Allseas Selected Pipe-Logger for Major Subsea Pipeline Project

Allseas installed WFS Technologies’  Seatooth Pipelogger for the real time measurement of process temperature on a subsea pipeline system. The pipeline system is designed to have a total gas throughput capacity of 31.5 Bcm per year. 

WFS Technologies’ Pipelogger is a real-time, wireless technology which requires little maintenance and can operate at depths of up to 1.24 miles (2,000 meters) without the need for periodic ROV inspection, contributing toward reducing operating cost, while monitoring process conditions to optimize gas delivery parameters.

The new Mark III generation of Pipeloggers feature a hot-swappable sensor configuration as well as the capability to create subsea cloud networks for real-time analytics at the edge.  

WFS Technologies is an industry pioneer of the subsea internet of things (SIoT) devices.

“By combining our proven Seatooth technology with the ability to hot-swap components, we are able to future proof the installation by enabling the simple addition of capability as the requirement emerges,” said Commercial Director Moray Melhuish. “This can include ultrasonic flow, vibration, cathodic protection status, ultrasonic thickness and met ocean conditions, as well as the initial requirement – in this case, the monitoring of process temperature.”

The wireless, subsea device is designed to deploy multiple sensors and devices on subsea pipelines, trees, risers and manifolds.

According to WFS, it is a cost-effective alternative to hard-wired systems for production, flow and asset integrity monitoring and calibration. P&GJ
