WFS Technologies (WFS), a provider of underwater wireless instrumentation and control solutions, has announced the launch of Seatooth PipeLogger Thermal Insulation (TI). Designed to deliver a step reduction in the cost of monitoring process temperature of subsea pipelines and jumpers with up to 2in 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% and repeatability of better than 2°C. 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 5-10m. Wireless communications range can optionally be extended to 35m through seawater or 150m through the splash zone.
The Seatooth PipeLogger TI incorporates Seatooth Endure, a technology designed to extend the battery life of subsea wireless systems to up 15 years.
Systems are depth rated to 200m or 1000m, and weighs under 5kg 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 flexibles.
