Subsea Data Loggers

INTEGRIpod™ with chain interface

The INTEGRIpod™ is a versatile subsea data logger that integrates with various sensors for measuring the acceleration, angular rate, inclination, strain, curvature, load, depth, temperature, pressure, etc, of subsea structures.

The INTEGRIpod™ utilises one of three communication schemes to handle data:

• Standalone - to save data on to on-board memory for later retrieval to achieve off-line monitoring
• Acoustic - to transmit data using a through water acoustic link to achieve real-time monitoring
• Hardwired - to transmit data via umbilical to achieve real-time monitoring

INTEGRIpod™ has a compact, pressure rated and corrosion resistant casing. It also provides connection ports for external sensors or communication links. A wide range of deployment interfaces are available to enable the data logger to be installed to any target subsea structure. Software is also provided with all INTEGRIpod™ products.

A wide range of configurations are available to meet specific requirements. However, there are a number of standard off-shelf configurations optimized to meet common applications. Typical applications for the INTEGRIpod™ include:

• Vibration monitoring for risers, pipelines and subsea jumpers (VIV and flow-induced vibration)
• Motion monitoring of subsea structures during installation
• Inclination measurement of drilling riser and SCRs
• Motion and tension monitoring of mooring lines

Multiple INTEGRIpods™ can be deployed along a riser to capture riser response by measuring acceleration and angular rate. These can be either standalone or on-line systems. The flexibility of the INTEGRIpod™ coupled with 2H Offshore’s knowledge of riser response and signal processing allows us to design and supply complete monitoring systems that work reliably and deliver value.
