Published on

Seatooth® PipeLogger is a pipe mounted sensor that measures temperature data at the pipe surface under a thermal insulating ‘cover’ to ensure core pipe temperature.
Seatooth® PipeLogger is a wireless SCADA platform for subsea pipelines and risers.
It supports a range of non-penetrating sensors including temperature, wall thickness, vibration, and flow. Data is stored locally for wireless upload by ROV, diver or AUV. Alternatively, 2-way wireless communications can be provided with a nearby control system or to a remote platform using Seatooth or hybrid Seatooth/Acoustic communications.
