Sensors and sensibility

RMSPumptools is developing a specialist, underwater sensor system, proven in the oil and gas sector, for a major nickel mine North East of Australia.

The problem:

On-going production on the Goro Nickel Project active on the Island of New Caledonia depends on water and waste produced by the drilling to flow continuously away from the site to an open-ocean outfall 20km away. This flow was monitored by a sensor previously mounted inside the pipe close to the end of the pipeline and, as such, was vulnerable to damage from fast-flowing debris.

Our solution:

RMSpumptools has applied a specially adapted sensor, mounted outside the pipe to measure the transit of particles within the pipe, transmitting the information back to shore through 20km of cable and SeaConnect Wet Mate Connectors, without the need for signal boosting equipment.

"We took sensors designed for the North Sea oil industry for detecting sand in the flow of oil, and utilised them for this challenging application,"

explains Dave Pye, subsea business development manager at RMSpumptools.

"The sensor system will last longer than previous sensors mounted inside the pipe, and it will also be easier to maintain and replace. The sensor also sends signals long-distance without interruption – something subsea sensors like this have not previously been able to do."

Subsea business manager, Michael Winfield adds,

"We were able to offer a more innovative and all-encompassing solution than our competition, but this development comes as part of our plans to diversify our subsea monitoring product range into other market areas such as renewable energy."
