Subsea Umbilical Pressure Monitoring System

TIG_20~2

Safely Handle Umbilicals with our Monitoring & Testing System

During the transportation and installation stages of a newly manufactured umbilical system, the hydraulic tubes and hoses within the system are fluid filled and can therefore be susceptible to external environmental changes. These changes can lead to an expansion or contraction of the fluids, resulting in large pressure changes in the umbilical which could pose a safety risk to nearby personnel, as the umbilical system is heated to dangerous pressures levels. Negative pressures, due to a temperature drop, could also lead to the umbilical collapsing under a vacuum within the fluid filled lines.

Pressure monitoring is therefore essential during these stages of pre-commissioning and The Impulse Group can offer a selection of manifold options to meet a wide range of requirements.

Monitoring & Testing System Capabilities

As the monitoring & testing systems are usually mounted close to the umbilical termination head, access and space constraints are almost always a concern. The Impulse Group Umbilical Pressure Monitoring System offers wireless pressure monitoring that provides real time graphical data that can be viewed on a tablet or personal computer. With up to 800m  range without need for a booster, the system provides the necessary pressure monitoring within congested spaces typical of transportation and installation vessels.

The equipment is designed to make the most efficient use of space, and if offered in a compact lightweight design to ease handling and installation. The Impulse Group offers the flexibility of  each system being bespoke to the project’s specific requirements.

The umbilical monitoring and testing kit will be fully assembled and tested in house, prior to shipment where they will arrive tested, cleaned and ready for mounting/use.
