and pressurized air in the same system. This was critical for creating and maintaining a dry habitat, placing strict demands on sealing integrity, reliability, and system robustness. 

Solution 

Innova developed a tailored solution based on its proven PIO36 platform, featuring: 

• Precise control via Ethernet using Modbus TCP 
• Seamless integration with the operator’s system 
• Support for external sensors enabling real-time monitoring and safe operation 

The system was engineered to perform consistently across varying pressures and fluid conditions. 

Result 

A compact and highly reliable valve system that maintains habitat integrity, reduces leakage risk, and enables safe, efficient subsea pipeline repair in demanding environments. 

Key Facts
