Ensuring the safety and integrity of subsea umbilical systems during transportation and installation is critical. The hydraulic tubes and hoses within these systems are fluid-filled, making them vulnerable to environmental changes that can cause significant pressure variations.
These fluctuations pose potential safety risks, including the danger of the umbilical system reaching hazardous pressure levels or collapsing under vacuum conditions.
To address these challenges, flexible pipe experts at The Impulse Group offer a comprehensive Subsea Umbilical Pressure Monitoring System that enhances safety and efficiency. In this blog, we explore the importance of pressure monitoring and delve into the monitoring and testing capabilities of The Impulse Group’s solution.

The importance of pressure monitoring
During the pre-commissioning stages, monitoring the pressure within umbilical systems is essential. Environmental factors can cause fluids within the hydraulic lines to expand or contract, leading to dangerous pressure levels. Without proper monitoring, these changes can pose risks to personnel and the integrity of the umbilical system.
The Impulse Group's manifold options provide tailored solutions to meet diverse project requirements, ensuring that pressure changes are detected and managed effectively.
Advanced monitoring and testing capabilities
The Impulse Group's Umbilical Pressure Monitoring System is designed with space and accessibility in mind. Typically mounted close to the umbilical termination head, the system addresses the constraints of confined spaces on transportation and installation vessels.
Key features include:
Wireless pressure monitoring: Real-time graphical data can be viewed on tablets or personal computers, with a range of up to 800 metres without the need for a booster.
Compact and lightweight design: The system is easy to handle and install, maximising space efficiency.
Bespoke solutions: Each system is customised to meet specific project needs, ensuring optimal performance and reliability.
Before shipment, the umbilical monitoring and testing kit is fully assembled and tested in-house. This ensures that the equipment arrives clean, tested and ready for use.
The system’s wireless monitoring capabilities are extensive, providing robust and flexible solutions for a variety of applications:
Pressure range: 0 to 700 Bar+
Temperature range: -50°C to +200°C
Mobile app compatibility: Free iOS and Android apps for data viewing and logging
Custom project visuals: Create tailored visual representations of data
PC logging software: Free software for Windows PCs, capable of viewing data from up to 100 sensors simultaneously
Data transmission: Up to 800 metres with selectable scanning rates from 5 ms to 60 seconds
Battery powered: Operates on 2xAA batteries
Security features: Password protection and alarm/event triggers for data logging
Pressure relief and modular system
The system supports up to six umbilical lines, with the flexibility to add more lines as needed. It includes a modular pressure relief system and can be configured with various port sizes and fitting types to match project specifications.
The available pressure range for testing extends up to 18,000 psi, accommodating a wide range of operational requirements.
Additional features include:
Fluid sampling ports: Designed to meet cleanliness specifications such as NAS 1638 / ISO 4406:2021
Hydraulic and chemical lines: Conforming to SAE AS 4059 standards for contamination levels
Complete kits: Supplied with backing plates for mounting, valves, hoses, instrumentation, and associated fittings and spares
