WFS Technologies (WFS), producer of underwater wireless instrumentation and control solutions to the offshore oil and gas and renewables industries, announced the launch of Seatooth PipeLogger Thermal Insulation (TI), an asset integrity monitoring and flow assurance product designed to reduce the cost of monitoring process temperature of subsea pipelines and jumpers with up to two inches of thermal insulation.
The Seatooth PipeLogger TI incorporates an RTD (Resistance Temperature Device) housed in a novel mount designed to trap heat from the insulated pipeline. Process temperature is measured without penetration of thermal insulation or pipe wall. Each system is calibrated to provide an accuracy of better than 10 percent and repeatability of better than 2DegC. An integrated data logger records process and seawater temperature.
Data is harvested wirelessly by diver, ROV or AUV using Seatooth subsea radio. Alternatively, the system can be configured to provide real time data through a Seatooth-enabled Subsea control module (SCM). The wireless communications range of standard Seatooth devices through seawater, the seabed, concrete blankets and the splash zone is 5-10 meters. Wireless communications range can optionally be extended to 35 meters through seawater or 150 meters through the splash zone.
The Seatooth PipeLogger TI incorporates Seatooth Endure, innovative technology designed to extend the battery life of subsea wireless systems to up 15 years.
Systems are depth rated to 200 meters or 1,000 meters, are compact and weigh less than 5 kilograms in seawater. They are suitable for deployment by mini-ROV operating off a rig or small vessel or by diver. Deployment and recovery is facilitated by use of diver straps or ROV clamp. An optional protection cover is available for systems buried in the seabed, under concrete blankets or under rubble.
Target applications include subsea pipeline temperature profile monitoring, upheaval buckling monitoring, replacement of broken process temperature sensors and over-temperature monitoring of flexible.
According to WFS, the subsea asset integrity monitoring and flow assurance product Seatooth PipeLogger TI can reduce the typical installation cost of temperature monitoring on thermally insulated pipelines by over 90 percent.
