新技術來了！分分鐘搞定水下設備監測難題

The INTEGRIpod NXT platform has been specifically developed to meet the needs of the offshore oil and gas industry in the current market; offering industry-leading features in a standard, modular format. Along with a range of new features, the new INTEGRIpod platform will support INTEGRIpod’s impressive track record of reliability and robust performance, proved in millions of hours of successful ultra-deepwater subsea operations since the product range launched in 1998.

Typical applications for the INTEGRIpod range include linear displacement and static and dynamic inclination of subsea structures such as BOPs, wellheads, conductor systems, mooring lines, and jumpers. With industry-leading on-board processing capabilities, measured data is processed in real-time and transmitted wirelessly or hardwired enabling instantaneous operational decision-making. The new platform also allows for deployments in excess of one year between battery change-outs due to new features such as ‘Smart Logging,’ which enables the device to deploy and only record phenomena over client-defined thresholds; significantly reducing campaign costs and the need for offshore interventions.

Sandip Ukani, technical director, Pulse, said, “At the core of the new platform is a 32-bit ARM processor, which offers low power consumption with significant on-board processing capability; delivering best-in-class battery life. The on-board MEMS gyroscopic sensors deliver unrivalled precision and accuracy. The platform allows communication over various connectivity options, including hardwired and acoustic, and can communicate over various industry standard open communication standards, such as RS232/485. Additionally, a multitude of connectors allows direct integration of Pulse’s proven sensor family, including the INTEGRIstick (Curvature Sensor), INTEGRIstrain (Custom Bonded Strain Gauge Packages) in addition to any third party sensor package.”

The third generation INTEGRIpod platform underwent extensive sea trials in the harsh weather of the North Sea, and in deepwater offshore Brazil. It is now ready for deployment as part of Pulse’s extensive fleet of structural monitoring systems.

Pulse Structural Monitoring, an Acteon company, is a leader in marine structural monitoring and has been responsible for providing highly successful monitoring systems and services since 1998.

The INTEGRIpod is a motion sensor with integrated data logger for measuring the movement of subsea structures.

Deployment of loggers

The INTEGRIpod contains all electronics, batteries and sensors enclosed in a pressure rated and corrosion resistant casing. They can be deployed by diver or ROV.

The INTEGRIpod can be set up to communicate in the following ways

• 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

System configuration

A wide range of configurations of the INTEGRIpod are available to meet specific requirements. However, there are a number of standard off-shelf configurations optimised 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
